Two years afterwards he was admitted into the academy of sciences, and in 1708 h delivered lectures on chemistry in the royal garden. In 1710 he was appointed physician to the Hotel-Dieu, a post which he occupied during the remainder of his life.

He purchased the office of king’s physician in 1722; and in that capacity he accompanied the infanta of Spain on her return from France, whither she had gone with the view of being married to Louis XV. Soon after his return to Paris 'he was honoured by the queen of Spain with the title of her consulting physician. In 1731 he was appointed professor of chemistry in the royal garden, in the place of Geoffroy. At a subsequent period he became particularly attached to the establishment of the duchess of Brunswick, whom he frequently visited in the palace of Luxembourg; and he likewise obtained the patronage of the princess of Conti, in whose hotel he regularly passed a part of every day, and there composed several of the chemical papers which he read before the academy of sciences. These papers treat of the subjects of iron, of nitre, and some other salts, of vegetable and animal analyses, of the origin and formation of monsters, &c. He died on June 9, 1743, and the loss of him was much regretted; for to the mild and polished manners of the gentleman, he united great sincerity and constancy in his attachments, and sentiments of liberality and generosity in all his proceedings.
