spirit of research which alone makes teaching " high " ; and during 

 the rather less than a score of years which made up his stay at Balti- 

 more, he produced a very marked effect on American science, fully 

 working out the great aim of the University which had adopted him. 

 By himself, or in concert with his pupils, he carried on many im- 

 portant investigations, among which may especially be mentioned 

 those on the excised mammalian heart. He was the first to show 

 that by appropriate methods the excised mammalian heart may be 

 made the subject of prolonged study. One of these researches, 

 namely, that on the " Influence of Temperature," was made the 

 Croonian Lecture of 1883. His various contributions were, in 1895, 

 republished in a collected form by his friends and pupils in America, 

 under the title of "Physiological Papers." He sent out into the 

 States, from among his students, a number of trained physiologists, 

 fired with his own enthusiasm, who are continuing to advance the 

 science, and one of whom has succeeded him at Baltimore. He also 

 found time to write expository works, and his ' Human Body,' 

 ' Briefer Course,' and ' Elementary Course,' deservedly became very 

 popular in the States. 



Upon his first appointment he had the charge of the whole subject 

 of animal biology ; and since he was himself more distinctly a 

 physiologist, it was almost his first duty to secure or train up a 

 colleague who should devote himself to morphology. Martin early 

 saw the worth of one of his students, W. K. Brooks; to him he 

 gradually entrusted morphological matters, and thus prepared, not 

 only the way for a separate Chair of Zoology, but also the man to 

 fill it. 



Martin married in 1879 Mrs. Pegram, the widaw of an officer in 

 the Confederate army ; but there was no issue, and in 1892 his wife 

 died. 



Even before his wife's death his health had begun to give way ; 

 and after that event he became so increasingly unfitted for the duties 

 which his own previous exertions had raised to a very great import- 

 ance, that in 1893 he resigned his post. 



After his resignation he returned to this country, for he had never 

 become an American citizen, and was looking forward to being able, 

 with improved health, to labour in physiological investigations, hither 

 at his old University or elsewhere in England. But it was not to be. 

 Though he seemed at times to be improving, he had more than one 

 severe attack of illness, and never gained sufficient strength to set 

 really to work. During the past summer he visibly failed, and while 

 he was striving to recover his strength by a stay in the quiet dales of 

 Yorkshire, a sudden haemorrhage carried him off on October 27, at 

 Burley-in-Wharfedale, Yorkshire. 



Having been for so long a stranger to this count ry, Martin was,
