In the summer of 1846, Doctor Ethelbert L. Dudley was appointed to deliver a course of lectures on Comparative Anatomy. This duty he performed to the highest satisfaction of all concerned; and when, almost at the beginning of the next regular session (1847-48), he was called to the chair of Anatomy and Physiology, he successfully encountered the great labor of preparing and delivering a new course of lectures on these subjects. At the same time he also discharged the arduous duties of Demonstrator of Anatomy--duties more onerous in this school, in our small inland city, than in most other medical colleges. No one in the whole school accomplished half the work which he mastered. No task seemed too great for his young and ardent energies. In 1849, he originated and took upon himself the sole charge as editor of the _Transylvania Medical Journal_, a new series of the old _Transylvania Journal of Medicine_. He published three volumes in three successive years, aided only occasionally by some of his colleagues. In the spring of 1850, he visited Europe for professional improvement, making many friends; amongst the distinguished medical men of England particularly. Immediately on his return from Europe, in the autumn of that year, the present writer announced to him, in the city of New York, his appointment to the chair of Descriptive Anatomy and Histology in the Kentucky School of Medicine. This was a new school which some of the physicians of Louisville and professors of the Lexington school were about to establish in the former city, to which place students of medicine from the South and West were beginning to flock, to the neglect somewhat of the time-honored Transylvania school, in which it was proposed to continue medical instruction in summer sessions. This appointment he accepted, joining in the preliminary October course of lectures and aiding greatly by his talents and energy in building up that institution. Transferred in the following year to the chair of Surgery in the Transylvania summer school, on the retirement of his uncle from active professional life, he continued to teach with distinguished ability in the position made illustrious by his predecessor, until the close of the school shortly before the outbreak of our Civil War. In the second year of the Kentucky School of Medicine, he was transferred to the chair of Surgical Anatomy and Operative Surgery, and accordingly gave the surgical-clinical instruction in the Marine Hospital of Louisville to the combined classes of the two medical schools of that city during the session of 1851-52. A course which was a decided success for the young professor and surgeon, and which helped to place him at once on the elevated position as a professional man and a gentleman which he maintained to the day of his death and to which few men, of his age especially, ever are fortunate enough to attain.[94]
