    in a stimulating manner on the entire internal glands and on the central nervous system by way of the circulation. But it should be remembered that the pituitary and adrenal glands are also connected with the sex func¬ tion ; and there is a relationship between the thyroid and the female reproductive gland. Altogether, it is now known that the endo¬ crine glands never function separately. Each influences the other in a communicating chain. Let one be disturbed, and all the others will feel the impact of the disturbance and vibrate with it. Since the female sex glands—the ovaries— are too deeply seated, the operation cannot be performed on women, and quite a different treatment—internal electrical heating, by diathermy—is adopted. Steinach certainly succeeded with animals; rats and guinea-pigs. He was the first to produce a transformation of sex characters by removing the ovaries of a young female guinea- pig and ingrafting the testicle of a young male; and replacing an ovary for the testicle removed from a male guinea-pig. The effect that was produced was entirely by the interstitial part of the gland, and the production of the germ or sperm cells is in no way connected with it.
