Sir James Clark, a British physician, born at Cullen, Banffshire, Dec. 14, 1788, died at Bagshot Park, June 29, 1870. He studied medicine at Edinburgh, and received his degree in 1817, after which he travelled in France, Switzerland, and Italy, studying the sanitary institutions of those countries. He then settled in Rome, and practised there as a physician eight years. Returning to Edinburgh, he obtained a reputation as one of the most skilful physicians of that capital, especially in diseases of the lungs. In 1826 he settled in London, and became physician-in-chief of St. George's hospital, and consulting physician of the king, the queen of the Belgians, the duchess of Kent, and the princess Victoria. On the accession of Victoria to the throne he was chosen her physician in attendance, became physician in ordinary to the prince consort, and received the title of baronet. In 1832 he was elected a fellow of the royal society, and on the establishment of the university of London he was chosen to its senate.

Dr. Clark published "Medical Notes," made during his travels (1820); "The Sanitive Influence of Climate" (1829; 5th ed., 1856), which contains a clear and philosophical account of the climates resorted to by invalids, together with meteorological tables; and a "Treatise on Pulmonary Consumption" (1835).
