Book 8
48
He says also that man is the only animal which has its heart on the left side; and that all other animals have it in the middle of the body. And he says that males have more teeth than females; and he affirms that this has been noticed in the case of the sheep, and of the pig, and of the goat. And he says also that there is no fish which has testicles, and there is no fish which has a breast, and no bird ether; but that the only fish which has no gall is the dolphin. There are, however, some, says he, which have no gall in their liver, but they have it near their bowels; as the sturgeon, the synagris, the lamprey, the sword-fish, and the sea-swallow. But the amia has its gall spread over the whole of its entrails: and the hawk and the kite have theirs spread both over their liver and their entrails; but the ægocephalus has his gall both in his liver and in his stomach: and the pigeon, and the quail, and the swallow have theirs, some in their entrails, and some in their stomach.
