Note 1726 — BOOK VIII. THE NATURE OF THE TERRESTRIAL ANIMALS.

We have a discussion by Cuvier, respecting the existence of the unicorn, or of any animal similar to that here described, with a single horn. He remarks, that the only single-horned quadruped of which we have any certain knowledge, is the rhinoceros, and that the only horns which have been discovered, and which can have been single horns, belong to it. There are five animals mentioned by the ancients, as having single horns, the Indian ass, the single-horned horse, the single-horned ox, the monoceros, described in the text, and the oryx of Africa, which Pliny speaks of in c. 79 of this Book, and in B. xi. c. 106. There are many curious accounts given by travellers of acknowledged veracity, respecting animals seen in the more remote parts of Asia and Africa, answering to the description of the unicorn, and there are representations of the same in ancient sculptures; but they do not amount to that kind of evidence which can at all supply the place of direct proof.—B.
