Bohn, John

, a physician of considerable reputation in the seventeenth century, was born at Leipsic in 1640, and began his studies there, and at Jena. In 1663 he travelled in Denmark, Holland, England, and France, and returned by the way of Swisserland in 1665. The following year he took his degree of M. D. and in 1668 was promoted to the anatomical chair at Leipsic. In 1691 he was appointed city-physician, and in 1691 professor of therapeutics. In 1700 he was dean of the faculty, and after a prosperous career, both as a physician and writer, died in 1718. His principal works are, 1. “De Alkali et Acidi insuificientia pro principiorum corporum naturalium. munere gerendo,” Leipsic, 1675, 8vo. 2. “Dissertations chemico-physicic,” ibid. 1685, 4to, 1696, 8vo. 3. “Meditationes physico-cheuiicte de aerisin sublunaria infiuxu,” ibid. 1678, 8vo; 1685, 4to. 4. “De duumviratu hypocliondrioium,” ibid. 1689, 4to. 5. “Observatio atque experimenta circa usum spiritns vini externum in hainorragiis” sistendis,“Leipsic, loS.'i, 4to. 6.” Exercitatioues | physiologicæ, ibid. 1680, 1686, 1697 and 1710, 4to. 7. “De officio medici duplici, clinini nimirum ac forensis,” Leipsic, 1689, 1704, 4 vols. 4to, a work of great merit. 8. “De renunciatione vulnerum lethalium examen,” ibid. 1689, 8vo, often reprinted. Bonn, although not arriving at the conclusions of more modern and scientific physicians, frequently approaches them through the medium of sound and experimental knowledge. These last mentioned works on medicine, as connected with legal evidence, are particularly valuable. 1
