MACQUER, Pierre Joseph, brother to the former, was born at Paris the 9th of October, 1718, and died there February 16. 1784. He was a member of the Academy of Sciences, and professor of pharmacy; and was engaged in the Journal de Savans, for the articles of medicine and chemistry. With the latter science he was intimately acquainted. He had a share in the Pharmacopœia Parisiensi, published in 1758, in 4to. His other works are, 1. Éléments de Chimie théorique; Paris, 1749, 1753, 12mo; which have been translated into English and German.—2. Éléments de Chimie pratique, 1751, 2 vols. 12mo. These two works were republished together, in 1756, in 3 vols. 12mo. 3. Plan d'un cours de Chimie expérimentale et raisonnée, 1757, 12mo; in the composition of which he was associated with M. Beaumé. 4. Formulae Medicamentorum Magistralium, 1763. 5. L'Art de la Teinture en Soie, 1763. 6. Dictionnaire de Chimie, contenant la Théorie et la Pratique de cet art, 1766, 2 vols. 8vo; which has been translated into German, with notes; and into English, with notes, by Mr Kier. Macquer has, by his labours and writings, greatly contributed to render useful an art which formerly tended only to ruin the health of the patient by foreign remedies, or to reduce
Macquer reduce the professors of it to beggary, while they prosecuted the idle dreams of converting every thing into gold.
