Bordeu, Theophilus De

, son to the preceding, was born Feb. 22, 1722, at Iseste in the valley of Ossan inBearn, and at the age of twenty, for his degree of bachelor in the university of Montpellier, where he was then a student, he held a thesis “De sensu generice considerate,” which contains the ground-work of all the publications he afterwards gave. Such early knowledge determined his professors to dispense with several acts usual before admission to practice. In> 1743, he was created M. D. at Montpellier, and two years after succeeded his father, as inspector of the mineral waters, and professor of anatomy. In 1747, he was made | corresponding member of the royal academy of Sciences at Paris, whither he soon after went, and where he acquired great reputation. Having taken out his licence in that city in 1754, he was appointed physician to the hopital de la charite. He died of an apoplexy, Nov. 24, 1776. A deep melancholy, occasioned by the flying gout, was the fore-runner of his end. He was found dead in his bed. One of the faculty, jealous of his fame, and who had tried to ruin him by a prosecution, said on the occasion: “I should never have thought he would have died in a horizontal position.” But a witty lady retorted by observing “that death was so much afraid of him, that he was obliged to catch him napping.” The facility with which he exercised his profession, his reluctance to give medicines, and his great confidence in nature, sometimes drew upon him the reproach that he had not much faith in medicine; but his doubts were so much the less blameable, as he was continually occupied in rendering the resources of his art more certain. He never disputed at all towards the latter end of his life, because probably he had disputed much to no purpose in his youth. Nobody knew better how to doubt, and he had little confidence in his own knowledge, and trusted with difficulty to that of others. Seeing the great number of courses of lectures in all branches of science, advertised every day, he observed once to a friend: “Will no one ever give a course of good sense?” As he expressed himself at times with rather too much acerbity on the merits of others, some of his professional brethren have called his own into question. His works, however, sufficiently attest his abilities. The principal are, 1. “Chylificationis historia,1742, reprinted at Paris, 1752, 12mo. with his “Recherches sur les Glandes.” He thought he observed a duct passing from the thyroid gland to the trachaea; an opinion which he repeats in another of his works, but without sufficient ground. 3. “Dissertatio physiologica de sensu generice considerate,” Monspelii, 1743, 8 vo; Paris, 1751, with his “Chylificationis historia.” 4. “Lettres contenant des essais sur l’histoire des Eaux minerales du Beam, &c. 1746, 12mo.” In these he treats of the properties of the waters, and of the geography of Beam. 5. “Recherches anatomiques sur la position des Glandes, et sur leur actions,Paris, 1751, 8vo. 6. “Recherches sur le pouls par raport aux crises,Paris, 1756, 12mo; in which he has gone much beyond Solano in his discrimination of | pulses, and beyond what can be followed in practice. 7. “Recherches sur le tissu mnqueux, et l’organecellulaire,Paris, 1766, 12mo. Haller accuses him of disingenuity in attributing to himself the discovery of some properties of the cellular membrane, which had been before described by him and others, but allows the work to have, on the whole, considerable merit. 1
