the older. There is no doubt that His per- 

 ceived in Mall rare personal and mental 

 qualities, as he confides to him not only 

 the subjects and trend of work, but his 

 larger aspiration in the wide domain of 

 anatomical research. In the light of the 

 relation there revealed one can surmise 

 the satisfaction and joy with which His, 

 had he lived, would have welcomed the 

 establishment of the Institute of Embry- 

 ology with Mall as the first director. 



In my task of presenting a fragment of 

 the personality of Mall as apparent to his 

 intimate friends and associates, I find my- 

 self embarrassed by the many memories 

 that crowd my mind. It is not easy to 

 select episodes. I love myself to think of 

 the period during which he lived, as did 

 the medical officers, in the Johns Hopkins 

 Hospital, for then we were almost con- 

 stantly together. The small, older group 

 of men — older, that is, than the internes — 

 saw much of one another. Mall, Frank 

 Smith, Thayer, Barker, and I met always 

 at dinner, frequently at breakfast and 

 luncheon, at the small table at the head of 

 the room. There was lively conversation 

 and much variety of theme; and not a 

 little good cheer. A small photographic 

 print still exists which pictures the group ; 

 it is chiefly notable for the good likeness 

 of Mall which it presents, showing him 

 as it does in one of his happiest moods. 



Mall returned to Baltimore as the first 

 professor of anatomy of the new medical 

 school. The physical conditions surround- 

 ing the launching of the medical school 

 were so simple as to be almost austere. 

 Aside from the hospital — a model of com- 

 pleteness at the time — the plan for housing 

 the new departments of the school we should 

 now regard as meager in the extreme. I 

 sometimes think that it may be well to 

 recall from time to time the simple begin- 

 nings out of which the great institution 



of the Johns Hopkins Medieal School arose. 

 The only additions made to the hospital 

 buildings to accommodate the departments 

 of anatomy, physiology, and physiological 

 chemistry and pharmacology, were two 

 stories added to the original small patho- 

 logical building erected as a mortuary for 

 the hospital and already housing the entire 

 pathological department. It was in the 

 upper, or fourth story, of that enlarged 

 building that the complex department of 

 anatomy took origin. 



Some one else, who traces the growth of 

 anatomy at the medical school, can tell 

 better than I can how ilall adapted the 

 limited space and facilities at his command 

 to the teaching of anatomy, histology, and 

 embrj'ology, and to the conduct of re- 

 search. There was no actual break in 

 the continuity of his own investigations, 

 and very soon after the medical classes were 

 taken in he began to produce the new work 

 which in a steady and increasing stream 

 has come out of the anatomical depart- 

 ment. 



There were not a few obstacles to be 

 overcome in getting the students' work 

 properly started. I recall the shifts he 

 was obliged to make to bridge over the 

 gaps in dissecting until human cadavers 

 became available. This period was for 

 Mall, in many ways, an anxious one. But 

 it was not long before this particular ob- 

 stacle was overcome, and because of the 

 improvements which he introduced in the 

 preservation of human cadavers, his lab- 

 oratory soon became the custodian of all, 

 the anatomical material employed for dis- 

 section and surgical instruction through- 

 out the city. 



The kind of teaching which Mall gave 

 to his students has been described; there 

 was no lecturing in his curriculum. He 

 had almost a horror of lectures in anatomy ; 

 the idea collided with his fundamental
