In sheep and cattle the testes hang down to the legs, while in the boar they are knit up close to the body. In the dolphin they are very long, and are concealed in the lower part of the belly. In the elephant, also, they are quite concealed. In oviparous animals they adhere to the interior of the loins: these animals are the most speedy in the venereal congress. Fishes and serpents have no testes, but in place of them they have two veins, which run from the renal region to the genitals. The bird known as the "buteo,"[1] has three testes. Man is the only creature in which the testes are ever broken, either accidentally or by some natural malady; those who are thus afflicted form a third class of half men, in addition to hermaphrodites and eunuchs. In all species of animals the male is more courageous than the female, with the exception of the panther and the bear.
