To detail our own views on the arrangement of this great order, would require more space than the nature of the present work would allow; it must suffice, therefore, to refer to the few hints which have been given in the details of the various genera. The four orders here indicated have a vague general character in common, which is not easy to define or even express : it partially consists in the magnitude of the head, as compared with the subsequent divisions generally; and a hind toe being always present, on the same plane with those in front, the great majority of them perch and traverse the boughs of trees with comparative facility, while the remainder are too obviously allied to admit of separation]. THE FOURTH ORDER OF BIRDS,— THE POULTRY, (Gallix.*:. Lin.)— Are so named from their affinity to the Domestic Cock, in common with which they have generally the upper mandible vaulted, the nostrils pierced in a large membranous space at the base of the beak, and covered by a cartilaginous scale. Their heavy carriage, short wings, and bony sternum (tig. 107), diminished by two emarginations so wide and deep that they occupy nearly its whole lateral portion, its crest being ob- liquely truncated in front, so that the sharp edge of [an appendage to] the fourchette is only joined to it by liga-
