Charles Philippe Robin, a French physiologist, born at Jasseron, department of Ain, June 4, 1821. He studied in Paris, and won in 1844 a prize at the école pratique de médecine, where he established a museum of natural history and anatomy, for which he was deputed by Orfila to collect specimens on the coast of Normandy and in the island of Jersey. He took his degree in 1846, and in 1847 became professor of general anatomy, and in 1862 of the new department of histology in the faculty of medicine. He is regarded as the leader, if not the founder, of the school of microscopic physiology, and has greatly promoted anatomical, physiological, and pathological researches. Since 1864 he has edited the Journal de l'ana-tomie et de la physiologie. In 1866 he was elected to the academy of sciences. His works include Du microscope et des injections dans leur application à l'anatomie et à la pathologic (8vo, 1849; 2d ed., 1870); Tableaux d'ana-tomie (4to, 1851); Traité de chimie anato-mique et physiologique, normale ou patholo-gique, written by him jointly with Verdeil (3 vols. 4to, with atlas, 1853); Histoire naturelle des végétaux parasites (8vo, 1853); Anatomie microscopique (1868); and a series of Leçons on special subjects (1866-'7). With Littré he recast successive editions of Nysten's Diction-naire de médecine, and the 12th edition (1865) so thoroughly that at the request of Nysten's widow the tribunal of the Seine decided in 1866 to strike out her husband's name as its author.
