all the northern parts of Africa, from the Mediterranean to the Bamboo river, which flows at the foot of Mount Atlas; the climate which the hippopotamus actually inhabits, therefore extends only from Senegal to Ethiopia, and from thence to the Cape of Good Hope. As most authors have called the hippopotamus the _sea-horse_, or _sea-cow_, it has sometimes been confounded with the latter, which is a very different animal, and which only inhabits the northern seas. It appear, then, to be certain, that the hippopotami, which the author of the description of Muscovy says are found upon the borders of the sea of Petzora, are no other than sea-cows, and Aldrovandus merits reproach for adopting this opinion without examination, and asserting that the hippopotamus is found in the northern seas: for he not only does not inhabit the north seas, but it appears that he is rarely found in those of the south. The testimonies of Odoardus, Barbossa, and Edward Wotton, recounted by Aldrovandus, and which seem to prove that the hippopotamus inhabits the Indian seas, appear to be almost as equivocal as that in the description of Muscovy; and I am inclined to believe that the hippopotamus is not to be found, at least at present, but in the greatest rivers of Africa. Kolbe, who says, he has seen many of them at the Cape of Good Hope, affirms, that they equally plunge themselves into the sea and rivers, and which is asserted by other authors. Although Kolbe appears to be more exact than common in his description of the hippopotamus, yet it is doubtful whether he saw it so often as he says, since the figure he has joined to his description is worse than those of Columna, Aldrovandus, and Prosper Alpinus, which are all drawn from stuffed skins. It is easy to discover that the figures and description in Kolbe's works, have neither been made on the spot, nor taken from Nature. His descriptions are written from memory, and most of the figures been copied from those of other naturalists; the figure which he gives of the hippopotamus, in particular, bears a great resemblance to the cheropotamus of Prosper Alpinus.
