DESHAYES, See also:GERARD See also:PAUL (1795–1875) , See also:French geologist and conchologist, was See also:born at See also:Nancy on the 13th of May 1797, his See also:father at that See also:time being See also:professor of experimental physics in the 1 See also:Cole Centrale of the See also:department of la Meurthe. He studied See also:medicine at See also:Strassburg, and afterwards took the degree of bachelier es leltree in See also:Paris in 1821; but he abandoned the medical profession in See also:order to devote himself to natural See also:history. For some time he gave private lessons on See also:geology, and subsequently became professor of natural history in the Museum d'Histoire Naturelie. He was distinguished for his researches on the fossil See also:mollusca of the Paris See also:Basin and of other See also:Tertiary areas. His studies on the relations of the fossil to the See also:recent See also:species led him as See also:early as 1829 to conclusions somewhat similar to those arrived at by See also:Lyell, to whom Deshayes rendered much assistance in connexion with the See also:classification of the Tertiary See also:system into See also:Eocene, See also:Miocene and See also:Pliocene. He was one of the founders of the Societe Geologique de See also:France. In 1839 he began the publication of his Traite elementaire de conchyliologie, the last See also:part of which was not issued until 1858. In the same See also:year (1839) he went to See also:Algeria for the French See also:Government, and spent three years in explorations in that See also:country. His See also:principal See also:work, which resulted from the collections he made, Mollusques de l'Algerie, was issued (incomplete) in 1848. In 187o the See also:Wollaston See also:medal of the See also:Geological Society of See also:London was awarded to him. He died at Boran on the 9th of See also:June 1875. His publications included Description See also:des coquilles fossiles des environs de Paris (2 vols. and See also:atlas, 1824–1837); Description des animaux sans vertebres decouverts clans le bassin de Paris (3 vols. and atlas, 1856–1866); See also:Catalogue des mollusques de See also:file de la See also:Reunion (1863).
