Falconer, Hugh (1809-65): was a student at the Universities of Aberdeen and
Edinburgh, and went out to India in 1830 as Assistant-Surgeon on the Bengal
Establishment. In 1832 he succeeded Dr. Royle as the Superintendent of the
Botanic Gardens at Saharunpur; and in 1848, after spending some years in
England, he was appointed Superintendent of the Calcutta Botanical Garden
and Professor of Botany in the Medical College. Although Falconer held an
important botanical post for many years, he is chiefly known as a
Palaeozoologist. He seems, however, to have had a share in introducing
Cinchona into India. His discovery, in company with Colonel Sir Proby T.
Cautley, of Miocene Mammalia in the Siwalik Hills, was at the time perhaps
the greatest "find" which had been made. The fossils of the Siwalik Hills
formed the subject of Falconer's most important book, "Fauna Antiqua
Sivalensis," which, however, remained unfinished at the time of his death.
Falconer also devoted himself to the investigation of the cave-fauna of
England, and contributed important papers on fossils found in Sicily,
Malta, and elsewhere. Dr. Falconer was a Vice-President of the Royal
Society and Foreign Secretary of the Geological Societ
