Bartholin. I. Kaspar, a Danish physician and savant, born at Malmo, Sweden, Feb. 12,1585, died in Copenhagen, July 13,1629. He taught medicine in Basel, practised at Wittenberg, and was successively professor of rhetoric, medicine, and theology at the university of Copenhagen. His principal work, Institutiones Anatomicm (Wittenberg, 1611), has passed through several editions and been translated into foreign languages. II. Thomas, son of the preceding, born in Copenhagen, Oct. 20, 1616, died at Hage-sted, Dec. 4, 1680. He was a physician, professor of mathematics, and for 11 years of anatomy, in Copenhagen, and finally became physician to the king, director of the university library, and adjunct judge of the supreme court. He is especially distinguished as the reputed discoverer of the lymphatic system of vessels, though the priority in this matter was contested by Olaus Rudbeck of Sweden. His works were very numerous, the most important being Be Lacteis Thoracis in Homine Brutisque (Copenhagen, 1652), and Vasa Lymphatica nuper Hafniae in Animalibus inventa et in Homine, et Hepatis Exequice (1653).
