Th. Serge Voronoff, head of the phychological laboratorie of the Col lege De France, who unfolded recently before the French Congress of Surgery the results of an amazing series of exprriments designed to restore youth ful power to the aged. The sensational results of Dr. Voronoff's experiments have startled the medical and scien tific world. Dr. Voronoff contends that during his course of experiments on the subject, which extended over a period of three years, he restored youthful energy to a man eighty years old, giving him the vitility and ro bustness of a young man. The experi ments involve the grafting of an in terstitial gland of a young male mon key on to an old man in whom the gland has become atrophied. Old ani mals upon which the experiments were first tried apparently were re stored to youth. Der Serge Voroxoff
