SENAC, JEAN BAPTISTE, called also by Haller, in his Bibliotheca Anatomica, Pierre, a distinguished French physician, was born in the diocese of Lombez in 1693. Having taken his medical degree at Rheims, he subsequently practised physic with great applause. He was made first physician to the king in 1752, and a member of the Royal Academy of Sciences of Paris. In addition to his contributions to the Mémoires de l'Académie, which began as early as 1824, he likewise published anonymously a Traduction of the Anatomie of Heister, with additional Essais de Physique sur l'Usage des Parties du Corps Humain, Paris, 1724, 1735, 1755, 3 vols. 12mo. His next work, which appeared under the assumed name of Julien Morrison, entitled, Lettres sur le Choix des Saignées, Paris, 1730, had great sale. His Traité de la Structure du Cœur, 2 vols. 1748, was regarded as his greatest work, and has been since published at Paris, with additions and emendations by M. Portal. He likewise published another book full of profound knowledge, De Recondita Februm Natura et Curacione, 1759.
