“The tail is not round, but from the middle to the end is flat, like an eel. Upon the tail and the thighs, there are some round scales of a whitish colour, broad as a French bean; these small scales are also seen upon the breast, the neck, and upon some parts of the head.
“The head, from the extremity of the lips to the beginning of the neck, is two feet four inches, and its circumference about five feet eight inches.
“The ears are two inches and near an half long, more than two inches in breadth, are a little pointed, and furnished on the inside with thick, short, and fine hairs, of the same colour as the others.
“The space between each angle of the eyes is two inches and upwards, and from one eyelid to the other, is one inch and one line.
“The nostrils are two inches four lines long, and little more than one inch broad.
“The mouth, when open, measures about one foot six inches; it is of a square form, and furnished with forty-four teeth of different shapes. All these teeth are so hard, that they strike fire with steel. The enamel of the canine teeth in particular, have this hardness; the interior substance being not so hard. When the hippopotamus keeps his mouth shut there are no teeth to be seen, for the lips, which are extremely large, completely cover them.
“In respect to the figure of this animal, it may be said to be constructed between that of the buffalo and hog, because it participates of both, except the incisive teeth, which have no resemblance to those of either of these animals. The grinders are a little like those of the buffalo or horse, but much larger. The colour of the body is dark and blackish. It is affirmed that the hippopotamus produces but one young at a birth; that he lives on fish, crocodiles, and even the flesh of dead bodies; however, he eats rice, grain, &c. though on considering his teeth, we should conclude that Nature had not made him for grazing, but for the destruction of other animals.”
Zerenghi finishes his description by affirming that all the above measures were taken from the female hippopotamus, whom the male perfectly resembled, excepting that he was a third bigger in all his dimensions. It were to be wished that the figure given by Zerenghi had been as good as his description; but the drawing was not taken while this animal was living, but from the skin of the female. It appears also, that it was from this same skin preserved in salt, that Fabius Columna designed his figure; but the description Columna has given, is not so good as that of Zerenghi’s, and he must be reproached for only quoting the name and not a word about the work of this author, though published three years before his own: he must also be accused of swerving from his description in many essential points, without giving any reason for it; for example, Columna says, that in his time, in 1603, Frederico Zerenghi brought from Egypt to Italy an hippopotamus preserved in salt, while Zerenghi himself says, he brought only the skin. Columna also gives to his hippopotamus thirteen feet in length, to the circumference fourteen, and the legs three feet and a half long; while the measures of Zerenghi makes the length of the body but eleven feet two inches, the circumference ten, and the legs one foot ten inches and a half, &c. We must not, therefore, rely on the description of Columna; nor excuse him upon the supposition that he took it from another subject; for it is evident, from his own words, that he made it from the smallest of Zerenghi’s two hippopotami; since he acknowledges that some months after Zerenghi shewed a second hippopotamus much larger than the first. What makes me so strenuous on this point is, that no one has rendered justice to Zerenghi, who, notwithstanding, is the only person who deserves eulogiums on this subject. On the contrary, every naturalist, for this hundred and sixty years, have attributed to Fabius Columna what they should have given to Zerenghi; and instead of searching for the work of the last they have set down contented with copying and applauding that of Columna’s, who, however deserving of praise in other respects is, upon this, neither original, exact, nor even honest.
The description and figures of the hippopotamus that Prosper Alpinus published more than a hundred years after, are still worse than those of Columna, having been drawn from skins but badly preserved; and M. de Jussieu, who wrote of the hippopotamus in 1724, has only described the skeleton of the head and feet.
By comparing these descriptions, and especially that of Zerenghi, with the information we have drawn from travellers, the hippopotamus appears to be an animal whose body is longer and as thick as that of the rhinoceros; that his legs are much shorter; that his head is not so long, but larger in proportion to his body: that he has no horns, either on the nose like the rhinoceros, or on the head like the ruminating animals. His cry when hurt, according to ancient and modern travellers, resembles the neighing of a horse and the bellowing of the buffalo; his usual voice may be like the neighing of a horse, from which, however, he differs in every other respect. If thus be the fact, we may presume that this resemblance in the voice has been the reason for giving him the name of hippopotamus, which signifies the river horse, as the howling of the lynx, which resembles that of the wolf, occasioned him to be called the lupus cervarius. The cutting teeth of the hippopotamus, and especially the two canine of the lower jaw, are very long, and so hard and strong that they strike fire with a piece of steel. This is probably what, gave rise to the fable of the ancients, that the hippopotamus vomited fire: these canine teeth are so white, so clean, and so hard, that they are preferable to ivory for making artificial teeth. The cutting teeth, especially those of the lower jaw, are very long, cylindrical and furrowed; the canine teeth are also very long, crooked, prismatic, and sharp, like the tusks of a boar: the grinders are square, or rather oblong, nearly like those of a man, and so large that a single one weighs more than three pounds; the largest of the cutting, and the canine teeth are twelve and even sixteen inches in length, and sometimes weigh twelve or thirteen pounds each.
