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

working out the great ain of the University which had adopted him
By himself, or in concert with his pupils, he carried on many im
portant investigations, amon 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 thesc 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,
nnder the title of "Physiological Papers." He sent out into the
States, from among his students, a number of trained physiologists,
fired with h own enthusiasmı, who are continuing to advance the
science, and one of whom has succeeded him at Baltimoro, He also
found time to write expository works, aud 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 subjoet of animal biology; and since he was himself more distinctly a physiologist, it was almost his first dnty to secure or train up a colleagne who should devote himself to morphology. Martin carly saw the worth of one of his students, W. K. Brooks; to him he gradually entrusted morphologicai matters, and thus prepared, not only the way for a separate Chair of Zoology, bnt also the man to fill it.
Martin married in 1879 Mrs. Pegram, the widow of an officer in the Confederate army; bnt therc was no issue, and in 1892 his wifc died.
Even before his wife's death his hcalth had begun to give way and after that event he became so increasingly unfitted for the duties which his own previons exertions had raised to a very great import- ance, that in 1893 he resigned his post.
After his resiguation he returned to this country, for he had never become an American citizen, and was looking forward to being able, with iproved health, to labour in physiological investigations, either at his old University or elsewhere in England. But it was not to be Though he seemed at times to be inproving, 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 hæmorrhage carricd him off on October 27, at Burley in-Wharfedale, Yorkshire.
Having been for so long stranger to this country, Martin was,
