Demours, Peter

, a French physician, but better known as an oculist, was born in 1702, and was the son of Anthony Demours, an apothecary at Marseilles, under whom he received the early part of his education, which was continued at Avignon, where he resided, until he had taken the degree of doctor, in 1728. He then removed to Paris, and was placed for two years under M. Du Verney, for the study of anatomy. On the death of Du Verney, he was associated with M. Chirac in the care of the cabinet of natural history, in the royal garden at Paris. Having bestowed niHch attention and many experiments on the structure of the eye, in 1741 he sent to the royal academy of sciences a memoir on the subject, in which he shews that the vitreous humour is of a cellular texture, and that the cells comii unicate with each other, circumstances which bad not been before observed. He now employed himself, almost exclusively, in attending to the diseases of the eye, and soon attracted so much notice as to be appointed oculist to the king. In 1767, he published “Retire q. M. Petit,” on the subject of a disease in the eyes, occurring in a patient who had been inoculated with the small-pox. As he had acquired a competent knowledge of the English language, he translated into French the Edinburgh medical essays, which he published at Paris, in eleven volumes, 12 mo, Baker’s Natural History of the Polypus, Hales’s account of a Ventilator, Ranby’s treatise of Gunshot Wounds, and several volumes of essays on medicine, and on natural history, taken frqm the Philosophical Transactions, which procured him to be elected one of the foreign members of the royal society. He had been before associated with the royal academy of sciences at Paris. Demours died June 26, 1795, aged ninety-three. 2
