You will not accuse me of underrating your accomplishments. You know what to do for a child in a fit, for an alderman in an apoplexy, for a girl that has fainted, for a woman in hysterics, for a leg that is broken, for an arm that is out of joint, for fevers of every color, for the sailor's rheumatism, and the tailor's cachexy. In fact you do really know so much at this very hour, that nothing but the searching test of time can fully teach you the limitations of your knowledge.

Of some of these you will permit me to remind you. You will never have outgrown the possibility of new acquisitions, for Nature is endless in her variety. But even the knowledge which you may be said to possess will be a different thing after long habit has made it a part of your existence. The tactus eruditus extends to the mind as well as to the finger-ends. Experience means the knowledge gained by habitual trial, and an expert is one who has been in the habit of trying. This is the kind of knowledge that made Ulysses wise in the ways of men. Many cities had he seen, and known the minds of those who dwelt in them. This knowledge it was that Chaucer's Shipman brought home with him from the sea—

"In many a tempest had his berd be shake."

This is the knowledge we place most confidence in, in the practical affairs of life.

Our training has two stages. The first stage deals with our intelligence, which takes the idea of what is to be done with the most charming ease and readiness. Let it be a game of billiards, for instance, which the marker is going to teach us. We have nothing to do but to make this ball glance from that ball and hit that other ball, and to knock that ball with this ball into a certain caecal sacculus or diverticulum which our professional friend calls a pocket. Nothing can be clearer; it is as easy as "playing upon this pipe," for which Hamlet gives Guildenstern such lucid directions. But this intelligent Me, who steps forward as the senior partner in our dual personality, turns out to be a terrible bungler. He misses those glancing hits which the hard-featured young professional person calls "carroms," and insists on pocketing his own ball instead of the other one.

It is the unintelligent Me, stupid as an idiot, that has to try a thing a thousand times before he can do it, and then never knows how he does it, that at last does it well. We have to educate ourselves through the pretentious claims of intellect, into the humble accuracy of instinct, and we end at last by acquiring the dexterity, the perfection, the certainty, which those masters of arts, the bee and the spider, inherit from Nature.

Book-knowledge, lecture-knowledge, examination-knowledge, are all in the brain. But work-knowledge is not only in the brain, it is in the senses, in the muscles, in the ganglia of the sympathetic nerves,—all over the man, as one may say, as instinct seems diffused through every part of those lower animals that have no such distinct organ as a brain. See a skilful surgeon handle a broken limb; see a wise old physician smile away a case that looks to a novice as if the sexton would soon be sent for; mark what a large experience has done for those who were fitted to profit by it, and you will feel convinced that, much as you know, something is still left for you to learn.

May I venture to contrast youth and experience in medical practice, something in the way the man painted the lion, that is, the lion under?

The young man knows the rules, but the old man knows-the exceptions. The young man knows his patient, but the old man knows also his patient's family, dead and alive, up and down for generations. He can tell beforehand what diseases their unborn children will be subject to, what they will die of if they live long enough, and whether they had better live at all, or remain unrealized possibilities, as belonging to a stock not worth being perpetuated. The young man feels uneasy if he is not continually doing something to stir up his patient's internal arrangements. The old man takes things more quietly, and is much more willing to let well enough alone: All these superiorities, if such they are,'you must wait for time to bring you. In the meanwhile (if we will let the lion be uppermost for a moment), the young man's senses are quicker than those of his older rival. His education in all the accessory branches is more recent, and therefore nearer the existing condition of knowledge. He finds it easier than his seniors to accept the improvements which every year is bringing forward. New ideas build their nests in young men's brains. "Revolutions are not made by men in spectacles," as I once heard it remarked, and the first whispers of a new truth are not caught by those who begin to feel the need of an ear-trumpet. Granting all these advantages to the young man, he ought, nevertheless, to go on improving, on the whole, as a medical practitioner, with every year, until he has ripened into a well-mellowed maturity. But, to improve, he must be good for something at the start. If you ship a poor cask of wine to India and back, if you keep it a half a century, it only grows thinner and sharper.

You are soon to enter into relations with the public, to expend your skill and knowledge for its benefit, and find your support in the rewards of your labor. What kind of a constituency is this which is to look to you as its authorized champions in the struggle of life against its numerous enemies?

In the first place, the persons who seek the aid of the physician are very honest and sincere in their wish to get rid of their complaints, and, generally speaking, to live as long as they can. However attractively the future is painted to them, they are attached to the planet with which they are already acquainted. They are addicted to the daily use of this empirical and unchemical mixture which we call air; and would hold on to it as a tippler does to his alcoholic drinks. There is nothing men will not do, there is nothing they have not done, to recover their health and save their lives. They have submitted to be half-drowned in water, and half-choked with gases, to be buried up to their chins in earth, to be seared with hot irons like galley-slaves, to be crimped with knives, like cod-fish, to have needles thrust into their flesh, and bonfires kindled on their skin, to swallow all sorts of abominations, and to pay for all this, as if to be singed and scalded were a costly privilege, as if blisters were a blessing, and leeches were a luxury. What more can be asked to prove their honesty and sincerity?

This same community is very intelligent with respect to a great many subjects-commerce, mechanics, manufactures, politics. But with regard to medicine it is hopelessly ignorant and never finds it out. I do not know that it is any worse in this country than in Great Britain, where Mr. Huxley speaks very freely of "the utter ignorance of the simplest laws of their own animal life, which prevails among even the most highly educated persons." And Cullen said before him "Neither the acutest genius nor the soundest judgment will avail in judging of a particular science, in regard to which they have not been exercised. I have been obliged to please my patients sometimes with reasons, and I have found that any will pass, even with able divines and acute lawyers; the same will pass with the husbands as with the wives." If the community could only be made aware of its own utter ignorance, and incompetence to form opinions on medical subjects, difficult enough to those who give their lives to the study of them, the practitioner would have an easier task. But it will form opinions of its own, it cannot help it, and we cannot blame it, even though we know how slight and deceptive are their foundations.

This is the way it happens: Every grown-up person has either been ill himself or had a friend suffer from illness, from which he has recovered. Every sick person has done something or other by somebody's advice, or of his own accord, a little before getting better. There is an irresistible tendency to associate the thing done, and the improvement which followed it, as cause and effect. This is the great source of fallacy in medical practice. But the physician has some chance of correcting his hasty inference. He thinks his prescription cured a single case of a particular complaint; he tries it in twenty similar cases without effect, and sets down the first as probably nothing more than a coincidence. The unprofessional experimenter or observer has no large experience to correct his hasty generalization. He wants to believe that the means he employed effected his cure. He feels grateful to the person who advised it, he loves to praise the pill or potion which helped him, and he has a kind of monumental pride in himself as a living testimony to its efficacy. So it is that you will find the community in which you live, be it in town or country, full of brands plucked from the burning, as they believe, by some agency which, with your better training, you feel reasonably confident had nothing to do with it. Their disease went out of itself, and the stream from the medical fire-annihilator had never even touched it.

You cannot and need not expect to disturb the public in the possession of its medical superstitions. A man's ignorance is as much his private property, and as precious in his own eyes, as his family Bible. You have only to open your own Bible at the ninth chapter of St. John's Gospel, and you will find that the logic of a restored patient was very simple then, as it is now, and very hard to deal with. My clerical friends will forgive me for poaching on their sacred territory, in return for an occasional raid upon the medical domain of which they have now and then been accused.

A blind man was said to have been restored to sight by a young person whom the learned doctors of the Jewish law considered a sinner, and, as such, very unlikely to have been endowed with a divine gift of healing. They visited the patient repeatedly, and evidently teased him with their questions about the treatment, and their insinuations about the young man, until he lost his temper. At last he turned sharply upon them: "Whether he be a sinner or no, I know not: one thing I know, that, whereas I was blind, now I see."

This is the answer that always has been and always will be given by most persons when they find themselves getting well after doing anything, no matter what,—recommended by anybody, no matter whom. Lord Bacon, Robert Boyle, Bishop Berkeley, all put their faith in panaceas which we should laugh to scorn. They had seen people get well after using them. Are we any wiser than those great men? Two years ago, in a lecture before the Massachusetts Historical Society, I mentioned this recipe of Sir Kenelm Digby for fever and ague: Pare the patient's nails; put the parings in a little bag, and hang the bag round the neck of a live eel, and place him in a tub of water. The eel will die, and the patient will recover.

Referring to this prescription in the course of the same lecture, I said: "You smiled when I related Sir Kenehn Digby's prescription, with the live eel in it; but if each of you were to empty his or her pockets, would there not roll out, from more than one of them, a horse-chestnut, carried about as a cure for rheumatism?" Nobody saw fit to empty his or her pockets, and my question brought no response. But two months ago I was in a company of educated persons, college graduates every one of them, when a gentleman, well known in our community, a man of superior ability and strong common-sense, on the occasion of some talk arising about rheumatism, took a couple of very shiny horse-chestnuts from his breeches-pocket, and laid them on the table, telling us how, having suffered from the complaint in question, he had, by the advice of a friend, procured these two horse-chestnuts on a certain time a year or more ago, and carried them about him ever since; from which very day he had been entirely free from rheumatism.

This argument, from what looks like cause and effect, whether it be so or not, is what you will have to meet wherever you go, and you need not think you can answer it. In the natural course of things some thousands of persons must be getting well or better of slight attacks of colds, of rheumatic pains, every week, in this city alone. Hundreds of them do something or other in the way of remedy, by medical or other advice, or of their own motion, and the last thing they do gets the credit of the recovery. Think what a crop of remedies this must furnish, if it were all harvested!

Experience has taught, or will teach you, that most of the wonderful stories patients and others tell of sudden and signal cures are like Owen Glendower's story of the portents that announced his birth. The earth shook at your nativity, did it? Very likely, and

"So it would have done, At the same season, if your mother's cat Had kittened, though yourself had ne'er been born."

You must listen more meekly than Hotspur did to the babbling Welshman, for ignorance is a solemn and sacred fact, and, like infancy, which it resembles, should be respected. Once in a while you will have a patient of sense, born with the gift of observation, from whom you may learn something. When you find yourself in the presence of one who is fertile of medical opinions, and affluent in stories of marvellous cures,—of a member of Congress whose name figures in certificates to the value of patent medicines, of a voluble dame who discourses on the miracles she has wrought or seen wrought with the little jokers of the sugar-of-milk globule-box, take out your watch and count the pulse; also note the time of day, and charge the price of a visit for every extra fifteen, or, if you are not very busy, every twenty minutes. In this way you will turn what seems a serious dispensation into a double blessing, for this class of patients loves dearly to talk, and it does them a deal of good, and you feel as if you had earned your money by the dose you have taken, quite as honestly as by any dose you may have ordered.

You must take the community just as it is, and make the best of it. You wish to obtain its confidence; there is a short rule for doing this which you will find useful,—deserve it. But, to deserve it in full measure, you must unite many excellences, natural and acquired.

As the basis of all the rest, you must have all those traits of character which fit you to enter into the most intimate and confidential relations with the families of which you are the privileged friend and counsellor. Medical Christianity, if I may use such a term, is of very early date. By the oath of Hippocrates, the practitioner of ancient times bound himself to enter his patient's house with the sole purpose of doing him good, and so to conduct himself as to avoid the very appearance of evil. Let the physician of to-day begin by coming up to this standard, and add to it all the more recently discovered virtues and graces.

A certain amount of natural ability is requisite to make you a good physician, but by no means that disproportionate development of some special faculty which goes by the name of genius. A just balance of the mental powers is a great deal more likely to be useful than any single talent, even were it the power of observation; in excess. For a mere observer is liable to be too fond of facts for their own sake, so that, if he told the real truth, he would confess that he takes more pleasure in a post-mortem examination which shows him what was the matter with a patient, than in a case which insists on getting well and leaving him in the dark as to its nature. Far more likely to interfere with the sound practical balance of the mind is that speculative, theoretical tendency which has made so many men noted in their day, whose fame has passed away with their dissolving theories. Read Dr. Bartlett's comparison of the famous Benjamin Rush with his modest fellow-townsman Dr. William Currie, and see the dangers into which a passion for grandiose generalizations betrayed a man of many admirable qualities.

I warn you against all ambitious aspirations outside of your profession. Medicine is the most difficult of sciences and the most laborious of arts. It will task all your powers of body and mind if you are faithful to it. Do not dabble in the muddy sewer of politics, nor linger by the enchanted streams of literature, nor dig in far-off fields for the hidden waters of alien sciences. The great practitioners are generally those who concentrate all their powers on their business. If there are here and there brilliant exceptions, it is only in virtue of extraordinary gifts, and industry to which very few are equal.

To get business a man mast really want it; and do you suppose that when you are in the middle of a heated caucus, or half-way through a delicate analysis, or in the spasm of an unfinished ode, your eyes rolling in the fine frenzy of poetical composition, you want to be called to a teething infant, or an ancient person groaning under the griefs of a lumbago? I think I have known more than one young man whose doctor's sign proclaimed his readiness to serve mankind in that capacity, but who hated the sound of a patient's knock, and as he sat with his book or his microscope, felt exactly as the old party expressed himself in my friend Mr. Brownell's poem—

"All I axes is, let me alone."

The community soon finds out whether you are in earnest, and really mean business, or whether you are one of those diplomaed dilettanti who like the amusement of quasi medical studies, but have no idea of wasting their precious time in putting their knowledge in practice for the benefit of their suffering fellow-creatures.

The public is a very incompetent judge of your skill and knowledge, but it gives its confidence most readily to those who stand well with their professional brethren, whom they call upon when they themselves or their families are sick, whom they choose to honorable offices, whose writings and teachings they hold in esteem. A man may be much valued by the profession and yet have defects which prevent his becoming a favorite practitioner, but no popularity can be depended upon as permanent which is not sanctioned by the judgment of professional experts, and with these you will always stand on your substantial merits.

What shall I say of the personal habits you must form if you wish for success? Temperance is first upon the list. Intemperance in a physician partakes of the guilt of homicide, for the muddled brain may easily make a fatal blunder in a prescription and the unsteady hand transfix an artery in an operation. Tippling doctors have been too common in the history of medicine. Paracelsus was a sot, Radcliffe was much too fond of his glass, and Dr. James Hurlbut of Wethersfield, Connecticut, a famous man in his time, used to drink a square bottle of rum a day, with a corresponding allowance of opium to help steady his nerves. We commonly speak of a man as being the worse for liquor, but I was asking an Irish laborer one day about his doctor, who, as he said, was somewhat given to drink. "I like him best when he's a little that way," he said; "then I can spake to him." I pitied the poor patient who could not venture to allude to his colic or his pleurisy until his physician was tipsy.

There are personal habits of less gravity than the one I have mentioned which it is well to guard against, or, if they are formed, to relinquish. A man who may be called at a moment's warning into the fragrant boudoir of suffering loveliness should not unsweeten its atmosphere with reminiscences of extinguished meerschaums. He should remember that the sick are sensitive and fastidious, that they love the sweet odors and the pure tints of flowers, and if his presence is not like the breath of the rose, if his hands are not like the leaf of the lily, his visit may be unwelcome, and if he looks behind him he may see a window thrown open after he has left the sick-chamber. I remember too well the old doctor who sometimes came to help me through those inward griefs to which childhood is liable. "Far off his coming "—shall I say "shone," and finish the Miltonic phrase, or leave the verb to the happy conjectures of my audience? Before him came a soul-subduing whiff of ipecacuanha, and after him lingered a shuddering consciousness of rhubarb. He had lived so much among his medicaments that he had at last become himself a drug, and to have him pass through a sick-chamber was a stronger dose than a conscientious disciple of Hahnemann would think it safe to administer.

Need I remind you of the importance of punctuality in your engagements, and of the worry and distress to patients and their friends which the want of it occasions? One of my old teachers always carried two watches, to make quite sure of being exact, and not only kept his appointments with the regularity of a chronometer, but took great pains to be at his patient's house at the time when he had reason to believe he was expected, even if no express appointment was made. It is a good rule; if you call too early, my lady's hair may not be so smooth as could be wished, and, if you keep her waiting too long, her hair may be smooth, but her temper otherwise.

You will remember, of course, always to get the weather-gage of your patient. I mean, to place him so that the light falls on his face and not on yours. It is a kind of, ocular duel that is about to take place between you; you are going to look through his features into his pulmonary and hepatic and other internal machinery, and he is going to look into yours quite as sharply to see what you think about his probabilities for time or eternity.

No matter how hard he stares at your countenance, he should never be able to read his fate in it. It should be cheerful as long as there is hope, and serene in its gravity when nothing is left but resignation. The face of a physician, like that of a diplomatist, should be impenetrable. Nature is a benevolent old hypocrite; she cheats the sick and the dying with illusions better than any anodynes. If there are cogent reasons why a patient should be undeceived, do it deliberately and advisedly, but do not betray your apprehensions through your tell-tale features.

We had a physician in our city whose smile was commonly reckoned as being worth five thousand dollars a year to him, in the days, too, of moderate incomes. You cannot put on such a smile as that any more than you can get sunshine without sun; there was a tranquil and kindly nature under it that irradiated the pleasant face it made one happier to meet on his daily rounds. But you can cultivate the disposition, and it will work its way through to the surface, nay, more,—you can try to wear a quiet and encouraging look, and it will react on your disposition and make you like what you seem to be, or at least bring you nearer to its own likeness.

Your patient has no more right to all the truth you know than he has to all the medicine in your saddlebags, if you carry that kind of cartridge-box for the ammunition that slays disease. He should get only just so much as is good for him. I have seen a physician examining a patient's chest stop all at once, as he brought out a particular sound with a tap on the collarbone, in the attitude of a pointer who has just come on the scent or sight of a woodcock. You remember the Spartan boy, who, with unmoved countenance, hid the fox that was tearing his vitals beneath his mantle. What he could do in his own suffering you must learn to do for others on whose vital organs disease has fastened its devouring teeth. It is a terrible thing to take away hope, even earthly hope, from a fellow-creature. Be very careful what names you let fall before your patient. He knows what it means when you tell him he has tubercles or Bright's disease, and, if he hears the word carcinoma, he will certainly look it out in a medical dictionary, if he does not interpret its dread significance on the instant. Tell him he has asthmatic symptoms, or a tendency to the gouty diathesis, and he will at once think of all the asthmatic and gouty old patriarchs he has ever heard of, and be comforted. You need not be so cautious in speaking of the health of rich and remote relatives, if he is in the line of succession.

Some shrewd old doctors have a few phrases always on hand for patients that will insist on knowing the pathology of their complaints without the slightest capacity of understanding the scientific explanation. I have known the term "spinal irritation" serve well on such occasions, but I think nothing on the whole has covered so much ground, and meant so little, and given such profound satisfaction to all parties, as the magnificent phrase "congestion of the portal system."

Once more, let me recommend you, as far as possible, to keep your doubts to yourself, and give the patient the benefit of your decision. Firmness, gentle firmness, is absolutely necessary in this and certain other relations. Mr. Rarey with Cruiser, Richard with Lady Ann, Pinel with his crazy people, show what steady nerves can do with the most intractable of animals, the most irresistible of despots, and the most unmanageable of invalids.

If you cannot acquire and keep the confidence of your patient, it is time for you to give place to some other practitioner who can. If you are wise and diligent, you can establish relations with the best of them which they will find it very hard to break. But, if they wish to employ another person, who, as they think, knows more than you do, do not take it as a personal wrong. A patient believes another man can save his life, can restore him to health, which, as he thinks, you have not the skill to do. No matter whether the patient is right or wrong, it is a great impertinence to think you have any property in him. Your estimate of your own ability is not the question, it is what the patient thinks of it. All your wisdom is to him like the lady's virtue in Raleigh's song:

"If she seem not chaste to me, What care I how chaste she be?"

What I call a good patient is one who, having found a good physician, sticks to him till he dies. But there are many very good people who are not what I call good patients. I was once requested to call on a lady suffering from nervous and other symptoms. It came out in the preliminary conversational skirmish, half medical, half social, that I was the twenty-sixth member of the faculty into whose arms, professionally speaking, she had successively thrown herself. Not being a believer in such a rapid rotation of scientific crops, I gently deposited the burden, commending it to the care of number twenty-seven, and, him, whoever he might be, to the care of Heaven.

If there happened to be among my audience any person who wished to know on what principles the patient should choose his physician, I should give him these few precepts to think over:

Choose a man who is personally agreeable, for a daily visit from an intelligent, amiable, pleasant, sympathetic person will cost you no more than one from a sloven or a boor, and his presence will do more for you than any prescription the other will order.

Let him be a man of recognized good sense in other matters, and the chance is that he will be sensible as a practitioner.

Let him be a man who stands well with his professional brethren, whom they approve as honest, able, courteous.

Let him be one whose patients are willing to die in his hands, not one whom they go to for trifles, and leave as soon as they are in danger, and who can say, therefore, that he never loses a patient.

Do not leave the ranks of what is called the regular profession, unless you wish to go farther and fare worse, for you may be assured that its members recognize no principle which hinders their accepting any remedial agent proved to be useful, no matter from what quarter it comes. The difficulty is that the stragglers, organized under fantastic names in pretentious associations, or lurking in solitary dens behind doors left ajar, make no real contributions to the art of healing. When they bring forward a remedial agent like chloral, like the bromide of potassium, like ether, used as an anesthetic, they will find no difficulty in procuring its recognition.

Some of you will probably be more or less troubled by the pretensions of that parody of mediaeval theology which finds its dogma of hereditary depravity in the doctrine of psora, its miracle of transubstantiation in the mystery of its triturations and dilutions, its church in the people who have mistaken their century, and its priests in those who have mistaken their calling. You can do little with persons who are disposed to accept these curious medical superstitions. The saturation-point of individual minds with reference to evidence, and especially medical evidence, differs, and must always continue to differ, very widely. There are those whose minds are satisfied with the decillionth dilution of a scientific proof. No wonder they believe in the efficacy of a similar attenuation of bryony or pulsatilla. You have no fulcrum you can rest upon to lift an error out of such minds as these, often highly endowed with knowledge and talent, sometimes with genius, but commonly richer in the imaginative than the observing and reasoning faculties.

Let me return once more to the young graduate. Your relations to your professional brethren may be a source of lifelong happiness and growth in knowledge and character, or they may make you wretched and end by leaving you isolated from those who should be your friends and counsellors. The life of a physician becomes ignoble when he suffers himself to feed on petty jealousies and sours his temper in perpetual quarrels. You will be liable to meet an uncomfortable man here and there in the profession,—one who is so fond of being in hot water that it is a wonder all the albumen in his body is not coagulated. There are common barrators among doctors as there are among lawyers,—stirrers up of strife under one pretext and another, but in reality because they like it. They are their own worst enemies, and do themselves a mischief each time they assail their neighbors. In my student days I remember a good deal of this Donnybrook-Fair style of quarrelling, more especially in Paris, where some of the noted surgeons were always at loggerheads, and in one of our lively Western cities. Soon after I had set up an office, I had a trifling experience which may serve to point a moral in this direction. I had placed a lamp behind the glass in the entry to indicate to the passer-by where relief from all curable infirmities was to be sought and found. Its brilliancy attracted the attention of a devious youth, who dashed his fist through the glass and upset my modest luminary. All he got by his vivacious assault was that he left portions of integument from his knuckles upon the glass, had a lame hand, was very easily identified, and had to pay the glazier's bill. The moral is that, if the brilliancy of another's reputation excites your belligerent instincts, it is not worth your while to strike at it, without calculating which of you is likely to suffer most, if you do.

You may be assured that when an ill-conditioned neighbor is always complaining of a bad taste in his mouth and an evil atmosphere about him, there is something wrong about his own secretions. In such cases there is an alterative regimen of remarkable efficacy: it is a starvation-diet of letting alone. The great majority of the profession are peacefully inclined. Their pursuits are eminently humanizing, and they look with disgust on the personalities which intrude themselves into the placid domain of an art whose province it is to heal and not to wound.

The intercourse of teacher and student in a large school is necessarily limited, but it should be, and, so far as my experience goes, it is, eminently cordial and kindly. You will leave with regret, and hold in tender remembrance, those who have taken you by the hand at your entrance on your chosen path, and led you patiently and faithfully, until the great gates at its end have swung upon their hinges, and the world lies open before you. That venerable oath to which I have before referred bound the student to regard his instructor in the light of a parent, to treat his children like brothers, to succor him in his day of need. I trust the spirit of the oath of Hippocrates is not dead in the hearts of the students of to-day. They will remember with gratitude every earnest effort, every encouraging word, which has helped them in their difficult and laborious career of study. The names they read on their diplomas will recall faces that are like family-portraits in their memory, and the echo of voices they have listened to so long will linger in their memories far into the still evening of their lives.

One voice will be heard no more which has been familiar to many among you. It is not for me, a stranger to these scenes, to speak his eulogy. I have no right to sadden this hour by dwelling on the deep regrets of friendship, or to bid the bitter tears of sorrow flow afresh. Yet I cannot help remembering what a void the death of such a practitioner as your late instructor must leave in the wide circle of those who leaned upon his counsel and assistance in their hour of need, in a community where he was so widely known and esteemed, in a school where he bore so important a part. There is no exemption from the common doom for him who holds the shield to protect others. The student is called from his bench, the professor from his chair, the practitioner in his busiest period hears a knock more peremptory than any patient's midnight summons, and goes on that unreturning visit which admits of no excuse, and suffers no delay. The call of such a man away from us is the bereavement of a great family. Nor can we help regretting the loss for him of a bright and cheerful earthly future; for the old age of a physician is one of the happiest periods of his life. He is loved and cherished for what he has been, and even in the decline of his faculties there are occasions when his experience is still appealed to, and his trembling hands are looked to with renewing hope and trust, as being yet able to stay the arm of the destroyer.

But if there is so much left for age, how beautiful, how inspiring is the hope of youth! I see among those whom I count as listeners one by whose side I have sat as a fellow-teacher, and by whose instructions I have felt myself not too old to profit. As we borrowed him from your city, I must take this opportunity of telling you that his zeal, intelligence, and admirable faculty as an instructor were heartily and universally recognized among us. We return him, as we trust, uninjured, to the fellow-citizens who have the privilege of claiming him as their own.

And now, gentlemen of the graduating class, nothing remains but for me to bid you, in the name of those for whom I am commissioned and privileged to speak, farewell as students, and welcome as practitioners. I pronounce the two benedictions in the same breath, as the late king's demise and the new king's accession are proclaimed by the same voice at the same moment. You would hardly excuse me if I stooped to any meaner dialect than the classical and familiar language of your prescriptions, the same in which your title to the name of physician is, if, like our own institution, you follow the ancient usage, engraved upon your diplomas.

Valete, JUVENES, artis medicae studiosi; valete, discipuli, valete, filii!

Salvete, VIRI, artis medicae magister; Salvete amici; salvete fratres!



MEDICAL LIBRARIES.

[Dedicatory Address at the opening of the Medical Library in Boston, December 3, 1878.]

It is my appointed task, my honorable privilege, this evening, to speak of what has been done by others. No one can bring his tribute of words into the presence of great deeds, or try with them to embellish the memory of any inspiring achievement, without feeling and leaving with others a sense of their insufficiency. So felt Alexander when he compared even his adored Homer with the hero the poet had sung. So felt Webster when he contrasted the phrases of rhetoric with the eloquence of patriotism and of self-devotion. So felt Lincoln when on the field of Gettysburg he spoke those immortal words which Pericles could not have bettered, which Aristotle could not have criticised. So felt he who wrote the epitaph of the builder of the dome which looks down on the crosses and weathercocks that glitter over London.

We are not met upon a battle-field, except so far as every laborious achievement means a victory over opposition, indifference, selfishness, faintheartedness, and that great property of mind as well as matter,—inertia. We are not met in a cathedral, except so far as every building whose walls are lined with the products of useful and ennobling thought is a temple of the Almighty, whose inspiration has given us understanding. But we have gathered within walls which bear testimony to the self-sacrificing, persevering efforts of a few young men, to whom we owe the origin and development of all that excites our admiration in this completed enterprise; and I might consider my task as finished if I contented myself with borrowing the last word of the architect's epitaph and only saying, Look around you!

The reports of the librarian have told or will tell you, in some detail, what has been accomplished since the 21st of December, 1874, when six gentlemen met at the house of Dr. Henry Ingersoll Bowditch to discuss different projects for a medical library. In less than four years from that time, by the liberality of associations and of individuals, this collection of nearly ten thousand volumes, of five thousand pamphlets, and of one hundred and twenty-five journals, regularly received,—all worthily sheltered beneath this lofty roof,—has come into being under our eyes. It has sprung up, as it were; in the night like a mushroom; it stands before us in full daylight as lusty as an oak, and promising to grow and flourish in the perennial freshness of an evergreen.

To whom does our profession owe this already large collection of books, exceeded in numbers only by four or five of the most extensive medical libraries in the country, and lodged in a building so well adapted to its present needs? We will not point out individually all those younger members of the profession who have accomplished what their fathers and elder brethren had attempted and partially achieved. We need not write their names on these walls, after the fashion of those civic dignitaries who immortalize themselves on tablets of marble and gates of iron. But their contemporaries know them well, and their descendants will not forget them,—the men who first met together, the men who have given their time and their money, the faithful workers, worthy associates of the strenuous agitator who gave no sleep to his eyes, no slumber to his eyelids, until he had gained his ends; the untiring, imperturbable, tenacious, irrepressible, all-subduing agitator who neither rested nor let others rest until the success of the project was assured. If, against his injunctions, I name Dr. James Read Chadwick, it is only my revenge for his having kept me awake so often and so long while he was urging on the undertaking in which he has been preeminently active and triumphantly successful.

We must not forget the various medical libraries which preceded this: that of an earlier period, when Boston contained about seventy regular practitioners, the collection afterwards transferred to the Boston Athenaeum; the two collections belonging to the University; the Treadwell Library at the Massachusetts General Hospital; the collections of the two societies, that for Medical Improvement and that for Medical Observation; and more especially the ten thousand volumes relating to medicine belonging to our noble public city library,—too many blossoms on the tree of knowledge, perhaps, for the best fruit to ripen. But the Massachusetts Medical Society now numbers nearly four hundred members in the city of Boston. The time had arrived for a new and larger movement. There was needed a place to which every respectable member of the medical profession could obtain easy access; where, under one roof, all might find the special information they were seeking; where the latest medical intelligence should be spread out daily as the shipping news is posted on the bulletins of the exchange; where men engaged in a common pursuit could meet, surrounded by the mute oracles of science and art; where the whole atmosphere should be as full of professional knowledge as the apothecary's shop is of the odor of his medicaments. This was what the old men longed for,—the prophets and kings of the profession, who

"Desired it long, But died without the sight."

This is what the young men and those who worked under their guidance undertook to give us. And now such a library, such a reading-room, such an exchange, such an intellectual and social meeting place, we be hold a fact, plain before us. The medical profession of our city, and, let us add, of all those neighboring places which it can reach with its iron arms, is united as never before by the commune vinculum, the common bond of a large, enduring, ennobling, unselfish interest. It breathes a new air of awakened intelligence. It marches abreast of the other learned professions, which have long had their extensive and valuable centralized libraries; abreast of them, but not promising to be content with that position. What glorifies a town like a cathedral? What dignifies a province like a university? What illuminates a country like its scholarship, and what is the nest that hatches scholars but a library?

The physician, some may say, is a practical man and has little use for all this book-learning. Every student has heard Sydenham's reply to Sir Richard Blackmore's question as to what books he should read,—meaning medical books. "Read Don Quixote," was his famous answer. But Sydenham himself made medical books and may be presumed to have thought those at least worth reading. Descartes was asked where was his library, and in reply held up the dissected body of an animal. But Descartes made books, great books, and a great many of them. A physician of common sense without erudition is better than a learned one without common sense, but the thorough master of his profession must have learning added to his natural gifts.

It is not necessary to maintain the direct practical utility of all kinds of learning. Our shelves contain many books which only a certain class of medical scholars will be likely to consult. There is a dead medical literature, and there is a live one. The dead is not all ancient, the live is not all modern. There is none, modern or ancient, which, if it has no living value for the student, will not teach him something by its autopsy. But it is with the live literature of his profession that the medical practitioner is first of all concerned.

Now there has come a great change in our time over the form in which living thought presents itself. The first printed books,—the incunabula,—were inclosed in boards of solid oak, with brazen clasps and corners; the boards by and by were replaced by pasteboard covered with calf or sheepskin; then cloth came in and took the place of leather; then the pasteboard was covered with paper instead of cloth; and at this day the quarterly, the monthly, the weekly periodical in its flimsy unsupported dress of paper, and the daily journal, naked as it came from the womb of the press, hold the larger part of the fresh reading we live upon. We must have the latest thought in its latest expression; the page must be newly turned like the morning bannock; the pamphlet must be newly opened like the ante-prandial oyster.

Thus a library, to meet the need of our time, must take, and must spread out in a convenient form, a great array of periodicals. Our active practitioners read these by preference over almost everything else. Our specialists, more particularly, depend on the month's product, on the yearly crop of new facts, new suggestions, new contrivances, as much as the farmer on the annual yield of his acres. One of the first wants, then, of the profession is supplied by our library in its great array of periodicals from many lands, in many languages. Such a number of medical periodicals no private library would have room for, no private person would pay for, or flood his tables with if they were sent him for nothing. These, I think, with the reports of medical societies and the papers contributed to them, will form the most attractive part of our accumulated medical treasures. They will be also one of our chief expenses, for these journals must be bound in volumes and they require a great amount of shelf-room; all this, in addition to the cost of subscription for those which are not furnished us gratuitously.

It is true that the value of old scientific periodicals is, other things being equal, in the inverse ratio of their age, for the obvious reason that what is most valuable in the earlier volumes of a series is drained off into the standard works with which the intelligent practitioner is supposed to be familiar. But no extended record of facts grows too old to be useful, provided only that we have a ready and sure way of getting at the particular fact or facts we are in search of.

And this leads me to speak of what I conceive to be one of the principal tasks to be performed by the present and the coming generation of scholars, not only in the medical, but in every department of knowledge. I mean the formation of indexes, and more especially of indexes to periodical literature.

This idea has long been working in the minds of scholars, and all who have had occasion to follow out any special subject. I have a right to speak of it, for I long ago attempted to supply the want of indexes in some small measure for my own need. I had a very complete set of the "American Journal of the Medical Sciences;" an entire set of the "North American Review," and many volumes of the reprints of the three leading British quarterlies. Of what use were they to me without general indexes? I looked them all through carefully and made classified lists of all the articles I thought I should most care to read. But they soon outgrew my lists. The "North American Review" kept filling up shelf after shelf, rich in articles which I often wanted to consult, but what a labor to find them, until the index of Mr. Gushing, published a few months since, made the contents of these hundred and twenty volumes as easily accessible as the words in a dictionary! I had a, copy of good Dr. Abraham Rees's Cyclopaedia, a treasure-house to my boyhood which has not lost its value for me in later years. But where to look for what I wanted? I wished to know, for instance, what Dr. Burney had to say about singing. Who would have looked for it under the Italian word cantare? I was curious to learn something of the etchings of Rembrandt, and where should I find it but under the head "Low Countries, Engravers of the,"—an elaborate and most valuable article of a hundred double-columned close-printed quarto pages, to which no reference, even, is made under the title Rembrandt.

There was nothing to be done, if I wanted to know where that which I specially cared for was to be found in my Rees's Cyclopaedia, but to look over every page of its forty-one quarto volumes and make out a brief list of matters of interest which I could not find by their titles, and this I did, at no small expense of time and trouble.

Nothing, therefore, could be more pleasing to me than to see the attention which has been given of late years to the great work of indexing. It is a quarter of a century since Mr. Poole published his "Index to Periodical Literature," which it is much to be hoped is soon to appear in a new edition, grown as it must be to formidable dimensions by the additions of so long a period. The "British and Foreign Medical Review," edited by the late Sir John Forties, contributed to by Huxley, Carpenter, Laycock, and others of the most distinguished scientific men of Great Britain, has an index to its twenty-four volumes, and by its aid I find this valuable series as manageable as a lexicon. The last edition of the "Encyclopaedia Britannica" had a complete index in a separate volume, and the publishers of Appletons' "American Cyclopaedia" have recently issued an index to their useful work, which must greatly add to its value. I have already referred to the index to the "North American Review," which to an American, and especially to a New Englander, is the most interesting and most valuable addition of its kind to our literary apparatus since the publication of Mr. Allibone's "Dictionary of Authors." I might almost dare to parody Mr. Webster's words in speaking of Hamilton, to describe what Mr. Gushing did for the solemn rows of back volumes of our honored old Review which had been long fossilizing on our shelves: "He touched the dead corpse of the 'North American,' and it sprang to its feet." A library of the best thought of the best American scholars during the greater portion of the century was brought to light by the work of the indexmaker as truly as were the Assyrian tablets by the labors of Layard.

A great portion of the best writing and reading literary, scientific, professional, miscellaneous—comes to us now, at stated intervals, in paper covers. The writer appears, as it were, in his shirt-sleeves. As soon as he has delivered his message the book-binder puts a coat on his back, and he joins the forlorn brotherhood of "back volumes," than which, so long as they are unindexed, nothing can be more exasperating. Who wants a lock without a key, a ship without a rudder, a binnacle without a compass, a check without a signature, a greenback without a goldback behind it?

I have referred chiefly to the medical journals, but I would include with these the reports of medical associations, and those separate publications which, coming in the form of pamphlets, heap themselves into chaotic piles and bundles which are worse than useless, taking up a great deal of room, and frightening everything away but mice and mousing antiquarians, or possibly at long intervals some terebrating specialist.

Arranged, bound, indexed, all these at once become accessible and valuable. I will take the first instance which happens to suggest itself. How many who know all about osteoblasts and the experiments of Ollier, and all that has grown out of them, know where to go for a paper by the late Dr. A. L. Peirson of Salem, published in the year 1840, under the modest title, Remarks on Fractures? And if any practitioner who has to deal with broken bones does not know that most excellent and practical essay, it is a great pity, for it answers very numerous questions which will be sure to suggest themselves to the surgeon and the patient as no one of the recent treatises, on my own shelves, at least, can do.

But if indexing is the special need of our time in medical literature, as in every department of knowledge, it must be remembered that it is not only an immense labor, but one that never ends. It requires, therefore, the cooperation of a large number of individuals to do the work, and a large amount of money to pay for making its results public through the press. When it is remembered that the catalogue of the library of the British Museum is contained in nearly three thousand large folios of manuscript, and not all its books are yet included, the task of indexing any considerable branch of science or literature looks as if it were well nigh impossible. But many hands make light work. An "Index Society" has been formed in England, already numbering about one hundred and seventy members. It aims at "supplying thorough indexes to valuable works and collections which have hitherto lacked them; at issuing indexes to the literature of special subjects; and at gathering materials for a general reference index." This society has published a little treatise setting forth the history and the art of indexing, which I trust is in the hands of some of our members, if not upon our shelves.

Something has been done in the same direction by individuals in our own country, as we have already seen. The need of it in the department of medicine is beginning to be clearly felt. Our library has already an admirable catalogue with cross references, the work of a number of its younger members cooperating in the task. A very intelligent medical student, Mr. William D. Chapin, whose excellent project is indorsed by well-known New York physicians and professors, proposes to publish a yearly index to original communications in the medical journals of the United States, classified by authors and subjects. But it is from the National Medical Library at Washington that we have the best promise and the largest expectations. That great and growing collection of fifty thousand volumes is under the eye and hand of a librarian who knows books and how to manage them. For libraries are the standing armies of civilization, and an army is but a mob without a general who can organize and marshal it so as to make it effective. The "Specimen Fasciculus of a Catalogue of the National Medical Library," prepared under the direction of Dr. Billings, the librarian, would have excited the admiration of Haller, the master scholar in medical science of the last century, or rather of the profession in all centuries, and if carried out as it is begun will be to the nineteenth all and more than all that the three Bibliothecae—Anatomica, Chirurgica, and Medicinae-Practicae—were to the eighteenth century. I cannot forget the story that Agassiz was so fond of telling of the king of Prussia and Fichte. It was after the humiliation and spoliation of the kingdom by Napoleon that the monarch asked the philosopher what could be done to regain the lost position of the nation. "Found a great university, Sire," was the answer, and so it was that in the year 1810 the world-renowned University of Berlin came into being. I believe that we in this country can do better than found a national university, whose professors shall be nominated in caucuses, go in and out, perhaps, like postmasters, with every change of administration, and deal with science in the face of their constituency as the courtier did with time when his sovereign asked him what o'clock it was: "Whatever hour your majesty pleases." But when we have a noble library like that at Washington, and a librarian of exceptional qualifications like the gentleman who now holds that office, I believe that a liberal appropriation by Congress to carry out a conscientious work for the advancement of sound knowledge and the bettering of human conditions, like this which Dr. Billings has so well begun, would redound greatly to the honor of the nation. It ought to be willing to be at some charge to make its treasures useful to its citizens, and, for its own sake, especially to that class which has charge of health, public and private. This country abounds in what are called "self-made men," and is justly proud of many whom it thus designates. In one sense no man is self-made who breathes the air of a civilized community. In another sense every man who is anything other than a phonograph on legs is self-made. But if we award his just praise to the man who has attained any kind of excellence without having had the same advantages as others whom, nevertheless, he has equalled or surpassed, let us not be betrayed into undervaluing the mechanic's careful training to his business, the thorough and laborious education of the scholar and the professional man.

Our American atmosphere is vocal with the flippant loquacity of half knowledge. We must accept whatever good can be got out of it, and keep it under as we do sorrel and mullein and witchgrass, by enriching the soil, and sowing good seed in plenty; by good teaching and good books, rather than by wasting our time in talking against it. Half knowledge dreads nothing but whole knowledge.

I have spoken of the importance and the predominance of periodical literature, and have attempted to do justice to its value. But the almost exclusive reading of it is not without its dangers. The journals contain much that is crude and unsound; the presumption; it might be maintained, is against their novelties, unless they come from observers of established credit. Yet I have known a practitioner,—perhaps more than one,—who was as much under the dominant influence of the last article he had read in his favorite medical journal as a milliner under the sway of the last fashion-plate. The difference between green and seasoned knowledge is very great, and such practitioners never hold long enough to any of their knowledge to have it get seasoned.

It is needless to say, then, that all the substantial and permanent literature of the profession should be represented upon our shelves. Much of it is there already, and as one private library after another falls into this by the natural law of gravitation, it will gradually acquire all that is most valuable almost without effort. A scholar should not be in a hurry to part with his books. They are probably more valuable to him than they can be to any other individual. What Swedenborg called "correspondence" has established itself between his intelligence and the volumes which wall him within their sacred inclosure. Napoleon said that his mind was as if furnished with drawers,—he drew out each as he wanted its contents, and closed it at will when done with them. The scholar's mind, to use a similar comparison, is furnished with shelves, like his library. Each book knows its place in the brain as well as against the wall or in the alcove. His consciousness is doubled by the books which encircle him, as the trees that surround a lake repeat themselves in its unruffled waters. Men talk of the nerve that runs to the pocket, but one who loves his books, and has lived long with them, has a nervous filament which runs from his sensorium to every one of them. Or, if I may still let my fancy draw its pictures, a scholar's library is to him what a temple is to the worshipper who frequents it. There is the altar sacred to his holiest experiences. There is the font where his new-born thought was baptized and first had a name in his consciousness. There is the monumental tablet of a dead belief, sacred still in the memory of what it was while yet alive. No visitor can read all this on the lettered backs of the books that have gathered around the scholar, but for him, from the Aldus on the lowest shelf to the Elzevir on the highest, every volume has a language which none but he can interpret. Be patient with the book-collector who loves his companions too well to let them go. Books are not buried with their owners, and the veriest book-miser that ever lived was probably doing far more for his successors than his more liberal neighbor who despised his learned or unlearned avarice. Let the fruit fall with the leaves still clinging round it. Who would have stripped Southey's walls of the books that filled them, when, his mind no longer capable of taking in their meaning, he would still pat and fondle them with the vague loving sense of what they had once been to him,—to him, the great scholar, now like a little child among his playthings?

We need in this country not only the scholar, but the virtuoso, who hoards the treasures which he loves, it may be chiefly for their rarity and because others who know more than he does of their value set a high price upon them. As the wine of old vintages is gently decanted out of its cobwebbed bottles with their rotten corks into clean new receptacles, so the wealth of the New World is quietly emptying many of the libraries and galleries of the Old World into its newly formed collections and newly raised edifices. And this process must go on in an accelerating ratio. No Englishman will be offended if I say that before the New Zealander takes his stand on a broken arch of London Bridge to sketch the ruins of St. Paul's in the midst of a vast solitude, the treasures of the British Museum will have found a new shelter in the halls of New York or Boston. No Catholic will think hardly of my saying that before the Coliseum falls, and with it the imperial city, whose doom prophecy has linked with that of the almost eternal amphitheatre, the marbles, the bronzes, the paintings, the manuscripts of the Vatican will have left the shores of the Tiber for those of the Potomac, the Hudson, the Mississippi, or the Sacramento. And what a delight in the pursuit of the rarities which the eager book-hunter follows with the scent of a beagle!

Shall I ever forget that rainy day in Lyons, that dingy bookshop, where I found the Aetius, long missing from my Artis bledicae Principes, and where I bought for a small pecuniary consideration, though it was marked rare, and was really tres rare, the Aphorisms of Hippocrates, edited by and with a preface from the hand of Francis Rabelais? And the vellum-bound Tulpius, which I came upon in Venice, afterwards my only reading when imprisoned in quarantine at Marseilles, so that the two hundred and twenty-eight cases he has recorded are, many of them, to this day still fresh in my memory. And the Schenckius,—the folio filled with casus rariores, which had strayed in among the rubbish of the bookstall on the boulevard,—and the noble old Vesalius with its grand frontispiece not unworthy of Titian, and the fine old Ambroise Pare, long waited for even in Paris and long ago, and the colossal Spigelius with his eviscerated beauties, and Dutch Bidloo with its miracles of fine engraving and bad dissection, and Italian Mascagni, the despair of all would-be imitators, and pre-Adamite John de Ketam, and antediluvian Berengarius Carpensis,—but why multiply names, every one of which brings back the accession of a book which was an event almost like the birth of an infant?

A library like ours must exercise the largest hospitality. A great many books may be found in every large collection which remind us of those apostolic looking old men who figure on the platform at our political and other assemblages. Some of them have spoken words of wisdom in their day, but they have ceased to be oracles; some of them never had any particularly important message for humanity, but they add dignity to the meeting by their presence; they look wise, whether they are so or not, and no one grudges them their places of honor. Venerable figure-heads, what would our platforms be without you?

Just so with our libraries. Without their rows of folios in creamy vellum, or showing their black backs with antique lettering of tarnished gold, our shelves would look as insufficient and unbalanced as a column without its base, as a statue without its pedestal. And do not think they are kept only to be spanked and dusted during that dreadful period when their owner is but too thankful to become an exile and a wanderer from the scene of single combats between dead authors and living housemaids. Men were not all cowards before Agamemnon or all fools before the days of Virchow and Billroth. And apart from any practical use to be derived from the older medical authors, is there not a true pleasure in reading the accounts of great discoverers in their own words? I do not pretend to hoist up the Bibliotheca Anatomica of Mangetus and spread it on my table every day. I do not get out my great Albinus before every lecture on the muscles, nor disturb the majestic repose of Vesalius every time I speak of the bones he has so admirably described and figured. But it does please me to read the first descriptions of parts to which the names of their discoverers or those who have first described them have become so joined that not even modern science can part them; to listen to the talk of my old volume as Willis describes his circle and Fallopius his aqueduct and Varolius his bridge and Eustachius his tube and Monro his foramen,—all so well known to us in the human body; it does please me to know the very words in which Winslow described the opening which bears his name, and Glisson his capsule and De Graaf his vesicle; I am not content until I know in what language Harvey announced his discovery of the circulation, and how Spigelius made the liver his perpetual memorial, and Malpighi found a monument more enduring than brass in the corpuscles of the spleen and the kidney.

But after all, the readers who care most for the early records of medical science and art are the specialists who are dividing up the practice of medicine and surgery as they were parcelled out, according to Herodotus, by the Egyptians. For them nothing is too old, nothing is too new, for to their books of all others is applicable the saying of D'Alembert that the author kills himself in lengthening out what the reader kills himself in trying to shorten.

There are practical books among these ancient volumes which can never grow old. Would you know how to recognize "male hysteria" and to treat it, take down your Sydenham; would you read the experience of a physician who was himself the subject of asthma, and who, notwithstanding that, in the words of Dr. Johnson, "panted on till ninety," you will find it in the venerable treatise of Sir John Floyer; would you listen to the story of the King's Evil cured by the royal touch, as told by a famous chirurgeon who fully believed in it, go to Wiseman; would you get at first hand the description of the spinal disease which long bore his name, do not be startled if I tell you to go to Pott,—to Percival Pott, the great surgeon of the last century.

There comes a time for every book in a library when it is wanted by somebody. It is but a few weeks since one of the most celebrated physicians in the country wrote to me from a great centre of medical education to know if I had the works of Sanctorius, which he had tried in vain to find. I could have lent him the "Medicina Statica," with its frontispiece showing Sanctorius with his dinner on the table before him, in his balanced chair which sunk with him below the level of his banquet-board when he had swallowed a certain number of ounces,—an early foreshadowing of Pettenkofer's chamber and quantitative physiology,—but the "Opera Omnia" of Sanctorius I had never met with, and I fear he had to do without it.

I would extend the hospitality of these shelves to a class of works which we are in the habit of considering as being outside of the pale of medical science, properly so called, and sometimes of coupling with a disrespectful name. Such has always been my own practice. I have welcomed Culpeper and Salmon to my bookcase as willingly as Dioscorides or Quincy, or Paris or Wood and Bache. I have found a place for St. John Long, and read the story of his trial for manslaughter with as much interest as the laurel-water case in which John Hunter figured as a witness. I would give Samuel Hahnemann a place by the side of Samuel Thomson. Am I not afraid that some student of imaginative turn and not provided with the needful cerebral strainers without which all the refuse of gimcrack intelligences gets into the mental drains and chokes them up,—am I not afraid that some such student will get hold of the "Organon" or the "Maladies Chroniques" and be won over by their delusions, and so be lost to those that love him as a man of common sense and a brother in their high calling? Not in the least. If he showed any symptoms of infection I would for once have recourse to the principle of similia similibus. To cure him of Hahnemann I would prescribe my favorite homoeopathic antidote, Okie's Bonninghausen. If that failed, I would order Grauvogl as a heroic remedy, and if he survived that uncured, I would give him my blessing, if I thought him honest, and bid him depart in peace. For me he is no longer an individual. He belongs to a class of minds which we are bound to be patient with if their Maker sees fit to indulge them with existence. We must accept the conjuring ultra-ritualist, the dreamy second adventist, the erratic spiritualist, the fantastic homoeopathist, as not unworthy of philosophic study; not more unworthy of it than the squarers of the circle and the inventors of perpetual motion, and the other whimsical visionaries to whom De Morgan has devoted his most instructive and entertaining "Budget of Paradoxes." I hope, therefore, that our library will admit the works of the so-called Eclectics, of the Thomsonians, if any are in existence, of the Clairvoyants, if they have a literature, and especially of the Homoeopathists. This country seems to be the place for such a collection, which will by and by be curious and of more value than at present, for Homoeopathy seems to be following the pathological law of erysipelas, fading out where it originated as it spreads to new regions. At least I judge so by the following translated extract from a criticism of an American work in the "Homoeopatische Rundschau" of Leipzig for October, 1878, which I find in the "Homoeopathic Bulletin" for the month of November just passed: "While we feel proud of the spread and rise of Homoeopathy across the ocean, and while the Homoeopathic works reaching us from there, and published in a style such as is unknown in Germany, bear eloquent testimony to the eminent activity of our transatlantic colleagues, we are overcome by sorrowful regrets at the position Homoeopathy occupies in Germany. Such a work [as the American one referred to] with us would be impossible; it would lack the necessary support."

By all means let our library secure a good representation of the literature of Homoeopathy before it leaves us its "sorrowful regrets" and migrates with its sugar of milk pellets, which have taken the place of the old pilulae micae panis, to Alaska, to "Nova Zembla, or the Lord knows where."

What shall I say in this presence of the duties of a Librarian? Where have they ever been better performed than in our own public city library, where the late Mr. Jewett and the living Mr. Winsor have shown us what a librarian ought to be,—the organizing head, the vigilant guardian, the seeker's index, the scholar's counsellor? His work is not merely that of administration, manifold and laborious as its duties are. He must have a quick intelligence and a retentive memory. He is a public carrier of knowledge in its germs. His office is like that which naturalists attribute to the bumble-bee,—he lays up little honey for himself, but he conveys the fertilizing pollen from flower to flower.

Our undertaking, just completed,—and just begun—has come at the right time, not a day too soon. Our practitioners need a library like this, for with all their skill and devotion there is too little genuine erudition, such as a liberal profession ought to be able to claim for many of its members. In reading the recent obituary notices of the late Dr. Geddings of South Carolina, I recalled what our lamented friend Dr. Coale used to tell me of his learning and accomplishments, and I could not help reflecting how few such medical scholars we had to show in Boston or New England. We must clear up this unilluminated atmosphere, and here,—here is the true electric light which will irradiate its darkness.

The public will catch the rays reflected from the same source of light, and it needs instruction on the great subjects of health and disease,—needs it sadly. It is preyed upon by every kind of imposition almost without hindrance. Its ignorance and prejudices react upon the profession to the great injury of both. The jealous feeling, for instance, with regard to such provisions for the study of anatomy as are sanctioned by the laws in this State and carried out with strict regard to those laws, threatens the welfare, if not the existence of institutions for medical instruction wherever it is not held in check by enlightened intelligence. And on the other hand the profession has just been startled by a verdict against a physician, ruinous in its amount,—enough to drive many a hard-working young practitioner out of house and home,—a verdict which leads to the fear that suits for malpractice may take the place of the panel game and child-stealing as a means of extorting money. If the profession in this State, which claims a high standard of civilization, is to be crushed and ground beneath the upper millstone of the dearth of educational advantages and the lower millstone of ruinous penalties for what the ignorant ignorantly shall decide to be ignorance, all I can say is

God save the Commonhealth of Massachusetts!

Once more, we cannot fail to see that just as astrology has given place to astronomy, so theology, the science of Him whom by searching no man can find out, is fast being replaced by what we may not improperly call theonomy, or the science of the laws according to which the Creator acts. And since these laws find their fullest manifestations for us, at least, in rational human natures, the study of anthropology is largely replacing that of scholastic divinity. We must contemplate our Maker indirectly in human attributes as we talk of Him in human parts of speech. And this gives a sacredness to the study of man in his physical, mental, moral, social, and religious nature which elevates the faithful students of anthropology to the dignity of a priesthood, and sheds a holy light on the recorded results of their labors, brought together as they are in such a collection as this which is now spread out before us.

Thus, then, our library is a temple as truly as the dome-crowned cathedral hallowed by the breath of prayer and praise, where the dead repose and the living worship. May it, with all its treasures, be consecrated like that to the glory of God, through the contributions it shall make to the advancement of sound knowledge, to the relief of human suffering, to the promotion of harmonious relations between the members of the two noble professions which deal with the diseases of the soul and with those of the body, and to the common cause in which all good men are working, the furtherance of the well-being of their fellow-creatures!

NOTE.—As an illustration of the statement in the last paragraph but one, I take the following notice from the "Boston Daily Advertiser," of December 4th, the day after the delivery of the address: "Prince Lucien Bonaparte is now living in London, and is devoting himself to the work of collecting the creeds of all religions and sects, with a view to their classification,—his object being simply scientific or anthropological."

Since delivering the address, also, I find a leading article in the "Cincinnati Lancet and Clinic" of November 30th, headed "The Decadence of Homoeopathy," abundantly illustrated by extracts from the "Homoeopathic Times," the leading American organ of that sect.

In the New York "Medical Record" of the same date, which I had not seen before the delivery of my address, is an account of the action of the Homoeopathic Medical Society of Northern New York, in which Hahnemann's theory of "dynamization" is characterized in a formal resolve as "unworthy the confidence of the Homoeopathic profession."

It will be a disappointment to the German Homoeopathists to read in the "Homoeopathic Times" such a statement as the following: "Whatever the influences have been which have checked the outward development of Homoeopathy, it is plainly evident that the Homoeopathic school, as regards the number of its openly avowed representatives, has attained its majority, and has begun to decline both in this country and in England."

All which is an additional reason for making a collection of the incredibly curious literature of Homoeopathy before that pseudological inanity has faded out like so many other delusions.



SOME OF MY EARLY TEACHERS

[A Farewell Address to the Medical School of Harvard University, November 28, 1882.]

I had intended that the recitation of Friday last should be followed by a few parting words to my class and any friends who might happen to be in the lecture-room. But I learned on the preceding evening that there was an expectation, a desire, that my farewell should take a somewhat different form; and not to disappoint the wishes of those whom I was anxious to gratify, I made up my mind to appear before you with such hasty preparation as the scanty time admitted.

There are three occasions upon which a human being has a right to consider himself as a centre of interest to those about him: when he is christened, when he is married, and when he is buried. Every one is the chief personage, the hero, of his own baptism, his own wedding, and his own funeral.

There are other occasions, less momentous, in which one may make more of himself than under ordinary circumstances he would think it proper to do; when he may talk about himself, and tell his own experiences, in fact, indulge in a more or less egotistic monologue without fear or reproach.

I think I may claim that this is one of those occasions. I have delivered my last anatomical lecture and heard my class recite for the last time. They wish to hear from me again in a less scholastic mood than that in which they have known me. Will you not indulge me in telling you something of my own story?

This is the thirty-sixth Course of Lectures in which I have taken my place and performed my duties as Professor of Anatomy. For more than half of my term of office I gave instruction in Physiology, after the fashion of my predecessors and in the manner then generally prevalent in our schools, where the physiological laboratory was not a necessary part of the apparatus of instruction. It was with my hearty approval that the teaching of Physiology was constituted a separate department and made an independent Professorship. Before my time, Dr. Warren had taught Anatomy, Physiology, and Surgery in the same course of Lectures, lasting only three or four months. As the boundaries of science are enlarged, new divisions and subdivisions of its territories become necessary. In the place of six Professors in 1847, when I first became a member of the Faculty, I count twelve upon the Catalogue before me, and I find the whole number engaged in the work of instruction in the Medical School amounts to no less than fifty.

Since I began teaching in this school, the aspect of many branches of science has undergone a very remarkable transformation. Chemistry and Physiology are no longer what they were, as taught by the instructors of that time. We are looking forward to the synthesis of new organic compounds; our artificial madder is already in the market, and the indigo-raisers are now fearing that their crop will be supplanted by the manufactured article. In the living body we talk of fuel supplied and work done, in movement, in heat, just as if we were dealing with a machine of our own contrivance.

A physiological laboratory of to-day is equipped with instruments of research of such ingenious contrivance, such elaborate construction, that one might suppose himself in a workshop where some exquisite fabric was to be wrought, such as Queens love to wear, and Kings do not always love to pay for. They are, indeed, weaving a charmed web, for these are the looms from which comes the knowledge that clothes the nakedness of the intellect. Here are the mills that grind food for its hunger, and "is not the life more than meat, and the body than raiment?"

But while many of the sciences have so changed that the teachers of the past would hardly know them, it has not been so with the branch I teach, or, rather, with that division of it which is chiefly taught in this amphitheatre. General anatomy, or histology, on the other hand, is almost all new; it has grown up, mainly, since I began my medical studies. I never saw a compound microscope during my years of study in Paris. Individuals had begun to use the instrument, but I never heard it alluded to by either Professors or students. In descriptive anatomy I have found little to unlearn, and not a great deal that was both new and important to learn. Trifling additions are made from year to year, not to be despised and not to be overvalued. Some of the older anatomical works are still admirable, some of the newer ones very much the contrary. I have had recent anatomical plates brought me for inspection, and I have actually button-holed the book-agent, a being commonly as hard to get rid of as the tar-baby in the negro legend, that I might put him to shame with the imperial illustrations of the bones and muscles in the great folio of Albinus, published in 1747, and the unapproached figures of the lymphatic system of Mascagni, now within a very few years of a century old, and still copied, or, rather, pretended to be copied, in the most recent works on anatomy.

I am afraid that it is a good plan to get rid of old Professors, and I am thankful to hear that there is a movement for making provision for those who are left in need when they lose their offices and their salaries. I remember one of our ancient Cambridge Doctors once asked me to get into his rickety chaise, and said to me, half humorously, half sadly, that he was like an old horse,—they had taken off his saddle and turned him out to pasture. I fear the grass was pretty short where that old servant of the public found himself grazing. If I myself needed an apology for holding my office so long, I should find it in the fact that human anatomy is much the same study that it was in the days of Vesalius and Fallopius, and that the greater part of my teaching was of such a nature that it could never become antiquated.

Let me begin with my first experience as a medical student. I had come from the lessons of Judge Story and Mr. Ashmun in the Law School at Cambridge. I had been busy, more or less, with the pages of Blackstone and Chitty, and other text-books of the first year of legal study. More or less, I say, but I am afraid it was less rather than more. For during that year I first tasted the intoxicating pleasure of authorship. A college periodical, conducted by friends of mine, still undergraduates, tempted me into print, and there is no form of lead-poisoning which more rapidly and thoroughly pervades the blood and bones and marrow than that which reaches the young author through mental contact with type-metal. Qui a bu, boira,—he who has once been a drinker will drink again, says the French proverb. So the man or woman who has tasted type is sure to return to his old indulgence sooner or later. In that fatal year I had my first attack of authors' lead-poisoning, and I have never got quite rid of it from that day to this. But for that I might have applied myself more diligently to my legal studies, and carried a green bag in place of a stethoscope and a thermometer up to the present day.
