differences not being established from the beginning. Thus the young lion is spotted, during his first year, with dark spots on its lighter ground, and transitorily shows the livery that is most common in the genus. It is singular that man has, in a semi-barbarous state, recognized the same principle as that which constitutes these differences, and applied it to the same purpose. It is well-known that the _setts_, or patterns of several of the highland tartans were originally composed with special reference to concealment among the heather. And with the Highlanders, perhaps, the hint was taken from the ptarmigans and hares of their own native mountains, which change their colors with the season, donning a snow white vest when the ground on which they tread bears the garb of winter, and resuming their garments of grayish brown when the summer's sun has restored to the rocks their natural tints. There are three species sufficiently resembling each other in size and general appearance, to be confounded by persons unacquainted with their characteristics, namely, the leopard, the panther, and the jaguar. The precise distinction between the first two, is still an open question, although the best authorities agree in considering, that they are distinct animals; still confusion exists. An eminent dealer in furs informed us, that in the trade, panther skins were looked upon as being larger than leopards', and the spots more irregular, but the specimens produced were clearly jaguar skins, which made the matter more complicated. The panther, _Felis pardus_, is believed to be an inhabitant of a great portion of Africa, the warmer parts of Asia, and the islands of the Indian Archipelago; while the leopard, _Felis leopardus_, is thought to be confined to Africa. The jaguar, _Felis onca_ is the scourge of South America, from Paraguay almost to the isthmus of Darien, and is altogether a larger and more powerful animal than either of the others. Though presenting much resemblance, there are points of distinction by which the individual may be at once recognized. The jaguar is larger, sturdier, and altogether more thickset than the leopard, whose limbs are the beau ideal of symmetry and grace. The leopard is marked with numerous spots, arranged in small irregular circles on the sides; the ridge of the back, the head, neck, and limbs, being simply spotted, without order. The jaguar is also marked with black spots, but the circles formed by them are much larger, and in almost all, a central spot exists, the whole bearing a rude resemblance to a rose; along the back, the spots are so narrow and elongated, as to resemble stripes. The tail of the jaguar is also considerably shorter than that of the leopard, which is nearly as long as the whole body.
