The amputation of the testicles is not very hazardous; it may be performed at any age, yet that of infancy is esteemed the most favourable. The amputation of the whole external parts of generation, however, is more often mortal than otherwise, especially if performed after the age of fifteen; and even at the most favourable age, which is from, seven to ten, it is still attended with danger. The difficulty of preserving them renders the eunuchs of this species by far the most valuable. Tavernier says, that in Turkey and Persia they cost five of six times more than any others. Chardin observes, that the entire amputation is always accompanied with the most agonizing pain; that it is performed with tolerable safety on children, but with great danger after the age of fifteen; that more than a fourth fall victims to it; and that it takes at least six weeks to heal the wound. Pietro della Valle, on the other hand, asserts that those who undergo this operation in Persia, as a punishment for rapes, or other crimes of that nature, recover from it with ease, even when they are advanced in years, and that they apply to the wound nothing but a few ashes. Whether those who suffered the same punishment formerly in Egypt, as related by Diodorus Siculus, found the consequences of it equally mild, we know not; but, according to Thevenot, numbers of the children of negroes perish, whom the Turks force to undergo this operation, although performed at the early age of between eight to ten. Besides negro eunuchs, there are others in Turkey, Persia, &c. who chiefly come from the kingdom of Golconda, the Peninsula on this side the Ganges, the kingdoms of Assan, Pegu, and Malabar, where their complexion is grey, and from the Gulph of Bengal, where it is of an olive colour. There are also white eunuchs from Georgia and Circassia, tho' not in great numbers. Tavernier says, that during his residence in Golconda, in 1657, there were not less than 22,000 eunuchs made. The black ones come from Africa, and chiefly from Ethiopia. Those are the most prized whose appearance is the most ugly and horrible; a flat nose, a countenance ghastly, thick large lips and protuberant, and black straggling teeth are the esteemed qualities. These people have commonly very fine teeth; but such would be a very great defect in a black eunuch, who must be a hideous monster. Eunuchs who have been deprived of only their testicles, still feel an irritation in the parts that are left, and have the external mark of desire even more frequently than other men. Those parts, however, remain, as to size, nearly in the same state as before the operation; and if this is performed at the age of seven years, an eunuch of twenty is, in this respect, as a child of seven. If it is not, on the contrary, performed till the time of puberty, or a little after, the size is nearly the same as that in other men.
