Abstract
FEW human beings will view the approach of old age with philosophic calm, so that any method by which the period of maturity may be prolonged and the onset of senility delayed will always arouse widespread interest and discussion. Within the last few years a considerable amount of attention has been directed to the subject of rejuvenation, following certain somewhat sensational operations on human beings and the higher apes. Although there is no doubt that the internal secretions of the genital glands exert a pronounced effect upon the rest of the body, yet it is by no means certain that old age can be attributed solely to their degeneration: in fact, the cells of the body as a whole suffer decay, so that it is probable that an operation affecting only one of the organs of the body, only one, moreover, of the number which influence the activities of the other cells throughout life, would have no more than a temporary effect at best.
