He graduated from Harvard in the famous class of 1829, for which he afterward wrote many anniversary poems. He went to Paris to study medicine, a science that held his interest through life. For thirty-five years he was professor of anatomy in the Harvard Medical School, where he was the only member of the faculty who could at the end of the day take the class, fagged and wearied, and by his wit, stories, and lively illustrations both instruct and interest the students. His announcement, "small fevers gratefully received," his humor in general, and his poetry especially, did not aid him in securing patients. His biographer says that Holmes learned at his cost as a doctor that the world had made up its mind "that he who writes rhymes must not write prescriptions, and he who makes jests should not escort people to their graves." He later warned his students that if they would succeed in any one calling they must not let the world find out that they were interested in anything else. From his own point of view, he wrote:-- "It's a vastly pleasing prospect, when you're screwing out a laugh, That your very next year's income is diminished by a half, And a little boy trips barefoot that your Pegasus may go, And the baby's milk is watered that your Helicon may flow." He was driven, like Emerson and Lowell, to supplement his modest income by what he called "lecture peddling." Although Holmes did not have the platform presence of these two contemporaries, he had the power of reaching his audiences and of quickly gaining their sympathy, so that he was very popular and could always get engagements. His scientific training made him intolerant of any philosophical or religious creed which seemed to him to be based merely upon superstition or tradition. He was thoroughly alert, open-minded, and liberal upon all such questions. On subjects of politics, war, or the abolition of slavery, he was, on the other hand, strongly conservative. He had the aristocratic dread of change. He was distinctly the courtly gentleman, the gifted talker, and the social, genial, refined companion. [Illustration: HOLMES'S STUDY]
