CABRA, a town of southern Spain, in the province of Cordova, 28 m. S.E. by S. of Cordova, on the Jaen-Malaga railway. Pop. (1900) 13,127. Cabra is built in a fertile valley between the Sierra de Cabra and the Sierra de Montilla, which together form the watershed between the rivers Cabra and Guadajoz. The town was for several centuries an episcopal see. Its chief buildings are the cathedral, originally a mosque, and the ruined castle, which is the chief among many interesting relics of Moorish rule. The neighbouring fields of clay afford material for the manufacture of bricks and pottery; coarse cloth is woven in the town; and there is a considerable trade in farm produce. Cabra is the Roman Baebro or Aegabro. It was delivered from the Moors by Ferdinand III. of Castile in 1240, and entrusted to the Order of Calatrava; in 1331 it was recaptured by the Moorish king of Granada; but in the following century it was finally reunited to Christian Spain.

CABRERA, RAMON (1806-1877), Carlist general, was born at Tortosa, province of Tarragona, Spain, on the 27th of December 1806. As his family had in their gift two chaplaincies, young Cabrera was sent to the seminary of Tortosa, where he made himself conspicuous as an unruly pupil, ever mixed up in disturbances and careless in his studies. After he had taken minor orders, the bishop refused to ordain him as a priest, telling him that the Church was not his vocation, and that everything in him showed that he ought to be a soldier. Cabrera followed this advice and took part in Carlist conspiracies on the death of Ferdinand VII. The authorities exiled him and he absconded to Morella to join the forces of the pretender Don Carlos. In a very short time he rose by sheer daring, fanaticism and ferocity to the front rank among the Carlist chiefs who led the bands of Don Carlos in Catalonia, Aragon and Valencia. As a raider he was often successful, and he was many times wounded in the brilliant fights in which he again and again defeated the generals of Queen Isabella. He sullied his victories by acts of cruelty, shooting prisoners of war whose lives he had promised to spare and not respecting the lives and property of non-combatants. The queen's generals seized his mother as a hostage, whereupon Cabrera shot several mayors and officers. General Nogueras unfortunately caused the mother of Cabrera to be shot, and the Carlist leader then started upon a policy of reprisals so merciless that the people nicknamed him "The Tiger of the Maeztrazgo". It will suffice to say that he shot 1110 prisoners of war, 100 officers and many civilians, including the wives of four leading Isabellinos, to avenge his mother. When Marshal Espartero induced the Carlists of the north-western provinces, with Maroto at their head, to submit in accordance with the Convention of Vergara, which secured the recognition of the rank and titles of 1000 Carlist officers, Cabrera held out in Central Spain for nearly a year. Marshals Espartero and O'Donnell, with the bulk of the Isabellino armies, had to conduct a long and bloody campaign against Cabrera before they succeeded in driving him into French territory in July 1840. The government of Louis Philippe kept him in a fortress for some months and then allowed him to go to England, where he quarrelled with the pretender, disapproving of his abdication in favour of the count of Montemolin. In 1848 Cabrera reappeared in the mountains of Catalonia at the head of Carlist bands. These were soon dispersed and he again fled to France. After this last effort he did not take a very active part in the propaganda and subsequent risings of the Carlists, who, however, continued to consult him. He took offence when new men, not a few of them quondam regular officers, became the advisers and lieutenants of Don Carlos in the war which lasted more or less from 1870-1876. Indeed, his long residence in England, his marriage with Miss Richards, and his prolonged absence from Spain had much shaken his devotion to his old cause and belief in its success. In March 1875 Cabrera sprang upon Don Carlos a manifesto in which he called upon the adherents of the pretender to follow his own example and submit to the restored monarchy of Alphonso XII., the son of Queen Isabella, who recognized the rank of captain-general and the title of count of Morella conferred on Cabrera by [v.04 p.0924] the first pretender. Only a very few insignificant Carlists followed Cabrera's example, and Don Carlos issued a proclamation declaring him a traitor and depriving him of all his honours and titles. Cabrera, who was ever afterwards regarded with contempt and execration by the Carlists, died in London on the 24th of May 1877. He did not receive much attention from the majority of his fellow-countrymen, who commonly said that his disloyalty to his old cause had proved more harmful to him than beneficial to the new state of things. A pension which had been granted to his widow was renounced by her in 1899 in aid of the Spanish treasury after the loss of the colonies.

CACCINI, GIULIO (1558-1615?), Italian musical composer, also known as Giulio Romano, but to be distinguished from the painter of that name, was born at Rome about 1558, and in 1578 entered the service of the grand duke of Tuscany at Florence. He collaborated with J. Peri in the early attempts at musical drama which were the ancestors of modern opera (Dafne, 1594, and Euridice, 1600), produced at Florence by the circle of musicians and amateurs which met at the houses of G. Bardi and Corsi. He also published in 1601 Le nuove musiche, a collection of songs which is of great importance in the history of singing as well as in that of the transition period of musical composition. He was a lyric composer rather than a dramatist like Peri, and the genuine beauty of his works makes them acceptable even at the present day.

CACERES, a province of western Spain, formed in 1833 of districts taken from Estremadura, and bounded on the N. by Salamanca and Avila, E. by Toledo, S. by Badajoz, and W. by Portugal. Pop. (1900) 362,164; area, 7667 sq. m. Caceres is the largest of Spanish provinces, after Badajoz, and one of the most thinly peopled, although the number of its inhabitants steadily increases. Except for the mountainous north, where the Sierra de Gata and the Sierra de Gredos mark respectively the boundaries of Salamanca and Avila, and in the south-east, where there are several lower ranges, almost the entire surface is flat or undulating, with wide tracts of moorland and thin pasture. There is little forest and many districts suffer from drought. The whole province, except the extreme south, belongs to the basin of the river Tagus, which flows from east to west through the central districts, and is joined by several tributaries, notably the Alagon and Tietar, from the north, and the Salor and Almonte from the south. The climate is temperate except in summer, when hot east winds prevail. Fair quantities of grain and olives are raised, but as a stock-breeding province Caceres ranks second only to Badajoz. In 1900 its flocks and herds numbered more than 1,000,000 head. It is famed for its sheep and pigs, and exports wool, hams and the red sausages called embutidos. Its mineral resources are comparatively insignificant. The total number of mines at work in 1903 was only nine; their output consisted of phosphates, with a small amount of zinc and tin. Brandy, leather and cork goods, and coarse woollen stuffs are manufactured in many of the towns, but the backwardness of education, the lack of good roads, and the general poverty retard the development of commerce. The more northerly of the two Madrid-Lisbon railways enters the province on the east; passes south of Plasencia, where it is joined by the railway from Salamanca, on the north; and reaches the Portuguese frontier at Valencia de Alcantara. This line is supplemented by a branch from Arroyo to the city of Caceres, and thence southwards to Merida in Badajoz. Here it meets the railways from Seville and Cordova. The principal towns of Caceres are Caceres (pop. 1900, 16,933); Alcantara (3248), famous for its Roman bridge; Plasencia (8208); Trujillo (12,512), and Valencia de Alcantara (9417). These are described in separate articles. Arroyo, or Arroyo del Puerco (7094), is an important agricultural market. (See also ESTREMADURA.)

CACERES, the capital of the Spanish province of Caceres, about 20 m. S. of the river Tagus, on the Caceres-Merida railway, and on a branch line which meets the more northerly of the two Madrid-Lisbon railways at Arroyo, 10 m. W. Pop. (1900) 16,933. Caceres occupies a conspicuous eminence on a low ridge running east and west. At the highest point rises the lofty tower of San Mateo, a fine Gothic church, which overlooks the old town, with its ancient palaces and massive walls, gateways and towers. Many of the palaces, notably those of the provincial legislature, the dukes of Abrantes, and the counts of la Torre, are good examples of medieval domestic architecture. The monastery and college of the Jesuits, formerly one of the finest in Spain, has been secularized and converted into a hospital. In the modern town, built on lower ground beyond the walls, are the law courts, town-hall, schools and the palace of the bishops of Coria (pop. 3124), a town on the river Alagon. The industries of Caceres include the manufacture of cork and leather goods, pottery and cloth. There is also a large trade in grain, oil, live-stock and phosphates from the neighbouring mines. The name of Caceres is probably an adaptation of Los Alcazares, from the Moorish Alcazar, a tower or castle; but it is frequently connected with the neighbouring Castra Caecilia and Castra Servilia, two Roman camps on the Merida-Salamanca road. The town is of Roman origin and probably stands on the site of Norba Caesarina. Several Roman inscriptions, statues and other remains have been discovered.

CACHAR, or KACHAR, a district of British India, in the province of Eastern Bengal and Assam. It occupies the upper basin of the Surma or Barak river, and is bounded on three sides by lofty hills. Its area is 3769 sq. m. It is divided naturally between the plain and hills. The scenery is beautiful, the hills rising generally steeply and being clothed with forests, while the plain is relieved of monotony by small isolated undulations and by its rich vegetation. The Surma is the chief river, and its principal tributaries from the north are the Jiri and Jatinga, and from the south the Sonai and Daleswari. The climate is extremely moist. Several extensive fens, notably that of Chatla, which becomes lakes in time of flood, are characteristic of the plain. This is alluvial and bears heavy crops of rice, next to which in importance is tea. The industry connected with the latter crop employs large numbers of the population; manufacturing industries are otherwise slight. The Assam-Bengal railway serves the district, including the capital town of Silchar. The population of the district in 1901 was 455,593, and showed a large increase, owing in great part to immigration from the adjacent district of Sylhet. The plain is the most thickly populated part of the district; in the North Cachar Hills the population is sparse. About 66% of the population are Hindus and 29% Mahommedans. There are three administrative subdivisions of the district: Silchar, Hailakandi and North Cachar. The district takes name from its former rulers of the Kachari tribe, of whom the first to settle here did so early in the 18th century, after being driven out of the Assam valley in 1536, and from the North Cachar Hills in 1706, by the Ahoms. About the close of the 18th century the Burmans threatened to expel the Kachari raja and annex his territory; the British, however, intervened to prevent this, and on the death of the last raja without heir in 1830 they obtained the territory under treaty. A separate principality which had been established in the North Cachar Hills earlier in the century by a servant of the raja, and had been subsequently recognized as such, was taken over by the British in 1854 owing to the misconduct of its rulers. The southern part of the district was raided several times in the 19th century by the turbulent tribe of Lushais.

CACHOEIRA, an important inland town of Bahia, Brazil, on the Paraguassu river, about 48 m. from Sao Salvador, with which it is connected by river-boats. Pop. (1890) of the city, 12,607; of the municipality, 48,352. The Bahia Central railway starts from this point and extends S. of W. to Machado Portella, 161 m., and N. to Feira de Santa Anna, 28 m. Although badly situated on the lower levels of the river (52 ft. above sea-level) and subject to destructive floods, Cachoeira is one of the most thriving commercial and industrial centres in the state. It exports sugar and tobacco and is noted for its cigar and cotton factories.

CACTUS. This word, applied in the form of [Greek: Kaktos] by the ancient Greeks to some prickly plant, was adopted by Linnaeus as the name of a group of curious succulent or fleshy-stemmed plants, most of them prickly and leafless, some of which produce [v.04 p.0925] beautiful flowers, and are now so popular in our gardens that the name has become familiar. As applied by Linnaeus, the name Cactus is almost conterminous with what is now regarded as the natural order Cactaceae, which embraces several modern genera. It is one of the few Linnaean generic terms which have been entirely set aside by the names adopted for the modern divisions of the group.



The Cacti may be described in general terms as plants having a woody axis, overlaid with thick masses of cellular tissue forming the fleshy stems. These are extremely various in character and form, being globose, cylindrical, columnar or flattened into leafy expansions or thick joint-like divisions, the surface being either ribbed like a melon, or developed into nipple-like protuberances, or variously angular, but in the greater number of the species furnished copiously with tufts of horny spines, some of which are exceedingly keen and powerful. These tufts show the position of buds, of which, however, comparatively few are developed. The stems are in most cases leafless, using the term in a popular sense; the leaves, if present at all, being generally reduced to minute scales. In one genus, however, Peireskia, the stems are less succulent, and the leaves, though rather fleshy, are developed in the usual form. The flowers are frequently large and showy, and are generally attractive from their high colouring. In one group, represented by Cereus, they consist of a tube, more or less elongated, on the outer surface of which, towards the base, are developed small and at first inconspicuous scales, which gradually increase in size upwards, and at length become crowded, numerous and petaloid, forming a funnel-shaped blossom, the beauty of which is much enhanced by the multitude of conspicuous stamens which with the pistil occupy the centre. In another group, represented by Opuntia (fig. 1), the flowers are rotate, that is to say, the long tube is replaced by a very short one. At the base of the tube, in both groups, the ovary becomes developed into a fleshy (often edible) fruit, that produced by the Opuntia being known as the prickly pear or Indian fig.

The principal modern genera are grouped by the differences in the flower-tube just explained. Those with long-tubed flowers comprise the genera Melocactus, Mammillaria, Echinocactus, Cereus, Pilocereus, Echinopsis, Phyllocactus, Epiphyllum, &c.; while those with short-tubed flowers are Rhipsalis, Opuntia, Peireskia, and one or two of minor importance. Cactaceae belong almost entirely to the New World; but some of the Opuntias have been so long distributed over certain parts of Europe, especially on the shores of the Mediterranean and the volcanic soil of Italy, that they appear in some places to have taken possession of the soil, and to be distinguished with difficulty from the aboriginal vegetation. The habitats which they affect are the hot, dry regions of tropical America, the aridity of which they are enabled to withstand in consequence of the thickness of their skin and the paucity of evaporating pores or stomata with which they are furnished,—these conditions not permitting the moisture they contain to be carried off too rapidly; the thick fleshy stems and branches contain a store of water. The succulent fruits are not only edible but agreeable, and in fevers are freely administered as a cooling drink. The Spanish Americans plant the Opuntias around their houses, where they serve as impenetrable fences.

MELOCACTUS, the genus of melon-thistle or Turk's-cap cactuses, contains, according to a recent estimate, about 90 species, which inhabit chiefly the West Indies, Mexico and Brazil, a few extending into New Granada. The typical species, M. communis, forms a succulent mass of roundish or ovate form, from 1 ft. to 2 ft. high, the surface divided into numerous furrows like the ribs of a melon, with projecting angles, which are set with a regular series of stellated spines—each bundle consisting of about five larger spines, accompanied by smaller but sharp bristles—and the tip of the plant being surmounted by a cylindrical crown 3 to 5 in. high, composed of reddish-brown, needle-like bristles, closely packed with cottony wool. At the summit of this crown the small rosy-pink flowers are produced, half protruding from the mass of wool, and these are succeeded by small red berries. These strange plants usually grow in rocky places with little or no earth to support them; and it is said that in times of drought the cattle resort to them to allay their thirst, first ripping them up with their horns and tearing off the outer skin, and then devouring the moist succulent parts. The fruit, which has an agreeably acid flavour, is frequently eaten in the West Indies. The Melocacti are distinguished by the distinct cephalium or crown which bears the flowers.

MAMMILLARIA.—This genus, which comprises nearly 300 species, mostly Mexican, with a few Brazilian and West Indian, is called nipple cactus, and consists of globular or cylindrical succulent plants, whose surface instead of being cut up into ridges with alternate furrows, as in Melocactus, is broken up into teat-like cylindrical or angular tubercles, spirally arranged, and terminating in a radiating tuft of spines which spring from a little woolly cushion. The flowers issue from between the mammillae, towards the upper part of the stem, often disposed in a zone just below the apex, and are either purple, rose-pink, white or yellow, and of moderate size. The spines are variously coloured, white and yellow tints predominating, and from the symmetrical arrangement of the areolae or tufts of spines they are very pretty objects, and are hence frequently kept in drawing-room plant cases. They grow freely in a cool greenhouse.



ECHINOCACTUS (fig. 2) is the name given to the genus bearing the popular name of hedgehog cactus. It comprises some 200 species, distributed from the south-west United States to Brazil and Chile. They have the fleshy stems characteristic of the order, these being either globose, oblong or cylindrical, and either ribbed as in Melocactus, or broken up into distinct tubercles, and most of them armed with stiff sharp pines, set in little woolly cushions occupying the place of the buds. The flowers, produced near the apex of the plant, are generally large and showy, yellow and rose being the prevailing colours. They are succeeded by succulent fruits, which are exserted, and frequently scaly or spiny, in which respects this genus differs both from Melocactus and Mamrmllaria, which have the fruits immersed and smooth. One of the most interesting species is the E. ingens, of which some very large plants have been from time to time imported. These large plants have from 40 to 50 ridges, on which the buds and clusters of spines are sunk at intervals, the aggregate number of the spines having been in some cases computed at upwards of 50,000 on a single plant. These spines are used by the Mexicans as toothpicks. The plants are slow growers and must have plenty of sun heat; they require sandy loam with a mixture of sand and bricks finely broken and must be kept dry in winter.

CEREUS.—This group bears the common name of torch thistle. It comprises about 100 species, largely Mexican but scattered through South America and the West Indies. The stems are columnar or elongated, some of the latter creeping on the ground or climbing up the trunks of trees, rooting as they grow. C. giganteus, the largest and most striking species of the genus, is a native of hot, arid, desert regions of New Mexico, growing there in rocky valleys and on mountain sides, where the tall stems with their erect branches have the appearance of telegraph poles. The stems grow to a height of from 50 ft. to 60 ft., and have a diameter of from 1 ft. to 2 ft., often unbranched, but sometimes furnished with branches [v.04 p.0926] which grow out at right angles from the main stem, and then curve upwards and continue their growth parallel to it; these stems have from twelve to twenty ribs, on which at intervals of about an inch are the buds with their thick yellow cushions, from which issue five or six large and numerous smaller spines. The fruits of this plant, which are green oval bodies from 2 to 3 in. long, contain a crimson pulp from which the Pimos and Papagos Indians prepare an excellent preserve; and they also use the ripe fruit as an article of food, gathering it by means of a forked stick attached to a long pole. The Cereuses include some of our most interesting and beautiful hothouse plants. In the allied genus Echinocereus, with 25 to 30 species in North and South America, the stems are short, branched or simple, divided into few or many ridges all armed with sharp, formidable spines. E. pectinatus produces a purplish fruit resembling a gooseberry, which is very good eating; and the fleshy part of the stem itself, which is called cabeza del viego by the Mexicans, is eaten by them as a vegetable after removing the spines.

PILOCEREUS, the old man cactus, forms a small genus with tallish erect, fleshy, angulate stems, on which, with the tufts of spines, are developed hair-like bodies, which, though rather coarse, bear some resemblance to the hoary locks of an old man. The plants are nearly allied to Cereus, differing chiefly in the floriferous portion developing these longer and more attenuated hair-like spines, which surround the base of the flowers and form a dense woolly head or cephalium. The most familiar species is P. senilis, a Mexican plant, which though seldom seen more than a foot or two in height in greenhouses, reaches from 20 ft. to 30 ft. in its native country.

ECHINOPSIS is another small group of species, separated by some authors from Cereus. They are dwarf, ribbed, globose or cylindrical plants; and the flowers, which are produced from the side instead of the apex of the stem, are large, and in some cases very beautiful, being remarkable for the length of the tube, which is more or less covered with bristly hairs. They are natives of Brazil, Bolivia and Chile.



PHYLLOCACTUS (fig. 3), the Leaf Cactus family, consists of about a dozen species, found in Central and tropical South America. They differ from all the forms already noticed in being shrubby and epiphytal in habit, and in having the branches compressed and dilated so as to resemble thick fleshy leaves, with a strong median axis and rounded woody base. The margins of these leaf-like branches are more or less crenately notched, the notches representing buds, as do the spine-clusters in the spiny genera; and from these crenatures the large showy flowers are produced. As garden plants the Phyllocacti are amongst the most ornamental of the whole family, being of easy culture, free blooming and remarkably showy, the colour of the flowers ranging from rich crimson, through rose-pink to creamy white. Cuttings strike readily in spring before growth has commenced; they should be potted in 3-in. or 4-in. pots, well drained, in loamy soil made very porous by the admixture of finely broken crocks and sand, and placed in a temperature of 60 deg.; when these pots are filled with roots they are to be shifted into larger ones, but overpotting must be avoided. During the summer they need considerable heat, all the light possible and plenty of air; in winter a temperature of 45 deg. or 50 deg. will be sufficient, and they must be kept tolerably dry at the root. By the spring they may have larger pots if required and should be kept in a hot and fairly moistened atmosphere; and by the end of June, when they have made new growth, they may be turned out under a south wall in the full sun, water being given only as required. In autumn they are to be returned to a cool house and wintered in a dry stove. The turning of them outdoors to ripen their growth is the surest way to obtain flowers, but they do not take on a free blooming habit until they have attained some age. They are often called Epiphyllum, which name is, however, properly restricted to the group next to be mentioned.

EPIPHYLLUM.—This name is now restricted to two or three dwarf branching Brazilian epiphytal plants of extreme beauty, which agree with Phyllocactus in having the branches dilated into the form of fleshy leaves, but differ in haying them divided into short truncate leaf-like portions, which are articulated, that is to say, provided with a joint by which they separate spontaneously; the margins are crenate or dentate, and the flowers, which are large and showy, magenta or crimson, appear at the apex of the terminal joints. In E. truncatum the flowers have a very different aspect from that of other Cacti, from the mouth of the tube being oblique and the segments all reflexed at the tip. The short separate pieces of which these plants are made up grow out of each other, so that the branches may be said to resemble leaves joined together endwise.

RHIPSALIS, a genus of about 50 tropical species, mainly in Central and South America, but a few in tropical Africa and Madagascar. It is a very heterogeneous group, being fleshy-stemmed with a woody axis, the branches being angular, winged, flattened or cylindrical, and the flowers small, short-tubed, succeeded by small, round, pea-shaped berries. Rhipsalis Cassytha, when seen laden with its white berries, bears some resemblance to a branch of mistletoe. All the species are epiphytal in habit.

OPUNTIA, the prickly pear, or Indian fig cactus, is a large typical group, comprising some 150 species, found in North America, the West Indies, and warmer parts of South America, extending as far as Chile. In aspect they are very distinct from any of the other groups. They are fleshy shrubs, with rounded, woody stems, and numerous succulent branches, composed in most of the species of separate joints or parts, which are much compressed, often elliptic or suborbicular, dotted over in spiral lines with small, fleshy, caducous leaves, in the axils of which are placed the areoles or tufts of barbed or hooked spines of two forms. The flowers are mostly yellow or reddish-yellow, and are succeeded by pear-shaped or egg-shaped fruits, having a broad scar at the top, furnished on their soft, fleshy rind with tufts of small spines. The sweet, juicy fruits of O. vulgaris and O. Tuna are much eaten under the name of prickly pears, and are greatly esteemed for their cooling properties. Both these species are extensively cultivated for their fruit in Southern Europe, the Canaries and northern Africa; and the fruits are not unfrequently to be seen in Covent Garden Market and in the shops of the leading fruiterers of the metropolis. O. vulgaris is hardy in the south of England.

The cochineal insect is nurtured on a species of Opuntia (O. coccinellifera), separated by some authors under the name of Nopalea, and sometimes also on O. Tuna. Plantations of the nopal and the tuna, which are called nopaleries, are established for the purpose of rearing this insect, the Coccus Cacti, and these often contain as many as 50,000 plants. The females are placed on the plants about August, and in four months the first crop of cochineal is gathered, two more being produced in the course of the year. The native country of the insect is Mexico, and it is there more or less cultivated; but the greater part of our supply comes from Colombia and the Canary Islands.

PEIRESKIA ACULEATA, or Barbadoes gooseberry, the Cactus peireskia of Linnaeus, differs from the rest in having woody stems and leaf-bearing branches, the leaves being somewhat fleshy, but otherwise of the ordinary laminate character. The flowers are subpaniculate, white or yellowish. This species is frequently used as a stock on which to graft other Cacti. There are about a dozen species known of this genus, mainly Mexican.

CADALSO VAZQUEZ, JOSE (1741-1782), Spanish author, was born at Cadiz on the 8th of October 1741. Before completing his twentieth year he had travelled through Italy, Germany, England, France and Portugal, and had studied the literatures of these countries. On his return to Spain he entered the army and rose to the rank of colonel. He was killed at the siege of Gibraltar, on the 27th of February 1782. His first published work was a rhymed tragedy, Don Sancho Garcia, Conde de Castilla (1771). In the following year he published his Eruditos a la Violeta, a prose satire on superficial knowledge, which was very successful. In 1773 appeared a volume of miscellaneous poems, Ocios de mi juventud, and after his death there was found among his MSS. a series of fictitious letters in the style of the Lettres Persanes; these were issued in 1793 under the title of Cartas marruecas. A good edition of his works appeared at Madrid, in 3 vols., 1823. This is supplemented by the Obras ineditas (Paris, 1894) published by R. Foulche-Delbosc.

[v.04 p.0927] CADAMOSTO (or CA DA MOSTO), ALVISE (1432-1477), a Venetian explorer, navigator and writer, celebrated for his voyages in the Portuguese service to West Africa. In 1454 he sailed from Venice for Flanders, and, being detained by contrary winds off Cape St Vincent, was enlisted by Prince Henry the Navigator among his explorers, and given command of an expedition which sailed (22nd of March 1455) for the south. Visiting the Madeira group and the Canary Islands (of both which he gives an elaborate account, especially concerned with European colonization and native customs), and coasting the West Sahara (whose tribes, trade and trade-routes he likewise describes in detail), he arrived at the Senegal, whose lower course had already, as he tells us, been explored by the Portuguese 60 m. up. The negro lands and tribes south of the Senegal, and especially the country and people of Budomel, a friendly chief reigning about 50 m. beyond the river, are next treated with equal wealth of interesting detail, and Cadamosto thence proceeded towards the Gambia, which he ascended some distance (here also examining races, manners and customs with minute attention), but found the natives extremely hostile, and so returned direct to Portugal. Cadamosto expressly refers to the chart he kept of this voyage. At the mouth of the Gambia he records an observation of the "Southern Chariot" (Southern Cross). Next year (1456) he went out again under the patronage of Prince Henry. Doubling Cape Blanco he was driven out to sea by contrary winds, and thus made the first known discovery of the Cape Verde Islands. Having explored Boavista and Santiago, and found them uninhabited, he returned to the African mainland, and pushed on to the Gambia, Rio Grande and Geba. Returning thence to Portugal, he seems to have remained there till 1463, when he reappeared at Venice. He died in 1477.

Besides the accounts of his two voyages, Cadamosto left a narrative of Pedro de Cintra's explorations in 1461 (or 1462) to Sierre Leone and beyond Cape Mesurado to El Mina and the Gold Coast; all these relations first appeared in the 1507 Vicenza Collection of Voyages and Travels (the Paesi novamente retrovati et novo mondo da Alberico Vesputio Florentino); they have frequently since been reprinted and translated (e.g. Ital. text in 1508, 1512, 1519, 1521, 1550 (Ramusio), &c.; Lat. version, Itinerarium Portugallensium, &c.,1508, 1532 (Grynaeus), &c.; Fr. Sensuyt le nouveau monde, &c., 1516, 1521; German, Newe unbekante Landte, &c., 1508). See also C. Schefer, Relation des voyages ... de Ca' da Mosto (1895); R.H. Major, Henry the Navigator (1868), pp. 246-287; C.R. Beazley, Henry the Navigator (1895), pp. 261-288; Yule Oldham, Discovery of the Cape Verde Islands (1892), esp. pp. 4-15.

It may be noted that Antonio Uso di Mare (Antoniotto Ususmaris), the Genoese, wrote his famous letter of the 12th of December 1455 (purporting to record a meeting with the last surviving descendant of the Genoese-Indian expedition of 1291, at or near the Gambia), after accompanying Cadamosto to West Africa; see Beazley, Dawn of Modern Geography (1892), iii. 416-418.

CADASTRE (a French word from the Late Lat. capitastrum, a register of the poll-tax), a register of the real property of a country, with details of the area, the owners and the value. A "cadastral survey" is properly, therefore, one which gives such information as the Domesday Book, but the term is sometimes used loosely of the Ordnance Survey of the United Kingdom (1=2500), which is on sufficiently large a scale to give the area of every field or piece of ground.

CADDIS-FLY and CADDIS-WORM, the name given to insects with a superficial resemblance to moths, sometimes referred to the Neuroptera, sometimes to a special order, the Trichoptera, in allusion to the hairy clothing of the body and wings. Apart from this feature the Trichoptera also differ from the typical Neuroptera in the relatively simple, mostly longitudinal neuration of the wings, the absence or obsolescence of the mandibles and the semi-haustellate nature of the rest of the mouth-parts. Although caddis-flies are sometimes referred to several families, the differences between the groups are of no great importance. Hence the insects may more conveniently be regarded as constituting the single family Phryganeidae. The larvae known as caddis-worms are aquatic. The mature females lay their eggs in the water, and the newly-hatched larvae provide themselves with cases made of various particles such as grains of sand, pieces of wood or leaves stuck together with silk secreted from the salivary glands of the insect. These cases differ greatly in structure and shape. Those of Phyrganea consist of bits of twigs or leaves cut to a suitable length and laid side by side in a long spirally-coiled band, forming the wall of a subcylindrical cavity. The cavity of the tube of Helicopsyche, composed of grains of sand, is itself spirally coiled, so that the case exactly resembles a small snail-shell in shape. One species of Limnophilus uses small but entire leaves; another, the shells of the pond-snail Planorbis; another, pieces of stick arranged transversely with reference to the long axis of the tube. To admit of the free inflow and outflow of currents of water necessary for respiration, which is effected by means of filamentous abdominal tracheal gills, the two ends of the tube are open. Sometimes the cases are fixed, but more often portable. In the latter case the larva crawls about the bottom of the water or up the stems of plants, with its thickly-chitinized head and legs protruding from the larger orifice, while it maintains a secure hold of the silk lining of the tube by means of a pair of strong hooks at the posterior end of its soft defenceless abdomen. Their food appears for the most part to be of a vegetable nature. Some species, however, are alleged to be carnivorous, and a North American form of the genus Hydropsyche is said to spin around the mouth of its burrow a silken net for the capture of small animal organisms living in the water. Before passing into the pupal stage, the larva partially closes the orifice of the tube with silk or pieces of stone loosely spun together and pervious to water. Through this temporary protection the active pupa, which closely resembles the mature insect, subsequently bites a way by means of its strong mandibles, and rising to the surface of the water casts the pupal integument and becomes sexually adult.

The above sketch may be regarded as descriptive of the life-history of a great majority of species of caddis-flies. It is only necessary here to mention one anomalous form, Enoicyla pusilla, in which the mature female is wingless and the larva is terrestrial, living in moss or decayed leaves.

Caddis-flies are universally distributed. Geologically they are known to date back to the Oligocene period, and wings believed to be referable to them have been found in Liassic and Jurassic beds.

CADDO, a confederacy of North American Indian tribes which gave its name to the Caddoan stock, represented in the south by the Caddos, Wichita and Kichai, and in the north by the Pawnee and Arikara tribes. The Caddos, now reduced to some 500, settled in western Oklahoma, formerly ranged over the Red River (Louisiana) country, in what is now Arkansas, northern Texas and Oklahoma. The native name of the confederacy is Hasinai, corrupted by the French into Asinais and Cenis. The Caddoan tribes were mostly agricultural and sedentary, and to-day they are distinguished by their industry and intelligence.

CADE, JOHN (d. 1450), commonly called JACK CADE, English rebel and leader of the rising of 1450, was probably an Irishman by birth, but the details of his early life are very scanty. He seems to have resided for a time in Sussex, to have fled from the country after committing a murder, and to have served in the French wars. Returning to England, he settled in Kent under the name of Aylmer and married a lady of good position. When the men of Kent rose in rebellion in May 1450, they were led by a man who took the name of Mortimer, and who has generally been regarded as identical with Cade. Mr James Gairdner, however, considers it probable that Cade did not take command of the rebels until after the skirmish at Sevenoaks on the 18th of June. At all events, it was Cade who led the insurgents from Blackheath to Southwark, and under him they made their way into London on the 3rd of July. A part of the populace was doubtless favourable to the rebels, but the opposing party gained strength when Cade and his men began to plunder. Having secured the execution of James Fiennes, Baron Say and Sele, and of William Crowmer, sheriff of Kent, Cade and his followers retired to Southwark, and on the 5th of July, after a fierce struggle on London Bridge, the citizens prevented them from re-entering the city. Cade then met the chancellor, John [v.04 p.0928] Kemp, archbishop of York, and William of Wayneflete, bishop of Winchester, and terms of peace were arranged. Pardons were drawn up, that for the leaders being in the name of Mortimer. Cade, however, retained some of his men, and at this time, or a day or two earlier, broke open the prisons in Southwark and released the prisoners, many of whom joined his band. Having collected some booty, he went to Rochester, made a futile attempt to capture Queenborough castle, and then quarrelled with his followers over some plunder. On the 10th of July a proclamation was issued against him in the name of Cade, and a reward was offered for his apprehension. Escaping into Sussex he was captured at Heathfield on the 12th. During the scuffle he had been severely wounded, and on the day of his capture he died in the cart which was conveying him to London. The body was afterwards beheaded and quartered, and in 1451 Cade was attainted.

CADENABBIA, a village of Lombardy, Italy, in the province of Como, about 15 m. N.N.E. by steamer from the town of Como. It is situated on the W. shore of the lake of Como, and owing to the great beauty of the scenery and of the vegetation, and its sheltered situation, is a favourite spring and autumn resort. The most famous of its villas is the Villa Carlotta, now the property of the duke of Saxe-Meiningen, which contains marble reliefs by Thorwaldsen, representing the triumph of Alexander, and statues by Canova.

CADENCE (through the Fr. from the Lat. cadentia, from cadere, to fall), a falling or sinking, especially as applied to rhythmical or musical sounds, as in the "fall" of the voice in speaking, the rhythm or measure of verses, song or dance. In music, the word is used of the closing chords of a musical phrase, which succeed one another in such a way as to produce, first an expectation or suspense, and then an impression of finality, indicating also the key strongly. "Cadenza," the Italian form of the same word, is used of a free flourish in a vocal or instrumental composition, introduced immediately before the close of a movement or at the end of the piece. The object is to display the performer's technique, or to prevent too abrupt a contrast between two movements. Cadenzas are usually left to the improvisation of the performer, but are sometimes written in full by the composer, or by some famous executant, as in the cadenza in Brahms's Violin Concerto, written by Joseph Joachim.

CADER IDRIS ("the Seat of Idris"), the second most imposing mountain in North Wales, standing in Merionethshire to the S. of Dolgelly, between the broad estuaries of the Mawddach and the Dovey. It is so called in memory of Idris Gawr, celebrated in the Triads as one of the three "Gwyn Serenyddion," or "Happy Astronomers," of Wales, who is traditionally supposed to have made his observations on this peak. Its loftiest point, known as Pen-y-gader, rises to the height of 2914 ft., and in clear weather commands a magnificent panorama of immense extent. The mountain is everywhere steep and rocky, especially on its southern side, which falls abruptly towards the Lake of Tal-y-llyn. Mention of Cader Idris and its legends is frequent in Welsh literature, old and modern.

CADET (through the Fr. from the Late Lat. capitettum, a diminutive of caput, head, through the Provencal form capdet), the head of an inferior branch of a family, a younger son; particularly a military term for an accepted candidate for a commission in the army or navy, who is undergoing training to become an officer. This latter use of the term arose in France, where it was applied to the younger sons of the noblesse who gained commissioned rank, not by serving in the ranks or by entering the ecoles militaires, but by becoming attached to corps without pay but with certain privileges. "Cadet Corps," in the British service, are bodies of boys or youths organized, armed and trained on volunteer military lines. Derived from "cadet," through the Scots form "cadee," comes "caddie," a messenger-boy, and particularly one who carries clubs at golf, and also the slang word "cad," a vulgar, ill-bred person.

CADGER (a word of obscure origin possibly connected with "catch"), a hawker or pedlar, a carrier of farm produce to market. The word in this sense has fallen into disuse, and now is used for a beggar or loafer, one who gets his living in more or less questionable ways.

CADI (qāḍī), a judge in a maḥkama or Mahommedan ecclesiastical court, in which decisions are rendered on the basis of the canon law of Islam (sharī 'a). It is a general duty, according to canon law, upon a Moslem community to judge legal disputes on this basis, and it is an individual duty upon the ruler of the community to appoint a cadi to act for the community. According to Shāfi'ite law, such a cadi must be a male, free, adult Moslem, intelligent, of unassailed character, able to see, hear and write, learned in the Koran, the traditions, the Agreement, the differences of the legal schools, acquainted with Arabic grammar and the exegesis of the Koran. He must not sit in a mosque, except under necessity, but in some open, accessible place. He must maintain a strictly impartial attitude of body and mind, accept no presents from the people of his district, and render judgment only when he is in a normal condition mentally and physically. He may not engage in any business. He shall ride to the place where he holds court, greeting the people on both sides. He shall visit the sick and those returned from a journey, and attend funerals. On some of these points the codes differ, and the whole is to be regarded as the ideal qualification, built up theoretically by the canonists.

(D. B. MA.)

CADILLAC, a city and the county seat of Wexford county, Michigan, U.S.A., on Lake Cadillac, about 95 m. N. by E. of Grand Rapids and about 85 m. N.W. of Bay City. Pop. (1890) 4461; (1900) 5997, of whom 1676 were foreign-born; (1904) 6893; (1910) 8375. It is served by the Ann Arbor and the Grand Rapids & Indiana railways. Cadillac overlooks picturesque lake scenery, and the good fishing for pike, pickerel and perch in the lake, and for brook trout in streams near by, attracts many visitors. Among the city's chief manufactures are hardwood lumber, iron, tables, crates and woodenware, veneer, flooring and flour. Cadillac was settled in 1871, was incorporated as a village under the name of Clam Lake in 1875, was chartered as a city under its present name (from Antoine de la Mothe Cadillac) in 1877, and was rechartered in 1895.

CADIZ, a town of the province of Negros Occidental, island of Negros, Philippine Islands, on the N. coast, about 53 m. N.N.E. of Bacolod, the capital. Pop. (1903) 16,429. Lumber products are manufactured in the town, and a saw-mill here is said to be the largest in the Philippines.

CADIZ (Cadiz), a maritime province in the extreme south of Spain, formed in 1833 of districts taken from the province of Seville; and bounded on the N. by Seville, E. by Malaga, S.E. by the Mediterranean sea, S. by the Straits of Gibraltar, and W. by the Atlantic Ocean. Pop. (1900) 452,659; area 2834 sq. m.; inclusive, in each case, of the town and territory of Ceuta, on the Moroccan coast, which belong, for administrative purposes, to Cadiz. The sea-board of Cadiz possesses several features of exceptional interest. On the Atlantic littoral, the broad Guadalquivir estuary marks the frontier of Seville; farther south, the river Guadalete, which waters the northern districts, falls into the magnificent double bay of Cadiz; farther south again, is Cape Trafalgar, famous for the British naval victory of 1805. Near Trafalgar, the river Barbate issues into the straits of Gibraltar, after receiving several small tributaries, which combine with it to form, near its mouth, the broad and marshy Laguna de la Janda. Punta Marroqui, on the straits, is the southernmost promontory of the European mainland. The [v.04 p.0929] most conspicuous feature of the east coast is Algeciras Bay, overlooked by the rock and fortress of Gibraltar. The river Guadiaro, which drains the eastern highlands, enters the Mediterranean close to the frontier of Malaga. In the interior there is a striking contrast between the comparatively level western half of Cadiz and the very picturesque mountain ranges of the eastern half, which are well wooded and abound in game. The whole region known as the Campo de Gibraltar is of this character; but it is in the north-east that the summits are most closely massed together, and attain their greatest altitudes in the Cerro de San Cristobal (5630 ft.) and the Sierra del Pinar (5413 ft.).

The climate is generally mild and temperate, some parts of the coast only being unhealthy owing to a marshy soil. Severe drought is not unusual, and it was largely this cause, together with want of capital, and the dependence of the peasantry on farming and fishing, that brought about the distress so prevalent early in the 20th century. The manufactures are insignificant compared with the importance of the natural products of the soil, especially wines and olives. Jerez de la Frontera (Xeres) is famous for the manufacture and export of sherry. The fisheries furnish about 2500 tons of fish per annum, one-fifth part of which is salted for export and the rest consumed in Spain. There are no important mines, but a considerable amount of salt is obtained by evaporation of sea-water in pans near Cadiz, San Fernando, Puerto Real and Santa Maria. The railway from Seville passes through Jerez de la Frontera to Cadiz and San Fernando, and another line, from Granada, terminates at Algeciras; but at the beginning of the 20th century, although it was proposed to construct railways from Jerez inland to Grazalema and coastwise from San Fernando to Tarifa, travellers who wished to visit these places were compelled to use the old-fashioned diligence, over indifferent roads, or to go by sea. The principal seaports are, after Cadiz the capital (pop. 1900, 69,382), Algeciras (13,302), La Linea (31,862), Puerto de Santa Maria (20,120), Puerto Real (10,535), the naval station of San Fernando (29,635), San Lucar (23,883) and Tarifa (11,723); the principal inland towns are Arcos de la Frontera (13,926), Chiclana (10,868), Jerez de la Frontera (63,473), Medina Sidonia (11,040), and Vejer de la Frontera (11,298). These are all described in separate articles. Grazalema (5587), Jimena de la Frontera (7549), and San Roque (8569) are less important towns with some trade in leather, cork, wine and farm produce. They all contain many Moorish antiquities, and Grazalema probably represents the Roman Lacidulermium. (See also ANDALUSIA.)

CADIZ (in Lat. Gades, and formerly called Cales by the English), the capital and principal seaport of the Spanish province of Cadiz; on the Bay of Cadiz, an inlet of the Atlantic Ocean, in 36 deg. 27' N. and 6 deg. 12' W., 94 m. by rail S. of Seville. Pop. (1900) 69,382. Cadiz is built on the extremity of a tongue of land, projecting about 5 m. into the sea, in a north-westerly direction from the Isla de Leon. Its noble bay, more than 30 m. in circuit, and almost entirely land-locked by the isthmus and the headlands which lie to the north-east, has principally contributed to its commercial importance. The outer bay stretches from the promontory and town of Rota to the mouth of the river Guadalete; the inner bay, protected by the forts of Matagorda and Puntales, affords generally good anchorage, and contains a harbour formed by a projecting mole, where vessels of small burden may discharge. The entrance to the bays is rendered somewhat dangerous by the low shelving rocks (Cochinos and Las Puercas) which encumber the passage, and by the shifting banks of mud deposited by the Guadalete and the Rio Santi Petri, a broad channel separating the Isla de Leon from the mainland. At the mouth of this channel is the village of Caracca; close beside it is the important naval arsenal of San Fernando (q.v.); and on the isthmus are the defensive works known as the Cortadura, or Fort San Fernando, and the well-frequented sea-bathing establishments.

From its almost insular position Cadiz enjoys a mild and serene climate. The Medina, or land-wind, so-called because it blows from the direction of Medina Sidonia, prevails during the winter; the moisture-laden Virazon, a westerly sea-breeze, sets in with the spring. The mean annual temperature is about 64 deg. F., while the mean summer and winter temperatures vary only about 10 deg. above and below this point; but the damp atmosphere is very oppressive in summer, and its unhealthiness is enhanced by the inadequate drainage and the masses of rotting seaweed piled along the shore. The high death-rate, nearly 45 per thousand, is also due to the bad water-supply, the water being either collected in cisterns from the tops of the houses, or brought at great expense from Santa Maria on the opposite coast by an aqueduct nearly 30 m. long. An English company started a waterworks in Cadiz about 1875, but came to grief through the incapacity of the population to appreciate its necessity.

The city, which is 6 or 7 m. in circumference, is surrounded by a wall with five gates, one of which communicates with the isthmus. Seen from a distance off the coast, it presents a magnificent display of snow-white turrets rising majestically from the sea; and for the uniformity and elegance of its buildings, it must certainly be ranked as one of the finest cities of Spain, although, being hemmed in on all sides, its streets and squares are necessarily contracted. Every house annually receives a coating of whitewash, which, when it is new, produces a disagreeable glare. The city is distinguished by its somewhat deceptive air of cleanliness, its quiet streets, where no wheeled traffic passes, and its lavish use of white Italian marble. But the most characteristic feature of Cadiz is the marine promenades, fringing the city all round between the ramparts and the sea, especially that called the Alameda, on the eastern side, commanding a view of the shipping in the bay and the ports on the opposite shore. The houses are generally lofty and surmounted by turrets and flat roofs in the Moorish style.

Cadiz is the see of a bishop, who is suffragan to the archbishop of Seville, but its chief conventual and monastic institutions have been suppressed. Of its two cathedrals, one was originally erected by Alphonso X. of Castile (1252-1284), and rebuilt after 1596; the other, begun in 1722, was completed between 1832 and 1838. Under the high altar of the old cathedral rises the only freshwater spring in Cadiz. The chief secular buildings include the Hospicio, or Casa de Misericordia, adorned with a marble portico, and having an interior court with Doric colonnades; the bull-ring, with room for 12,000 spectators; the two theatres, the prison, the custom-house, and the lighthouse of San Sebastian on the western side rising 172 ft. from the rock on which it stands. Besides the Hospicio already mentioned, which sometimes contains 1000 inmates, there are numerous other charitable institutions, such as the women's hospital, the foundling institution, the admirable Hospicio de San Juan de Dios for men, and the lunatic asylum. Gratuitous instruction is given to a large number of children, and there are several mathematical and commercial academies, maintained by different commercial corporations, a nautical school, a school of design, a theological seminary and a flourishing medical school. The museum is filled for the most part with Roman and Carthaginian coins and other antiquities; the academy contains a valuable collection of pictures. In the church of Santa Catalina, which formerly belonged to the Capuchin convent, now secularized, there is an unfinished picture of the marriage of St Catherine, by Murillo, who met his death by falling from the scaffold on which he was painting it (3rd of April 1682).

Cadiz no longer ranks among the first marine cities of the world. Its harbour works are insufficient and antiquated, though a scheme for their improvement was adopted in 1903; its communications with the mainland consist of a road and a single line of railway; its inhabitants, apart from foreign residents and a few of the more enterprising merchants, rest contented with such prosperity as a fine natural harbour and an unsurpassed geographical situation cannot fail to confer. Several great shipping lines call here; shipbuilding yards and various factories exist on the mainland; and there is a considerable trade in the exportation of wine, principally sherry from Jerez, salt, olives, figs, canary-seed and ready-made corks; and in the importation of fuel, iron and machinery, building materials, American oak staves for casks, &c. In 1904, 2753 ships of 1,745,588 tons [v.04 p.0930] entered the port. But local trade, though still considerable, remains stationary if it does not actually recede. Its decline, originally due to the Napoleonic wars and the acquisition of independence by many Spanish colonies early in the 19th century, was already recognised, and an attempt made to check it in 1828, when the Spanish government declared Cadiz a free warehousing port; but this valuable privilege was withdrawn in 1832. Among the more modern causes of depression have been the rivalry of Gibraltar and Seville; the decreasing demand for sherry; and the disasters of the Spanish-American war of 1898, which almost ruined local commerce with Cuba and Porto Rico.

History.—Cadiz represents the Sem. Agadir, Gadir, or Gaddir ("stronghold") of the Carthaginians, the Gr. Gadeira, and the Lat. Gades. Tradition ascribes its foundation to Phoenician merchants from Tyre, as early as 1100 B.C.; and in the 7th century it had already become the great mart of the west for amber and tin from the Cassiterides (q.v.). About 501 B.C. it was occupied by the Carthaginians, who made it their base for the conquest of southern Iberia, and in the 3rd century for the equipment of the armaments with which Hannibal undertook to destroy the power of Rome. But the loyalty of Gades, already weakened by trade rivalry with Carthage, gave way after the second Punic War. Its citizens welcomed the victorious Romans, and assisted them in turn to fit out an expedition against Carthage. Thenceforward, its rapidly-growing trade in dried fish and meat, and in all the produce of the fertile Baetis (Guadalquivir) valley, attracted many Greek settlers; while men of learning, such as Pytheas in the 4th century B.C., Polybius and Artemidorus of Ephesus in the 2nd, and Posidonius in the 1st, came to study the ebb and flow of its tides, unparalleled in the Mediterranean. C. Julius Caesar conferred the civitas of Rome on all its citizens in 49 B.C.; and, not long after L. Cornelius Balbus Minor built what was called the "New City," constructed the harbour which is now known as Puerto Real, and spanned the strait of Santi Petri with the bridge which unites the Isla de Leon with the mainland, and is now known as the Puente de Zuazo, after Juan Sanchez de Zuazo, who restored it in the 15th century. Under Augustus, when it was the residence of no fewer than 500 equites, a total only surpassed in Rome and Padua, Gades was made a municipium with the name of Augusta Urbs Gaditana, and its citizens ranked next to those of Rome. In the 1st century A.D. it was the birthplace or home of several famous authors, including Lucius Columella, poet and writer on husbandry; but it was more renowned for gaiety and luxury than for learning. Juvenal and Martial write of Jocosae Gades, "Cadiz the Joyous," as naturally as the modern Andalusian speaks of Cadiz la Joyosa; and throughout the Roman world its cookery and its dancing-girls were famous. In the 5th century, however, the overthrow of Roman dominion in Spain by the Visigoths involved Cadiz in destruction. A few fragments of masonry, submerged under the sea, are almost all that remains of the original city. Moorish rule over the port, which was renamed Jezirat-Kadis, lasted from 711 until 1262, when Cadiz was captured, rebuilt and repeopled by Alphonso X. of Castile. Its renewed prosperity dates from the discovery of America in 1492. As the headquarters of the Spanish treasure fleets, it soon recovered its position as the wealthiest port of western Europe, and consequently it was a favourite point of attack for the enemies of Spain. During the 16th century it repelled a series of raids by the Barbary corsairs; in 1587 all the shipping in its harbour was burned by the English squadron under Sir Francis Drake; in 1596 the fleet of the earl of Essex and Lord Charles Howard sacked the city, and destroyed forty merchant vessels and thirteen warships. This disaster necessitated the rebuilding of Cadiz on a new plan. Its recovered wealth tempted the duke of Buckingham to promote the fruitless expedition to Cadiz of 1626; thirty years later Admiral Blake blockaded the harbour in an endeavour to intercept the treasure fleet; and in 1702 another attack was made by the British under Sir George Rooke and the duke of Ormonde. During the 18th century the wealth of Cadiz became greater than ever; from 1720 to 1765, when it enjoyed a monopoly of the trade with Spanish America, the city annually imported gold and silver to the value of about L5,000,000. With the closing years of the century, however, it entered upon a period of misfortune. From February 1797 to April 1798 it was blockaded by the British fleet, after the battle of Cape St Vincent; and in 1800 it was bombarded by Nelson. In 1808 the citizens captured a French squadron which was imprisoned by the British fleet in the inner bay. From February 1810 until the duke of Wellington raised the siege in August 1812, Cadiz resisted the French forces sent to capture it; and during these two years it served as the capital of all Spain which could escape annexation by Napoleon. Here, too, the Cortes met and promulgated the famous Liberal constitution of March 1812. To secure a renewal of this constitution, the citizens revolted in 1820; the revolution spread throughout Spain; the king, Ferdinand VII., was imprisoned at Cadiz, which again became the seat of the Cortes; and foreign intervention alone checked the movement towards reform. A French army, under the duc d'Angouleme, seized Cadiz in 1823, secured the release of Ferdinand and suppressed Liberalism. In 1868 the city was the centre of the revolution which effected the dethronement of Queen Isabella.

CADMIUM (symbol Cd, atomic weight 112.4 (O=16)), a metallic element, showing a close relationship to zinc, with which it is very frequently associated. It was discovered in 1817 by F. Stromeyer in a sample of zinc carbonate from which a specimen of zinc oxide was obtained, having a yellow colour, although quite free from iron; Stromeyer showing that this coloration was due to the presence of the oxide of a new metal. Simultaneously Hermann, a German chemical manufacturer, discovered the new metal in a specimen of zinc oxide which had been thought to contain arsenic, since it gave a yellow precipitate, in acid solution, on the addition of sulphuretted hydrogen. This supposition was shown to be incorrect, and the nature of the new element was ascertained.

Cadmium does not occur naturally in the uncombined condition, and only one mineral is known which contains it in any appreciable quantity, namely, greenockite, or cadmium sulphide, found at Greenock and at Bishopton in Scotland, and in Bohemia and Pennsylvania. It is, however, nearly always found associated with zinc blende, and with calamine, although only in small quantities.

The metal is usually obtained from the flue-dust (produced during the first three or four hours working of a zinc distillation) which is collected in the sheet iron cones or adapters of the zinc retorts. This is mixed with small coal, and when redistilled gives an enriched dust, and by repeating the process and distilling from cast iron retorts the metal is obtained. It can be purified by solution in hydrochloric acid and subsequent precipitation by metallic zinc.

Cadmium is a white metal, possessing a bluish tinge, and is capable of taking a high polish; on breaking, it shows a distinct fibrous fracture. By sublimation in a current of hydrogen it can be crystallized in the form of regular octahedra; it is slightly harder than tin, but is softer than zinc, and like tin, emits a crackling sound when bent. It is malleable and can be rolled out into sheets. The specific gravity of the metal is 8.564, this value being slightly increased after hammering; its specific heat is 0.0548 (R. Bunsen), it melts at 310-320 deg. C. and boils between 763-772 deg. C. (T. Carnelley), forming a deep yellow vapour. The cadmium molecule, as shown by determinations of the density of its vapour, is monatomic. The metal unites with the majority of the heavy metals to form alloys; some of these, the so-called fusible alloys, find a useful application from the fact that they possess a low melting-point. It also forms amalgams with mercury, and on this account has been employed in dentistry for the purpose of stopping (or filling) [v.04 p.0931] teeth. The metal is quite permanent in dry air, but in moist air it becomes coated with a superficial layer of the oxide; it burns on heating to redness, forming a brown coloured oxide; and is readily soluble in mineral acids with formation of the corresponding salts. Cadmium vapour decomposes water at a red heat, with liberation of hydrogen, and formation of the oxide of the metal.

Cadmium oxide, CdO, is a brown powder of specific gravity 6.5, which can be prepared by heating the metal in air or in oxygen; or by ignition of the nitrate or carbonate; by heating the metal to a white heat in a current of oxygen it is obtained as a dark red crystalline sublimate. It does not melt at a white heat, and is easily reduced to the metal by heating in a current of hydrogen or with carbon. It is a basic oxide, dissolving readily in acids, with the formation of salts, somewhat analogous to those of zinc.

Cadmium hydroxide, Cd(OH)_2, is obtained as a white precipitate by adding potassium hydroxide to a solution of any soluble cadmium salt. It is decomposed by heat into the oxide and water, and is soluble in ammonia but not in excess of dilute potassium hydroxide; this latter property serves to distinguish it from zinc hydroxide.

The chloride, CdCl_2, bromide, CdBr_2, and iodide, CdI_2, are also known, cadmium iodide being sometimes used in photography, as it is one of the few iodides which are soluble in alcohol. Cadmium chloride and iodide have been shown to behave in an anomalous way in aqueous solution (W. Hittorf, _Pogg. Ann._, 1859, 106, 513), probably owing to the formation of complex ions; the abnormal behaviour apparently diminishing as the solution becomes more and more dilute, until, at very high dilutions the salts are ionized in the normal manner.

Cadmium sulphate, CdSO_4, is known in several hydrated forms; being deposited, on spontaneous evaporation of a concentrated aqueous solution, in the form of large monosymmetric crystals of composition 3CdSO_4.8H_2O, whilst a boiling saturated solution, to which concentrated sulphuric acid has been added, deposits crystals of composition CdSO_4.H_2O. It is largely used for the purpose of making standard electric cells, such for example as the Weston cell.

Cadmium sulphide, CdS, occurs naturally as greenockite (q.v.), and can be artificially prepared by passing sulphuretted hydrogen through acid solutions of soluble cadmium salts, when it is precipitated as a pale yellow amorphous solid. It is used as a pigment (cadmium yellow), for it retains its colour in an atmosphere containing sulphuretted hydrogen; it melts at a white heat, and on cooling solidifies to a lemon-yellow micaceous mass.

Normal cadmium carbonates are unknown, a white precipitate of variable composition being obtained on the addition of solutions of the alkaline carbonates to soluble cadmium salts.

Cadmium nitrate, Cd(NO_3)_2.4H_2O, is a deliquescent salt, which may be obtained by dissolving either the metal, or its oxide or carbonate in dilute nitric acid. It crystallizes in needles and is soluble in alcohol.

Cadmium salts can be recognized by the brown incrustation which is formed when they are heated on charcoal in the oxidizing flame of the blowpipe; and also by the yellow precipitate formed when sulphuretted hydrogen is passed though their acidified solutions. This precipitate is insoluble in cold dilute acids, in ammonium sulphide, and in solutions of the caustic alkalis, a behaviour which distinguishes it from the yellow sulphides of arsenic and tin. Cadmium is estimated quantitatively by conversion into the oxide, being precipitated from boiling solutions by the addition of sodium carbonate, the carbonate thus formed passing into the oxide on ignition. It can also be determined as sulphide, by precipitation with sulphuretted hydrogen, the precipitated sulphide being dried at 100 deg. C. and weighed.

The atomic weight of cadmium was found by O.W. Huntington (Berichte, 1882, 15, p. 80), from an analysis of the pure bromide, to be 111.9. H.N. Morse and H.C. Jones (Amer. Chem. Journ., 1892, 14, p. 261) by conversion of cadmium into the oxalate and then into oxide, obtained values ranging from 111.981 to 112.05, whilst W.S. Lorimer and E.F. Smith (Zeit. fuer anorg. Chem., 1891, 1, p. 364), by the electrolytic reduction of cadmium oxide in potassium cyanide solution, obtained as a mean value 112.055. The atomic weight of cadmium has been revised by G.P. Baxter and M.A. Hines (Journ. Amer. Chem. Soc., 1905, 27, p. 222), by determinations of the ratio of cadmium chloride to silver chloride, and of the amount of silver required to precipitate cadmium chloride. The mean value obtained was 112.469 (Ag=107.93). The mean value 112.467 was obtained by Baxter, Hines and Frevert (ibid., 1906, 28, p. 770) by analysing cadmium bromide.

CADMUS, in Greek legend, son of Agenor, king of Phoenicia and brother of Europa. After his sister had been carried off by Zeus, he was sent out to find her. Unsuccessful in his search, he came in the course of his wanderings to Delphi, where he consulted the oracle. He was ordered to give up his quest and follow a cow which would meet him, and to build a town on the spot where she should lie down exhausted. The cow met him in Phocis, and guided him to Boeotia, where he founded the city of Thebes. Intending to sacrifice the cow, he sent some of his companions to a neighbouring spring for water. They were slain by a dragon, which was in turn destroyed by Cadmus; and by the instructions of Athena he sowed its teeth in the ground, from which there sprang a race of fierce armed men, called Sparti (sown). By throwing a stone among them Cadmus caused them to fall upon each other till only five survived, who assisted him to build the Cadmeia or citadel of Thebes and became the founders of the noblest families of that city (Ovid, Metam. iii. 1 ff.; Apollodorus iii. 4, 5). Cadmus, however, because of this bloodshed, had to do penance for eight years. At the expiration of this period the gods gave him to wife Harmonia (q.v.), daughter of Ares and Aphrodite, by whom he had a son Polydorus, and four daughters, Ino, Autonoe, Agave and Semele—a family which was overtaken by grievous misfortunes. At the marriage all the gods were present; Harmonia received as bridal gifts a peplos worked by Athena and a necklace made by Hephaestus. Cadmus is said to have finally retired with Harmonia to Illyria, where he became king. After death, he and his wife were changed into snakes, which watched the tomb while their souls were translated to the Elysian fields.

There is little doubt that Cadmus was originally a Boeotian, that is, a Greek hero. In later times the story of a Phoenician immigrant of that name became current, to whom was ascribed the introduction of the alphabet, the invention of agriculture and working in bronze and of civilization generally. But the name itself is Greek rather than Phoenician; and the fact that Hermes was worshipped in Samothrace under the name of Cadmus or Cadmilus seems to show that the Theban Cadmus was originally an ancestral Theban hero corresponding to the Samothracian. The name may mean "order," and be used to characterize one who introduces order and civilization.

The exhaustive article by O. Crusius in W.H. Roscher's Lexikon der Mythologie contains a list of modern authorities on the subject of Cadmus; see also O. Gruppe, De Cadmi Fabula (1891).

CADMUS OF MILETUS, according to some ancient authorities the oldest of the logographi (q.v.). Modern scholars, who accept this view, assign him to about 550 B.C.; others regard him as purely mythical. A confused notice in Suidas mentions three persons of the name: the first, the inventor of the alphabet; the second, the son of Pandion, "according to some" the first prose writer, a little later than Orpheus, author of a history of the Foundation of Miletus and of Ionia generally, in four books; the third, the son of Archelaus, of later date, author of a history of Attica in fourteen books, and of some poems of an erotic character. As Dionysius of Halicarnassus (Judicium de Thucydide, c. 23) distinctly states that the work current in his time under the name of Cadmus was a forgery, it is most probable that the two first are identical with the Phoenician Cadmus, who, as the reputed inventor of letters, was subsequently transformed into the Milesian and the author of an historical work. In this connexion it should be observed that the old Milesian nobles traced their descent back to the Phoenician or one of his companions. The text of the notice of the third Cadmus of Miletus in Suidas is unsatisfactory; and it is uncertain whether he is to be explained in the same way, or whether he was an historical personage, of whom all further record is lost.

CADOGAN, WILLIAM CADOGAN, 1ST EARL (1675-1726), British soldier, was the son of Henry Cadogan, a Dublin barrister, and grandson of Major William Cadogan (1601-1661), governor of Trim. The family has been credited with a descent from Cadwgan, the old Welsh prince. Cadogan began his military career as a cornet of horse under William III. at the Boyne, and, with the regiment now known as the 5th (Royal Irish) Lancers, made the campaigns in the Low Countries. In the course of these years he attracted the notice of Marlborough. In 1701 Cadogan was employed by him as a staff officer in the complicated task of concentrating the grand army formed by contingents from [v.04 p.0932] multitudinous states, and Marlborough soon made the young officer his confidential staff officer and right-hand man. His services in the campaign of 1701 were rewarded with the colonelcy of the famous "Cadogan's Horse" (now the 5th Dragoon Guards). As quartermaster-general, it fell to his lot to organize the celebrated march of the allies to the Danube, which, as well as the return march with its heavy convoys, he managed with consummate skill. At the Schellenberg he was wounded and his horse shot under him, and at Blenheim he acted as Marlborough's chief of staff. Soon afterwards he was promoted brigadier-general, and in 1705 he led "Cadogan's Horse" at the forcing of the Brabant lines between Wange and Elissem, capturing four standards. He was present at Ramillies, and immediately afterwards was sent to take Antwerp, which he did without difficulty. Becoming major-general in 1706, he continued to perform the numerous duties of chief staff officer, quartermaster-general and colonel of cavalry, besides which he was throughout constantly employed in delicate diplomatic missions. In the course of the campaign of 1707, when leading a foraging expedition, he fell into the hands of the enemy but was soon exchanged. In 1708 he commanded the advanced guard of the army in the operations which culminated in the victory of Oudenarde, and in the same year he was with Webb at the action of Wynendael. On the 1st of January 1709 he was made lieutenant-general. At the siege of Menin in this year occurred an incident which well illustrates his qualifications as a staff officer and diplomatist. Marlborough, riding with his staff close to the French, suddenly dropped his glove and told Cadogan to pick it up. This seemingly insolent command was carried out at once, and when Marlborough on the return to camp explained that he wished a battery to be erected on the spot, Cadogan informed him that he had already given orders to that effect. He was present at Malplaquet, and after the battle was sent off to form the siege of Mons, at which he was dangerously wounded. At the end of the year he received the appointment of lieutenant of the Tower, but he continued with the army in Flanders to the end of the war. His loyalty to the fallen Marlborough cost him, in 1712, his rank, positions and emoluments under the crown. George I. on his accession, however, reinstated Cadogan, and, amongst other appointments, made him lieutenant of the ordnance. In 1715, as British plenipotentiary, he signed the third Barrier Treaty between Great Britain, Holland and the emperor. His last campaign was the Jacobite insurrection of 1715-1716. At first as Argyle's subordinate (see Coxe, Memoirs of Marlborough, cap. cxiv.), and later as commander-in-chief, General Cadogan by his firm, energetic and skilful handling of his task restored quiet and order in Scotland. Up to the death of Marlborough he was continually employed in diplomatic posts of special trust, and in 1718 he was made Earl Cadogan, Viscount Caversham and Baron Cadogan of Oakley. In 1722 he succeeded his old chief as head of the army and master-general of the ordnance, becoming at the same time colonel of the 1st or Grenadier Guards. He sat in five successive parliaments as member for Woodstock. He died at Kensington in 1726, leaving two daughters, one of whom married the second duke of Richmond and the other the second son of William earl of Portland.

Readers of Esmond will have formed a very unfavourable estimate of Cadogan, and it should be remembered that Thackeray's hero was the friend and supporter of the opposition and General Webb. As a soldier, Cadogan was one of the best staff officers in the annals of the British army, and in command of detachments, and also as a commander-in-chief, he showed himself to be an able, careful and withal dashing leader.

He was succeeded, by special remainder, in the barony by his brother, General Charles Cadogan (1691-1776), who married the daughter of Sir Hans Sloane, thus beginning the association of the family with Chelsea, and died in 1776, being succeeded in turn by his son Charles Sloane (1728-1807), who in the year 1800 was created Viscount Chelsea and Earl Cadogan. His descendant George Henry, 5th Earl Cadogan (b. 1840), was lord privy seal from 1886 to 1892, and lord-lieutenant of Ireland from 1895 to 1902.

CADOUDAL, GEORGES (1771-1804), leader of the Chouans during the French Revolution, was born in 1771 near Auray. He had received a fair education, and when the Revolution broke out he remained true to his royalist and Catholic teaching. From 1793 he organized a rebellion in the Morbihan against the revolutionary government. It was quickly suppressed and he thereupon joined the army of the revolted Vendeans, taking part in the battles of Le Mans and of Savenay in December 1793. Returning to Morbihan, he was arrested, and imprisoned at Brest. He succeeded, however, in escaping, and began again the struggle against the Revolution. In spite of the defeat of his party, and of the fact that he was forced several times to take refuge in England, Cadoudal did not cease both to wage war and to conspire in favour of the royalist pretenders. He refused to come to any understanding with the government, although offers were made to him by Bonaparte, who admired his skill and his obstinate energy. From 1800 it was impossible for Cadoudal to continue to wage open war, so he took altogether to plotting. He was indirectly concerned in the attempt made by Saint Regent in the rue Sainte Nicaise on the life of the First Consul, in December 1800, and fled to England again. In 1803 he returned to France to undertake a new attempt against Bonaparte. Though watched for by the police, he succeeded in eluding them for six months, but was at length arrested. Found guilty and condemned to death, he refused to ask for pardon and was executed in Paris on the 10th of June 1804, along with eleven of his companions. He is often called simply Georges.

CADRE (Fr. for a frame, from the Lat. quadrum, a square), a framework or skeleton, particularly the permanent establishment of a military corps, regiment, &c. which can be expanded on emergency.

CADUCEUS (the Lat. adaptation of the Doric Gr. [Greek: karukeion], Attic [Greek: kerukeion], a herald's wand), the staff used by the messengers of the gods, and especially by Hermes as conductor of the souls of the dead to the world below. The caduceus of Hermes, which was given him by Apollo in exchange for the lyre, was a magic wand which exercised influence over the living and the dead, bestowed wealth and prosperity and turned everything it touched into gold. In its oldest form it was a rod ending in two prongs twined into a knot (probably an olive branch with two shoots, adorned with ribbons or garlands), for which, later, two serpents, with heads meeting at the top, were substituted. The mythologists explained this by the story of Hermes finding two serpents thus knotted together while fighting; he separated them with his wand, which, crowned by the serpents, became the symbol of the settlement of quarrels (Thucydides i. 53; Macrobius, Sat. i. 19; Hyginus, Poet. Astron. ii. 7). A pair of wings was sometimes attached to the top of the staff, in token of the speed of Hermes as a messenger. In historical times the caduceus was the attribute of Hermes as the god of commerce and peace, and among the Greeks it was the distinctive mark of heralds and ambassadors, whose persons it rendered inviolable. The caduceus itself was not used by the Romans, but the derivative caduceator occurs in the sense of a peace commissioner.

See L. Preller, "Der Hermesstab" in Philologus, i. (1846); O.A. Hoffmann, Hermes und Kerykeion (1890), who argues that Hermes is a male lunar divinity and his staff the special attribute of Aphrodite-Astarte.

CADUCOUS (Lat. caducus), a botanical term for "falling early," as the sepals of a poppy, before the petals expand.

CAECILIA. This name was given by Linnaeus to the blind, or nearly blind, worm-like Batrachians which were formerly associated with the snakes and are now classed as an order under the names of Apoda, Peromela or Gymnophiona. The type of the genus Caecilia is Caecilia tentaculata, a moderately slender species, not unlike a huge earth-worm, growing to 2 ft. in length with a diameter of three-quarters of an inch. It is one of the largest species of the order. Other species of the same genus are very slender in form, as for instance Caecilia gracilis, [v.04 p.0933] which with a length of 21/4 ft. has a diameter of only a quarter of an inch. One of the most remarkable characters of the genus Caecilia, which it shares with about two-thirds of the known genera of the order, is the presence of thin, cycloid, imbricate scales imbedded in the skin, a character only to be detected by raising the epidermis near the dermal folds, which more or less completely encircle the body. This feature, unique among living Batrachians, is probably directly inherited from the scaly Stegocephalia, a view which is further strengthened by the similarity of structure of these scales in both groups, which the histological investigations of H. Credner have revealed. The skull is well ossified and contains a greater number of bones than occur in any other living Batrachian. There is therefore strong reason for tracing the Caecilians directly from the Stegocephalia, as was the view of T.H. Huxley and of R. Wiedersheim, since supported by H. Gadow and by J.S. Kingsley. E.D. Cope had advocated the abolition of the order Apoda and the incorporation of the Caecilians among the Urodela or Caudata in the vicinity of the Amphiumidae, of which he regarded them as further degraded descendants; and this opinion, which was supported by very feeble and partly erroneous arguments, has unfortunately received the support of the two great authorities, P. and F. Sarasin, to whom we are indebted for our first information on the breeding habits and development of these Batrachians.
