Of North Carolina, filled the chair of Theory and Practice in Transylvania in the sessions of 1844 and 1845 only. He came highly recommended as a physician of extensive practice of not less than twenty years. "A gentleman of undoubted talents. He has the reputation of bringing to his cases a great affluence of resource and fertility of expedient, regulated by a judgment discriminative and safe. He writes with facility and elegance, and converses with fluency, animation, and impressiveness. He thinks clearly and communicates his ideas with facility and a corresponding clearness." Extract from letter of Senator W. P. Mangum, of North Carolina. LEONIDAS M. LAWSON, M. D., Who filled the chair of General and Pathological Anatomy and Physiology in the Medical Department of Transylvania University from 1843 to 1846, inclusive, was born in Nicholas County, Kentucky, September 10, 1812. He had received his medical degree from this same department of Transylvania in 1837. He was engaged in Cincinnati in private practice, giving clinical instruction in the hospital and editing his recently established medical periodical, _The Western Lancet_--of which he was sole originator and proprietor--when he was called to the newly established chair of General and Pathological Anatomy and Physiology in the Transylvania Medical Department, in which he had graduated. Here he taught with great success until called to the chair of Materia Medica and General Pathology in the Ohio Medical College at Cincinnati in 1847. During the vacation months of 1845, he spent seven months in a visit to Europe, and especially in clinical studies in Guy's Hospital, London, with great advantage to himself. Doctor Lawson continued to teach from this chair until the death of Professor J. P. Harrison, whom he succeeded in that of the Principles and Practice of Medicine and Clinical Medicine, in the same college in 1852. He was appointed Professor of the Theory and Practice of Medicine in the Kentucky School of Medicine in Louisville in 1854, but accepted a call to the same chair in the Medical College of Ohio, Cincinnati, in 1857. He filled the chair of Clinical Medicine in the University of Louisiana, New Orleans, in 1860, but returned in consequence of the Civil War to the Medical College of Ohio the following year, in which college he remained until his death, January 21, 1864. He founded the _Western Lancet_, and was its sole editor and proprietor from 1842 up to the time of his decease. He also edited _Hope's Morbid Anatomy_, 1844, and published a treatise on the _Practical Treatment of Phthisis Pulmonalis_ in 1861.
