(C. W. W.; J. G. C. A.)

CAESAREAN SECTION, in obstetrics (q.v.) the operation for removal of a foetus from the uterus by an abdominal incision, so called from a legend of its employment at the birth of Julius Caesar. This procedure has been practised on the dead mother since very early times; in fact it was prescribed by Roman law that every woman dying in advanced pregnancy should be so treated; and in 1608 the senate of Venice enacted that any practitioner who failed to perform this operation on a pregnant woman supposed to be dead, laid himself open to very heavy penalties. But the first recorded instance of its being performed on a living woman occurred about 1500, when a Swiss pig-gelder operated on his own wife. From this time onwards it was tried in many ways and under many conditions, but almost invariably with the same result, the death of the mother. Even as recently as the first half of the 19th century the recorded mortality is over 50%. Thus it is no surprise that craniotomy—in which the life of the child is sacrificed to save that of the mother—was almost invariably preferred. As the use of antiseptics was not then understood, and as it was customary to return the uterus to the body cavity without suturing the incision, the immediate cause of death was either septicaemia or haemorrhage. But in 1882 Saenger published his method of suturing the uterus—that of employing two series of sutures, one deep, the other superficial. This method of procedure was immediately adopted by many obstetricians, and it has proved so satisfactory that it is still in use today. This, and the increasing knowledge of aseptic technique, has brought the mortality from this operation to less than 3% for the mother and about 5% for the child; and every year it is being advised more freely for a larger number of morbid conditions, and with increasingly favourable results. Craniotomy, i.e. crushing the head of the foetus to reduce its size, is now very rarely performed on the living child, but symphysiotomy, i.e. the division of the symphysis pubis to produce a temporary enlargement of the pelvis, or caesarean section, is advocated in its place. Of these two operations, symphysiotomy is steadily being replaced by caesarean section.

This operation is now advised for (1) extreme degrees of pelvic contraction, (2) any malformation or tumour of the uterus, cervix or vagina, which would render the birth of the child through the natural passages impossible, (3) maternal complications, as eclampsia and concealed accidental haemorrhage, and (4) at the death of the mother for the purpose of saving the child.

CAESAREA PALAESTINA, a town built by Herod about 25-13 B.C., on the sea-coast of Palestine, 30 miles N. of Joppa, on the site of a place previously called Tunis Stratonis. Remains of all the principal buildings erected by Herod existed down to the end of the 19th century; the ruins were much injured by a colony of Bosnians established here in 1884. These buildings are a temple, dedicated to Caesar; a theatre; a hippodrome; two aqueducts; a boundary wall; and, chief of all, a gigantic mole, 200 ft. wide, built of stones 50 ft. long, in 20 fathoms of water, protecting the harbour on the south and west. The harbour measures 180 yds. across. The massacre of Jews at this place led to the Jewish rebellion and to the Roman war. Vespasian made it a colony and called it Flavia: the old name, however, persisted, and still survives as Kaisarieh. Eusebius was archbishop here (A.D. 315-318). It was captured by the Moslems in 638 and by the Crusaders in 1102, by Saladin in 1187, recaptured by the Crusaders in 1191, and finally lost by them in 1265, since when till its recent settlement it has lain in ruins. Remains of the medieval town are also visible, consisting of the walls (one-tenth the area of the Roman city), the castle, the cathedral (now covered by modern houses), and a church.

(R. A. S. M.)

CAESAREA PHILIPPI, the name of a town 95 miles N. of Jerusalem, 35 miles S.W. from Damascus, 1150 ft. above the sea, on the south base of Hermon, and at an important source of the Jordan. It does not certainly appear in the Old Testament history, though identifications with Baal-Gad and (less certainly) with Laish (Dan) have been proposed. It was certainly a place of great sanctity from very early times, and when foreign [v.04 p.0944] religious influences intruded upon Palestine, the cult of its local numen gave place to the worship of Pan, to whom was dedicated the cave in which the copious spring feeding the Jordan arises. It was long known as Panium or Panias, a name that has survived in the modern Banias. When Herod the Great received the territory from Augustus, 20 B.C., he erected here a temple in honour of his patron; but the re-foundation of the town is due to his son, Philip the Tetrarch, who here erected a city which he named Caesarea in honour of Tiberius, adding Philippi to immortalize his own name and to distinguish his city from the similarly-named city founded by his father on the sea-coast. Here Christ gave His charge to Peter (Matt. xvi. 13). Many Greek inscriptions have been found here, some referring to the shrine. Agrippa II. changed the name to Neronias, but this name endured but a short while. Titus here exhibited gladiatorial shows to celebrate the capture of Jerusalem. The Crusaders took the city in 1130, and lost it to the Moslems in 1165. Banias is a poor village inhabited by about 350 Moslems; all round it are gardens of fruit-trees. It is well watered and fertile. There are not many remains of the Roman city above ground. The Crusaders' castle of Subeibeh, one of the finest in Palestine, occupies the summit of a conical hill above the village.

(R. A. S. M.)

CAESIUM (symbol Cs, atomic weight 132.9), one of the alkali metals. Its name is derived from the Lat. _caesius_, sky-blue, from two bright blue lines of its spectrum. It is of historical importance, since it was the first metal to be discovered by the aid of the spectroscope (R. Bunsen, _Berlin Acad. Ber._, 1860), although caesium salts had undoubtedly been examined before, but had been mistaken for potassium salts (see C.F. Plattner, _Pog. Ann._, 1846, p. 443, on the analysis of pollux and the subsequent work of F. Pisani, _Comptes Rendus_, 1864, 58, p. 714). Caesium is found in the mineral springs of Frankenhausen, Montecatini, di Val di Nievole, Tuscany, and Wheal Clifford near Redruth, Cornwall (W.A. Miller, _Chem. News_, 1864, 10, p. 181), and, associated with rubidium, at Duerkheim; it is also found in lepidolite, leucite, petalite, triphylline and in the carnallite from Stassfurt. The separation of caesium from the minerals which contain it is an exceedingly difficult and laborious process. According to R. Bunsen, the best source of rubidium and caesium salts is the residue left after extraction of lithium salts from lepidolite. This residue consists of sodium, potassium and lithium chlorides, with small quantities of caesium and rubidium chlorides. The caesium and rubidium are separated from this by repeated fractional crystallization of their double platinum chlorides, which are much less soluble in water than those of the other alkali metals (R. Bunsen, _Ann._, 1862, 122, p. 347; 1863, 125, p. 367). The platino-chlorides are reduced by hydrogen, and the caesium and rubidium chlorides extracted by water. See also A. Schroetter (_Jour. prak. Chem._, 1864, 93, p. 2075) and W. Heintz (_Journ. prak. Chem._, 1862, 87, p. 310). W. Feit and K. Kubierschky (_Chem. Zeit._, 1892, 16, p. 335) separate rubidium and caesium from the other alkali metals by converting them into double chlorides with stannic chloride; whilst J. Redtenbacher (_Jour. prak. Chem._, 1865, 94, p. 442) separates them from potassium by conversion into alums, which C. Setterberg (_Ann._, 1882, 211, p. 100) has shown are very slightly soluble in a solution of potash alum. In order to separate caesium from rubidium, use is made of the different solubilities of their various salts. The bitartrates RbHC_4H_40_6 and CsHC_4H_40_6 have been employed, as have also the alums (see above). The double chloride of caesium and antimony 3CsCl.2SbCl_3 (R. Godeffroy, _Ber._, 1874, 7, p. 375; _Ann._, 1876, 181, p. 176) has been used, the corresponding compound not being formed by rubidium. The metal has been obtained by electrolysis of a mixture of caesium and barium cyanides (C. Setterberg, _Ann._, 1882, 211, p. 100) and by heating the hydroxide with magnesium or aluminium (N. Beketoff, _Chem. Centralblatt_, 1889, 2, p. 245). L. Hackspill (_Comptes Rendus_, 1905, 141, p. 101) finds that metallic caesium can be obtained more readily by heating the chloride with metallic calcium. A special V-shaped tube is used in the operation, and the reaction commences between 400 deg.C. and 500 deg.C. It is a silvery white metal which burns on heating in air. It melts at 26 deg. to 27 deg.C. and has a specific gravity of 1.88 (15 deg.C.).

The atomic weight of caesium has been determined by the analysis of its chloride and bromide. Richards and Archibald (Zeit. anorg. Chem., 1903, 34, p. 353) obtained 132.879 (O=16).

_Caesium hydroxide_, Cs(OH)_2, obtained by the decomposition of the sulphate with baryta water, is a greyish-white deliquescent solid, which melts at a red heat and absorbs carbon dioxide rapidly. It readily dissolves in water, with evolution of much heat. _Caesium chloride_, CsCl, is obtained by the direct action of chlorine on caesium, or by solution of the hydroxide in hydrochloric acid. It forms small cubes which melt at a red heat and volatilize readily. It deliquesces in moist air. Many double chlorides are known, and may be prepared by mixing solutions of the two components in the requisite proportions. The _bromide_, CsBr, and _iodide_, CsI, resemble the corresponding potassium salts. Many trihaloid salts of caesium are also known, such as CsBr_3, CsClBr_2, CsI_3, CsBrI_2, CsBr_2I, &c. (H.L. Wells and S.L. Penfield, _Zeit. fur anorg. Chem._, 1892, i, p. 85). _Caesium sulphate_, Cs_2SO_4, may be prepared by dissolving the hydroxide or carbonate in sulphuric acid. It crystallizes in short hard prisms, which are readily soluble in water but insoluble in alcohol. It combines with many metallic sulphates (silver, zinc, cobalt, nickel, &c.) to form double sulphates of the type Cs_2SO_4.RSO_4.6H_2O. It also forms a caesium-alum Cs_2SO_4.Al_2(SO_4)_3.24H_2O. _Caesium nitrate_, CsNO_3, is obtained by dissolving the carbonate in nitric acid, and crystallizes in glittering prisms, which melt readily, and on heating evolve oxygen and leave a residue of caesium nitrite. The carbonate, Cs_2CO_3, silicofluoride, Cs_2SiF_6, borate, Cs_2O.3B_2O_3, and the sulphides Cs_2S.4H_2O, Cs_2S_2.H_2O, Cs_2S_3.H_2O, Cs_2S_4 and Cs_2S_6.H_2O, are also known.

Caesium compounds can be readily recognized by the two bright blue lines (of wave length 4555 and 4593) in their flame spectrum, but these are not present in the spark spectrum. The other lines include three in the green, two in the yellow, and two in the orange.

CAESPITOSE (Lat. caespes, a sod), a botanical term for "growing in tufts," like many grasses.

CAESTUS, or CESTUS (from Lat. caedo, strike), a gauntlet or boxing-glove used by the ancient pugilists. Of this there were several varieties, the simplest and least dangerous being the meilichae ([Greek: meilichai]), which consisted of strips of raw hide tied under the palm, leaving the fingers bare. With these the athletes in the palaestrae were wont to practise, reserving for serious contests the more formidable kinds, such as the sphaerae ([Greek: sphairai]), which were sewn with small metal balls covered with leather, and the terrible murmekes ([Greek: murmekes]), sometimes called "limb-breakers" ([Greek: guiotoroi]), which were studded with heavy nails. The straps ([Greek: himantes]) were of different lengths, many reaching to the elbow, in order to protect the forearm when guarding heavy blows (see J.H. Krause, Gymnastik und Agonistik der Hellenen, 1841). The caestus is to be distinguished from cestus (=embroidered, from [Greek: kentein]), an adjective used as a noun in the sense of "girdle," especially the girdle of Aphrodite, which was supposed to have the power of exciting love.

CAESURA (Lat. for "cutting," Gr. [Greek: tome]), in prosody, a rest or pause, usually occurring about the middle of a verse, which is thereby separated into two parts ([Greek: kola], members). In Greek and Latin hexameters the best and most common caesura is the penthemimeral (i.e. after the 5th half-foot):

[Greek: Menin a eide, the a, Pe leia deo Achi leos] Arma vi rumque ca no, Tro jae qui primus ab oris.

Another caesura very common in Homer, but rare in Latin verse, is after the 2nd syllable of the 3rd dactyl:

[Greek: Oio noisi te pasi Di os d' ete leieto boule.]

On the other hand, the hephthemimeral caesura (i.e. after the 7th half-foot) is common in Latin, but rare in Greek:

Formo sam reso nare do ces Ama ryllida silvas.

The "bucolic" caesura, peculiar to Greek (so called because it is chiefly found in writers like Theocritus) occurs after the 4th dactyl:

[Greek: Andra moi ennepe, Mousa, po lutropon, hos mala polla]

In the pentameter verse of the elegiac distich the caesura is always penthemimeral. In the iambic trimeter (consisting of three dipodia or pairs of feet), both in Greek and Latin, the most usual caesura is the penthemimeral; next, the hephthemimeral:

[Greek: O tek na Kad mou tou palai nea trophe] Supplex et o ro reg na per Proser pinae.

[v.04 p.0945] Verses in which neither of these caesuras occurs are considered faulty. On the other hand, secondary or subsidiary caesuras are found in both Greek and Latin; thus, a trithemimeral (after the 3rd half-foot) is combined with the hephthemimeral, which divides the verse into two unequal parts. A caesura is often called masculine when it falls after a long, feminine when it falls after a short syllable.

The best treatise on Greek and Latin metre for general use is L. Mueller, Die Metrik der Griechen und Romer (1885); see also the article VERSE.

CAFFEINE, or THEINE (1.3.7 trimethyl 2.6 dioxypurin), C_8H_{10}N_4O_2.H_2O, a substance found in the leaves and beans of the coffee tree, in tea, in Paraguay tea, and in small quantities in cocoa and in the kola nut. It may be extracted from tea or coffee by boiling with water, the dissolved tannin precipitated by basic lead acetate, the solution filtered, excess of lead precipitated by sulphuretted hydrogen and the filtered liquid then evaporated to crystallization; or, tea is boiled with water, and the whole then evaporated to a syrup, which is mixed with slaked lime, evaporated to dryness on the water-bath and extracted with chloroform (P. Cazeneuve, _Bull. de la soc. chim. de Paris_, 1876-1877, 27, p. 199). Synthetically it may be prepared by the methylation of silver theobromine and silver theophyllin or by boiling heteroxanthine with methyl iodide and potash. E. Fischer and L. Ach (_Berichte_, 1895, 28, p. 3135) have synthesized it from dimethyl alloxan, whilst W. Traube (_Berichte_, 1900, 33, p. 3435) has obtained it from 1.3 diamethyl 4.5 diamino 2.6 dioxypyrimidine. On the constitution of caffeine see PURIN and also E. Fischer (_Annalen_, 1882, 215, p. 253).

Caffeine crystallizes in long silky needles, which are slightly soluble in cold water. It becomes anhydrous at 100 deg.C. and melts at 234 deg. to 235 deg.C. It has a faint bitter taste and gives salts with mineral acids. On oxidation with nitric acid caffeine gives cholesterophane (dimethyl parabanic acid), but if chlorine water be used as the oxidant, then it yields monomethyl urea and dimethyl alloxan (E. Fischer).

CAFFIERI, JACQUES (1678-1755), French worker in metal, the most famous member of a family several of whom distinguished themselves in plastic art, was the fifth son of Philippe Caffieri (1634-1716), a decorative sculptor, who, after serving Pope Alexander VII., entered the service of Louis XIV. in 1660. An elder son of Philippe, Francois Charles (1667-1721), was associated with him. As a fondeur ciseleur, however, the renown of the house centred in Jacques, though it is not always easy to distinguish between his own work and that of his son Philippe (1714-1777). A large proportion of his brilliant achievement as a designer and chaser in bronze and other metals was executed for the crown at Versailles, Fontainebleau, Compiegne, Choisy and La Muette, and the crown, ever in his debt, still owed him money at his death. Jacques and his son Philippe undoubtedly worked together in the "Appartement du Dauphin" at Versailles, and although much of their contribution to the palace has disappeared, the decorations of the marble chimney-piece still remain. They belong to the best type of the Louis XV. style—vigorous and graceful in design, they are executed with splendid skill. It is equally certain that father and son worked together upon the gorgeous bronze case of the famous astronomical clock made by Passement and Danthiau for Louis XV. between 1749 and 1753. The form of the case has been much criticized, and even ridiculed, but the severest critics in that particular have been the readiest to laud the boldness and freedom of the motives, the jewel-like finish of the craftsmanship, the magnificent dexterity of the master-hand. The elder Caffieri was, indeed, the most consummate practitioner of the style rocaille, which he constantly redeemed from its mannered conventionalism by the ease and mastery with which he treated it. From the studio in which he and his son worked side by side came an amazing amount of work, chiefly in the shape of those gilded bronze mounts which in the end became more insistent than the pieces of furniture which they adorned. Little of his achievement was ordinary; an astonishingly large proportion of it is famous. There is in the Wallace collection (Hertford House, London) a commode from the hand of Jacques Caffieri in which the brilliance and spontaneity, the sweeping boldness and elegance of line that mark his style at its best, are seen in a perfection hardly exceeded in any other example. Also at Hertford House is the exceptionally fine lustre which was a wedding present from Louis XV. to Louise Elizabeth of France. After Jacques' death his son Philippe continued to work for the crown, but had many private clients. He made a great cross and six candlesticks for the high altar of Notre Dame, which disappeared in the revolution, but similar work for Bayeux cathedral still exists. A wonderful enamelled toilet set which he executed for the Princess of Asturias has also disappeared. Philippe's style was gradually modified into that which prevailed in the third quarter of the 18th century, since by 1777, when he died, the taste for the magnificent mounts of his early days had passed away. Like his father, he drew large sums from the crown, usually after giving many years' credit, while many other years were needed by his heirs to get in the balance of the royal indebtedness. Philippe's younger brother, Jean Jacques Caffieri (1725-1792), was a sculptor, but was sufficiently adept in the treatment of metals to design the fine rampe d'escalier which still adorns the Palais Royal.

CAFTAN, or KAFTAN (a Turkish word, also in use in Persia), a tunic or under-dress with long hanging sleeves, tied with a girdle at the waist, worn in the East by persons of both sexes. The caftan was worn by the upper and middle classes in Russia till the time of Peter the Great, when it was generally discarded.

CAGLI, a town and (with Pergola) an episcopal see of the Marches, Italy, in the province of Pesaro and Urbino, 18 m. S. of the latter town by rail, and 830 ft. above sea-level. Pop. (1901) of town, 4628; commune, 12,533. The church of S. Domenico contains a good fresco (Madonna and saints) by Giovanni Santi, the father of Raphael. The citadel of the 15th century, constructed by Francesco di Giorgio Martini of Siena, is on the S.E. of the modern town. Cagli occupies the site of an ancient vicus (village) on the Via Flaminia, which seems to have borne the name Cale, 24 m. N. of Helvillum (mod. Sigillo) and 18 m. S.W. of Forum Sempronii (mod. Fossombrone). Below the town to the north is a single arched bridge of the road, the arch having the span of 381/4 ft. (See G. Mochi, Storia di Cagli, Cagli, 1878.) About 5 m. to the N.N.W. of Cagli and 21/2 m. W. of the Via Flaminia at the mod. Acqualagna is the site of an ancient town; the place is now called piano di Valeria, and is scattered with ruins. Inscriptions show that this was a Roman municipium, perhaps Pitinum Mergens (Corp. Inscr. Lat. xi. [Berlin, 1901] p. 876). Three miles north of Acqualagna the Via Flaminia, which is still in use as the modern high-road, traverses the Furlo Pass, a tunnel about 40 yds. long, excavated by Vespasian in A.D. 77, as an inscription at the north end records. There is another tunnel at lower level, which belongs to an earlier date; this seems to have been in use till the construction of the Roman road, which at first ran round the rock on the outside, until Vespasian cut the tunnel. In repairing the modern road just outside the south entrance to the tunnel, a stratum of carbonized corn, beans, &c., and a quantity of burnt wood, stones, tiles, pottery, &c., was found under and above the modern road, for a distance of some 500 yds. This debris must have belonged to the castle of Petra Pertusa, burned by the Lombards in 570 or 571 on their way to Rome. The castle itself is mentioned by Procopius (Bell. Goth. ii. 11, iii. 6, iv. 28, 34). Here also was found the inscription of A.D. 295, relating to the measures taken to suppress brigandage in these parts. (See APENNINES.)

See A. Vernarecci in Notizie degli Scavi, 1886, 411 (cf. ibid. 227); Corp. Inscr. Lat. (Berlin, 1901), Nos. 6106, 6107.

CAGLIARI (anc. Carales), the capital of the island of Sardinia, an archiepiscopal see, and the chief town of the province of Cagliari, which embraces the southern half of the island. It is 270 m. W.S.W. of Naples, and 375 m. south of Genoa by sea. Pop. (1900) of town, 48,098; of commune, 53,057. It is finely situated at the northern extremity of the Gulf of Cagliari, in the centre of the south coast of the island. The medieval town occupies a long narrow hill running N. and S. with precipitous [v.04 p.0946] cliffs on the E. and W. which must have been the ancient acropolis, but the modern town, like the Roman town before it, extends to the slopes of the hill and to the low ground by the sea. On each side of the town are lagoons. That of S. Gilla on the W., which produces fish in abundance, was originally an open bay. That of Molentargius on the E. has large saltpans. The upper town still retains in part its fortifications, including the two great towers at the two extremities, called the Torre dell' Elefante (S.) and the Torre di S. Pancrazio (N.), both erected by the Pisans, the former in 1307, the latter in 1305. The Torre di S. Pancrazio at the highest point (367 ft. above sea-level) commands a magnificent view. Close to it is the archaeological museum, the most important in the island. To the north of it are the modern citadel and the barracks, and beyond, a public promenade. The narrow streets run from north to south for the whole length of the upper town. On the edge of the cliffs on the E. is the cathedral, built in 1257-1312 by the Pisans, and retaining two of the original transept doors. The pulpit of the same period is also fine: it now stands, divided into two, on each side of the entrance, while the lions which supported it are on the balustrade in front of the cathedral (see E. Brunelli in L'Arte, Rome, 1901, 59; D. Scano, ibid. 204). Near the sacristy are also some Gothic chapels of the Aragonese period. The church was, however, remodelled in 1676, and the interior is baroque. Two fine silver candelabra, the tabernacle and the altar front are of the 17th century; and the treasury also contains some good silver work. (See D. Scano in Bolletino d'Arte, February 1907, p. 14; and E. Brunelli in L'Arte, 1907, p. 47.) The crypt contains three ancient sarcophagi. The facade, in the baroque style, was added in 1703. The university, a little farther north, the buildings of which were erected in 1764, has some 240 students. At the south extremity of the hill, on the site of the bastian of south Caterina, a large terrace, the Passeggiata Umberto Primo, has been constructed: it is much in use on summer evenings, and has a splendid view. Below it are covered promenades, and from it steps descend to the lower town, the oldest part of which (the so-called Marina), sloping gradually towards the sea, is probably the nucleus of the Roman municipium, while the quarter of Stampace lies to the west, and beyond it again the suburb of Sant' Avendrace. The northern portion of this, below the castle hill, is the older, while the part near the shore consists mainly of modern buildings of no great interest. To the east of the castle hill and the Marina is the quarter of Villanova, which contains the church of S. Saturnino, a domed church of the 8th century with a choir of the Pisan period. The harbour of Cagliari (along the north side of which runs a promenade called the Via Romo) is a good one, and has a considerable trade, exporting chiefly lead, zinc and other minerals and salt, the total annual value of exports amounting to nearly 11/2 million sterling in value. The Campidano of Cagliari, the plain which begins at the north end of the lagoon of S. Gilla, is very fertile and much cultivated, as is also the district to the east round Quarto S. Elena, a village with 8459 inhabitants (1901). The national costumes are rarely now seen in the neighbourhood of Cagliari, except at certain festivals, especially that of S. Efisio (May 1-4) at Pula (see NORA). The methods of cultivation are primitive: the curious water-wheels, made of brushwood with pots tied on to them, and turned by a blindfolded donkey, may be noted. The ox-carts are often made with solid wheels, for greater strength. Prickly pear (opuntia) hedges are as frequent as in Sicily. Cagliari is considerably exposed to winds in winter, while in summer it is almost African in climate. The aqueduct was constructed in quite recent times, rain-water having previously given the only supply. The main line of railway runs north to Decimomannu (for Iglesias), Oristano, Macomer and Chilivani (for Golfo degli Aranci and Sassari); while another line (narrow-gauge) runs to Mandas (for Sorgono and Tortoli). There is also a tramway to Quarto S. Elena.

In A.D. 485 the whole of Sardinia was taken by the Vandals from Africa; but in 533 it was retaken by Justinian. In 687 Cagliari rose against the East Roman emperors, under Gialetus, one of the citizens, who made himself king of the whole island, his three brothers becoming governors of Torres (in the N.W.), Arborea (in the S.W.) and Gallura (in the N.E. of the island). The Saracens devastated it in the 8th century, but were driven out, and the island returned to the rule of kings, until they fell in the 10th century, their place being taken by four "judges" of the four provinces, Cagliari, Torres, Arborea and Gallura. In the 12th century Musatto, a Saracen, established himself in Cagliari, but was driven out with the help of the Pisans and Genoese. The Pisans soon acquired the sovereignty over the whole island with the exception of Arborea, which continued to be independent. In 1297 Boniface VIII. invested the kings of Aragon with Sardinia, and in 1326 they finally drove the Pisans out of Cagliari, and made it the seat of their government. In 1348 the island was devastated by the plague described by Boccaccio. It was not until 1403 that the kings of Aragon were able to conquer the district of Arborea, which, under the celebrated Eleonora (whose code of laws—the so-called Carta de Logu—was famous), offered a heroic resistance. In 1479 the native princes were deprived of all independence. The island remained in the hands of Spain until the peace of Utrecht (1714), by which it was assigned to Austria. In 1720 it was ceded by the latter, in exchange for Sicily, to the duke of Savoy, who assumed the title of king of Sardinia (Cagliari continuing to be the seat of government), and this remained the title of the house of Savoy until 1861. Cagliari was bombarded by the French fleet in 1793, but Napoleon's attempt to take the island failed.

CAGLIOSTRO, ALESSANDRO, COUNT (1743-1793), Italian alchemist and impostor, was born at Palermo on the 8th of June 1743. Giuseppe Balsamo—for such was the "count's" real name—gave early indications of those talents which afterwards gained for him so wide a notoriety. He received the rudiments of his education at the monastery of Caltagirone in Sicily, but was expelled from it for misconduct and disowned by his relations. He now signalized himself by his dissolute life and the ingenuity with which he contrived to perpetrate forgeries and other crimes without exposing himself to the risk of detection. Having at last got into trouble with the authorities he fled from Sicily, and visited in succession Greece, Egypt, Arabia, Persia, Rhodes—where he took lessons in alchemy and the cognate sciences from the Greek Althotas—and Malta. There he presented himself to the grand master of the Maltese order as Count Cagliostro, and curried favour with him as a fellow alchemist, for the grand master's tastes lay in the same direction. From him he obtained introductions to the great houses of Rome and Naples, whither he now hastened. At Rome he married a beautiful but unprincipled woman, Lorenza Feliciani, with whom he travelled, under different names, through many parts of Europe. It is unnecessary to recount the various infamous means which he employed to pay his expenses during these journeys. He visited London and Paris in 1771, selling love-philtres, elixirs of youth, mixtures for making ugly women beautiful, alchemistic powders, &c., and deriving large profits from his trade. After further travels on the continent he returned to London, where he posed as the founder of a new system of freemasonry, and was well received in the best society, being adored by the ladies. He went to Germany and Holland once more, and to Russia, Poland, and then again to Paris, where, in 1785, he was implicated in the affair of the Diamond Necklace (q.v.); and although Cagliostro escaped conviction by the matchless impudence of his defence, he was imprisoned for other reasons in the Bastille. On his liberation he visited England once more, where he succeeded well at first; but was ultimately outwitted by some English lawyers, and confined for a while in the Fleet prison. Leaving England, he travelled through Europe as far as Rome, where he was arrested in 1789. He was tried and condemned to death for being a heretic, but the sentence was commuted to perpetual imprisonment, while his wife was immured in a convent. He died in the fortress prison of San Leo in 1795.

CAGNIARD DE LA TOUR, CHARLES (1777-1859), French engineer and physicist, was born in Paris on the 31st of March 1777, and after attending the Ecole Polytechnique became one of the ingenieurs geographiques. He was made a baron in 1818, and died in Paris on the 5th of July 1859. He was the author of numerous inventions, including the cagniardelle, a blowing machine, which consists essentially of an Archimedean screw set obliquely in a tank of water in such a way that its lower end is completely and its upper end partially immersed, and operated by being rotated in the opposite direction to that required for raising water. In acoustics he invented, about 1819, the improved siren which is known by his name, using it for ascertaining the number of vibrations corresponding to a sound of any particular pitch, and he also made experiments on the mechanism of voice-production. In course of an investigation in 1822-1823 on the effects of heat and pressure on certain liquids he found that for each there was a certain temperature above which it refused to remain liquid but passed into the gaseous state, no matter what the amount of pressure to which it was subjected, and in the case of water he determined this critical temperature, with a remarkable approach to accuracy, to be 362 deg.C. He also studied the nature of yeast and the influence of extreme cold upon its life.

CAGNOLA, LUIGI, MARCHESE (1762-1833), Italian architect, was born on the 9th of June 1762 in Milan. He was sent at the age of fourteen to the Clementine College at Rome, and afterwards studied at the university of Pavia. He was intended for the legal profession, but his passion for architecture was too strong, and after holding some government posts at Milan, he entered as a competitor for the construction of the Porta Orientale. His designs were commended, but were not selected on account of the expense their adoption would have involved. From that time Cagnola devoted himself entirely to architecture. After the death of his father he spent two years in Verona and Venice, studying the architectural structures of these cities. In 1806 he was called upon to erect a triumphal arch for the marriage of Eugene Beauharnais with the princess of Bavaria. The arch was of wood, but was of such beauty that it was resolved to carry it out in marble. The result was the magnificent Arco della Pace in Milan, surpassed in dimensions only by the Arc de l'Etoile at Paris. Among other works executed by Cagnola are the Porta di Marengo at Milan, the campanile at Urgnano, and the chapel of Santa Marcellina in Milan. He died on the 14th of August 1833, five years before the completion of the Arco del Sempione, which he designed for his native city.

CAGOTS, a people found in the Basque provinces, Bearn, Gascony and Brittany. The earliest mention of them is in 1288, when they appear to have been called Christiens or Christianos. In the 16th century they had many names, Cagots, Gahets, Gafets in France; Agotes, Gafos in Spain; and Cacons, Cahets, Caqueux and Caquins in Brittany. During the middle ages they were popularly looked upon as cretins, lepers, heretics and even as cannibals. They were shunned and hated; were allotted separate quarters in towns, called cagoteries, and lived in wretched huts in the country distinct from the villages. Excluded from all political and social rights, they were only allowed to enter a church by a special door, and during the service a rail separated them from the other worshippers. Either they were altogether forbidden to partake of the sacrament, or the holy wafer was handed to them on the end of a stick, while a receptacle for holy water was reserved for their exclusive use. They were compelled to wear a distinctive dress, to which, in some places, was attached the foot of a goose or duck (whence they were sometimes called Canards). And so pestilential was their touch considered that it was a crime for them to walk the common road barefooted. The only trades allowed them were those of butcher and carpenter, and their ordinary occupation was wood-cutting. Their language is merely a corrupt form of that spoken around them; but a Teutonic origin seems to be indicated by their fair complexions and blue eyes. Their crania have a normal development; their cheek-bones are high; their noses prominent, with large nostrils; their lips straight; and they are marked by the absence of the auricular lobules.

The origin of the Cagots is undecided. Littre defines them as "a people of the Pyrenees affected with a kind of cretinism." It has been suggested that they were descendants of the Visigoths, and Michael derives the name from caas (dog) and Goth. But opposed to this etymology is the fact that the word cagot is first found in the for of Bearn not earlier than 1551. Marca, in his Histoire de Bearn, holds that the word signifies "hunters of the Goths," and that the Cagots are descendants of the Saracens. Others made them descendants of the Albigenses. The old MSS. call them Chretiens or Chrestiaas, and from this it has been argued that they were Visigoths who originally lived as Christians among the Gascon pagans. A far more probable explanation of their name "Chretiens" is to be found in the fact that in medieval times all lepers were known as pauperes Christi, and that, Goths or not, these Cagots were affected in the middle ages with a particular form of leprosy or a condition resembling it. Thus would arise the confusion between Christians and Cretins. To-day their descendants are not more subject to goitre and cretinism than those dwelling around them, and are recognized by tradition and not by features or physical degeneracy. It was not until the French Revolution that any steps were taken to ameliorate their lot, but to-day they no longer form a class, but have been practically lost sight of in the general peasantry.

CAHER (or CAHIR), a market-town of Co. Tipperary, Ireland, in the south parliamentary division, beautifully situated on the river Suir at the foot of the Galtee Mountains. Pop. (1901) 2058. It stands midway between Clonmel and Tipperary town on the Waterford and Limerick line of the Great Southern and Western railway, 124 m. S.W. from Dublin. It is the centre of a rich agricultural district, and there is some industry in flour-milling. Its name (cathair, stone fortress) implies a high antiquity and the site of the castle, picturesquely placed on an island in the river, was occupied from very early times. Here was a fortress-palace of Munster, originally called Dun-iasgach, the suffix signifying "abounding in fish." The present castle dates from 1142, being built by O'Connor, lord of Thomond, and is well restored. It was besieged during the wars of 1599 and 1647, and by Cromwell. Among the fine environs of the town the demesne of Caher Park is especially noteworthy. The Mitchelstown stalactite caverns, 10 m. S.W., and the finely-placed Norman castle of Ardfinnan, on a precipitous crag 6 m. down the Suir, are other neighbouring features of interest, while the Galtee Mountains, reaching in Galtymore a height of 3015 ft., command admirable prospects.

CAHITA, a group of North American Indians, mainly of the Mayo and Yaqui tribes, found chiefly in Mexico, belonging to the Piman family, and numbering some 40,000.

CAHOKIA, the name of a North American Indian tribe of the Illinois confederacy, and of their mission station, near St Louis. The "Cahokia mound" there (a model of which is in the Peabody Museum, Cambridge, Mass.) is interesting as the largest pre-historic earth-work in America.

CAHORS, a city of south-western France, capital of the department of Lot, 70 m. N. of Toulouse, on the railway between that city and Limoges. Pop. (1906) 10,047. Cahors stands on the right bank of the river Lot, occupying a rocky peninsula formed by a bend in the stream. It is divided into two portions [v.04 p.0948] by the Boulevard Gambetta, which runs from the Pont Louis Philippe on the south to within a short distance of the fortified wall of the 14th and 15th centuries enclosing the town on the north. To the east lies the old town, with its dark narrow streets and closely-packed houses; west of the Boulevard a newer quarter, with spacious squares and promenades, stretches to the bank of the river. Cahors communicates with the opposite shore by three bridges. One of these, the Pont Valentre to the west of the town, is the finest fortified bridge of the middle ages in France. It is a structure of the early 14th century, restored in the 19th century, and is defended at either end by high machicolated towers, another tower, less elaborate, surmounting the centre pier. The east bridge, the Pont Neuf, also dates from the 14th century. The cathedral of St Etienne stands in the heart of the old town. It dates from the 12th century, but was entirely restored in the 13th century. Its exterior, for the most part severe in appearance, is relieved by some fine sculpture, that of the north portal being especially remarkable. The nave, which is without aisles, is surmounted by two cupolas; its interior is whitewashed and plain in appearance, while the choir is decorated with medieval paintings. Adjoining the church to the south-east there are remains of a cloister built from 1494 to 1509. St Urcisse, the chief of the other ecclesiastical buildings, stands near the cathedral. Dating from the 12th and 13th centuries, it preserves Romanesque capitals recarved in the 14th century. The principal of the civil buildings is the palace of Pope John XXII., built at the beginning of the 14th century; a massive square tower is still standing, but the rest is in ruins. The residence of the seneschals of Quercy, a building of the 14th to the 17th centuries, known as the Logis du Roi, also remains. The chief of the old houses, of which there are many in Cahors, is one of the 15th century, known as the Maison d'Henri IV. Most of the state buildings are modern, with the exception of the prefecture which occupies the old episcopal palace, and the old convent and the Jesuit college in which the Lycee Gambetta is established. The Porte de Diane is a large archway of the Roman period, probably the entrance to the baths. Of the commemorative monuments, the finest is that erected in the Place d'Armes to Gambetta, who was a native of the town. There is also a statue of the poet Clement Marot, born at Cahors in 1496. Cahors is the seat of a bishopric, a prefect and a court of assizes. It has tribunals of first instance and of commerce, a chamber of commerce and a branch of the Bank of France. There are also training colleges, a lycee, a communal college for girls, an ecclesiastical seminary, a library, museum and hospital. The manufacture of farm implements, tanning, wool-spinning, metal-founding, distilling and the preparation of pate de foie gras and other delicacies are carried on. Wine, nuts, oil of nuts, tobacco, truffles and plums are leading articles of commerce.

History.—Before the Roman conquest, Cahors, which grew up near the sacred fountain of Divona (now known as the Fontaine des Chartreux), was the capital of the Cadurci. Under the Romans it enjoyed a prosperity partly due to its manufacture of cloth and of mattresses, which were exported even to Rome. The first bishop of Cahors, St Genulfus, appears to have lived in the 3rd century. In the middle ages the town was the capital of Quercy, and its territory until after the Albigensian Crusade was a fief of the counts of Toulouse. The seigniorial rights, including that of coining money, belonged to the bishops. In the 13th century Cahors was a financial centre of much importance owing to its colony of Lombard bankers, and the name cahorsin consequently came to signify "banker" or "usurer." At the beginning of the century a commune was organized in the town. Its constant opposition to the bishops drove them, in 1316, to come to an arrangement with the French king, by which the administration of the town was placed almost entirely in the hands of royal officers, king and bishop being co-seigneurs. This arrangement survived till the Revolution. In 1331 Pope John XXII., a native of Cahors, founded there a university, which afterwards numbered Jacques Cujas among its teachers and Francois Fenelon among its students. It flourished till 1751, when it was united to its rival the university of Toulouse. During the Hundred Years' War, Cahors, like the rest of Quercy, consistently resisted the English occupation, from which it was relieved in 1428. In the 16th century it belonged to the viscounts of Bearn, but remained Catholic and rose against Henry of Navarre who took it by assault in 1580. On his accession Henry IV. punished the town by depriving it of its privileges as a wine-market; the loss of these was the chief cause of its decline.

CAIATIA (mod. Caiazzo), an ancient city of Campania, on the right bank of the Volturnus, 11 m. N.E. of Capua, on the road between it and Telesia. It was already in the hands of the Romans in 306 B.C., and since in the 3rd century B.C. it issued copper coins with a Latin legend it must have had the civitas sine suffragio. In the Social War it rebelled from Rome, and its territory was added to that of Capua by Sulla. In the imperial period, however, we find it once more a municipium. Caiatia has remains of Cyclopean walls, and under the Piazza del Mercato is a large Roman cistern, which still provides a good water supply. The episcopal see was founded in A.D. 966. The place is frequently confused with Calatia (q.v.).

CAIETAE PORTUS (mod. Gaeta), an ancient harbour of Latium adiectum, Italy, in the territory of Formiae, from which it is 5 m. S.W. The name (originally [Greek: Aiete]) is generally derived from the nurse of Aeneas. The harbour, owing to its fine anchorage, was much in use, but the place was never a separate town, but always dependent on Formiae. Livy mentions a temple of Apollo. The coast of the Gulf not only between Caietae Portus and Formiae, but E. of the latter also, as far as the modern Monte Scauri, was a favourite summer resort (see FORMIA). Cicero may have had villas both at Portus Caietae and at Formiae[1] proper, and the emperors certainly possessed property at both places. After the destruction of Formiae in A.D. 847 it became one of the most important seaports of central Italy (see GAETA). In the town are scanty remains of an amphitheatre and theatre: near the church of La Trinita, higher up, are remains of a large reservoir. There are also traces of an aqueduct. The promontory (548 ft.) is crowned by the tomb of Munatius Plancus, founder of Lugudunum (mod. Lyons), who died after 22 B.C. It is a circular structure of blocks of travertine 160 ft. high and 180 ft. in diameter. Further inland is the so-called tomb of L. Atratinus, about 100 ft. in diameter. Caietae Portus was no doubt connected with the Via Appia (which passed through Formiae) by a deverticulum. There seems also to have been a road running W.N.W. along the precipitous coast to Speluncae (mod. Sperlonga).

See E. Gesualdo Osservazioni critiche sopra la storia della Via Appia di Pratilli p. 7 (Naples, 1754).

[1] The two places are sufficiently close for the one villa to have borne both names; but Mommsen (Corp. Inscrip. Lat. x., Berlin, 1883, p. 603) prefers to differentiate them.

CAILLIE (or CAILLE), RENE AUGUSTE (1799-1838), French explorer, was born at Mauze, Poitou, in 1799, the son of a baker. The reading of Robinson Crusoe kindled in him a love of travel and adventure, and at the age of sixteen he made a voyage to Senegal whence he went to Guadeloupe. Returning to Senegal in 1818 he made a journey to Bondu to carry supplies to a British expedition then in that country. Ill with fever he was obliged to go back to France, but in 1824 was again in Senegal with the fixed idea of penetrating to Timbuktu. He spent eight months with the Brakna "Moors" living north of Senegal river, learning Arabic and being taught, as a convert, the laws and customs of Islam. He laid his project of reaching Timbuktu before the governor of Senegal, but receiving no encouragement went to Sierra Leone where the British authorities made him superintendent of an indigo plantation. Having saved L80 he joined a Mandingo caravan going inland. He was dressed as a Mussulman, and gave out that he was an Arab from Egypt who had been carried off by the French to Senegal and was desirous of regaining his own country. Starting from Kakundi near Boke on the Rio Nunez on 19th of April 1827, he travelled east along the hills of Futa Jallon, passing the head streams of the Senegal and crossing the Upper Niger at Kurussa. Still going east he came to the Kong highlands, where at a place called Time he was detained five months by illness. Resuming his journey [v.04 p.0949] in January 1828 he went north-east and gained the city of Jenne, whence he continued his journey to Timbuktu by water. After spending a fortnight (20th April-4th May) in Timbuktu he joined a caravan crossing the Sahara to Morocco, reaching Fez on the 12th of August. From Tangier he returned to France. He had been preceded at Timbuktu by a British officer, Major Gordon Laing, but Laing had been murdered (1826) on leaving the city and Caillie was the first to accomplish the journey in safety. He was awarded the prize of L400 offered by the Geographical Society of Paris to the first traveller who should gain exact information of Timbuktu, to be compared with that given by Mungo Park. He also received the order of the Legion of Honour, a pension, and other distinctions, and it was at the public expense that his Journal d'un voyage a Temboctou et a Jenne dans l'Afrique Centrale, etc. (edited by E.F. Jomard) was published in three volumes in 1830. Caillie died at Badere in 1838 of a malady contracted during his African travels. For the greater part of his life he spelt his name Caillie, afterwards omitting the second "i."

See Dr Robert Brown's The Story of Africa, vol. i. chap. xii. (London, 1892); Goepp and Cordier, Les Grands Hommes de France, voyageurs: Rene Caille (Paris, 1885); E.F. Jomard, Notice historique sur la vie et les voyages de R. Caillie (Paris, 1839). An English version of Caillie's Journal was published in London in 1830 in two volumes under the title of Travels through Central Africa to Timbuctoo, &c.

CAIN, in the Bible, the eldest son of Adam and Eve (Gen. iv.), was a tiller of the ground, whilst his younger brother, Abel, was a keeper of sheep. Enraged because the Lord accepted Abel's offering, and rejected his own, he slew his brother in the field (see ABEL). For this a curse was pronounced upon him, and he was condemned to be a "fugitive and a wanderer" on the earth, a mark being set upon him "lest any finding him should kill him." He took up his abode in the land of Nod ("wandering") on the east of Eden, where he built a city, which he named after his son Enoch. The narrative presents a number of difficulties, which early commentators sought to solve with more ingenuity than success. But when it is granted that the ancient Hebrews, like other primitive peoples, had their own mythical and traditional figures, the story of Cain becomes less obscure. The mark set upon Cain is usually regarded as some tribal mark or sign analogous to the cattle marks of Bedouin and the related usages in Europe. Such marks had often a religious significance, and denoted that the bearer was a follower of a particular deity. The suggestion has been made that the name Cain is the eponym of the Kenites, and although this clan has a good name almost everywhere in the Old Testament, yet in Num. xxiv. 22 its destruction is foretold, and the Amalekites, of whom they formed a division, are consistently represented as the inveterate enemies of Yahweh and of his people Israel. The story of Cain and Abel, which appears to represent the nomad life as a curse, may be an attempt to explain the origin of an existence which in the eyes of the settled agriculturist was one of continual restlessness, whilst at the same time it endeavours to find a reason for the institution of blood-revenge on the theory that at some remote age a man (or tribe) had killed his brother (or brother tribe). Cain's subsequent founding of a city finds a parallel in the legend of the origin of Rome through the swarms of outlaws and broken men of all kinds whom Romulus attracted thither. The list of Cain's descendants reflects the old view of the beginnings of civilization; it is thrown into the form of a genealogy and is parallel to Gen. v. (see GENESIS). It finds its analogy in the Phoenician account of the origin of different inventions which Eusebius (Praep. Evang. i. 10) quotes from Philo of Byblus (Gebal), and probably both go back to a common Babylonian origin.

On this question, see Driver, Genesis (Westminster Comm., London, 1904), p. 80 seq.; A. Jeremias, Alte Test. im Lichte d. Alten Orients (Leipzig, 1906), pp. 220 seq.; also ENOCH, LAMECH. On the story of Cain, see especially Stade, Akademische Reden, pp. 229-273; Ed. Meyer, Israeliten, pp. 395 sqq.; A.R. Gordon, Early Trad. Genesis (Index). Literary criticism (see Cheyne, Encycl. Bib. col. 620-628, and 4411-4417) has made it extremely probable that Cain the nomad and outlaw (Gen. iv. 1-16) was originally distinct from Cain the city-builder (vv. 17 sqq.). The latter was perhaps regarded as a "smith," cp. v. 22 where Tubal-cain is the "father" of those who work in bronze (or copper). That the Kenites, too, were a race of metal-workers is quite uncertain, although even at the present day the smiths in Arabia form a distinct nomadic class. Whatever be the meaning of the name, the words put into Eve's mouth (v. 1) probably are not an etymology, but an assonance (Driver). It is noteworthy that Kenan, son of Enosh ("man," Gen. v. 9), appears in Sabaean inscriptions of South Arabia as the name of a tribal-god.

A Gnostic sect of the 2nd century was known by the name of Cainites. They are first mentioned by Irenaeus, who connects them with the Valentinians. They believed that Cain derived his existence from the superior power, and Abel from the inferior power, and that in this respect he was the first of a line which included Esau, Korah, the Sodomites and Judas Iscariot.

CAINE, THOMAS HENRY HALL (1853- ), British novelist and dramatist, was born of mixed Manx and Cumberland parentage at Runcorn, Cheshire, on the 14th of May 1853. He was educated with a view to becoming an architect, but turned to journalism, becoming a leader-writer on the Liverpool Mercury. He came up to London at the suggestion of D.G. Rossetti, with whom he had had some correspondence, and lived with the poet for some time before his death. He published a volume of Recollections of Rossetti (1882), and also some critical work; but in 1885 he began an extremely successful career as a novelist of a melodramatic type with The Shadow of a Crime, followed by The Son of Hagar (1886), The Deemster (1887), The Bondman (1890), The Scapegoat (1891), The Manxman (1894), The Christian (1897), The Eternal City (1901), and The Prodigal Son (1904). His writings on Manx subjects were acknowledged by his election in 1901 to represent Ramsey in the House of Keys. The Deemster, The Manxman and The Christian had already been produced in dramatic form, when The Eternal City was staged with magnificent accessories by Mr Beerbohm Tree in 1902, and in 1905 The Prodigal Son had a successful run at Drury Lane.

See C.F. Kenyon, Hall Caine; The Man and the Novelist (1901); and the novelist's autobiography, My Story (1908).

CA'ING WHALE (Globicephalus melas), a large representative of the dolphin tribe frequenting the coasts of Europe, the Atlantic coast of North America, the Cape and New Zealand. From its nearly uniform black colour it is also called the "black-fish." Its maximum length is about 20 ft. These cetaceans are gregarious and inoffensive in disposition and feed chiefly on cuttle-fish. Their sociable character constantly leads to their destruction, as when attacked they instinctively rush together, and blindly follow the leaders of the herd, whence the names pilot-whale and ca'ing (or driving) whale. Many hundreds at a time are thus frequently driven ashore and killed, when a herd enters one of the bays or fiords of the Faeroe Islands or north of Scotland. The ca'ing whale of the North Pacific has been distinguished as G. scammoni, while one from the Atlantic coast, south of New Jersey, and another from the bay of Bengal, are possibly also distinct. (See CETACEA.)

CAINOZOIC (from the Gr. [Greek: kainos], recent, [Greek: zoe], life), also written Cenozoic (American), Kainozoisch, Caenozoisch (German), Cenozoaire (Renevier), in geology, the name given to the youngest of the three great eras of geological time, the other two being the Mesozoic and Palaeozoic eras. Some authors have employed the term "Neozoic" (Neozoisch) with the same significance, others have restricted its application to the Tertiary epoch (Neozoique, De Lapparent). The "Neogene" of Hoernes (1853) included the Miocene and Pliocene periods; Renevier subsequently modified its form to Neogenique. The remaining Tertiary periods were classed as Paleogaen by Naumaun in 1866. The word "Neocene" has been used in place of Neozoic, but its employment is open to objection.

Some confusion has been introduced by the use of the term Cainozoic to include, on the one hand, the Tertiary period alone, and on the other hand, to make it include both the Tertiary and the post-Tertiary or Quaternary epochs; and in order that it may bear a relationship to the concepts of time and faunal development similar to those indicated by the terms Mesozoic and Palaeozoic it is advisable to restrict its use to the latter alternative. Thus the Cainozoic era would embrace all the geological periods from Eocene to Recent. (See TERTIARY and PLEISTOCENE.)

[v.04 p.0950] CAIQUE (from Turk. Kaik), a light skiff or rowing-boat used by the Turks, having from one to twelve rowers; also a Levantine sailing vessel of considerable size.

CA IRA, a song of the French Revolution, with the refrain:—

"Ah! ca ira, ca ira, ca ira! Les aristocrates a la lanterne."

The words, written by one Ladre, a street singer, were put to an older tune, called "Le Carillon National," and the song rivalled the "Carmagnole" (q.v.) during the Terror. It was forbidden by the Directory.

CAIRD, EDWARD (1835-1908), British philosopher and theologian, brother of John Caird (q.v.), was born at Greenock on the 22nd of March 1835, and educated at Glasgow University and Balliol College, Oxford. He took a first class in moderations in 1862 and in Literae humaniores in 1863, and was Pusey and Ellerton scholar in 1861. From 1864 to 1866 he was fellow and tutor of Merton College. In 1866 he became professor of moral philosophy in the university of Glasgow, and in 1893 succeeded Benjamin Jowett as master of Balliol. With Thomas Hill Green he founded in England a school of orthodox neo-Hegelianism (see HEGEL, ad fin.), and through his pupils he exerted a far-reaching influence on English philosophy and theology. Owing to failing health he gave up his lectures in 1904, and in May 1906 resigned his mastership, in which he was succeeded by James Leigh Strachan-Davidson, who had previously for some time, as senior tutor and fellow, borne the chief burden of college administration. Dr Caird received the honorary degree of D.C.L. in 1892; he was made a corresponding member of the French Academy of Moral and Political Science and a fellow of the British Academy. His publications include Philosophy of Kant (1878); Critical Philosophy of Kant (1889); Religion and Social Philosophy of Comte (1885); Essays on Literature and Philosophy (1892); Evolution of Religion (Gifford Lectures, 1891-1892); Evolution of Theology in the Greek Philosophers (1904); and he is represented in this encyclopaedia by the article on CARTESIANISM. He died on the 1st of November 1908.

CAIRD, JOHN (1820-1898), Scottish divine and philosopher, was born at Greenock on the 15th of December 1820. In his sixteenth year he entered the office of his father, who was partner and manager of a firm of engineers. Two years later, however, he obtained leave to continue his studies at Glasgow University. After a year of academic life he tried business again, but in 1840 he gave it up finally and returned to college. In 1845 he entered the ministry of the Church of Scotland, and after holding several livings accepted the chair of divinity at Glasgow in 1862. During these years he won a foremost place among the preachers of Scotland. In theology he was a Broad Churchman, seeking always to emphasize the permanent elements in religion, and ignoring technicalities. In 1873 he was appointed vice-chancellor and principal of Glasgow University. He delivered the Gifford Lectures in 1892-1893 and in 1895-1896. His Introduction to the Philosophy of Religion (1880) is an attempt to show the essential rationality of religion. It is idealistic in character, being in fact a reproduction of Hegelian teaching in clear and melodious language. His argument for the Being of God is based on the hypothesis that thought—not individual but universal—is the reality of all things, the existence of this Infinite Thought being demonstrated by the limitations of finite thought. Again his Gifford Lectures are devoted to the proof of the truth of Christianity on grounds of right reason alone. Caird wrote also an excellent study of Spinoza, in which he showed the latent Hegelianism of the great Jewish philosopher. He died on the 30th of July 1898.

CAIRN (in Gaelic and Welsh, Carn), a heap of stones piled up in a conical form. In modern times cairns are often erected as landmarks. In ancient times they were erected as sepulchral monuments. The Duan Eireanach, an ancient Irish poem, describes the erection of a family cairn; and the Senchus Mor, a collection of ancient Irish laws, prescribes a fine of three three-year-old heifers for "not erecting the tomb of thy chief." Meetings of the tribes were held at them, and the inauguration of a new chief took place on the cairn of one of his predecessors. It is mentioned in the Annals of the Four Masters that, in 1225, the O'Connor was inaugurated on the cairn of Fraech, the son of Fiodhach of the red hair. In medieval times cairns are often referred to as boundary marks, though probably not originally raised for that purpose. In a charter by King Alexander II. (1221), granting the lands of Burgyn to the monks of Kinloss, the boundary is described as passing "from the great oak in Malevin as far as the Rune Pictorum," which is explained as "the Carne of the Pecht's fieldis." In Highland districts small cairns used to be erected, even in recent times, at places where the coffin of a distinguished person was "rested" on its way to the churchyard. Memorial cairns are still occasionally erected, as, for instance, the cairn raised in memory of the prince consort at Balmoral, and "Maule's Cairn," in Glenesk, erected by the earl of Dalhousie in 1866, in memory of himself and certain friends specified by name in the inscription placed upon it. (See BARROW.)

CAIRNES, JOHN ELLIOTT (1823-1875), British political economist, was born at Castle Bellingham, Ireland, in 1823. After leaving school he spent some years in the counting-house of his father, a brewer. His tastes, however, lay altogether in the direction of study, and he was permitted to enter Trinity College, Dublin, where he took the degree of B.A. in 1848, and six years later that of M.A. After passing through the curriculum of arts he engaged in the study of law and was called to the Irish bar. But he felt no very strong inclination for the legal profession, and during some years he occupied himself to a large extent with contributions to the daily press, treating of the social and economical questions that affected Ireland. He devoted most attention to political economy, which he studied with great thoroughness and care. While residing in Dublin he made the acquaintance of Archbishop Whately, who conceived a very high respect for his character and abilities. In 1856 a vacancy occurred in the chair of political economy at Dublin founded by Whately, and Cairnes received the appointment. In accordance with the regulations of the foundation, the lectures of his first year's course were published. The book appeared in 1857 with the title Character and Logical Method of Political Economy. It follows up and expands J.S. Mill's treatment in the Essays on some Unsettled Questions in Political Economy, and forms an admirable introduction to the study of economics as a science. In it the author's peculiar powers of thought and expression are displayed to the best advantage. Logical exactness, precision of language, and firm grasp of the true nature of economic facts, are the qualities characteristic of this as of all his other works. If the book had done nothing more, it would still have conferred inestimable benefit on political economists by its clear exposition of the true nature and meaning of the ambiguous term "law." To the view of the province and method of political economy expounded in this early work the author always remained true, and several of his later essays, such as those on Political Economy and Land, Political Economy and Laissez-Faire, are but reiterations of the same doctrine. His next contribution to economical science was a series of articles on the gold question, published partly in Fraser's Magazine, in which the probable consequences of the increased supply of gold attendant on the Australian and Californian gold discoveries were analysed with great skill and ability. And a critical article on M. Chevalier's work On the Probable Fall in the Value of Gold appeared in the Edinburgh Review for July 1860.

In 1861 Cairnes was appointed to the professorship of political economy and jurisprudence in Queen's College, Galway, and in the following year he published his admirable work The Slave Power, one of the finest specimens of applied economical philosophy. The inherent disadvantages of the employment of slave labour were exposed with great fulness and ability, and the conclusions arrived at have taken their place among the recognized doctrines of political economy. The opinions expressed by Cairnes as to the probable issue of the war in America were largely verified by the actual course of events, and the appearance of the book had a marked influence on the attitude taken by serious political thinkers in England towards the southern states.

[v.04 p.0951]

During the remainder of his residence at Galway Professor Cairnes published nothing beyond some fragments and pamphlets mainly upon Irish questions. The most valuable of these papers are the series devoted to the consideration of university education. His health, at no time very good, was still further weakened in 1865 by a fall from his horse. He was ever afterwards incapacitated from active exertion and was constantly liable to have his work interfered with by attacks of illness. In 1866 he was appointed professor of political economy in University College, London. He was compelled to spend the session 1868-1869 in Italy but on his return continued to lecture till 1872. During his last session he conducted a mixed class, ladies being admitted to his lectures. His health soon rendered it impossible for him to discharge his public duties; he resigned his post in 1872, and retired with the honorary title of emeritus professor of political economy. In 1873 his own university conferred on him the degree of LL.D. He died at Blackheath, near London, on the 8th of July 1875.

The last years of his life were spent in the collection and publication of some scattered papers contributed to various reviews and magazines, and in the preparation of his most extensive and important work. The Political Essays, published in 1873, comprise all his papers relating to Ireland and its university system, together with some other articles of a somewhat similar nature. The Essays in Political Economy, Theoretical and Applied, which appeared in the same year, contain the essays towards a solution of the gold question, brought up to date and tested by comparison with statistics of prices. Among the other articles in the volume the more important are the criticisms on Bastiat and Comte, and the essays on Political Economy and Land, and on Political Economy and Laissez-Faire, which have been referred to above. In 1874 appeared his largest work, Some Leading Principles of Political Economy, newly Expounded, which is beyond doubt a worthy successor to the great treatises of Smith, Malthus, Ricardo and Mill. It does not expound a completed system of political economy; many important doctrines are left untouched; and in general the treatment of problems is not such as would be suited for a systematic manual. The work is essentially a commentary on some of the principal doctrines of the English school of economists, such as value, cost of production, wages, labour and capital, and international values, and is replete with keen criticism and lucid illustration. While in fundamental harmony with Mill, especially as regards the general conception of the science, Cairnes differs from him to a greater or less extent on nearly all the cardinal doctrines, subjects his opinions to a searching examination, and generally succeeds in giving to the truth that is common to both a firmer basis and a more precise statement. The last labour to which he devoted himself was a republication of his first work on the Logical Method of Political Economy.

Taken as a whole the works of Cairnes formed the most important contribution to economical science made by the English school since the publication of J.S. Mill's Principles. It is not possible to indicate more than generally the special advances in economic doctrine effected by him, but the following points may be noted as establishing for him a claim to a place beside Ricardo and Mill: (1) His exposition of the province and method of political economy. He never suffers it to be forgotten that political economy is a science, and consequently that its results are entirely neutral with respect to social facts or systems. It has simply to trace the necessary connexions among the phenomena of wealth and dictates no rules for practice. Further, he is distinctly opposed both to those who would treat political economy as an integral part of social philosophy, and to those who have attempted to express economic facts in quantitative formulae and to make economy a branch of applied mathematics. According to him political economy is a mixed science, its field being partly mental, partly physical. It may be called a positive science, because its premises are facts, but it is hypothetical in so far as the laws it lays down are only approximately true, i.e. are only valid in the absence of counteracting agencies. From this view of the nature of the science, it follows at once that the method to be pursued must be that called by Mill the physical or concrete deductive, which starts from certain known causes, investigates their consequences and verifies or tests the result by comparison with facts of experience. It may, perhaps, be thought that Cairnes gives too little attention to the effects of the organism of society on economic facts, and that he is disposed to overlook what Bagehot called the postulates of political economy. (2) His analysis of cost of production in its relation to value. According to Mill, the universal elements in cost of production are the wages of labour and the profits of capital. To this theory Cairnes objects that wages, being remuneration, can in no sense be considered as cost, and could only have come to be regarded as cost in consequence of the whole problem being treated from the point of view of the capitalist, to whom, no doubt, the wages paid represent cost. The real elements of cost of production he looks upon as labour, abstinence and risk, the second of these falling mainly, though not necessarily, upon the capitalist. In this analysis he to a considerable extent follows and improves upon Senior, who had previously defined cost of production as the sum of the labour and abstinence necessary to production. (3) His exposition of the natural or social limit to free competition, and of its bearing on the theory of value. He points out that in any organized society there can hardly be the ready transference of capital from one employment to another, which is the indispensable condition of free competition; while class distinctions render it impossible for labour to transfer itself readily to new occupations. Society may thus be regarded as consisting of a series of non-competing industrial groups, with free competition among the members of any one group or class. Now the only condition under which cost of production will regulate value is perfect competition. It follows that the normal value of commodities—the value which gives to the producers the average and usual remuneration—will depend upon cost of production only when the exchange is confined to the members of one class, among whom there is free competition. In exchange between classes or non-competing industrial groups, the normal value is simply a case of international value, and depends upon reciprocal demand, that is to say, is such as will satisfy the equation of demand. This theory is a substantial contribution to economical science and throws great light upon the general problem of value. At the same time, it may be thought that Cairnes overlooked a point brought forward prominently by Senior, who also had called attention to the bearing of competition on the relation between cost of production and value. The cost to the producer fixes the limit below which the price cannot fall without the supply being affected; but it is the desire of the consumer—i.e. what he is willing to give up rather than be compelled to produce the commodity for himself—that fixes the maximum value of the article. To treat the whole problem of natural or normal value from the point of view of the producer is to give but a one-sided theory of the facts. (4) His defence of the wages fund doctrine. This doctrine, expounded by Mill in his Principles, had been relinquished by him, but Cairnes still undertook to defend it. He certainly succeeded in removing from the theory much that had tended to obscure its real meaning and in placing it in its very best aspect. He also showed the sense in which, when treating the problem of wages, we must refer to some fund devoted to the payment of wages, and pointed out the conditions under which the wages fund may increase or decrease. It may be added that his Leading Principles contain admirable discussions on trade unions and protection, together with a clear analysis of the difficult theory of international trade and value, in which there is much that is both novel and valuable. The Logical Method contains about the best exposition and defence of Ricardo's theory of rent; and the Essays contain a very clear and formidable criticism of Bastiat's economic doctrines.

Professor Cairnes's son, CAPTAIN W.E. CAIRNES (1862-1906), was an able writer on military subjects, being author of An Absent-minded War (1900), The Coming Waterloo (1905), &c.

[v.04 p.0952]

CAIRNGORM, a yellow or brown variety of quartz, named from Cairngorm or Cairngorum, one of the peaks of the Grampian Mountains in Banffshire, Scotland. According to Mr E.H. Cunningham-Craig, the mineral occurs in crystals lining cavities in highly-inclined veins of a fine-grained granite running through the coarser granite of the main mass: Shallow pits were formerly dug in the kaolinized granite for sake of the cairngorm and the mineral was also found as pebbles in the bed of the river Avon. Cairngorm is a favourite ornamental stone in Scotland, being set in the lids of snuff-mulls, in the handles of dirks and in brooches for Highland costume. A rich sherry-yellow colour is much esteemed. Quartz of yellow and brown colour is often known in trade as "false topaz," or simply "topaz." Such quartz is found at many localities in Brazil, Russia and Spain. Much of the yellow quartz used in jewellery is said to be "burnt amethyst"; that is, it was originally amethystine quartz, the colour of which has been modified by heat (see AMETHYST). Yellow quartz is sometimes known as citrine; when the quartz presents a pale brown tint it is called "smoky quartz"; and when the brown is so deep that the stone appears almost black it is termed morion. The brown colour has been referred to the presence of titanium.

CAIRNS, HUGH MCCALMONT CAIRNS, 1ST EARL (1819-1885), Irish statesman, and lord chancellor of England, was born at Cultra, Co. Down, Ireland, on the 27th of December 1819. His father, William Cairns, formerly a captain in the 47th regiment, came of a family[1] of Scottish origin, which migrated to Ireland in the time of James I. Hugh Cairns was his second son, and was educated at Belfast academy and at Trinity College, Dublin, graduating with a senior moderatorship in classics in 1838. In 1844 he was called to the bar at the Middle Temple, to which he had migrated from Lincoln's Inn. During his first years at the chancery bar, Cairns showed little promise of the eloquence which afterwards distinguished him. Never a rapid speaker, he was then so slow and diffident, that he feared that this defect might interfere with his legal career. Fortunately he was soon able to rid himself of the idea that he was only fit for practice as a conveyancer. In 1852 he entered parliament as member for Belfast, and his Inn, on his becoming a Q.C. in 1856, made him a bencher.

In 1858 Cairns was appointed solicitor-general, and was knighted, and in May of that year made two of his most brilliant and best-remembered speeches in the House of Commons. In the first, he defended the action of Lord Ellenborough, who, as president of the board of control, had not only censured Lord Canning for a proclamation issued by him as governor-general of India but had made public the despatch in which the censure was conveyed. On the other occasion referred to, Sir Hugh Cairns spoke in opposition to Lord John Russell's amendment to the motion for the second reading of the government Reform Bill, winning the most cordial commendation of Disraeli. Disraeli's appreciation found an opportunity for displaying itself some years later, when in 1868 he invited him to be lord chancellor in the brief Conservative administration which followed Lord Derby's resignation of the leadership of his party. Meanwhile, Cairns had maintained his reputation in many other debates, both when his party was in power and when it was in opposition. In 1866 Lord Derby, returning to office, had made him attorney-general, and in the same year he had availed himself of a vacancy to seek the comparative rest of the court of appeal. While a lord justice he had been offered a peerage, and though at first unable to accept it, he had finally done so on a relative, a member of the wealthy family of McCalmont, providing the means necessary for the endowment of a title.

The appointment of Baron Cairns of Garmoyle as lord chancellor in 1868 involved the superseding of Lord Chelmsford, an act which apparently was carried out by Disraeli with less tact than might have been expected of him. Lord Chelmsford bitterly declared that he had been sent away with less courtesy than if he had been a butler, but the testimony of Lord Malmesbury is strong that the affair was the result of an understanding arrived at when Lord Chelmsford took office. Disraeli held office on this occasion for a few months only, and when Lord Derby died in 1869, Lord Cairns became the leader of the Conservative opposition in the House of Lords. He had distinguished himself in the Commons by his resistance to the Roman Catholics' Oath Bill brought in in 1865; in the Lords, his efforts on behalf of the Irish Church were equally strenuous. His speech on Gladstone's Suspensory Bill was afterwards published as a pamphlet, but the attitude which he and the peers who followed him had taken up, in insisting on their amendments to the preamble of the bill, was one difficult to maintain, and Lord Cairns made terms with Lord Granville in circumstances which precluded his consulting his party first. He issued a circular to explain his action in taking a course for which many blamed him. Viewed dispassionately, the incident appears to have exhibited his statesmanlike qualities in a marked degree, for he secured concessions which would have been irretrievably lost by continued opposition. Not long after this, Lord Cairns resigned the leadership of his party in the upper house, but he had to resume it in 1870 and took a strong part in opposing the Irish Land Bill in that year. On the Conservatives coming into power in 1874, he again became lord chancellor; in 1878 he was made Viscount Garmoyle and Earl Cairns; and in 1880 his party went out of office. In opposition he did not take as prominent a part as previously, but when Lord Beaconsfield died in 1881, there were some Conservatives who considered that his title to lead the party was better than that of Lord Salisbury. His health, however, never robust, had for many years shown intermittent signs of failing. He had periodically made enforced retirements to the Riviera, and for many years had had a house at Bournemouth, and it was here that he died on the 2nd of April 1885.

Cairns was a great lawyer, with an immense grasp of first principles and the power to express them; his judgments taking the form of luminous expositions or treatises upon the law governing the case before him, rather than of controversial discussions of the arguments adduced by counsel or of analysis of his own reasons. Lucidity and logic were the leading characteristics of his speeches in his professional capacity and in the political arena. In an eloquent tribute to his memory in the House of Lords, Lord Chief Justice Coleridge expressed the high opinion of the legal profession upon his merits and upon the severe integrity and single-minded desire to do his duty, which animated him in his selections for the bench. His piety was reflected by that of his great opponent, rival and friend, Lord Selborne. Like Lord Selborne and Lord Hatherley, Cairns found leisure at his busiest for teaching in the Sunday-school, but it is not recorded of them (as of him) that they refused to undertake work at the bar on Saturdays, in order to devote that day to hunting. He used to say that his great incentive to hard work at his profession in early days was his desire to keep hunters, and he retained his keenness as a sportsman as long as he was able to indulge it. Of his personal characteristics, it may be said that he was a spare man, with a Scottish, not an Irish, cast of countenance. He was scrupulously neat in his personal appearance, faultless in bands and necktie, and fond of wearing a flower in his button-hole. His chilly manner, coupled with his somewhat austere religious principles, had no doubt much to do with the fact that he was never a popular man. His friends claimed for him a keen sense of humour, but it was not to be detected by those whose knowledge of him was professional rather than personal. Probably he thought the exhibition of humour incompatible with the dignity of high judicial position. Of his legal attainments there can be no doubt. His influence upon the legislation of the day was largely felt where questions affecting religion and the Church were involved and in matters peculiarly affecting his own profession. His power was felt, as has been said, both when he was in office and when his party was in opposition. He had been chairman of the committee on judicature reform, and although he was not in office when the Judicature Act was passed, all the reforms in the legal procedure of his day owed much to him. He took part, when out of office, in the passing of the Married Women's Property Act, and was directly responsible for the Conveyancing Acts of 1881-1882, and [v.04 p.0953] for the Settled Land Act. Many other statutes in which he was largely concerned might be quoted. His judgments are to be found in the Law Reports and those who wish to consider his oratory should read the speeches above referred to, or that delivered in the House of Lords on the Compensation for Disturbance Bill in 1880, and his memorable criticism of Mr Gladstone's policy in the Transvaal, after Majuba Hill. (See Hansard and The Times, 1st of April 1881.) His style of delivery was, as a rule, cold to a marked degree. The term "frozen oratory" has been applied to his speeches, and it has been said of them that they flowed "like water from a glacier.... The several stages of his speech are like steps cut out in ice, as sharply defined, as smooth and as cold." Lord Caims married in 1856 Mary Harriet, eldest daughter of John McNeill, of Parkmount, Co. Antrim, by whom he had issue five sons and two daughters. He was succeeded in the earldom by his second but eldest surviving son, Arthur William (1861-1890), who left one daughter, and from whom the title passed to his two next younger brothers in succession, Herbert John, third earl (1863-1905), and Wilfrid Dallas, fourth earl (b. 1865).

CAIRNS, JOHN (1818-1892), Scottish Presbyterian divine, was born at Ayton Hill, Berwickshire, on the 23rd of August 1818, the son of a shepherd. He went to school at Ayton and Oldcambus, Berwickshire, and was then for three years a herd boy, but kept up his education. In 1834 he entered Edinburgh University, but during 1836 and 1837, owing to financial straits, taught in a school at Ayton. In November 1837 he returned to Edinburgh, where he became the most distinguished student of his time, graduating M.A. in 1841, first in classics and philosophy and bracketed first in mathematics. While at Edinburgh he organized the Metaphysical Society along with A. Campbell Fraser and David Masson. He entered the Presbyterian Secession Hall in 1840, and in 1843 wrote an article in the Secession Magazine on the Free Church movement, which aroused the interest of Thomas Chalmers. The years 1843-1844 he spent at Berlin studying German philosophy and theology. He was licensed as preacher on the 3rd of February 1845, and on the 6th of August ordained as minister of Golden Square Church, Berwick-on-Tweed. There his preaching was distinguished by its impressiveness and by a broad and unaffected humanity. He had many "calls" to other churches, but chose to remain at Berwick. In 1857 he was one of the representatives at the meeting of the Evangelical Alliance in Berlin, and in 1858 Edinburgh University conferred on him an honorary D.D. In the following year he declined an invitation to become principal of Edinburgh University. In 1872 he was elected moderator of the United Presbyterian Synod and represented his church in Paris at the first meeting of the Reformed Synod of France. In May 1876, he was appointed joint professor of systematic theology and apologetics with James Harper, principal of the United Presbyterian Theological College, whom he succeeded as principal in 1879. He was an indefatigable worker and speaker, and in order to facilitate his efforts in other countries and other literatures he learnt Arabic, Norse, Danish and Dutch. In 1890 he visited Berlin and Amsterdam to acquaint himself with the ways of younger theologians, especially with the Ritschlians, whose work he appreciated but did not accept as final. On his return he wrote a long article on "Recent Scottish Theology" for the Presbyterian and Reformed Review, for which he read over every theological work of note published in Scotland during the preceding half-century. He died on the 12th of March, 1892, at Edinburgh. Among his principal publications are An Examination of Ferrier's "Knowing and Being," and the Scottish Philosophy—(a work which gave him the reputation of being an independent Hamiltonian in philosophy); Memoir of John Brown, D.D. (1860); Romanism and Rationalism (1863); Outlines of Apologetical Theology (1867); The Doctrine of the Presbyterian Church (1876); Unbelief in the 18th Century (1881); Doctrinal Principles of the United Presbyterian Church (Dr Blair's Manual, 1888).

(D. MN.)

CAIRNS, a seaport of Nares county, Queensland, Australia, 890 m. direct N.N.W. of Brisbane. Pop. (1901) 3557. The town lies parallel with the sea, on the western shore of Trinity Bay, with an excellent harbour, and a long beach, finely timbered. Cairns is the natural outlet for the gold-fields, tin-mines and silver-fields of the district and for the rich copper district of Chillagoe. A government railway, 48 m. long, runs to Mareeba, whence a private company's line continues to Mungana, 100 m. W. There is also a line belonging to a private company connecting Chillagoe with Mareeba. In the vicinity of Cairns are extensive sugar plantations, with sugar mills and refineries; the culture of coffee and tobacco has rapidly extended; bananas, pine-apples and other fruits are exported in considerable quantities and there is a large industry in cedar. The Barron Falls, among the finest in Australia, are near Kuranda, 19 m. from Cairns. Cairns became a municipality in 1885.

CAIRO (Arabic Misr-al-Kahira, or simply Misr), the capital of modern Egypt and the most populous city in Africa, on the Nile, 12 m. S. of the apex of the Delta, in 30 deg. 3' N. and 31 deg. 21' E. It is 130 m. S.E. of Alexandria, and 148 E. of Suez by rail, though only 84 m. from the last-named port by the overland route across the desert, in use before the opening of the Suez Canal. Cairo occupies a length of 5 m. on the east bank of the Nile, stretching north from the old Roman fortress of Babylon, and covers an area of about 8 sq. m. It is built partly on the alluvial plain of the Nile valley and partly on the rocky slopes of the Mokattam hills, which rise 550 ft. above the town.

The citadel, which is built on a spur of the Mokattam hills, occupies the S.E. angle of the city. The prospect from the ramparts of this fortress is one of striking picturesqueness and beauty. Below lies the city with its ancient walls and lofty towers, its gardens and squares, its palaces and its mosques, with their delicately-carved domes and minarets covered with fantastic tracery, the port of Bulak, the gardens and palace of Shubra, the broad river studded with islands, the valley of the Nile dotted with groups of trees, with the pyramids on the north horizon, and on the east the barren cliffs, backed by a waste of sand. Since the middle of the 19th century the city has more than doubled in size and population. The newer quarters, situated near the river, are laid out in the fashion of French cities, but the eastern parts of the town retain, almost unimpaired, their Oriental aspect, and in scores of narrow, tortuous streets, and busy bazaars it is easy to forget that there has been any change from the Cairo of medieval times. Here the line of fortifications still marks the eastern limits of the city, though on the north large districts have grown up beyond the walls. Neither on the south nor towards the river are there any fortifications left.

Principal Quarters and Modern Buildings.—From the citadel a straight road, the Sharia Mehemet Ali, runs N. to the Ezbekia (Ezbekiyeh) Gardens, which cover over 20 acres, and form the central point of the foreign colony. North and west of the Ezbekia runs the Ismailia canal, and on the W. side of the canal, about half a mile N. of the Gardens, is the Central railway station, approached by a broad road, the Sharia Clot Bey. The Arab city and the quarters of the Copts and Jews lie E. of the two streets named. West of the Ismailia canal lies the Bulak quarter, the port or riverside district. At Bulak are the arsenal, foundry and railway works, a paper manufactory and the government printing press, founded by Mehemet Ali. A little distance S.E. of the Ezbekia is the Place Atabeh, the chief point of intersection of the electric tramways which serve the newer parts of the town. From the Place Atabeh a narrow street, the Muski, leads E. into the heart of the Arab city. Another street leads S.W. to the Nile, at the point where the Kasr en Nil or Great Nile bridge spans the river, leading to Gezira Bulak, an island whereon is a palace, now turned into a hotel, polo, cricket and tennis grounds, and a racecourse. The districts between the bridge, the Ezbekia [v.04 p.0954] and the Ismailia canal, are known as the Ismailia and Tewfikia quarters, after the khedives in whose reigns they were laid out. The district immediately south of the bridge is called the Kasr el-Dubara quarter. Abdin Square, which occupies a central position, is connected with Ezbekia Gardens by a straight road. The narrow canal, El Khalig, which branched from the Nile at Old Cairo and traversed the city from S.W. to N.E., was filled up in 1897, and an electric tramway runs along the road thus made. With the filling up of the channel the ancient festival of the cutting of the canal came to an end.

The government offices and other modern public buildings are nearly all in the western half of the city. On the south side of the Ezbekia are the post office, the courts of the International Tribunals, and the opera house. On the east side are the bourse and the Credit Lyonnais, on the north the buildings of the American mission. On or near the west side of the gardens are most of the large and luxurious hotels which the city contains for the accommodation of Europeans. Facing the river immediately north of the Great Nile bridge are the large barracks, called Kasr-en-Nil, and the new museum of Egyptian antiquities (opened in 1902). South of the bridge are the Ismailia palace (a khedivial residence), the British consulate general, the palace of the khedive's mother, the medical school and the government hospital. Farther removed from the river are the offices of the ministries of public works and of war—a large building surrounded by gardens—and of justice and finance. On the east side of Abdin Square is Abdin palace, an unpretentious building used for official receptions. Adjoining the palace are barracks. N.E. of Abdin Square, in the Sharia Mehemet Ali, is the Arab museum and khedivial library. Near this building are the new courts of the native tribunals. Private houses in these western districts consist chiefly of residential flats, though in the Kasr el-Dubara quarter are many detached residences.

The Oriental City.—The eastern half of Cairo is divided into many quarters. These quarters were formerly closed at night by massive gates. A few of these gates remain. In addition to the Mahommedan quarters, usually called after the trade of the inhabitants or some notable building, there are the Copt or Christian quarter, the Jews' quarter and the old "Frank" quarter. The last is the Muski district where, since the days of Saladin, "Frank" merchants have been permitted to live and trade. Some of the principal European shops are still to be found in this street. The Copt and Jewish quarters lie north of the Muski. The Coptic cathedral, dedicated to St Mark, is a modern building in the basilica style. The oldest Coptic church in Cairo is, probably, the Keniset-el-Adra, or Church of the Virgin, which is stated to preserve the original type of Coptic basilica. The Coptic churches in the city are not, however, of so much interest as those in Old Cairo (see below). In the Copt quarter are also Armenian, Syrian, Maronite, Greek and Roman Catholic churches. In the Copt and Jewish quarters the streets, as in the Arab quarters, are winding and narrow. In them the projecting upper stories of the houses nearly meet. Sebils or public fountains are numerous. These fountains are generally two-storeyed, the lower chamber enclosing a well, the upper room being often used for scholastic purposes. Many of the fountains are fine specimens of Arab architecture. While the houses of the poorer classes are mean and too often dirty, in marked contrast are the houses of the wealthier citizens, built generally in a style of elaborate arabesque, the windows shaded with projecting cornices of graceful woodwork (mushrebiya) and ornamented with stained glass. A winding passage leads through the ornamental doorway into the court, in the centre of which is a fountain shaded with palm-trees. The principal apartment is generally paved with marble; in the centre a decorated lantern is suspended over a fountain, while round the sides are richly inlaid cabinets and windows of stained glass; and in a recess is the divan, a low, narrow, cushioned seat. The basement storey is generally built of the soft calcareous stone of the neighbouring hills, and the upper storey, which contains the harem, of painted brick. The shops of the merchants are small and open to the street. The greater part of the trade is done, however, in the bazaars or markets, which are held in large khans or storehouses, of two storeys and of considerable size. Access to them is gained from the narrow lanes which usually surround them. The khans often possess fine gateways. The principal bazaar, the Khan-el-Khalil, marks the site of the tombs of the Fatimite caliphs.
