SAINTE CLAIRE DEVILLE, Charles, French geologist, born in the island of St. Thomas, West Indies, in 1814; died in Paris, France, 10 October, 1876. After having pursued the regular course of studies as out-door pupil at the Ecole des mines in Paris, he undertook a journey of scientific investigation at his own expense, and in 1839-'43 visited the Antilles and the islands of Teneriffe and Cape Verd. His geological exploration of Guadeloupe occupied more than a year, and he was engaged in it when the island was visited by the terrible earthquake of 1834. On his return to France he published his work on the Antilles, and on its appearance set out to explore southern Italy. For several years he acted as assistant to Elie de Beaumont, occupant of the chair of the history of inorganic bodies in the Colldge de France, and finally became his successor. Professor Deville was also deeply interested in meteorology, and established a network of meteorological stations over France and Algeria. He was elected a member of the Paris academy of sciences in 1857 in the place of Dufrdnoy, and promoted officer of the Legion of honor, 13 August, 1862. He published, among other works, "Voyage gdologique aux Antilles et aux iles Tdn6riffe et de Fogo" (7 vols., Paris, 1856-'64) and "Recherches sur les principaux phdnomdnes de mdtdorologie, etc., aux Antilles" (1861).--His brother, Henri Etienne, West Indian chemist, born in St. Thomas, 11 March, 1818; died in Paris, 9 July, 1883, studied in Paris, early acquired reputation for his chemical researches, and in 1851 was appointed professor of chemistry in the Normal school of Paris, which post he held tili 1859, when he was made professor in the University of Paris. He discovered the anhydrous nitric acid in 1849, a new method of mineral analysis in 1853, and from 1854 to 1865 devoted his labors principally to researches upon the new metal aluminium. He was also the first to make artificial diamonds, which he did at an enormous cost, and he discovered new properties of several metals. His works include "Md-moire sur les carbonates mdtalliques et leurs com-binaisons" (Paris, 1852)" "Memoire sur les trois 5tats moldculaires du silicium" (1855)" "Memoire sur la production des t empdratures elevces" (1856) ; " M6talhlrta'ie du platine et des m5taux que l'accom-pagnent" (1857); and "De l'aluminium, ses pro-pridtds, sa fabrication" (1859).
