On the 4th August anchor was weighed at Manado, where the sufferers from fever and dysentery had not got much better, and on the 29th of the same month the expedition arrived at Batavia where it only remained three days. The rest of the voyage of the _Astrolabe_ was in well-known waters. Mauritius was reached in due course, and there D'Urville met Commander Le Goarant, who had made a trip to Vanikoro in the corvette _La Bayonnaise_, and who told D'Urville that he had not attempted to enter the reef, but had only sent in some boats to reconnoitre. The natives had respected the monument to the memory of La Perouse, and had been reluctant even to allow the sailors of the _Bayonnaise_ to nail a copper plate upon it. On the 18th November the corvette left Mauritius, and after touching at the Cape, St. Helena, and Ascension, arrived on the 25th March, 1829, at Marseilles, exactly thirty-five months after her departure from that port. To hydrographical science, if to nothing else, the results of the expedition were remarkable, and no less than forty-five new charts were produced by the indefatigable Messrs. Gressien and Paris. Nothing will better bring before us the richness of harvest of natural history specimens than the following quotation from Cuvier's report:-- "They (the species brought home by Quoy and Gaimard) amount to thousands in the catalogues, and no better proof can be given of the activity of our naturalists than the fact that the directors of the Jardin du Roi do not know where to store the results of the expedition, especially those now under notice. They have had to be stowed away on the ground-floor, almost in the cellars, and the very warehouses are now so crowded--no other word would do as well--that we have had to divide them by partitions to make more stowage." The geological collections were no less numerous; one hundred and eighty-seven species or varieties of rock attest the zeal of Messrs. Quoy and Gaimard, while M. Lesson, junior, collected fifteen or sixteen hundred plants; Captain Jacquinot made a number of astronomical observations; M. Lottin studied magnetism, and the commander, without neglecting his duties as a sailor and leader of the expedition, made experiments on submarine temperature and meteorology, and collected an immense mass of information on philology and ethnography. We cannot better conclude our account of this expedition than with the following quotation from Dumont d'Urville's memoirs, given in his biography by Didot:--
