Lakanal also presented a plan of organization of a National Institute, what is now the Institut de France, and was charged with designating the first forty-eight members, who should elect all the others. He was by the first forty-eight thus elected. Proscribed as a regicide at the second restoration, he sailed for the United States, where he was warmly welcomed by Jefferson. The United States Congress voted him five hundred acres of land. The government of Louisiana offered him the presidency of its university, which, however, he did not accept. In 1825 he went to live on the shores of Mobile Bay on land which he purchased from the proceeds of the sale of the land given him by Congress. Here he became a pioneer and planter. In 1830 he manifested a desire to return to his native country, and offered his services to the new government, but received no answer and was completely ignored. But two years later, thanks to the initiative of Geoffroy St. Hilaire, who was the means of his reëlection to the French Academy, he decided to return, and did so in 1837. He lived in retirement in Paris, where he occupied himself until his death in 1845 in writing a book entitled _Séjour d'un Membre de l'Institut de France aux États-Unis pendant vingt-deux ans_. The manuscript mysteriously disappeared, no trace of it ever having been found. (Larousse, _Grand Dictionnaire Universel_, Art. LAKANAL.) His bust now occupies a prominent place among those of other great men in the French Academy of Sciences. [30] This is seen to be the case by the title of the pamphlet: _Mémoire sur les Cabinets d'Histoire Naturelle, et particulièrement sur celui du Jardin des Plantes_. [31] Bourguin also adds that "on one point Lamarck, with more foresight, went farther than Lakanal. He had insisted on the necessity of the appointment of four demonstrators for zoölogy. In the decree of June 10, 1793, they were even reduced to two. Afterwards they saw that this number was insufficient, and to-day (1863) the department of zoölogy is administered at the museum by four professors, in conformity with the division indicated by Lamarck." CHAPTER IV PROFESSOR OF INVERTEBRATE ZOÖLOGY AT THE MUSEUM Lamarck's career as a botanist comprised about twenty-five years. We now come to the third stage of his life--Lamarck the zoölogist and evolutionist. He was in his fiftieth year when he assumed the duties of his professorship of the zoölogy of the invertebrate animals; and at a period when many men desire rest and freedom from responsibility, with the vigor of an intellectual giant Lamarck took upon his shoulders new labors in an untrodden field both in pure science and philosophic thought.
