The next link in the chain was furnished by the expedition commanded by Bruni Dentrecasteaux, who, while the hurricane of the Revolution was raging, was despatched (1791) to search for La Perouse. He made important discoveries on his own account,* (* Voyage de Dentrecasteaux, redige par M. de Rossel, Paris 1808; Labillardiere, Relation du Voyage a la Recherche de la Perouse, Paris 1800.) both on the mainland of Australia and in Tasmania; and though he found no trace of his predecessor, his own name is honourably remembered among the eminent navigators who did original work in Australasia. It was Dentrecasteaux's hydrographer, Beautemps Beaupre, whose charting of part of the southern coast of Australia was so highly praised by Flinders. The expeditions thus enumerated were all despatched before the era of Napoleon, and appreciation of their objects cannot therefore be complicated by doubts as to his Machiavellian designs. Bougainville's voyage, and that of Marion-Dufresne, were promoted under Louis XV, that of La Perouse under Louis XVI, and Dentrecasteaux's under the Revolutionary Assembly. Each was an expedition of discovery. Next came the expedition commanded by Nicolas Baudin, with which we are mainly concerned, and which was despatched under the Consulate. It will presently be demonstrated that it did not differ in purpose from its predecessors, and that there is nothing to show that in authorising it Bonaparte had any other object than that professed. But before pursuing that subject, let it be made clear that French exploring expeditions to the South Seas were continued after the final overthrow of the Empire.
