ting addition having been made to the stock of the Menagerie by the acquisition of a couple of Spotted Hy?nas; a brief notice of which we subjoin, as well as their portraits by way of tail-piece, they having arrived during the progress of the present sheet through the press, and consequently too late for insertion in their proper place.

The animals of the part of New Holland from which these birds are derived appear in general to suffer little from their transportation to the climate of England. The Emeus, like the Kanguroos, have become to a certain extent naturalized in the Royal Park at Windsor, where they breed without difficulty and with no extraordinary precautions. Here they have assigned to them a sufficient space of ground to take ample exercise; and this circumstance contributes not a little to the thriving condition in which they are met with. They are perfectly harmless unless when irritated or pursued, in which case they sometimes strike very severe blows with their beaks, which are extremely hard. The pair in the Tower were obtained from this establishment, where they were bred.

y common in the Wolf with the incurved; and this petty distinction, which has little to do with structure, and still less with habits, is hardly deserving of serious attention. More obvious and more essential differences will be found in the cast of his countenance, which derives a peculiar expression from the obliquity of his eyes; in the breadth of his head, suddenly contracting into a slender and pointed muzzle; in the size and power of his teeth, which are comparatively greater than those of any dog of equal stature; in the stiffness and want of pliability of his limbs; in his uniformly straight and pointed ears; and in a black stripe which almost constantly, and in nearly every variety of the species, occupies the front of the fore leg of the adult. His fur, which differs considerably in texture and colour, from the influence of climate and of seasons, is commonly of a grayish yellow, the shades of which are variously intermingled; as he advances in age it becomes lighter, and in high northern latitudes

The engravings have been executed throughout by Messrs. Branston and Wright. Determined on securing the accuracy of the representations, they have in every instance compared the proofs with the animals, and have made corrections where necessary until the resemblance has been rendered perfect. In one case alone has a deviation from the original been indulged in: the tail of the ocelot has been figured of the length usual in the species, instead of the truncated state in which it exists in the specimen; the markings of the animal are, however, as noticed in its article, accurately represented.

The feet of the Camels and of the Llamas are very different in form from those of all the other Ruminants. They are, it is true, deeply divided, like those of the latter, into two apparent toes; but cannot be said, like them, to part the hoof, for they have no real hoof, and the extremities of their protruded toes are armed only with short, thick, and crooked claws. These toes are in the Camels united posteriorly by a horny process, which is wanting in the Llamas. The teeth of both are nearly similar: they consist of six incisors in the lower jaw and two in the upper; of two canines in each; and of six molars in the upper, and five in the lower, on each side. None of the other Ruminants exhibit the least appearance of cutting teeth in the upper jaw. The nostrils of both consist externally of mere fissures in the skin, which may be opened and closed at pleasure, and which are surrounded by a naked muzzle; and their upper lip is divided into two distinct portions, which are very extensible, and capable of much

The Pelican affords an excellent illustration of the fifth and last Order of Birds, the Swimmers; the essential character of which consists in the membranous union of the toes, which renders them what is usually termed web-footed, and enables them to propel themselves upon the surface of the water with greater or less rapidity in proportion to the greater or less comparative extent of the membrane in which their toes are enveloped. They are all consequently inhabitants of marshy situations, of the banks of rivers and lakes, or of the seacoast; and most of them seek their subsistence in their most congenial element, the water, notwithstanding that by far[228] the greater number of them are also endowed with very considerable powers of flight.

The Elephants belong to the Pachydermatous order, in which they constitute a family readily distinguishable from the other enormous beasts which form part of it, the Hippopotamus and the Rhinoceros, by a combination of characters of the most remarkable description. To the immense size and clumsy figure of the two last named animals, which indeed they commonly surpass in both those particulars, they add the following distinctive[165] zoological characters. Their teeth consist of two formidable tusks, which, occupying the place of the incisors of the upper jaw, project forwards in a nearly horizontal direction, generally with a slight curvature upwards; and of one or occasionally two cheek teeth of considerable magnitude on each side of each jaw, formed of vertical layers of bony matter surrounded by enamel, and connected together by a third substance called cortical. These latter are not, as in almost all the other Mammalia, renewed for one only time and at a certain age by the growth of others to supply their

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 except
