An eminent historian has remarked that no science, no department of knowledge, can be thoroughly understood except in the light of its historic genesis and growth.1 Historical study thus tends not only to be an aid to refinement, breadth of view and sympathy, but also to be helpful in the handling of great questions in any of the sciences relating to man. It is a splendid discipline for reasoning of the practical kind most needed in the affairs of life. This belief may be offered as the reason for reverting to some of the little known facts regarding certain features of the continually increasing public health movement.
