From 1857 to 1359 lie was editor of the Buffalo Medical Journal, surgeon of Buffalo City Hospital, and professor of physiology and microscopical anatomy in the University of Buffalo. In 1859 he removed to New York with his father, and was appointed professor of physiology in New York Medical College. Be was professor of physiology in the New Orleans Medical College in 1860, and stud ied in Europe in 1860 and 1861. He was pro fessor of physiology and microscopic anatomy in Bellevue Hospital Medical College, New York City, from 1861 till this institution was consoli dated with the medical department of New York University in 1898, when he was appointed professor of physiology in Cornell University Medical College. lie was, in 1874, Surgeon-Gen eral of New York State. lie carried out exten sive experimental investigations in human phys iology, and made several important discoveries.

His principal works are: The Physiology of .11an (5 vols., 1866-74; 4th ed. 1888) ; Chemi cal Examinations of Urine in Diseases (5th ed. 1879); Effects of Severe and Protracted Mus cular Exercises (1871); Source of Muscular Power (1878); Text-book of Human Physiology (1875) ; Experiments Regarding a New Function of the Lircr, Separating the Cholesterin of the Blood and Eliminating it as Stereorin (1862); The Physiology of the Nervous System (1872): Mechanism of Reflex ferrous Action in Normal Respiration (1874) ; The Treatment of Diabetes Mellitus (1834); Manual of Chemical Examina tion of the Urine in Disease (1893); Stcrcorin and Cholesterminia (1897).
