It is in the swampy forests of South America that the Jaguar commits his destructive ravages, which are spread over nearly the whole of that continent from Paraguay almost to the Isthmus of Darien. It has frequently been said that he is also to be found in Mexico; but this appears to be a mistake, originating probably in Buffon’s having confounded the Jaguar with the Ocelot, describing and figuring the latter under the name of the former, and intermingling with his description many of the peculiar traits of the real Jaguar derived from the relations of travellers. On the other hand he has erroneously figured the latter animal under the name of the Panther; a mistake in which he has been followed by Pennant and others, and with which the writings of zoologists are more or less infected even up to the present day. What the Panther of the ancients actually was, or whether there exists any real difference between it and the Leopard, is a much disputed question, into which we have neither space nor inclination to enter: certain it is that it could not possibly have been the present animal, which has never been found out of the limits of America; and that Buffon himself had no idea, while he was figuring the latter, that the specimen before him was not a native of Africa or the East. The name of Jaguar is corruptedly derived from the Brazilian appellation of the animal, to which the Portuguese have given the name of Onça; another blunder, for the Ounce of the Old World is now universally allowed to be identical with the Leopard, and with the latter we have already shown that it is impossible that the American species can be conjoined.
Like the Cats already described, to whom, however, he is much inferior in the suppleness and elasticity of his motions, the Jaguar makes his solitary haunt in the recesses of the forest, especially in the neighbourhood of large rivers, which he swims with the greatest dexterity. Of the extent of this faculty, as well as of his extraordinary strength, some judgment may be formed from a circumstance related by D’Azara, which fell partly under that traveller’s personal observation; namely, that a Jaguar, after having attacked and destroyed a horse, carried the body of his victim for about sixty paces to the bank of a broad and deep river, over which he swam with his prey, and then dragged it into the adjoining wood. According to M. Sonnini he is as expert at climbing as at swimming. “I have seen,” he says, “in the forests of Guiana, the prints left by the claws of the Jaguar on the smooth bark of a tree from forty to fifty feet in height, measuring about a foot and a half in circumference, and clothed with branches near its summit alone. It was easy to follow with the eye the efforts which the animal had made to reach the branches: although his talons had been thrust deeply into the body of the tree, he had met with several slips, but he had always recovered his ground, and, attracted no doubt by some favourite object of prey, had at length succeeded in gaining the very top.”
