anterior and posterior roots of the spinal nerves in some frogs, and demonstrated the cross-sensibility of the spinal marrow by sections of its lateral halves in the guinea-pig. This was followed by a course to the physicians of the city. His next course was given in the Franklin Institute. About this time, also, Dr. John Hastings of the Navy gave some lectures on yellow fever, apropos of the then existing epidemic, based on his personal observations during the Mexican war. In 1859, Dr. S. W. Gross, while one of Dr. Agnew's demonstrators, gave courses on Operative Surgery and Surgical Anatomy, and again in 1866-67. In 1860, and for some time afterwards, Dr. John W. Lodge gave courses in Experimental Physiology in the summer, and on Urinary Pathology in the winter. In Obstetrics, Dr. J. M. Corse also lectured here. In 1864-67 Dr. J. M. Boisnot, and also, in 1865–66, Dr. J. Bernard Brinton, each gave courses in Operative Surgery.

Since I have had charge of the school, Dr. Isaac Ott has experimented on cocaïne and other poisons, and Dr. H. C. Wood, Jr., on the physiological action of the alkaloids of veratrum viride, until my landlord complained of the barking dogs with such energy that I was fearful of summary ejectment. I well remember, too, among other odors, the persistent, and it seemed almost imperishable, smell from a seal which Dr. Harrison Allen dissected here some years ago. Besides these, the following regular courses of lectures have been given here: on Obstetrics, Dr. F. H. Getchell and W. F. Jenks; on the Microscope, Dr. James Tyson; on Operative Surgery, Dr. Hodge gave independent courses, from 1868 to 1870, in the eastern building; on Bandaging and Fractures, Drs. J. Ewing Mears and O. H. Allis; on Physical Diagnosis, Drs. John S. Parry, O. P. Rex, Stanley Smith, and Hamilton Osgood; on Venereal Diseases, Dr. William G. Porter; on Ophthalmology, Drs. George C. Harlan, George Strawbridge, and W. W. McClure; and on Laryngoscopy, Dr. J. Solis Cohen. For a number of years, also, the Naval Examining

Board examined all their candidates for admission and promotion here.

Of the various quiz associations I have been able to learn but little beyond my personal knowledge. That which followed the Academy of Medicine I have already named. In 1837 Dr. E. G. Davis quizzed on all the branches himself, as I learn from an old circular, as also, at first, was Dr. D. D. Richardson's habit. Dr. Richardson's quiz lasted from 1860 to 1871, and in the last few years he was assisted by Drs. Boisnot, Cohen, and Witmer. He had as many as eighty pupils. From 1866-68, I quizzed with Drs. Duer, Dunglison, and Maury; 1868-69, with Drs. Warder, McArthur, Leaman, and Mears; and from 1869 to 1872 with Drs. Hutchins, Allis, Rex, Getchell, Leffman, and Loughlin. This winter Drs. Wilson, West, Greene, and Osgood occupied this room. From 1869 to 1871, also, the eastern building was occupied by the quiz of Drs. Willard, Curtin, Cheston, Jenks, Wilson, and Githens. Of these numerous medical men many have already attained distinction; the rest deserve it, and with years no doubt will win it.

The Janitors deserve a passing word. They have been mostly apostolic in name (as well as somewhat overobedient to the apostolic injunction to Timothy), for two Johns and two Jameses have occupied the post for some forty years of its history. One, whom most of the older graduates will remember, was here for about twenty-five years. Crabbed and cross, yet a favorite withal, versed in all subject-lore beyond his fellows, he was only once baffled. When the two buildings were rivals and subjects unusually scarce, a fresh cadaver was stolen from this building at night and conveyed across the roof to the other. Being too closely guarded for another Stygian journey back, and the offense not being indictable at law, even he was foiled. He alternated from being a whisky-barrel in the morning to a barrel of whisky in the evening, and it was always supposed that he

died of spontaneous combustion, like old Krooks in "Bleak House," till I learned lately that he stuck to his colors to the last, and died from drinking the alcohol from specimens.

Such, in brief, is the history of this now somewhat venerable school, and of the many teachers associated with it.* I can count eighty-five teachers who have won their spurs in its lecture-rooms, formed here their habits of thought, style of lecturing, methods of scientific research, and gained their early fame as writers and teachers, so that twenty-seven have become professors in sixteen medical colleges, here and elsewhere, and fifty-one hospital and clinical physicians, surgeons, obstetricians, etc., of distinction. Thirty-two books have been written or edited, eleven pamphlets and not less than thirty papers of value have been published by its various teachers. Its Assistant Demonstrators are too numerous for me even to mention. Its students I cannot trace. Most of

them are personally unknown to me. But this I know, that, spread all over the world, doing faithfully their daily work, in relieving the suffering, soothing the dying, helping the poor, assuaging the pestilence that walketh in darkness, improving the public health, advancing the domain of pure and applied science, teaching earnestly its results to thousands of eager students, who, in turn, will swell their noble ranks, promoting in general the moral and material welfare of mankind, some in lofty, some in lowly station, they will confess that here they first developed their scientific tastes and aspirations; here they were taught to look beyond the lower to the highest and noblest aims of our profession; here they first caught the inspiration that has made them what they are; and that they will think kindly of the dear old school and its faithful teachers, and it may be even drop a tear of regret when they learn that the Philadelphia School of Anatomy is only a thing of the vanished past.

OUR RECENT DEBTS TO VIVISECTION.*

[After a few introductory remarks appropriate to the special occasion the address continued as follows.]

Tone

10 one of these medical issues of the day I purpose to direct your attention at present-one as to which intense feeling, especially among women, has been aroused, -viz., the question of experiments upon animals.

Epithets and invective have been freely used, but, as befits the audience and the occasion, I shall endeavor to approach it in a perfectly calm and fair spirit, seeking to lay before you only one aspect of a many-sided question,-viz., the actual practical benefits it has conferred upon man and animals— a fact that is constantly denied, but which medical evidence proves to be incontestable.

I shall not consider the important older discoveries it has given us, but only those since 1850, almost all of which are within my own personal recollection. Even of these I must omit nearly all of its contributions to physiology and to pathology, though so much of our practice is based upon these, and confine myself to the advances it has enabled us to make in medical and surgical practice. I shall endeavor to state its claims with moderation, for an extravagant claim always produces a revulsion against the claimant, and is as unwise as it is unscientific.

Again it must be borne in mind that, as in nearly every other advance in civilization and in society, so in medicine, causes are rarely single, put generally multiple and inter

woven. While vivisection has been a most potent factor in medical progress, it is only one of several factors the disentanglement of which and the exact balancing of how much is due to this or to that are often difficult and sometimes impossible. Let me add one word more. All that I may say is purely upon my own responsibility. I commit the opinion of no one else to any view or any statement of fact.

Medicine in the future must either grow worse, stand still, or grow better.

To grow worse, we must forget our present knowledgehappily, an inconceivable idea.

To stand still, we must accept our present knowledge as a finality, complacently pursuing the well-worn paths; neither hoping nor trying for anything better-happily, again, an impossibility.

To grow better we must try new methods, give new drugs, perform new operations, or perform old ones in new ways; that is to say, we must make experiments. To these experiments there must be a beginning: they must be tried first on some living body, for it is often forgotten that the dead body can only teach manual dexterity. They must then be tried either on an animal or on you. Which shall it be? In many cases, of course, which involve little or no risk to life or health, it is perfectly legitimate to test probable improvements on man first, although one of the gravest and most frequent charges made against us doctors is that we are experimenting upon our patients.

man.

But in many cases they involve great risk to life or health. Here they cannot, nay, they must not, be tested first upon Must we, then, absolutely forego them, no matter how much of promise for life and health and happiness they possess? If not, the only alternative we have is to try them on the lower animals, and we would be most unwise-nay, more, we would be cruel, cruel both to man and to animals-if we
