FREYCINET, LOUIS CLAUDE DESAULSES DE French navigator, was born at Montelimar, Drome. In 1793 he entered the French navy. After taking part in several engagements against the British, he joined in i800, along with his brother Louis Henri Freycinet (1777-1840, who afterwards rose to the rank of admiral, the expedition sent out under Capt. Baudin in the "Naturaliste" and "Geographe" to explore the south and south-west coasts of Australia. Much of the ground already gone over by Flinders was revisited, and new names imposed by this expedition. In 1805 he returned to Paris, and prepared the maps and plans of the expedition ; he also completed the narrative entitled Voyage de decouverts aux terres australes (1807-16) . In 1817 he commanded the "Uranie," in which Arago and others went to Rio de Janeiro, to take a series of scientific observations. For three years Freycinet cruised about, visiting Australia, the Marianne, Sandwich and other Pacific Islands, South America, and other places, and, not withstanding the loss of the "Uranie" on the Falkland islands during the return voyage, returned to France with fine collections in all departments of natural history, and with voluminous notes and drawings. The results of this voyage were published under Freycinet's supervision as Voyage autour du monde sur les corvettes "l'Uranie" et "la Physicienne" . Freycinet was one of the founders of the Paris Geographical Society. (See La Geographie NI
