Between the crocodile, too, and the hippopotamus there is a certain affinity, frequenting as they do the same river, and being both of them of an amphibious nature. The hippopo- tamus was the first inventor of the practice of letting blood, a fact to which we have[1] made allusion on a previous occasion: it is found, too, in the greatest numbers in the parts above the prefecture of Saïs.

The hide, reduced to ashes and applied with water, is curative of inflamed tumours, and the fat, as well as the dung, used as a fumigation, is employed for the cure of cold agues. With the teeth of the left side of the jaw, the gums are scarified for the cure of tooth-ache. The skin of the left side of the forehead, attached to the groin, acts as an antaphrodisiac; and an application of the ashes of the same part will cause the hair to grow when lost through alopecy. The testes are taken in water, in doses of one drachma, for the cure of injuries inflicted by serpents. The blood is made use of by painters.
