greater uniformity of physical and moral type than any of the other great divisions of mankind. By the nearly unanimous consent of anthropologists this type occupies at the same time the lowest position in the evolutionary scale, thus affording the best material for the comparative study of the highest anthropoids and the human species. The chief points in which the Negro either approaches the Quadrumana or differs most from his congeners are: 

 (1) The abnormal length of the arm, which in the erect position sometimes reaches the knee-pan, and which on an average exceeds that of the Caucasian by about 2 inches. 

 (2) Prognathism, or projection of the jaws (index number of facial angle about 70, as compared with the Caucasian 82). 

 (3) Weight of brain, as indicating cranial capacity, 35 ounces (highest gorilla 20, average European 45). 

 (4) Full black eye, with black iris and yellowish sclerotic coat, a very marked feature. 

 (5) Short flat snub nose, deeply depressed at the base or frontal suture, broad at extremity, with dilated nostrils and concave ridge. 

 (6) Thick protruding lips, plainly showing the inner red surface. 

 (7) Very large zygomatic arches—high and prominent cheek bones. 

 (8) Exceedingly thick cranium, enabling the Negro to butt with the head and resist blows which would inevitably break any ordinary European's skull. 

 (9) Correspondingly weak lower limbs, terminating in a broad flat foot with low instep, divergent and somewhat prehensile great toe, and heel projecting backwards ("lark heel"). 

 (10) Complexion deep brown or blackish, and in some cases even distinctly black, due not to any special pigment, as is often supposed, but merely to the greater abundance of the coloring matter in the Malphigian mucous membrane between the inner or true skin and the epidermis or scarf skin. 

 (11) Short, black hair, eccentrically elliptical or almost flat in section, and distinctly woolly, not merely frizzly, as Prichard supposed on insufficient evidence. 

 (12) Thick epidermis, cool, soft, and velvety to the touch, mostly hairless, and emitting a peculiar rancid odor, compared by Pruner Bey to that of the buck goat.   [11]
