"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
