ROSEBRUGH, Abner Mulholland (rose-brew), Canadian physician, born near Galt, Ont., 8 November, 1835. He was educated at Victoria college, Toronto, and studied medicine in New York and London. He practised successfully in Toronto, and in 1863 revived the Free dispensary of that city, which had been closed for want of funds, establishing it upon a firm basis, and in 1867 he organized the Toronto ear and eye infirmary. He has devoted his attention to medical electricity and ophthalmology, and delivered lectures on the latter subject at Victoria college in 1870-'1. In 1864 he invented a new demonstrating ophthalmoscope, and in that year he photographed the living fundus oculi. In 1865 he photographed the inverted retinal image of an object placed in front of the eye. In 1878 he, in association with a friend, Mr. G. Black, anticipated Van Rysselberghe in rendering practical the simultaneous transmission of telephonic and telegraphic messages on the same wire. He has published "An Introduction to the Study of the Optical Defects of the Eye" (1866) ; "Chloroform and a New Way of Administering It" (New York, 1869); "A Hand-Book of Medical Electricity" (1885); and a pamphlet on " Recent Advances in Electro-Therapeutics" (1887).
