I. PRIMATES or _Nobles_: Mammalia furnished with fore teeth, of which there are four in the upper jaw, and two pectoral mammae. II. BRUTA: No fore teeth in either jaw. III. FERAE, _Beasts of Prey_: The fore teeth conical, usually six in each jaw. IV. GLIRES or _Gnawers_: Two chissel-shaped fore teeth in each jaw. V. PECORA, _Cattle_: No fore teeth in the upper jaw, several in the lower. VI. BELLUAE: Fore teeth obtuse; feet furnished with hoofs. VII. CETE, _Whales_: Pectoral fins in the place of feet, and in place of a tail the hind feet united so as to form a flat fin; no claws; the teeth cartilaginous. The order _Primates_ contains four genera:-- 1. _Homo_, _Man_, of which (strange to say) he makes two species, viz. _Homo Sapiens_, including all the descendants of Adam, and _Homo Troglodytes_, the orang-outang! The varieties of the human race are the American, the European, the Asiatic, the African or Negro, and those called monstrous, such as the Patagonians, characterized by their great size, the flat-headed Indians of Canada, &c. His description of the human figure is amusing; and as it may afford an idea of his mode of viewing objects, we shall translate it in part:-- "The _Body_ erect, bare, sprinkled over with a few distant hairs, and about six feet high. The _Head_ inversely egg-shaped: scalp covered with longer hairs: the fore part obtuse, crown very obtuse, hind-head bulging. The _Face_ bare: _Forehead_ flattish, square, compressed at the temples, ascending at the corners among the hair. _Eyebrows_ somewhat prominent, with hairs closely set and directed outwards, separated by the flattish glabella. Upper _eyelid_ moveable, lower fixed, both pectinated with projecting somewhat recurved hairs. _Eyes_ round: pupil round, without nictitant membrane. _Cheeks_ bulging, softish, coloured, their lower part somewhat compressed, the buccal portion looser. _Nose_ prominent, shorter than the lip, compressed, higher and more bulging at the tip; nostrils ovate, hairy within, with a thickish margin. Upper _lip_ nearly perpendicular, grooved in the middle; lower _lip_ nearly erect, more prominent. _Chin_ protruded, obtuse, bulging. _Mouth_ in the male bearded with bristles, which on the chin especially form a bundle. _Fore teeth_ in both jaws sharp edged, erect, parallel, close; _canine teeth_ solitary, a little longer, close to the rest on both sides; _grinders_ five, bluntish. _Ears_ lateral; auricles roundish-semilunar, pressed in some measure towards the head, bare, vaulted above the margin; bulging and soft below." He then proceeds to state more particularly, that there is no tail, and that the thumb is shorter and thicker than the fingers. Man, therefore, differs from other animals, as he says, in having the body erect and bare, although the head and eyebrows are covered with hair, two pectoral mammae, a brain larger than
