AB At the Washington session of the American Medical Association in May, 1927, I reported some preliminary observations on the crystalline lens system. I now present some additional data pertaining to the lens system, especially from the point of view of comparative anatomy. It would seem unnecessary to defend the study of any anatomic structure either in regard to its embryologic development in man or in connection with the long and complicated processes illustrated in various lower species of the animal kingdom. The nature of the lens, the purpose for which it was formed, the mechanism of its movements, its growth and its nourishment, the factors leading to its degeneration and the measures that will prolong its usefulness, and, finally, the procedures best adapted to restore vision when lost through lenticular opacities or luxations are all better understood when we can see, although dimly, the mysteries of nature's methods and her
