MacBride, James (17S4-1817).

Equally well known as physician and botanist, James MacBride was born in Williamsburg County in 1784. He graduated from Yale in 1805 and afterwards studied medicine. Settling in Pineville, South Carolina, he prac- tised there for many years, but later removed to Charleston where he died of yellow fever in 1817, only thirty-three yet when he had already made a reputation as doctor and scientist. Botany attracted him most and his chief writings on this subject were con- tributed to the "Transactions of the Linnean Society" and elsewhere. His name has been embodied by Dr. Steph- en Elliott in the MacBridea pulchra, a genus found in St. Johns, Berkeley, South CaroUna, of which but two species are known to exist. Dr. Elliott also dedicated to him the second volume of his "Sketch of the Botany of South Carolina and Georgia" (1824).

Profoundly skilled in his profession and high in the confidence of his fellow- citizens he fell a victim to yellow fever as the result of fatigue and exposure, depriving Charleston of a good citizen and medical botany of a devoted student.

MacCallum, John Bruce (1876-1906).

Born in Dunnville, Ontario, Canada, June 10, 1876, he was the second son of Dr. George A. MacCallum of that town. After going as a boy to the local schools he went to Toronto where he graduated from Toronto University in 1896. In the autumn of the same year he went to Baltimore to begin studying medicine at the Johns Hop- kins Medical School, where he took his

M. D. in 1900. While a student there he carried out several investigations on anatomical subjects; the most im- portant of which was that on the archi- tecture of the ventricles of the heart. During this time, at the end of his third year of study, he began to show alarming symptoms of the lingering illness which caused his death, and his final year was interrupted by a pro- longed stay in the hospital. Neverthe- less, in the autumn after his graduation he was sufficiently well to accept a position as assistant in anatomy in the University, which he held for a year, during which time he completed other anatomical studies. That sum- mer he attempted to spend in Germany, but was again prostrated by his old illness and compelled to return to Canada where he spent the winter in the woods in the hope of regaining his health. There with no facilities of any sort he completed the translation and editing of Szymonowicz's "Histology." After a stay of two months in Jamaica and another summer on the northern lakes of Ontario, he again felt himself strong and in 1902 went to Denver where he thought to practice. He taught anat- omy in the Denver Medical School for a short time, but soon became disheart- ened and left it all to drift westward to California. There he was invited by Prof. Jacques Loeb to become his assis- tant in physiology and from his accept- ance of this post until his death his work in the new subject was most productive.

In 1905^ when he had become assist- ant professor of physiology in the University of California, he again fell ill and hurried east to Baltimore where he remained some time in the hospital. Afterwards another summer in Canada restored him but Uttle. Nevertheless, the
