The retirement of Dr. Oliver Wendell Holmes from the professorship in the Harvard Medical School, which he has held for thirty-five years, is an interesting event in the career of a distinguished and honored man. During the generation which has placed him among the foremost of our men of letters, Dr. Holmes has been devoted also to scientific study, and the brilliancy of his wit and the tender glow of his poetic genius have but enhanced the value of his professional teaching. The Professor, the Autocrat and the Poet have been interchangeable, and his latest published lecture to his classes is as notable for various and accurate and unusual learning as it is for crisp and charming literary skill. It is no less full of delight and instruction for the general reader than of historic value to the professional student. It is pleasant to know that Dr. Holmes resigns only that he may devote himself more exclusively to literary occupations. The professor who has taught the Medical School withdraws in favor of the professor who has charmed all the world. - [Harpers' Weekly.
