Castration of growing male rats and guinea pigs effects a gradual slowing d o w n of the increase in weight. In the rat, all skeletal muscles and the skin participate in this change in proportion (200), w h e r e a s , in the guinea pig, some muscles are affected m o r e strongly by this involution than others (8). 2. T h e involution of muscles after castration can be reversed by the administration of androgen (8,203); h o w e v e r , only very massive dosages of androgen are able to effect a gain in weight going beyond the normal (202).
