海角乐园电视纪录片With regard to the sub-orbital sinus, which in this and all the neighbouring species is of very considerable size, its uses are evidently connected with the function of respiration, and probably also with the sense of smell. It is denoted externally by a longitudinal fissure, placed beneath the inner angle of each of the eyes, and leading into a sac or cavity, which in some cases communicates internally with the nose; and its inner surface is lined by a membrane abundantly supplied with follicles for the secretion of mucus, which is sometimes produced in very large quantities. This latter circumstance has induced some naturalists to regard these openings as mere cuticular appendages. That they really, in some species at least, communicate with the nostrils, is proved by the observations of Mr. White of Selbourne, who states that in consequence of this communication the Fallow-Deer are enabled to take long-continued draughts with their noses deeply immersed in the water, the air in the mean time passing throug

The Bornean Bear is perhaps somewhat shorter in his proportions than the rest of the group, and the great proportional breadth of his head extends also to the neck and body. The claws are very long, strongly arched, and very gradually attenuated to the point, which is transversely truncated and chiefly fitted for digging the earth; but probably also enabling it to climb with great agility. The fur is short and glistening, somewhat rigid, but closely applied to the skin, and smooth to the touch. On the body, head, and extremities, the Bornean Bear has the same pure, saturated,[135] jet-black tint which is observed in the Malayan. The muzzle, including the region of the eyes, has a yellowish brown colour; and the anterior part of the neck is marked by a large broad patch of a more vivid and nearly orange tint, which is of an irregular quadrangular form, and deeply notched above. The difference in the form and colour of this patch constitutes the chief distinction between the present animal and the Malayan speci

It is in the night-time more particularly that the Lion prowls abroad in search of his prey, the conformation of his eyes not only, like those of the cat, allowing him to see with a very moderate degree of light, but even rendering the full glare of day distressing and intolerable to him. It is for this reason that travellers, who are compelled to sleep in the open air in countries infested by these animals, are careful to keep up a blazing fire, which the tenderness of their eyes deters them from approaching, unless when they are extremely hard pressed by the calls of hunger. These, it would appear, sometimes become paramount to every other consideration, and urge the Lion, as they do many more ignoble beasts, into the exhibition of a degree of courage, which,[19] in despite of all that has been said on the subject, is by no means his natural characteristic.
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[46] 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 b
