He came to New York, where he remained five years, and on his return was made a senator by Consul Bonaparte in 1803. Demennier is the author of "Voyages de Vancouver"; "Esprit des usages at des coutumes des differents peuples" (3 vols., 1776'80); "Essai sur les etats unis" (1786): and " L'Amerique independante" (4 vols., 1790).
