PORET DE BLOSSEVILLE, Jules Alphonse Rene (po-ray), Baron, French navigator, born in Rouen, 29 July, 1802; died in the Arctic ocean about February, 1834. He entered the navy as a volunteer in 1818, served in the West Indies and South America, and in 1883 was appointed commander of the brig "La Liloise" and sent to the Arctic ocean. Sailing from Brest in May, 1833, he visited Iceland and Greenland, where he made astronomical observations, and prepared a valuable chart of the western coast of the latter country. He had reached latitude 83º N. when he was imprisoned by the ice-fields, and sent news to France by a whaler. This was the last that was heard of him, and several French and English expeditions failed to find traces of him. The expedition of "La Recherche et l'Aventare" ascertained through Esquimaux that Poret advanced farther than latitude 84. N., and it is supposed that his death was similar to that of Sir John Franklin. His works include " Histoire des decouvertes faites e diverses epoques par les navigateurs" (Paris, 1826), and "Histoire des explorations de l'Amerique du Sad" (1832).--His brother, Viscount Benique Ernest, born in Rouen, 19 January, 1799 ; died in 1869 ; was the author or translator of several American novels, including "John Tanner, ou 30 annees darts les deserts de l'Amerique du Nord" (Paris, 1839).
