was not pleased with musick, and had no idea of singing: finally he was insensible to all enjoyment. He did not however complain of his situation. His intelligence was very slight, his conversation was obscure and incorrect, and he was so incapable of being instructed that although he had lived in the barracks a year he had none of the moral habits of the soldier. (_Journal de med. chir. et phar._ vol. xxv. p. 75.) Such is the eunuch. The operator in mutilating him mutilated his heart, his senses, his mind. The development of the moral and intellectual faculties then like that of the body is connected with the existence of the genital organs. Deprive a child of a limb of his four limbs, that is of the half at least of his frame, and he will continue to be developed, the same as if no part had been taken from him. But take away the testicles, and all his tissues, all his faculties will bear indelible marks of this mutilation. These organs alone then have much more power than the four extremities. It is with these, with this power, that the onanist trifles from childhood, without hesitation and without moderation. Is it necessary now to follow this train of reasoning to show that his course of conduct is dangerous? It is also to the influence exercised by the genital organs on other parts that the sexes owe their peculiar differences. Their organization, influenced by a different genital apparatus, presents a different mode of existence, action and sensation. Thus the sexual characters are slightly marked at birth, become distinct as the genital organs develope themselves, suddenly enlarge at the period of puberty, exist in the greatest degree when these parts have come to their perfect state, and lose their energy in old age. The destruction of the testicles in the male and of the ovaries in the female prevents the regular development, or even alters the special distinctions of sex. We have already seen that this destruction renders man effeminate: we will add that it renders the female more masculine, and gives her characters, which in the natural order of things belong exclusively to the male. This conclusion is drawn from facts which seem authentic, and it is strengthened too by the fact that when the activity of the genitals is destroyed by age, the voice becomes rough, resembling that of the male, the upper lip and chin are covered with hairs, the moral character acquires more firmness, the taste and habits are much modified and approximate those of the male. A similar thing occurs in animals according to Dumeril. (_Dict. des sc. med., art. continence_, p. 118.)
