No two-horned Rhinoceros seems to have been brought alive to Europe in modern times. Indeed, up to a comparatively late period, their form was known only by the horns which were preserved in museums; nor did voyagers give any sufficient details to impart any clear idea of the form of the animal. The rude figure given by Aldrovandus, in 1639, leaves no doubt that, wretched as it is, it must have been taken from a two-horned Rhinoceros. Dr. Parsons endeavoured to show that the one-horned Rhinoceros always belonged to Asia, and the two-horned Rhinoceros to Africa; but there are two-horned Rhinoceroses in Asia, as well as in Africa. Flacourt saw one in the Bay of Soldaque, near the Cape of Good Hope, at a distance. Kolbe and others always considered the Rhinoceros of the Cape as two-horned; but Colonel Gordon seems to be the first who entirely detailed the species with any exactness. Sparrman described the Cape Rhinoceros, though his figure of the animal is stiff and ill-drawn. At this period it was well known that the Cape species was not only distinguished by having two horns from the Indian Rhinoceros then known, but also by an absence of the folds of the skin so remarkable in the latter. We should here notice the carelessness, to call it by the mildest name, of Bruce, who gave to the world a representation of a two-horned Rhinoceros from Abyssinia, with a strongly folded skin. The truth appears to be that the body of the animal figured by Bruce was copied from that of the one-horned Rhinoceros given by Buffon, to which Bruce added a second horn. Salt proved that the Abyssinian Rhinoceros is two-horned, and that it resembles that of the Cape. [Illustration: THE TWO-HORNED AFRICAN RHINOCEROS.] Sparmann exposes the errors and poetic fancies of Buffon respecting the impenetrable nature of the skin. He ordered one of his Hottentots to make a trial of this with his hassagai on a Rhinoceros which had been shot. Though this weapon was far from being in good order, and had no other sharpness than that which it had received from the forge, the Hottentot, at the distance of five or six paces, not only pierced with it the thick hide of the animal, but buried it half a foot deep in its body. Mr. Tegetmeier has sufficiently described in the "Field" journal the African Rhinoceros just received at the Zoological Society's menagerie in the Regent's-park, and which has been sketched by Mr. T. W. Wood expressly for the present volume. It was captured about a year ago in Upper Nubia by the native hunters in the employment of Mr. Casanova, at Kassala; and was sent, by way of Alexandria and Trieste, to Mr. Karl Hagenbeck, of Hamburg, a dealer in wild beasts, who sold it to the Zoological Society.
