《Natural History（8 自然史第8卷）》：

　　HAVE been informed by Mr. Bruce that in his travels through Africa hefrequently saw hippopotami in Lake Tzana, in Upper Abyssinia, near the sources of the Nile; that in this lake these animals are more numerous than in any other part of the world, and that he saw some which were at least twenty feet in length.

　　Dr. Klockner, in his translation of the present work, printed at Amsterdam, says, he is surprised that M. de Buffon should have taken no notice of a pas- sage in Diodorus Siculus, respecting the hippopotamus, in which that author observes, "that among the various animals produced by the Nile, the crocodile and hippopotamus deserve the most particular attention, the latter is five cubits long; he has cloven feet like ruminating animals, and in each of his jaws he has three large tusks, somewhat like those of a wild boar; while the prodigious size of his body resembles that of an elephant. His skin is exceedingly hard and strong, possibly more so than that of any other animal. He is amphibious, and remains as perfectly at ease under water as upon land; he, however, comes on shore in the night to seek pasture, and if the species were numerous, they would prove very destructive to the cultivated lands of Egypt. To hunt this animal a number of men assemble, and going in several boats attack him; when once fastened to a rope, they leave him till he is exhausted with plunging and the loss of blood: his flesh is hard, and not good for digestion." Dr. Klockner has also given an account of the manner in which the skin was prepared of the one sent from the Cape of Good Hope, and is now in the Prince of Orange's cabinet, the dimensions of which corresponded very nearly with those of Zerenghi's. He likewise adds, that he was informed by the nephew of Charles Marias, a peasant of French extraction, who shot this hippopotamus, and from whom he had the relation, that the animal had wandered a considerable way upon land, almost to a place called the Mountains of Snow; this Marias asserted that the hippopotamus runs very swift upon land, and for which reason these peasants, though good hunters, never attempted to attack him but when he was in the water; that it was the practice to watch for him about sun-set, at which time he raises his head above water, and perceiving any object of prey, darts upon it with surprising quickness; during his thus floating on the surface, he keeps his ears in perpetual motion, constantly listening if any noise is near, and while in this position the hunters endeavour to shoot him in the head; when wounded he plunges under the water and traverses about as long as life remains, and then floats to the top; some of the party swim to him, and being fastened by ropes he is dragged on shore by oxen, where he is immediately dissected. A full grown hippopotamus generally yields about 2000 lbs. weight of fat, which is salted and sent to the Cape, where it is much esteemed and sells very dear. By compression a mild oil is drawn from it, which in Africa is considered as a certain remedy for diseases in the breast.

　　In our preceding description of this animal we remarked, that it was probable the hippopotamus was so called from his voice having a resemblance to the neighing of a horse, but from many authentic accounts, we understand that it comes nearer to the cry of the elephant, or the indistinct stammerings of persons who are deaf. When asleep he also makes a snorting noise by which his retreat is discovered at a distance; and of this he seems aware, as he generally lies among reeds upon marshy grounds, and where it is very difficult to come near him.

　　I cannot consider the remark of Marias, relative to the speed of this animal, as correct; since so far from its being corroborated, all others affirm that the hunters rather attack him on land than in the water, which is a proof they are not afraid of his swiftness; nay, some affirm that it is customary to impede his return by trees and ditches, from his constantly endeavouring to regain the water, where he has no enemy to apprehend, as both crocodiles and sharks carefully avoid him.
