+Sterility Is Banished.+ As a rule the women who come to me for treatment prefer to bear male children. In such cases it is essential that they should receive the interstitial glands of the male goat. We have in hospital at the moment, however, a childless married woman of twenty-eight, who wishes devoutly for a female child. We found her sterile of a natural gland and inserted the gland of a female goat. Her transformation has been remarkable, and I am confident her first child will be a girl. You naturally ask about the future, which can only be premised. Women who have received male goat-glands will continue to bear male children, if any; those that receive the female goat glands will continue to bear girl babies. The future carries a promise of much information to be gleaned along this line. I cannot say what would happen if the husband were to receive male goat glands and the wife female goat glands. Their progeny might or might not be mixed. We will try it on any sterile couple that desires, knowing positively that normal children of one or both sexes will result. Where substitution of glands of any character is essential, they should be taken from the goat operated upon immediately before the human implanting, and be inserted at once. Glands should not be taken from the ape or other animal for human use. The goat is immune to tuberculosis, He is a clean animal, full of health and vitality. Apes are very subject to tuberculosis. One can never tell whether an ape is diseaseless or not. It is generally unlawful to substitute our human glands, and, even though they could be readily obtained, they are apt to be infected with some disease. The essential element of foods is the vitamin, a nitrogenous substance of indeterminate nature. Without it we would starve, though eating plenty of proteins, carbo-hydrates, fats, salts and water. Nothing will sustain life if the vitamins are absent from the diet. Goat's milk contains these important substances in greater abundance than any other animal food. +The Goat Reacts Like Human.+ The goat alone among mammals reacts to poisons almost identically as human beings react, and the poison gases of the war had precisely the same effect upon him as upon the soldiers. So 1,500 goats did their bit in the war in an experimental way. These points in his favor, and other similarities to man, are the reasons which led me to select the goat as the best possible material in this work. Goat-glands alone seemed to be harmonious and sympathetic when transplanted into the human body. In other words, the hormones of goat and man agree.
