The pure whiteness then of the covering of the animal in question, and of all those which exhibit a similar variation from their natural tinge, is attributable solely to the absence of this secretion from whatever[195] cause. It is always accompanied, as in the present instance, by a redness of the eyes, arising from the blood-vessels of the iris being exposed to view in consequence of the want of the usual coating formed by this secretion, by which they are naturally protected from the too great influence of the light. In the human race the individuals who are thus afflicted, characterized by the dull whiteness of their skins, the deep redness of their eyes, and their colourless, or, as it is generally termed, flaxen, hair, are called Albinos. They are generally timid in disposition, languid in character, and weak both in mind and body. The same original conformation, for it is always born with the individual and never acquired in after life, although sometimes prolong

The species of the group, of which the Llama forms[183] the type, have been involved by the imperfect descriptions of naturalists in almost inextricable confusion. No less than five have been admitted; but the variations of colour and of size, and the degree of length and fineness of the wool, differences rather commercial than natural, afford almost the only positive distinctions that have yet been laid down between them; and when we consider that some of them have been for ages in a state of domestication, it will readily be allowed that such characters as these are, to say the least, trivial and uncertain. Our animals, which are nearly four feet in height at the shoulder, and somewhat more than five feet to the top of the head, have the neck, the back, the sides, and the tail, which is rather short, covered with a beautiful coat of long, bright brown, woolly hair. The long and pointed ears, and the small and attenuated head, on which the hair is short, close, and even, are of a grayish mouse-colour; the ouFelis Jubata. Schreb.

Ichneumon Griseus. Geoff.Of the characters of most of the institutions which we have noticed the Tower Menagerie has at various times partaken in a greater or less degree. Originally intended merely for the safe-keeping of those ferocious beasts, which were until within the last century considered as appertaining exclusively to the royal prerogative, it has occasionally been converted into a theatre for their contests, and has terminated by adapting itself to the present condition of society as a source of rational amusement and a school of zoological science.

It has been generally remarked, that lions in captivity have certain constant and stated times for roaring: this observation is not, however, strictly true with regard to those now in the Tower. It may nevertheless be observed that in the summer time, especially when the atmospheric temperature is considerable, they uniformly commence roaring about dawn, one of them taking the lead, and the others joining in the concert in succession; and Mr. Cops has frequently had occasion to remark that whenever any one of them fails in accompanying the rest in their by no means harmonious performance, the cessation from the customary roar is an infallible symptom of actual or approaching illness. At no other time is there that regularity in their roaring which has been so frequently stated; although the chorus which has just been described is sometimes repeated after feeding, and also when they have been left alone for any length of time; hence it occurs particularly on Sundays, a day on which they have no company exceptn, it is rarely observable in the living animal. On these toes they constantly support themselves in walking, the soles of their feet, or rather that part of the legs which corresponds to the soles of plantigrade animals, never being applied to the surface of the ground on which they tread. Their claws are blunt, strong, but little curved, and not at all retractile; and their use is evidently limited to turning up the earth. Their muzzle is more or less elongated to afford space for the ample series of lateral teeth; and the strength of their jaws, as well as the extent of opening between them, is by this means much diminished. In most of these particulars they exhibit a striking contrast with the more perfect of the carnivorous races, and afford grounds for expecting an equally manifest falling off from their ferocious and sanguinary propensities. The dogs are in fact by no means equally carnivorous with the cats; and their teeth, especially the grinders, are fitted as well for the demolition of vegetable as

at liberty, the love of freedom prevails over every other consideration, and they become as wild as if they had never been reclaimed. In eating, they commonly support themselves on their hind legs, and carry their food to the mouth between their fore paws, having first plunged it in water, if the liquid element, of which they are remarkably fond, is within reach. This singular peculiarity, the object of which is not very obvious, but from which the animal derives his specific name, does not, however, appear to be constant and uniform, being frequently entirely neglected. The same may be said of their fondness for shell-fish and mollusca, for which they are generally stated to have a great partiality; some of them, like the handsome pair now living in the Menagerie, displaying the greatest address and dexterity in opening the shell of an oyster, and extracting its contents, while others absolutely refuse to touch it.THE ASIATIC ELEPHANT.
