The most approved classification of mankind is that of Blumenbach. He divides them into five varieties: 1. The Caucasian; 2. Mongolian; 3. Ethiopian; 4. American; and 5. Malay: and the following are the characteristics of each. I. THE CAUCASIAN. The skin white; the cheeks rosy--almost a peculiarity of this variety; the hair of a nut-brown, running on the one hand to yellow, on the other into black, soft, long, and undulating; the head symmetrical, rather globular; the forehead moderately expanded; the cheek-bones narrow, not prominent; the alveolar edge round, the front teeth of each jaw placed perpendicularly. The face oval and pretty straight; its features moderately distinct; the nose narrow and slightly aquiline, the bridge of it rather prominent; the mouth small; the lips, especially the lower, gently turned out; the chin full and round. This variety comprehends all Europeans, except the Laplander and the rest of the Finnish race; the Western Asiatics as far as the Obi, the Caspian, and the Ganges; and the people of the North of Africa. II. THE MONGOLIAN. Skin of an olive colour; the hair black, stiff, straight, and sparing. The head almost square, the cheek-bones prominent outwards; the superciliary arches scarcely perceptible; the osseous nostrils narrow; the alveolar edge arched obtusely forward; the chin somewhat projecting. The face broad and flattened, and its parts consequently less distinct; the space between the eyebrows very broad as well as flat, the cheeks not only projecting outward, but nearly globular; the aperture of the eyelids narrow and linear; the nose small and flat. This comprehends the remaining Asiatics, except the Malays of the extremity of the Transgangetic Peninsula, the Finnish races of the North of Europe, Laplanders, &c., and the Esquimaux, diffused over the most northern parts of America, from Behring's Strait to the farthest habitable point of Greenland. III. THE ETHIOPIAN. Skin black; the hair black and crisp. Head narrow, compressed laterally; forehead arched; the cheek-bones projecting; the osseous nostrils large, the jaws lengthened forward; the alveolar edge narrow, elongated, more elliptical; the upper front teeth obliquely prominent, the lower jaw large and strong; the skull thick and heavy; the face narrow, and projecting at its lower part; the eyes prominent; the nose thick and confused with the projecting cheeks; the lips, especially the upper, thick; the chin somewhat receding; the legs in many instances bowed. This comprehends the inhabitants of Africa, with the exception of the Caucasian variety which inhabits the northern parts. IV. THE AMERICAN.
