and is carefully stored up until a favourable opportunity occurs, when they seldom fail to remember an insult or an injury, even at very distant periods of time.

Haliaetos ossifragus. Sav.

The New Holland Emeu, as well as the Ostrich and the Cassowary, to both of which it is nearly related, is now generally regarded as belonging to the Rasorial Order, the Gallina? of Linn?us, the feet of which are formed for running and for scratching up the earth in search of the seeds which constitute their usual subsistence. Some of the birds, however, which are referred to it, and particularly those now under consideration, feed upon fruits and roots. The whole of the Order are distinguished by a certain degree of convexity on the upper surface of the bill, the base of which is enveloped by a membrane, in which are situated the nostrils covered by a cartilaginous[222] scale; by the muscular plumpness of their bodies, and especially of their legs; by the shortness of their wings, and the diminution of strength in their pectoral muscles; and by the thickness and strength of their anterior toes, generally three in number, united at the base alone by a connecting membrane, and roughened beneath. These character

ttle, to search in the pockets of his keepers for apples or oranges, these and many other tricks of a similar kind, for which he is famous, are evidently nothing more than mechanical actions, to the performance of which he is stimulated, like other beasts, at first by the promise of reward or the fear of chastisement, and afterwards by the mere force of habit. In like manner the dexterity with which he learns to load and unload himself, or to place a man or child upon his back by means of his trunk, without offering them the slightest injury; and on the other hand the precision with which he is made to execute the will of the Asiatic despot on the unhappy victims of his displeasure, by seizing them and casting them beneath his feet, to be there dispatched, according to the tenor of the orders which he receives, either with a single crush, or with all the horrors of a lingering death; these also are actions of no higher order than many other animals are[176] equally capable of in a moral point of view, althoug

The variety figured over leaf is in one of the many intermediate stages between unreclaimed barbarism and complete domestication. It is an awkward looking creature, high on the legs, narrow in the loins, and covered with a rough and shaggy coat. The back and sides are nearly black; the shoulders reddish brown; and the posterior part of the body, the haunches, the hind legs, and the tail, white; as are also the ears, which are rather large, the nose, and a spot over each eye. The horns, although the specimen is a male, are remarkably small, and enclose the ears within their curve. If the ears are freed from their confinement, the animal becomes very uneasy, and never rests until he has succeeded in replacing them, which he cannot accomplish without considerable difficulty. He was presented to the Menagerie by Lord Liverpool about six years ago, and is extremely mild in his temper.

But especially are his best thanks due for numerous suggestions and much valuable assistance to his friend N. A. Vigors, Esq. A.M. F.R. and L.S., the zealous and talented Secretary of the Zoological Society. To that distinguished zoologist, whose extensive and intimate acquaintance with the animal kingdom at large, and particularly with its feathered tribes, is universally acknowledged, and to other leading Members of the Society to which he devotes his talents and his time, a work like the present appeared not ill adapted to advance the good cause in which they are engaged, the diffusion of knowledge. Under their auspices it was commenced, by their countenance it has been fostered, and it is with the sanction of their approval that it is now submitted to the public eye.

The beautiful birds represented above, which formed part of the Linnean genus Ardea, since subdivided into numerous distinct groups, offer the following generic characters. Their bill is conical, pointed, scarcely longer[226] than the head, and grooved along its upper surface; their head is ornamented with a crest of long and slender filamentous feathers, capable of being raised and depressed at pleasure; their wings are large and powerful; their legs are covered with large scales; the outer and middle toes are united at the base; and their claws are short and without denticulations.

Our birds are commonly allowed three dozen of small live plaice each per day.
