More circumspect, or rather more cowardly, than any of the larger species of his cautious tribe, he is, notwithstanding his much greater magnitude, scarcely more dangerous than the common wild cat, preying only upon the smaller species of animals, seldom venturing to attack any living creature of greater size or courage than a sheep, and flying from the face of man with more than usual terror. But this cowardice is also, in a state of nature, connected with a degree of ferocity, fully equal to that which is developed in the most savage and blood-thirsty of his fellow cats. Unlike the Jaguar, which generally contents itself with a single victim, the Puma, if he should happen to find himself undisturbed in the midst of a flock of sheep, deserted by their guardians and left entirely at his mercy, is said never to spare, but to destroy every individual that he can reach, for the purpose of sucking its blood. He differs also from the Jaguar in his habit of frequenting the open plain rather than the forest and the李时珍蜜蜂成熟1996正版百度Antilope Cervicapra. Pall.

第2章 两虎相争

were found a beautiful pair of cubs, male and female, supposed to be then not more than three days old. These the General brought away with him, and succeeded by the assistance of a goat, who was prevailed upon to act in the capacity of foster-mother to the royal pair, in rearing them until they attained sufficient age and strength to enable them to bear the voyage to England. On their arrival in this country, in September, 1823, he presented them to his Majesty, who commanded them to be placed in the Tower. The male of this pair is the subject of the present, the female that of the succeeding article.

miserable remnant of its inhabitants at length find it absolutely necessary to quit the ground, and to seek a precarious safety in flight.

Closely allied to the Lion, whom he resembles in size, in power, in external form, in internal structure, in zoological characters, in his prowling habits, and in his sanguinary propensities, the Tiger is at once distinguished from that king of beasts, and from every other of their common genus, by the peculiar marking of his coat. On a ground which exhibits in different individuals various shades of yellow, he is elegantly striped by a series of transverse black bands or bars, which occupy the sides of his head, neck, and body, and are continued upon his tail in the form of rings, the last of the series uniformly occupying the extremity of that[26] organ, and giving to it a black tip of greater or less extent. The under parts of his body and the inner sides of his legs are almost entirely white; he has no mane; and his whole frame, though less elevated than that of the Lion, is of a slenderer and more graceful make. His head is also shorter and more rounded.

eral herd, indulge perhaps more frequently in these excesses than the community, which generally avoids as much as possible the habitations of man. It has commonly been imagined that these stray Elephants were the younger and weaker males, who had been driven from the herd by their more powerful fellows; but the fact that they are usually adults of the largest size completely negatives this supposition, and proves that it is of their own free will that they wander thus alone. They attain their full growth between the ages of eighteen and twenty-four, and well authenticated instances have occurred in which they have reached the age of a hundred and thirty years. Indeed there is reason to believe that their life may be sometimes prolonged to two centuries.

From the strongly marked group, to the illustration of various species of which the foregoing pages have been dedicated, we pass by a natural and easy transition to an animal, which, although closely resembling them in its zoological characters, and in the cowardly ferocity of its disposition, bears nevertheless a stronger affinity to the dogs, with which it was associated by Linn?us. From each of these groups it is, however, readily distinguished by several obvious and essential characters, of sufficient importance to sanction its separation as a genus, now universally adopted among naturalists.

It is on this account that we feel it incumbent upon us, notwithstanding all that has been written on the subject, to dwell with some little detail on the natural history of this singular animal; but we shall nevertheless endeavour to compress our observations within the smallest possible compass. We shall commence as usual with his zoological characters, and shall then take a glance at his habits, such as they appear in a pure state of nature, unfettered by any laws but those of necessity, and uncontrolled except by the inevitable influence of the circumstances in which he is placed. And lastly we shall view him when under the control of man, and reduced to that half-domesticated condition to which even his stubborn nature is bowed by the application of those means which man alone can employ, and by which he maintains his ascendancy as undisputed lord of the creation over the mightiest even more effectually than over the meanest of its works.

The beautiful bird, the portrait of which is prefixed to the present article, is one of the rarest of its tribe, and has until very lately been confounded by ornithologists with the Hyacinthine Macaw, a fine but much less splendid species. It is figured by M. Spix in his Brazilian Birds under the name which we have adopted; but is there given without either characters or description. Its claim to generic distinction would seem to depend on the excessive length and powerful curvature of its claws and upper mandible, and on the slight developement of the toothlike process of the latter. Its colour is throughout of a deep and brilliant blue; the beak, legs, and claws, are black; and the cere and a naked circle round each of the eyes are of a bright yellow. Our specimen measures two feet four inches from the top of the head to the extremity of the tail, and the expansion of his wings is four feet. The length of the upper mandible is five inches, and that of the lower, two.

in general sufficient to teach him that his purpose is as effectually answered by one fatal bound as by the most extensive devastation; for neither he, nor any of the more powerful of his tribe, return to their prey after the first meal, but leave its mangled relics for the ignoble beasts which follow in their train.
