ADDRESS TO THE GKEt^IDTTuSkTIIXrG- CLASS OF THE MEMPHIS MEDICAL COLLEGE BY C. T. QUINTARD, M. D, PROFESSOR OF PHYSIOLOGY AND PATHOLOGY. SESSION OF 1854-5. There are moments in life so macle up of mingled emotions that it is difficult to analyze them-to know whence they draw their interest-whether it be from the half-forgotten past, or the realizations of the present-moments when the lips refuse to utter, what the heart is laboring to disclose, and when silence is indeed a balm to the soul. Utterly unable to tell what feeling is predomi- nant in my heart, or to find words with which to portray my emotions, I should willingly give place to another who would speak words of wise counsel and kindly encouragement to you, gentlemen, who have just been made members of a learned, and liberal, and venerable profession. I can scarcely realize that this is the last opportunity that I shall ever have of appearing before a medical class. The time is so short, since, like you, I was struggling for the honors which have been conferred on you, and since I felt the flush of joy which you now feel, that I can yet recall the absorbing happiness of that moment. Eight years have rolled away since I received the doctorate. I started out in life with many an expectation-which was never to be realized-with many a hope springing into life only to be blighted. I found the world, and life, and duty, much more matters of fact than of fancy. I found that there was something to struggle with and something to labor for-that life was full of high and holy duties -that sorrow flung a shadow over the heart, and that even re- morse was no stranger to the soul of man. I found the silver current of life winding among rocks, now shooting out into the sunlight, and anon whirling among shifting sands in darkest 2 ADDRESS TO THE GRADUATING CLASS OF TIIE shades. I found that those succeeded best who soonest realized the responsibilities of living-and that earnest labor always brought its own recompense. These things I had thought upon before-but had not considered them as matters of much moment. They were clouds flitting athwart the horizon and soon cleared away. And you, gentlemen, though you cannot feel this now, will surely feel it hereafter. You will find more thorns than flowers in your path. Like Adam, when driven from Eden, you will find thorns and thistles springing up everywhere about you, and the sooner you realize the duties which devolve upon you, the more earnestly you set yourselves to the task which is before you, the sooner you will find the thorns and thistles trodden down, and pleasant flowers springing up in their places. You have arrived at a period in life when all is bright with anticipation, redolent of hope, and glowing with the deepest interest. Let your anticipa- tions, your hopes, and all your interests, rest upon the firm basis of virtuous principle, that when the lapse of time shall leave this season of pleasant association in the distance, memory may clothe it with her richest and loveliest drapery. The diplomas which you have just received, you must regard as certificates of admission into the profession of medicine. They carry with them no guarantee of success apart from earnest and laborious effort, and wdiile they are tokens of honor, you must look upon them as rather conferring the right to investigate more fully, to study more closely, and to apply more diligently the great principles of medical science, than as testimonials of the progress you have already made. I trust you intend to continue students some -while longer. If you devote your whole lives to study, you will have scarce time to master more than one branch of the great science of medicine-and yet the wonderful improvements which have been made in that science, the progress which the last century has witnessed, should encourage you to unremitting diligence. This is true not of one alone, but of every department, contin- gently or remotely connected with the science or art of medicine. Let me mention very briefly some of the changes which have taken place in modern times, changes which are not innovations merely, but radical improvements. Before Harvey discovered the true circulation of the blood, the opinion prevailed Universally, that the blood was formed in the liver, and sent out from it by all the veins to nourish the body, proceeding outwards during the day, and returning by night. These notions had become great and important doctrines, and had descended to the profession from their oldest teachers, with many weighty dependencies, conclusions and rules of practice ; they were as articles of faith which it was a heresy to forsake.* But when once the doctrine of Harvey had prevailed and dis- pelled the idle dreams which haunted men's minds about humors ♦John Bell. 3 and temperaments and blood, of the blood concocted in the liver, of the veins alone carrying proper blood while the arteries carried air only or vital spirits to animate the system by mixing with the blood, physicians found all their previous reasoning confounded and their theories, embracing the whole body of phy- sic, disturbed. They were forced to adopt new theories in order to explain the phenomena of health and disease. Where previous- ly they had imagined air, there was found pure blood. The circulation was found to be a circulation-the liver lost the greater part of its importance, and parts which had previously been considered scarcely worthy of regard were at once brought into conspicuous positions in the rapidly formed theories of the day. Doctrines not less erroneous than those they displaced were adopted, and as a consequence erroneous theories and practices were followed. What may be called the globular doctrine main- tained by the principal writers of the day, and dilated into ingenious but hypothetical theories, was received with great favor. This consisted chiefly in the maintenance that the blood was composed of globules, the larger globules of smaller ones, and then again of a third series-that the blood vessels were so proportioned to the size of the blood globules, and these so nicely adjusted to the variable size of the vessels, that each vesselj selected its proper globules; that when, by too violent an action, the larger globules were forced into the small vessels they produced either local inflammation or general disease.* Subsequently, physicians attempted to measure the force of the heart, the strength of the vessels, and the power of the various organs of the body, by mathematical processes. These mathematical physicians were famous in their day, and the names of Bellini, Pitcairne and others gave strength and lustre to the deductions of many a lesser light. While engaged in studying the various branches of medicine, Pitcairne devoted a portion of his time to the study of mathematics, by the applica- tion of which he believed much light might be thrown on many of the phenomena of life. Thus the process of digestion, explained as it then was by mechanical action, was accurately measured by Pitcairne, who conceived the food to be ground down by a pres- sure equal to a weight not less than a hundred and seventeen thousand and eighty pounds, assisted at the same time, in its gigantic labor, by an equal pressure derived from the surrounding muscles. Mathematical problems soon lost favor, and the theories of Pitcairne being less agreeable than other and newer doctrines, which were being received into favor he resigned his professor- ship at Leyden, which he had held but little over a year. From the discoveries which chemists had made while search- MEMPHIS MEDICAL COLLEGE. *For an account of these doctrines see the earlier editions of John Bell's work on Anatomy. 4 ADDEESS TO THE GEADUATING CLASS OF THE ing in the inorganic world for the philosophers stone, and " a perfect medicine for bodies that be sick," they pushed their inves- tigations into the various departments of medicine. " Having analyzed the materials of the druggists, the chemists proceeded to analyze the parts of the human body to which those medicines were to be applied, but from this rational commence- ment, followed one of the most trivial of all the miserable doc- trines with which our science has been disgraced; for as the chemists had already explained the properties of the salts, metals, earths, and of all active substances, by the angles, cubes, or other forms which they saw their particles assume, they soon persuaded themselves that such forms as cubes, wedges, spiculse, &c., exist- ed in the blood; and acid and alkaline humours, sharp, corrosive, irritating and pointed particles, were the terms in which they ex- pressed their most admired theories; and acids, alkalis, and metals, and medicines for rounding the pointed particles or obtunding (as they termed it) or sheathing or covering the acrimonious humors, were their chief preventives and cures."* Boerhaave united the mechanical hypothesisf with the chemical. He supposed many morbid phenomena to arise from acrimony of the blood which it was the business of the physician to neutralize. In his " Insti- tutions et aphorismes " he treats of the aids which art affords to medicine and details the system on the principles of the chemico- mechanical doctrine. It was the most comprehensive view that had yet been taken of medicine as a science, a model of erudition and method, embelished rather than encumbered by his opinions on the acrimony of the fluids, and his mechanical and hydraulic theories.J From this brief glance at some of the general doc- trines which were entertained by medical philosophers, a century or so ago-let us turn to the particular departments of medical science, and note a few of the improvements which have been made. In general anatomy our knowledge has been so extended, and rendered so comprehensive as almost to perfect the science. It has influenced in a wonderful degree the cognate sciences. Physiology is built upon it. In the first place it is the object of anatomy to ascertain structure; it is the object of physiology to ascertain function. An organ is constructed in such a manner as to fit it to perform a certain action; that action cannot be under- stood unless the structure is known; and often that structure can- ♦John Bell. fHe had been a pupil of Pitcairne. | " Boerhaave was the most remarkable physician of his age, perhaps the greatest of modern times ; a man who, when we contemplate his genius, his erudition, and singular variety of his talents, his unfeigned piety, his spotless character, and the impress which he left not only on contemporaneous prac- tice, but on that of succeeding generations, stands forth as one of the bright- est names on the page of history, and may be quoted as an example not only to physicians, but to mankind at large. " MEMPHIS MEDICAL COLLEGE. 5 not be known without directly leading to a knowledge of the action. Until the art of anatomy began to be cultivated, the science of physiology was without existence. In proportion as anatomy has been practiced, physiology has advanced, and these two, anatomy and physiology, are now the basis of the science of medicine. Comparative anatomy, by which term -we understand the science which conveys to us a knowledge of the differences in the structure and organization of the whole animal kingdom in all its classes, orders and species, though scarcely a half century has elapsed since the first attempts were made to systematize its almost infinite details, has furnished the most important aids to the study of human anatomy and physiology, and has supplied a secure and broad foundation for all zoological knowledge, both as regards existing and extinct races. This progress in anatomical science has rendered almost useless to the medical student the text books published half a century since. Even the work of John Bell, which was first published in 1793, and justly esteemed the best work of the day, is scarcely ever consulted, and yet John Bell was an accurate anatomist and a polished writer, and in his work is to be found none of that tedious interlarding of technical terms, that studied harshness and obscurity of anatomical descrip- tion, which was so much in vogue at the time he wrote. The skill of more recent anatomists, aided by physiological knowledge, has explained those delicate and obscure parts of anatomy which fifty years ago were quite unknown. With this improvement in anatomical knowledge, there has been a like improvement in the science of Surgery. Without an accurate knowledge of the structure, situation and relation of organs, the surgeon cannot proceed a single step in the practice of his art without the most imminent peril. It has been justly stated that no one can form an adequate conception, but those w'ho have witnessed it, of the confusion and terror occasioned by the sight of a human being from whose body the blood is gushing in torrents, and which none of the spectators are able to relieve- and it is impossible to conceive the situation of a medical man who knows not what to do in such an emergency. Yet ancient surgeons were constantly placed in this situation. Not only were they prevented, through terror, from interfering with the most painful and destructive diseases, which experience has proved to be capable of safe and easy removal, but in general, they were afraid to cut the most trivial tumor. They never thought of amputating until the limb had mortified and the dead had sepa- rated from the living parts ; being ignorant of the means of stop- ping hoemorrhage-they were afraid to cut into the living flesh. In his treatise on the Operations of Surgery-by Samuel Sharp, Surgeon of Guy's Hospital-published in 1751,* the writer says *Sixth edition, London, 1751. 6 ADDRESS TO THE GRADUATING CLASS OF THE " I have laid it down as a rule, that the mortification should not only be stopped but advanced in its separation; the reason of which is, that though the blood is so much altered for the bet- ter, as to occasion a stoppage of the gangrene, yet at this point of alteration, 'tis still in a bad state, and should be left to mend, with the utmost tranquillity of body and assistance of cordial medicines, until such time as granulations of flesh upon the living part of the extremity show the balsamic disposition of the blood." * If we compare this work with our college text books we find a vast improvement, not only in the operations of Surgery -but in surgical pathology. The writer tells us-" In the description of diseases I have only mentioned their distinguishing appearances, and have not once dared to guess at the particular disorder in the animal economy which is the immediate cause of them."f He did not "dare to guess"-he was quite unac- quainted with structural and relative anatomy. lie possess- ed none of that accurate knowledge which has since guided our great surgeon-Dr. Mott-in those formidable operations which have placed him at the head of the now living operators. Dr. Sharp gives the method of extirpating the tonsils by liga- ture. The best manner of applying the ligature "by means of an instrument of Mr. Cheselden's contrivance, which holds one end of the string on the side of the tonsil next to the throat, while you make a knot by pulling the other with the right hand quite out of the mouth. " He tells us how patients were prepared "for inoculation, " which had been introduced into England about thirty years previous to the publication of his work, and which was then universally had recourse to. Since the discovery of vaccination by Jenner, this operation has deservedly fallen into disuse, for whatever were the merits of inoculation in lessening the severity of Small-pox in the persons inoculated, it was on the whole productive of more harm than benefit, by introducing the disease, as it often did, into districts previously free from contagion. But consider the progress which has been made in Chemistry during the period of which we speak. Not simply in the dis- covery of gases and alkalis and metals, but the remedies which it has given us in an eligible form-its assistance in diagnosis- the light which it sometimes throws on the action of remedial agents-and its application to many of the arts of life. A century has not passed since Cavendish discovered and described the properties of " inflammable air, " since called hydrogen gas-the proportions of the constituent gases of the atmosphere and the composition of water. On the 1st of August, 1774, Priestly discovered what he called " dephlogisticated air, " now called oxygen gas. This discovery has served as a basis *Page 215. ■fOp cit-Preface. MEMPHIS MEDICAL COLLEGE. 7 for all that is known respecting the nature of the atmosphere, water, acids and alkalis. Uis work entitled "Experimentsand Observations on different kinds of Air, " contains a vast number of experiments from which various inferences might be drawn, ■which he seems, in his rapid career of discovery, to have over- looked.* But I should weary your patience were I to attempt to men- tion even the discoveries of Bergman, of Scheele, of Lavoisier, Berthollet, Guyton, Morveau, Fourcroy, Klaproth, Vauquelin, Wollaston, Davy, and others who have assisted in bringing the science to its present degree of perfection. I will mention only one or two discoveries which have been most important. The doctrine of definite proportions, founded on well ascer- tained facts, has bestowed on modern chemistry an almost math- ematical degree of precision. " Dalton," says Sir Robert Kane, " in promulgating the law of multiple combination, the most beautiful, as well as the most extensive principle that had been conferred on Chemistry since the epoch of Lavoisier, announced it as the result of speculations which, though in their general nature true, and constituting still the essential basis of all theories of chemical action, were yet overlaid by a tissue of hypotheses so irregular and so unnecessary, that for a long time the real dig- nity and excellence of the experimental laws were underrated and misunderstood. These accessory speculations have now, however, passed away, and the theory of combination laid down by Dalton may, in all its essential conditions be stated as follow's: all substances are supposed to be constituted of particles perfectly indivisible, and hence called atoms. In different kinds of matter these atoms are of different weights, and probably of different mag- nitudes ; but this latter quality is of no material interest. When bodies combine chemically, their combination must be so effected that one atom of one unites with one atom of another; or one of a first with two, three, or four of the second; or two of the first with three, or five, or seven, of the second; but no intermediate degrees can possibly occur, for the one atom being absolutely indivisible, no intermediate degree of union can take place." f The earliest experiments which could have served as a basis for the atomic theory are those of Wenzel, who, in 1777, published a work " On the affinities of Bodies." The author showed that when any two neutral salts decomposed each other, the resulting new compounds were exactly neutral. " The very attempt," remarks Dr. Thomson in his Ilistory of Chemistry, " to analyze the salts was an acknowledgement that bodies united with each other in definite proportions; and these definite proportions, had they *A portion of Dr. Priestly's apparatus for experimenting on gases is now- in the Labratory of the Memphis Medical College, together with portions of the apparatus of Sir Humphrey Davy, and Dr. Franklin. fElements of Chemistry-page 217. 8 ADDRESS TO THE GRADUATING CLASS OF THE been followed out, would have ultimately led to the doctrine of atoms." Although the atomic theory as developed by Dalton in 1808 contained truths of the highest importance, it was not until after the appearance of Dr. Wollaston's memoirs "On super- acid and sub-acid salts," and " On a synoptic scale of Chem- ical Equivalents," that chemists were fully impressed with the practical applications of which the theory was susceptible. Ber- zelius pointed out a number of numerical proportions in which different bodies combine so as to neutralize each other. Gay- Lussac discovered the important laws according to which chemists estimate the weight of the vapor of bodies which have never yet been separately vaporized. Sir II. Davy-Drs. Turner and Henry, Mr. Faraday, Mr. Brande, and others have made the matter so practical that it is now found to have important bear- ings on many of the arts. As Dr. Daubney remarks " it would be superfluous to enlarge upon the proofs already afforded with respect to the greater precision it has introduced into the science -the wonderful saving of time and labor which is derived from it-not only by the philosopher in his more speculative inquiries, but even by the manufacturing chemist, in the every-day opera- tions of his trade." * But Chemistry is of the most practical importance to the physi- cian. It has not only aided us in procuring new agents, but has so separated and changed others as to have greatly increased our resources. In 1803, Serteurner discovered in opium, the first of a new class of bodies, or the vegetable alkalis; this alkali is Morphia. In 1812, Iodine was discovered by M. Courtois, of Pafis. In 1818, Berzelius discovered a peculiar inflammable body, to which he gave the name of Seleneum. In 1824, he obtained the metalic basis of Silica and Zirconia, and in 1829, he found a new metal to which he gave the name of Thorium. In 1818, Stroymeyer discovered Cadmium, a new metal, and in the same year, Lithium was discovered by Arfwedson ; Bussy obtained Magnesium from its oxyde in 1829, and in 1830 Sefstrom discovered the metal Venadium. In 1823, Mr. Faraday showed that various gases which had previously resisted condensation might be rendered fluid. In 1826, Balard made known the new elementary body, Bromine. Thus one by one discoveries have been made, the full import of which cannot yet be calculated. In toxicological practice, Chemistry has become the almost exclu- sive guide. In the department of Materia Medica and Pharmacy, great improvements have been and still continue to be made; not only in the discovery of valuable remedies, but in the method of preserving them. In Obstetricy, " with the light afforded us through the investigations of modern obstetricians, w'e are enabled to surmount, by simple and harmless means, most of the incon- veniences and dangers attending a natural process which, however, ♦Introduction to Atomic Theory, page 87. MEMPHIS MEDICAL COLLEGE. 9 the excess of refinement-a consequence, perhaps, of the advance- ment of civilization and luxury, too often renders hazardous." * And all this improvement, has been of vast benefit to the hu- man family. It has not only rendered the life of man more happy by removing many annoyances and relieving him of many difficulties, but has actually increased the duration of human existence, for statistics prove that while in the 17th century, one- half of the population died under twelve years of age-at the beginning of the present century, one-half exceeded forty years. Such are some of the improvements and such the results which I offer, gentlemen, for your consideration and urge as reasons for diligence in the performance of the high duties which belong to the profession you have just now entered. You are not to suppose that all has been accomplished-that there are no fields of research courting your enquiries. " Excited, " says the vener- able Humboldt, " by the brilliant manifestations of new discoveries, and nourishing hopes, the fallacy of which often continues long undetected, each age dreams that it has approximated closely to the culminating point of recognition and comprehension of nature ." But you have only to look around you to see men reaching forward to higher and still higher discoveries. Nor can any one say what new discovery may change the tide of human affairs, " what hidden treasures may yet be brought to light, in the air or in the ocean, of which we know so little ; or what virtues there may be in the herbs of the field, or in the treasures of the earth; how far its hidden fires, or stores of ice may yet become available. Ages can never exhaust the treasures of natirre." But the profession of Medicine is not less benevolent than useful. Its members are ever ready to listen to the calls of the suffering, and every true physician holds his talents and attain- ments in trust for the puplic good. Consider the various insti- tutions of charity, the hospitals, asylums and dispensaries to which physicians contribute their time and talents, frequently without remuneration. It was my fortune, soon after entering the profession, to become attached to the Medical Staff of one of the largest hospitals in the United States, and during my term of service, three out of the number who composed that Staff, yielded their lives, a sacrifice to their humanity. Consider *Dr. F. Campbell Stewart. " Figures," he says, " on a large scale, fully establish the fact, that very great progress has been made in the practice as well as the theory of Obstetrics, and in confirmation of the assertion now made, I will state that I have collected the particulars of more than ninety thousand cases, embracing two periods. The first series comprises 47,116 cases, occurring between the years 1800 and 1825, in which instruments were used 430 times, or about once in on6 hundred. The second series is composed of 43,256 cases subsequently to 1825, 'and in these, instruments were resorted to only 252 times, or about once in two hundred."-Annivers- ary Discoubse before New York Academy of Medicine. 10 ADDRESS TO THE GRADUATING CLASS OF THE the number, who, during the last two years, Eave fallen at the post of duty in the fearful epidemics that have visited our South- ern cities, and tell me where you will find a body of men who more consistently and honorably and devotedly pursue so benev- olent a calling. And when we take into account, the personal charities-the relief which is carried by individual members of the profession to the hovel and the abode of suffering-the account swells up far beyond what the profession has credit for. In a recent oration, by Dr. Griscom, delivered before the New York Academy of Medicine, he proved that, without considering the bad debts of the profession-the personal cash gratuities in the medical attendance, medicines, etc., given by each individual in his private capacity-that the time, labor and medicines, gra- tuitously rendered to the poor of New York at the various hos- pitals, infirmaries and dispensaries, amounted, in the year 1853, to the enormous sum of $800,000. And then, top, it must not be forgotten, that all the discoveries and improvements in the Science are freely given for the benefit of the public with no patent rights to reward labors which have, oftentimes, been pur- sued unremittingly for years. In that admirable code of Ethics, put forth by the American Medical Association, and which is recognized by all Medical institutions and individuals of char- acter, it is declared to be derogatory to professional character for a physician to hold a patent for any surgical instrument or medi- cine, or to dispense a secret nostrum, whether it be the composi- tion or exclusive property of himself or others. For if such nos- trum be of real efficacy, any concealment regarding it, is incon- sistent with beneficence and professional liberality, and if mystery alone give it value and importance, such craft implies either dis- graceful ignorance, or fraudulent avarice." And what are the rewards for all this labor, this benevolence, this unstinted charity? Not always pecuniary, because, as a class, the practitioners of the healing art are actuated by motives far above pecuniary compen- sation. As has been most truly said, c the highest rewards of a medical practitioner must always spring from the conscientious discharge of his responsible duties, and it is to the monitor within that he must appeal whenever he seeks the highest incentive to the practice of his art. If this were not so. how discouraging would it be to see the worldly success, with which impudence and pretension too often meet; how the heart would sicken to see one whose whole life had been devoted to master the secrets of his profession, earning scarcely a decent support, while some plausible Dr. Dulcamara gulls the public with an elixir which gives life to his purse." * Let me urge you, gentlemen, who arc about to start in life as members of this useful and benevolent profession to bear about you at all times, in all places, and under all circumstances, a *R.

MEMPHIS MEDICAL COLLEGE. 11 sense of the dignity of your calling, and if. perchance, you see ignorance with brazen face, and quackery in golden robes sport- ing in the fickle sun light of popular favor, be not turned aside. Turn neither to the right hand nor the left, but pursue your call- ing without defiling your hands by the contact of quackery, wheth- er it be unmasked, or presented to you in the garb of a refined and transcendental philosophy. Yon need never fear lor the success of legitimate medicine. "The feeble sea-birds, blinded by the storms, On some tall light-house, dash their little forms, And the rude granite scatters, for their pains, Those small deposites that were meant for brains. Yet the proud fabric, in the morning sun, Stands, all unconscious of the mischief done ; Nay, shines all radiance o'er the scattered fleet Of Gulls and Boobies, brainless at its feet." The isms in medicine may, for awhile, succeed, but no sooner are they subjected to the trying ordeal of time, than they pass away. And let me tell you, gentlemen, that there can be pointed out no discovery in medicine which has proved lastingly benefi- cial to mankind, which has not been made by the regular members of the profession. And who has the real confidence of society ? The quack with elixir ? or the honest, upright physician, who follows the art as it has come down to him, from the worthies of old, acquiring more and more power to benefit mankind ? To whom do the poor resort ? On whom do the rich rely, when pestilence walketh in darkness, and the sickness destroyeth at noon-day ? I assert unhesitatingly and without the fear of contradiction, that public opinion awards to the regular medical profession, its unreserved confidence. In the cities of New York, Philadelphia, .Boston, Baltimore, Ilichmond, Charleston, Savannah, and New Orleans, out of six hundred and more physicians, employed in charitable institutions of a respectable character, scarcely a single individual has been elected, who is not an honorable member of the regular faculty. And who are they who compose the med- ical staff of our Army and Navy; who go forth to the battle fields, with brave hearts and wise heads, to minister to the suffering? Let me tell you there is not a member of either staff " who may not be regarded as an ornament to his calling, and not only regular in his practice, but punctilious in his observance of the rules of Ethics." I would have you, gentlemen, remember these things. I would have you bear in mind the fact, that in all the teachings which you have received within the walls of our Institution, a rigid adherance to the honor of your profession has been enforced. Let the remembrance stimulate you, in an honor- able career, and never fear for the success of your well-directed efforts. 12 ADDRESS TO THE GRADUATING CLASS OF THE Gentlemen of the Faculty-I cannot contemplate the severance of a connexion, which, during the past four years, has existed between us, without some degree of pain. For four years I have been associated with you on terms of that kindly intercourse which begets the warmest esteem and most affectionate regard, and 1. should do violence to my feelings, were I to neglect to return you my heartfelt thanks for the kind consideration which you have at all times exhibited towards me. Four years ago, I brought the weakness of my wisdom and the strength of my hope, and added them to your more matured wisdom and more subdued hope, in the effort to establish, in this rapidly growing city, a substantial School of Medicine. Success has crowned our efforts. True, we cannot point to great numbers of students, but we can congratulate ourselves on the evidences which our pupils have given of such positive attainments as will entitle them to the first rank in the profession. And you need ask no higher honor than that which will be reflected back upon you by such a class as you, this evening, send out into the world. It is upon the character of the instruction you afford, that your success depends. It is not spacious structures-nor magnificent apparatus-nor extensive libraries-nor a great crowd of students-it is not any nor all these that can ensure success. Though your apparatus is unsurpassed, and your appliances for practical teaching unrivalled, you have not looked for success from these, but rather, that you have made the quality of your instruction, such as will bear the test of time and render your alumni useful members of the profession. You have prepared them to cope successfully with the difficulties which are ever and always arising in the way of the physician. To your graduates, you may entrust, without fear for the result, the honor and character of your College. I say success has crowned your efforts. You have succeedel in establishing what you proposed-an institution, which should be recognized as every way worthy the regard of the profession; which should come up to the high standard of the present professional era, and maintain a character in consonance with the advancing spirit of the age. The difficulties which were in your way, have gradually disappeared. The plain, straight-forward, honest course has overcome all obstacles, and the avenues which are now rapidly opening, for communication to the North, South. East and West, and which will render this city more accessible than most other points where reputable Medical institutions are established, will add greatly to the numbers who will resort to you for instruction. The high moral character which your school has already acquired, as it has inspired, so it will secure, the confidence of the profession and the public. An institution which seeks popularity, on any other than the substantial basis of moral principles, though it may obtain notoriety, can never enjoy a lasting reputation. I congratulate you on the prospects that are before you. I COn- 13 gratulate you that you have secured, for the chair which I have so imperfectly filled, Rene La Roche, a man whose pro- fessional learning is only equalled by the sterling worth of his character; and I trust your future success will be equal to the merits of your school. You need ask nothing more. Gentlemen Graduates :-The unchanging kindness and respect you have exhibited towards me-the warm feelings of friendship which you have manifested for me, render it difficult for me to say farewell as I would. I would offer you words of encourage- ment, by pointing you to what has already been done-to what each day is doing, in the noble profession upon which you have entered, and urge you to mingle in the strife with stout hearts and diligent hands. I would urge you to unwearied study-to laborious investigation. Make use of all the means at your command ; nay, search for means for improvement. Let me tell you, in the language of Dr. La Roche, that "you will never succeed as physicians unless you read, and read a great deal on Medicine. No man ought to be so self-conceited as to suppose that, out of his own mere observations and reflections, he can, during a short term of existence, acquire what it has taken man- kind twenty-five centuries to learn concerning the nature of dis- eases and their cure. Such a thing is impossible and you will make an egregious mistake if you suffer yourselves to believe that you can ever become learned, useful, and successful physi- cians, unless you should give yourselves up to the reading of works on Medicine. " * You must gather knowledge from men as well as from books, and, gathering it from every source, store it up in your minds. You must not only read, but reflect upon what you read:- " For mind is not as merchandise, which decreaseth in the using, But liker to the passions of men, which rejoice and expand in exertion. " I tell you now, and time will prove how truly, that you must give yourselves to reading and reflection, and while I tell you there is labor, real work before you, I can, at the same time, assure you that your labors will bring their own reward. Assume to your- selves a manly independence, and go forth to meet the future- " Heart within, and God o'erhead." Above all, remember that this world is not your abiding place. Forget not that you are immortal beings, and that whatever of joy or sorrow you may meet with in life, look beyond them to eternity. Think upon this. Let your hopes ever be fixed upon this fact. It is the one great fact that must influence your career in time, as it will fix your destiny when time shall be no more. If you heed it not, life -will have no worthy aim, exist- MEMPHIS MEDICAL COLLEGE. * Vide Meigs on Childbed Fever, Letter of Dedication, page 4. 14 YELLOW FEVER. ence will prove a blank, reason will be utter foolishness, and hope worse than vanity.
