CHRISTY, HENRY (1810-1865), English ethnologist, was born at Kingston-on-Thames on July 26, 181o. From 1850-58 he travelled in Europe and America, studying ethnology. In 1858 the discoveries by Boucher de Perthes of flint implements in France and England were first held to have proved the great antiquity of man. Christy joined the Geological Society, and with his friend Edouard Lartet explored the caves in the valley of the Vezere. An account of the explorations appeared in Comptes rendus (Feb. 29, 1864) and Transactions of the Ethnological Society of London (June 21, 1864). He died, on May 14, 1865, leaving a half-finished book, entitled Reliquiae Aquitanicae, which was issued in parts and completed first by Lartet and, after the latter's death in 187o, by Professor Rupert Jones. Christy left his magnificent archaeological collection to the nation. In 1884 it was placed in the British Museum.
