Accident is the great chemist and toxicologist. Battle is the great vivisector. Hunger has inst.i.tuted researches on food such as no Liebig, no Academic Commission has ever recorded.
Medicine, sometimes impertinently, often ignorantly, often carelessly called "allopathy," appropriates everything from every source that can be of the slightest use to anybody who is ailing in any way, or like to be ailing from any cause. It learned from a monk how to use antimony, from a Jesuit how to cure agues, from a friar how to cut for stone, from a soldier how to treat gout, from a sailor how to keep off scurvy, from a postmaster how to sound the Eustachian tube, from a dairy-maid how to prevent small-pox, and from an old market-woman how to catch the itch-insect. It borrowed acupuncture and the moxa from the j.a.panese heathen, and was taught the use of lobelia by the American savage.
It stands ready to-day to accept anything from any theorist, from any empiric who can make out a good case for his discovery or his remedy.
"Science" is one of its benefactors, but only one, out of many. Ask the wisest practising physician you know, what branches of science help him habitually, and what amount of knowledge relating to each branch he requires for his professional duties. He will tell you that scientific training has a value independent of all the special knowledge acquired.
He will tell you that many facts are explained by studying them in the wider range of related facts to which they belong. He will gratefully recognize that the anatomist has furnished him with indispensable data, that the physiologist has sometimes put him on the track of new modes of treatment, that the chemist has isolated the active principles of his medicines, has taught him how to combine them, has from time to time offered him new remedial agencies, and so of others of his allies. But he will also tell you, if I am not mistaken, that his own branch of knowledge is so extensive and so perplexing that he must accept most of his facts ready made at their hands. He will own to you that in the struggle for life which goes on day and night in our thoughts as in the outside world of nature, much that he learned under the name of science has died out, and that simple homely experience has largely taken the place of that scholastic knowledge to which he and perhaps some of his instructors once attached a paramount importance.
This, then, is my view of scientific training as conducted in courses such as you are entering on. Up to a certain point I believe in set Lectures as excellent adjuncts to what is far more important, practical instruction at the bedside, in the operating room, and under the eye of the Demonstrator. But I am so far from wishing these courses extended, that I think some of them--suppose I say my own--would almost bear curtailing. Do you want me to describe more branches of the sciatic and crural nerves? I can take Fischer"s plates, and lecturing on that scale fill up my whole course and not finish the nerves alone. We must stop somewhere, and for my own part I think the scholastic exercises of our colleges have already claimed their full share of the student"s time without our seeking to extend them.
I trust I have vindicated the apparent inconsequence of teaching young students a good deal that seems at first sight profitless, but which helps them to learn and retain what is profitable. But this is an inquisitive age, and if we insist on piling up beyond a certain height knowledge which is in itself mere trash and lumber to a man whose life is to be one long fight with death and disease, there will be some sharp questions asked by and by, and our quick-witted people will perhaps find they can get along as well without the professor"s cap as without the bishop"s mitre and the monarch"s crown.
I myself have nothing to do with clinical teaching. Yet I do not hesitate to say it is more essential than all the rest put together, so far as the ordinary practice of medicine is concerned; and this is by far the most important thing to be learned, because it deals with so many more lives than any other branch of the profession. So of personal instruction, such as we give and others give in the interval of lectures, much of it at the bedside, some of it in the laboratory, some in the microscope-room, some in the recitation-room, I think it has many advantages of its own over the winter course, and I do not wish to see it shortened for the sake of prolonging what seems to me long enough already.
If I am jealous of the tendency to expand the time given to the acquisition of curious knowledge, at the expense of the plain old-fashioned bedside teachings, I only share the feeling which Sydenham expressed two hundred years ago, using an image I have already borrowed.
"He would be no honest and successful pilot who was to apply himself with less industry to avoid rocks and sands and bring his vessel safely home, than to search into the causes of the ebbing and flowing of the sea, which, though very well for a philosopher, is foreign to him whose business it is to secure the ship. So neither will a physician, whose province it is to cure diseases, be able to do so, though he be a person of great genius, who bestows less time on the hidden and intricate method of nature, and adapting his means thereto, than on curious and subtle speculation."
"Medicine is my wife and Science is my mistress," said Dr. Rush. I do not think that the breach of the seventh commandment can be shown to have been of advantage to the legitimate owner of his affections. Read what Dr. Elisha Bartlett says of him as a pract.i.tioner, or ask one of our own honored ex-professors, who studied under him, whether Dr. Rush had ever learned the meaning of that saying of Lord Bacon, that man is the minister and interpreter of Nature, or whether he did not speak habitually of Nature as an intruder in the sick room, from which his art was to expel her as an incompetent and a meddler.
All a man"s powers are not too much for such a profession as Medicine.
"He is a learned man," said old Parson Emmons of Franklin, "who understands one subject, and he is a very learned man who understands two subjects." Schonbein says he has been studying oxygen for thirty years. Mitscherlich said it took fourteen years to establish a new fact in chemistry. Aubrey says of Harvey, the discoverer of the circulation, that "though all his profession would allow him to be an excellent anatomist, I have never heard of any who admired his therapeutic way." My learned and excellent friend before referred to, Dr. Brown of Edinburgh, from whose very lively and sensible Essay, "Locke and Sydenham," I have borrowed several of my citations, contrasts Sir Charles Bell, the discoverer, the man of science, with Dr. Abercrombie, the master in the diagnosis and treatment of disease. It is through one of the rarest of combinations that we have in our Faculty a teacher on whom the scientific mantle of Bell has fallen, and who yet stands preeminent in the practical treatment of the cla.s.s of diseases which his inventive and ardent experimental genius has ill.u.s.trated. M.
Brown-Sequard"s example is as, eloquent as his teaching in proof of the advantages of well directed scientific investigation. But those who emulate his success at once as a discoverer and a pract.i.tioner must be content like him to limit their field of practice. The highest genius cannot afford in our time to forget the ancient precept, Divide et impera.
"I suppose I must go and earn this guinea," said a medical man who was sent for while he was dissecting an animal. I should not have cared to be his patient. His dissection would do me no good, and his thoughts would be too much upon it. I want a whole man for my doctor, not a half one. I would have sent for a humbler pract.i.tioner, who would have given himself entirely to me, and told the other--who was no less a man than John Hunter--to go on and finish the dissection of his tiger.
Sydenham"s "Read Don Quixote" should be addressed not to the student, but to the Professor of today. Aimed at him it means, "Do not be too learned."
Do not think you are going to lecture to picked young men who are training themselves to be scientific discoverers. They are of fair average capacity, and they are going to be working doctors.
These young men are to have some very serious vital facts to deal with.
I will mention a few of them.
Every other resident adult you meet in these streets is or will be more or less tuberculous. This is not an extravagant estimate, as very nearly one third of the deaths of adults in Boston last year were from phthisis. If the relative number is less in our other northern cities, it is probably in a great measure because they are more unhealthy; that is, they have as much, or nearly as much, consumption, but they have more fevers or other fatal diseases.
These heavy-eyed men with the alcoholized brains, these pallid youths with the nicotized optic ganglia and thinking-marrows brown as their own meerschaums, of whom you meet too many,--will ask all your wisdom to deal with their poisoned nerves and their enfeebled wills.
Nearly seventeen hundred children under five years of age died last year in this city. A poor human article, no doubt, in many cases, still, worth an attempt to save them, especially when we remember the effect of Dr. Clarke"s suggestion at the Dublin Hospital, by which some twenty-five or thirty thousand children"s lives have probably been saved in a single city.
Again, the complaint is often heard that the native population is not increasing so rapidly as in former generations. The breeding and nursing period of American women is one of peculiar delicacy and frequent infirmity. Many of them must require a considerable interval between the reproductive efforts, to repair damages and regain strength. This matter is not to be decided by an appeal to unschooled nature. It is the same question as that of the deformed pelvis,--one of degree. The facts of mal-vitalization are as much to be attended to as those of mal-formation. If the woman with a twisted pelvis is to be considered an exempt, the woman with a defective organization should be recognized as belonging to the invalid corps. We shudder to hear what is alleged as to the prevalence of criminal practices; if back of these there can be shown organic incapacity or overtaxing of too limited powers, the facts belong to the province of the practical physician, as well as of the moralist and the legislator, and require his gravest consideration.
Take the important question of bleeding. Is venesection done with forever? Six years ago it was said here in an introductory Lecture that it would doubtless come back again sooner or later. A fortnight ago I found myself in the cars with one of the most sensible and esteemed pract.i.tioners in New England. He took out his wallet and showed me two lancets, which he carried with him; he had never given up their use.
This is a point you will have to consider.
Or, to mention one out of many questionable remedies, shall you give Veratrum Viride in fevers and inflammations? It makes the pulse slower in these affections. Then the presumption would naturally be that it does harm. The caution with reference to it on this ground was long ago recorded in the Lecture above referred to. See what Dr. John Hughes Bennett says of it in the recent edition of his work on Medicine.
Nothing but the most careful clinical experience can settle this and such points of treatment.
These are all practical questions--questions of life and death, and every day will be full of just such questions. Take the problem of climate. A patient comes to you with asthma and wants to know where he can breathe; another comes to you with phthisis and wants to know where he can live. What boy"s play is nine tenths of all that is taught in many a pretentious course of lectures, compared with what an accurate and extensive knowledge of the advantages and disadvantages of different residences in these and other complaints would be to a practising physician.
I saw the other day a gentleman living in Canada, who had spent seven successive winters in Egypt, with the entire relief of certain obscure thoracic symptoms which troubled him while at home. I saw, two months ago, another gentleman from Minnesota, an observer and a man of sense, who considered that State as the great sanatorium for all pulmonary complaints. If half our grown population are or will be more or less tuberculous, the question of colonizing Florida a.s.sumes a new aspect.
Even within the borders of our own State, the very interesting researches of Dr. Bowditch show that there is a great variation in the amount of tuberculous disease in different towns, apparently connected with local conditions. The hygienic map of a State is quite as valuable as its geological map, and it is the business of every practising physician to know it thoroughly. They understand this in England, and send a patient with a dry irritating cough to Torquay or Penzance, while they send another with relaxed bronchial membranes to Clifton or Brighton. Here is another great field for practical study.
So as to the all-important question of diet. "Of all the means of cure at our command," says Dr. Bennett, "a regulation of the quant.i.ty and quality of the diet is by far the most powerful." Dr. MacCormac would perhaps except the air we breathe, for he thinks that impure air, especially in sleeping rooms, is the great cause of tubercle. It is sufficiently proved that the American,--the New Englander,--the Bostonian, can breed strong and sound children, generation after generation,--nay, I have shown by the record of a particular family that vital losses may be retrieved, and a feeble race grow to l.u.s.ty vigor in this very climate and locality. Is not the question why our young men and women so often break down, and how they can be kept from breaking down, far more important for physicians to settle than whether there is one cranial vertebra, or whether there are four, or none?
--But I have a taste for the h.o.m.ologies, I want to go deeply into the subject of embryology, I want to a.n.a.lyze the protonihilates precipitated from pigeon"s milk by the action of the lunar spectrum,--shall I not follow my star,--shall I not obey my instinct,--shall I not give myself to the lofty pursuits of science for its own sake?
Certainly you may, if you like. But take down your sign, or never put it up. That is the way Dr. Owen and Dr. Huxley, Dr. Aga.s.siz and Dr. Jeffries Wyman, Dr. Gray and Dr. Charles T. Jackson settled the difficulty. We all admire the achievements of this band of distinguished doctors who do not practise. But we say of their work and of all pure science, as the French officer said of the charge of the six hundred at Balaclava, "C"est magnifique, mais ce n"est pas la guerre,"--it is very splendid, but it is not a practising doctor"s business. His patient has a right to the cream of his life and not merely to the thin milk that is left after "science" has skimmed it off. The best a physician can give is never too good for the patient.
It is often a disadvantage to a young pract.i.tioner to be known for any accomplishment outside of his profession. Haller lost his election as Physician to the Hospital in his native city of Berne, princ.i.p.ally on the ground that he was a poet. In his later years the physician may venture more boldly. Astruc was sixty-nine years old when he published his "Conjectures," the first attempt, we are told, to decide the authorship of the Pentateuch showing anything like a discerning criticism. Sir Benjamin Brodie was seventy years old before he left his physiological and surgical studies to indulge in psychological speculations. The period of pupilage will be busy enough in acquiring the knowledge needed, and the season of active practice will leave little leisure for any but professional studies.
Dr. Graves of Dublin, one of the first clinical teachers of our time, always insisted on his students" beginning at once to visit the hospital. At the bedside the student must learn to treat disease, and just as certainly as we spin out and multiply our academic prelections we shall work in more and more stuffing, more and more rubbish, more and more irrelevant, useless detail which the student will get rid of just as soon as he leaves us. Then the next thing will be a new organization, with an examining board of first-rate practical men, who will ask the candidate questions that mean business,--who will make him operate if he is to be a surgeon, and try him at the bedside if he is to be a physician,--and not puzzle him with scientific conundrums which not more than one of the questioners could answer himself or ever heard of since he graduated.
Or these women who are hammering at the gates on which is written "No admittance for the mothers of mankind," will by and by organize an inst.i.tution, which starting from that skilful kind of nursing which Florence Nightingale taught so well, will work backwards through anodynes, palliatives, curatives, preventives, until with little show of science it imparts most of what is most valuable in those branches of the healing art it professes to teach. When that time comes, the fitness of women for certain medical duties, which Hecquet advocated in 1708, which Douglas maintained in 1736, which Dr. John Ware, long the honored Professor of Theory and Practice in this Inst.i.tution, upheld within our own recollection in the face of his own recorded opinion to the contrary, will very possibly be recognized.
My advice to every teacher less experienced than myself would be, therefore: Do not fret over the details you have to omit; you probably teach altogether too many as it is. Individuals may learn a thing with once hearing it, but the only way of teaching a whole cla.s.s is by enormous repet.i.tion, representation, and ill.u.s.tration in all possible forms. Now and then you will have a young man on your benches like the late Waldo Burnett,--not very often, if you lecture half a century. You cannot pretend to lecture chiefly for men like that,--a Mississippi raft might as well take an ocean-steamer in tow. To meet his wants you would have to leave the rest of your cla.s.s behind and that you must not do.
President Allen of Jefferson College says that his instruction has been successful in proportion as it has been elementary. It may be a humiliating statement, but it is one which I have found true in my own experience.
To the student I would say, that however plain and simple may be our teaching, he must expect to forget much which he follows intelligently in the lecture-room. But it is not the same as if he had never learned it. A man must get a thing before he can forget it. There is a great world of ideas we cannot voluntarily recall,--they are outside the limits of the will. But they sway our conscious thought as the unseen planets influence the movements of those within the sphere of vision. No man knows how much he knows,--how many ideas he has,--any more than he knows how many blood-globules roll in his veins. Sometimes accident brings back here and there one, but the mind is full of irrevocable remembrances and unthinkable thoughts, which take a part in all its judgments as indestructible forces. Some of you must feel your scientific deficiencies painfully after your best efforts. But every one can acquire what is most essential. A man of very moderate ability may be a good physician, if he devotes himself faithfully to the work. More than this, a positively dull man, in the ordinary acceptation of the term, sometimes makes a safer pract.i.tioner than one who has, we will say, five per cent. more brains than his average neighbor, but who thinks it is fifty per cent. more. Skulls belonging to this last variety of the human race are more common, I may remark, than specimens like the Neanderthal cranium, a cast of which you will find on the table in the Museum.
Whether the average talent be high or low, the Colleges of the land must make the best commodity they can out of such material as the country and the cities furnish them. The community must have Doctors as it must have bread. It uses up its Doctors just as it wears out its shoes, and requires new ones. All the bread need not be French rolls, all the shoes need not be patent leather ones; but the bread must be something that can be eaten, and the shoes must be something that can be worn. Life must somehow find food for the two forces that rub everything to pieces, or burn it to ashes,--friction and oxygen. Doctors are oxydable products, and the schools must keep furnishing new ones as the old ones turn into oxyds; some of first-rate quality that burn with a great light, some of a lower grade of brilliancy, some honestly, unmistakably, by the grace of G.o.d, of moderate gifts, or in simpler phrase, dull.
The public will give every honest and reasonably competent worker in the healing art a hearty welcome. It is on the whole very loyal to the Medical Profession. Three successive years have borne witness to the feeling with which this Inst.i.tution, representing it in its educational aspect, is regarded by those who are themselves most honored and esteemed. The great Master of Natural Science bade the last year"s cla.s.s farewell in our behalf, in those accents which delight every audience.
The Head of our ancient University honored us in the same way in the preceding season. And how can we forget that other occasion when the Chief Magistrate of the Commonwealth, that n.o.ble citizen whom we have just lost, large-souled, sweet-natured, always ready for every kind office, came among us at our bidding, and talked to us of our duties in words as full of wisdom as his heart was of goodness?
You have not much to fear, I think, from the fancy pract.i.tioners. The vulgar quackeries drop off, atrophied, one after another. h.o.m.oeopathy has long been encysted, and is carried on the body medical as quietly as an old wen. Every year gives you a more reasoning and reasonable people to deal with. See how it is in Literature. The dynasty of British dogmatists, after lasting a hundred years and more, is on its last legs.
Thomas Carlyle, third in the line of descent, finds an audience very different from those which listened to the silver speech of Samuel Taylor Coleridge and the sonorous phrases of Samuel Johnson. We read him, we smile at his clotted English, his "swarmery" and other picturesque expressions, but we lay down his tirade as we do one of Dr.
c.u.mming"s interpretations of prophecy, which tells us that the world is coming to an end next week or next month, if the weather permits,--not otherwise,--feeling very sure that the weather will be unfavorable.
It is the same common-sense public you will appeal to. The less pretension you make, the better they will like you in the long run. I hope we shall make everything as plain and as simple to you as we can.
I would never use a long word, even, where a short one would answer the purpose. I know there are professors in this country who "ligate"
arteries. Other surgeons only tie them, and it stops the bleeding just as well. It is the familiarity and simplicity of bedside instruction which makes it so pleasant as well as so profitable. A good clinical teacher is himself a Medical School. We need not wonder that our young men are beginning to announce themselves not only as graduates of this or that College, but also as pupils of some one distinguished master.
I wish to close this Lecture, if you will allow me a few moments longer, with a brief sketch of an instructor and pract.i.tioner whose character was as nearly a model one in both capacities as I can find anywhere recorded.
Dr. JAMES JACKSON, Professor of the Theory and Practice of Medicine in this University from 1812 to 1846, and whose name has been since retained on our rolls as Professor Emeritus, died on the 27th of August last, in the ninetieth year of his age. He studied his profession, as I have already mentioned, with Dr. Holyoke of Salem, one of the few physicians who have borne witness to their knowledge of the laws of life by living to complete their hundredth year. I think the student took his Old Master, as he always loved to call him, as his model; each was worthy of the other, and both were bright examples to all who come after them.
I remember that in the sermon preached by Dr. Grazer after Dr. Holyoke"s death, one of the points most insisted upon as characteristic of that wise and good old man was the perfect balance of all his faculties. The same harmonious adjustment of powers, the same symmetrical arrangement of life, the same complete fulfilment of every day"s duties, without haste and without needless delay, which characterized the master, equally distinguished the scholar. A glance at the life of our own Old Master, if I can do any justice at all to his excellences, will give you something to carry away from this hour"s meeting not unworthy to be remembered.
From December, 1797, to October, 1799, he remained with Dr. Holyoke as a student, a period which he has spoken of as a most interesting and most gratifying part of his life. After this he pa.s.sed eight months in London, and on his return, in October, 1800, he began business in Boston.
He had followed Mr. Cline, as I have mentioned, and was competent to practise Surgery. But he found Dr. John Collins Warren had already occupied the ground which at that day hardly called for more than one leading pract.i.tioner, and wisely chose the Medical branch of the profession. He had only himself to rely upon, but he had confidence in his prospects, conscious, doubtless, of his own powers, knowing his own industry and determination, and being of an eminently cheerful and hopeful disposition. No better proof of his spirit can be given than that, just a year from the time when he began to practise as a physician, he took that eventful step which in such a man implies that he sees his way clear to a position; he married a lady blessed with many gifts, but not bringing him a fortune to paralyze his industry.
He had not miscalculated his chances in life. He very soon rose into a good practice, and began the founding of that reputation which grew with his years, until he stood by general consent at the head of his chosen branch of the profession, to say the least, in this city and in all this region of country. His skill and wisdom were the last tribunal to which the sick and suffering could appeal. The community trusted and loved him, the profession recognized him as the n.o.blest type of the physician.
The young men whom he had taught wandered through foreign hospitals; where they learned many things that were valuable, and many that were curious; but as they grew older and began to think more of their ability to help the sick than their power of talking about phenomena, they began to look back to the teaching of Dr. Jackson, as he, after his London experience, looked back to that of Dr. Holyoke. And so it came to be at last that the bare mention of his name in any of our medical a.s.semblies would call forth such a tribute of affectionate regard as is only yielded to age when it brings with it the record of a life spent in well doing.
No accident ever carries a man to eminence such as his in the medical profession. He who looks for it must want it earnestly and work for it vigorously; Nature must have qualified him in many ways, and education must have equipped him with various knowledge, or his reputation will evaporate before it reaches the noon-day blaze of fame. How did Dr.
Jackson gain the position which all conceded to him? In the answer to this question some among you may find a key that shall unlock the gate opening on that fair field of the future of which all dream but which not all will ever reach.
First of all, he truly loved his profession. He had no intellectual ambitions outside of it, literary, scientific or political. To him it was occupation enough to apply at the bedside the best of all that he knew for the good of his patient; to protect the community against the inroads of pestilence; to teach the young all that he himself had been taught, with all that his own experience had added; to leave on record some of the most important results of his long observation.
With his patients he was so perfect at all points that it is hard to overpraise him. I have seen many noted British and French and American pract.i.tioners, but I never saw the man so altogether admirable at the bedside of the sick as Dr. James Jackson. His smile was itself a remedy better than the potable gold and the dissolved pearls that comforted the praecordia of mediaeval monarchs. Did a patient, alarmed without cause, need encouragement, it carried the sunshine of hope into his heart and put all his whims to flight, as David"s harp cleared the haunted chamber of the sullen king. Had the hour come, not for encouragement, but for sympathy, his face, his voice, his manner all showed it, because his heart felt it. So gentle was he, so thoughtful, so calm, so absorbed in the case before him, not to turn round and look for a tribute to his sagacity, not to bolster himself in a favorite theory, but to find out all he could, and to weigh gravely and cautiously all that he found, that to follow him in his morning visit was not only to take a lesson in the healing art, it was learning how to learn, how to move, how to look, how to feel, if that can be learned. To visit with Dr. Jackson was a medical education.
