糖心网剧糖点爆棚The very peculiar structure from which the Marsupial animals derive their name has been regarded by almost every naturalist who has written on the subject as so essential a deviation from the common type, that, setting aside all considerations of form or habits, and regardless even of those technical characters on which so much reliance is usually placed, they have for the most part agreed in uniting under the same family designation every animal in which it occurred. This peculiarity consists in a folding or doubling of the skin and its appendages beneath the lower part of the belly in the females, in such a manner as to form an open pouch or[156] bag, in which the young are contained from a very early period, in which the process of suckling takes place, and in which, even for some time after they have acquired sufficient size and strength to leave it, the little ones continue to take refuge.
Anodorhynchus Maximiliani. Spix.糖心网剧糖点爆棚But the presence of this one anomalous characteristic is accompanied by so many striking discrepancies in other parts, that, limited as this tribe is in number, most of the principal forms of Mammalia find analogous representations among its groups. Thus the Opossums exhibit characters in some measure intermediate between the Quadrumana and the Carnivora, to which latter the Dasyuri, another Marsupial group, closely resembling the Civets in form and habits, approach very nearly; while the herbivorous races of the tribe might occupy a station between the Rodent and Ruminant Orders, with each of which they exhibit various degrees of relationship. This want of uniformity in the essential parts of their organization necessarily gives rise to much difficulty in determining their position in the system. The mode of classification now most generally followed is perhaps, under all the circumstances, the best that could at the present moment be adopted; although it must be owned that the purely herbivorous species arr
e tubercle in others, in a third group is short and tapering, in a fourth of moderate length and cylindrical, in a fifth extremely long but uniformly covered with hair; in others, again, of equal length, divested of hair beneath and near the tip, and capable of being twisted round the branch of a tree or any other similar substance in such a manner as to support the whole weight of the animal, even without the assistance of his hands.
THE AFRICAN PORCUPINE.
The Jaguar is generally said to be quite untameable, and to maintain his savage ferocity even in a state of captivity, showing no symptoms of attachment to those[48] who have the care of him. This assertion is amply contradicted by the fact that an individual confined in the Paris Menagerie, was exceedingly mild in his temper, and particularly fond of licking the hands of those with whom he was familiar; as was also remarkably the case with the specimen lately in the Tower, whose portrait ornaments the present article. This animal was obtained by Lord Exmouth while on the American station, and accompanied the expedition to Algiers at the memorable bombardment of that nest of pirates. On his return to England, his Lordship gave it to the Marchioness of Londonderry, who soon afterwards presented it to his Majesty, by whose order it was placed in the Tower; where it continued until a short time since, when it unfortunately died. Mr. Cops is, however, in expectation of being soon enabled to replace it. It was exh
ed beyond its limits in the shape of an hereditary legacy, is common to many animals. Perhaps the most familiar instances among these are the white mice, the white rabbits, and the white pigeons, which are known to every one. But it has also been occasionally seen in many other species, as monkeys, squirrels, moles, pigs, and even cows and horses, and, to come a little closer to our present subject, in goats and deer. Not even that massive and stupendous beast the Elephant is exempted from its influence. It can hardly be necessary to recall to the reader the title on which the ruler of millions of not uncivilized Asiatics, the Burmese monarch, prides himself more than on any other, inasmuch as it is the emblem of power and prosperity, that of Lord of the White Elephant; a title, which, while it demonstrates the fact of the existence of this deviation in the Elephant as well as in other animals, proves also[196] the extreme rarity of its occurrence. It has moreover been noticed in many species of birds.
The present species of Antelope is spread over the whole of the Peninsula of Hindoostan and a part of Persia; but it is questionable whether it has been found in Africa, as is commonly asserted. They are said to bound with apparent ease over a distance of from twenty-five to thirty feet, and mounting to the height of ten or twelve. It is consequently useless to attempt to chase them in the common mode with hounds; and their pursuit is restricted to the higher nobility, who employ for the purpose either hawks, who pounce upon their quarry and detain it until the dogs can come up, or Chetahs, who attack them by surprise in the manner before described.
To commence then with the Eagles, which form a prominent group of the Rapacious Order, and are universally regarded as the most majestic, as well as the most powerful, of birds. In common with the whole[200] Order, they are remarkable for the strong incurvation of their bill and talons, the latter of which are four in number on each of the feet, and are moved by means of a thick and strong muscular apparatus, which gives to the grasp of the larger species that extreme tenacity by which they are distinguished, enabling them to seize and carry off fish and birds, and even quadrupeds of moderate size. This innate propensity to rapine, derived from their peculiar conformation which renders them essentially flesh-eaters, indicates at once the analogical relationship borne by the Rapacious Birds to the Carnivorous Quadrupeds; and the high degree to which it is carried by the Eagles, their vast powers of flight, their towering majesty, their irresistible might, their uniform preference of living victims and rejectio

The Great Sea-Eagle is a native of the Northern Hemisphere, in the colder regions of which he appears to be most at home. He builds his nest in similar situations with the last, but prefers the neighbourhood of the sea, or of lakes and rivers, over which he is frequently to be seen, especially in the morning and towards nightfall, hovering in quest of prey, and pouncing down upon the fish which rise to the surface, or even diving after those which are visible beneath. These form his principal sustenance; but he seldom suffers flesh or fowl to escape him if they chance to fall in his way. His flight is less rapid and less lofty than that of the Golden Eagle; and he neither perceives his prey at such a distance, nor pursues it with such pertinacity.
