But the imagination and critical faculties which had given value to his investigations were equally fertile in the more general aspects of his interests. Sought as a member of the most important scientific bodies of our country, he was capable of impersonal judgments and retained, as he would have indefinitely, that combination of the young heart and the old head in which the passage of time makes little difference and which, together, are the essentials of true understanding. Of all his valuable contributions to the development of modern medicine, these short papers are the ones which deal most directly with the problems forced upon medicine by its own rapid development and by the increased opportunities and responsibilities which involved it with educational, social and economic changes. They deal with questions many of which are still unsolved, and their publication will serve to continue the influence of a voice that American medicine could ill afford to lose--one of clear-headedness, unsentimental idealism and the great wisdom of affectionate optimism.
