Each professor lectured three times a week, and his ticket was fifteen dollars. During this session ill feelings arose between Doctors Dudley and Drake, leading to the duel between Doctors Dudley and Richardson already described.[26] Doctor Drake resigned his professorship and returned to Cincinnati at the end of this session, returning subsequently in 1823 to occupy the same chair, to resign it again in 1827. Professor Richardson did not lecture this session. He, not having yet received the degree of M. D., was allowed to be absent.[27] PROFESSOR WILLIAM HALL RICHARDSON Taught in the Medical Department of Transylvania until the time of his death in 1844, and was highly respected by his pupils as a practical teacher in his especial chair, notwithstanding he had not the advantage of early educational training. He was a man of great energy and of many admirable traits of character. His pupil, the late Lewis Rogers, M. D., in his address as President of the Kentucky State Medical Society in 1873, thus spoke of his old preceptor and friend: "Few men ever had nobler traits of character. He was warm-hearted, brave, and a sincere friend. I knew him from my earliest boyhood, and have passed away many happy and instructive hours at his magnificent home in Fayette County.[28] His hospitality was profuse and elegant. I listened to his public teachings as a professor with interest and care, because I knew he taught the truth as far as he possessed it. He was not scholarly or graceful and fluent as a lecturer, but he was ardent and impressive, sufficiently learned in his special branch, and had at his command a large stock of ripe experience. I honor his memory beyond most men I have known." In 1819, a new and brilliant era for the University, and for the Medical Department of Transylvania, was inaugurated by the appointment of Reverend Horace Holley, LL. D., to the Presidency of the University. Doctor Samuel Brown was recalled to the chair of the Theory and Practice of Medicine, which he retained until 1825. Doctor Charles Caldwell was induced to remove from Philadelphia, where he had an official connection with the University of Pennsylvania, and to accept the chair of the Institutes of Medicine and Materia Medica here, thus completing the organization with the existing professors, Benjamin W. Dudley and William H. Richardson, and the election of Reverend James Blythe to the chair of Chemistry. The celebrated naturalist, C. S. Rafinesque, was advertised to lecture on Botany and Natural History in this and the following year.[29] CONSTANTINE SAMUEL RAFINESQUE,[30]
