Deusingius, Anthony

, a learned physician, and voluminous writer on medicine and natural philosophy, was born at Meurs, in the duchy of Juliers, October 16th, 4612. After studying the classics and the Arabic and | Persian languages, he went to Leyden, where he completed his education by taking the degree of M. D. in 1634; and three years after was appointed professor in mathematics at Meurs. In 1639, he was called to succeed Isaac Pontanus in the chair of natural philosophy and mathematics; and in 1642 to that of medicine, at Hardenvick, to which was added the office of physician to the city. From Harderwick he went to Groningen, where he was not only professor of medicine, but rector of the university, and ancient of the church. Amid the business which such accumulated duties heaped upon him, he found leisure to write a greater number of treatises on the different parts of medicine and philosophy than have fallen from the pen. of almost any other man. Haller and Manget have given a list of fifty-four, but a small number of these are on practical subjects, many of them being metaphysical and controversial. Those relating to his controversy with Silvius, are written with great acrimony; though the subjects, which are mostly physiological, do not seem calculated to excite so much rancour as we see infused into them. Among these are, “Joannes Cloppenburgius, Heautontimorumenos, seu retorsio injuriarum de libello falsidico, cui titulus, Res judicata, cumulatarum,1643, 4to. The subject of dispute is the nature of the soul, and on the intelligences that direct the course of the stars.

Canticum Avicennas de Medicina, ex Arab. Lat. reddit.1649, 4to. “Dissertationes duae, prior de motu cordis et sanguinis, altera de lacte ac nutrimento foetus in utero,1651, 4to.- In this he defends the circulation of the blood, as described by our countryman Harvey. “Synopsis Medicine universali?,1649, &c. Deusingius died in the winter of 1666, of a pleuritic affection, occasioned by taking a long journey, in very severe weather, to visit the count of Nassau, to whom he was physician. 1
