Hence this facial angle will indicate, with tolerable correctness, the proportion which the brain bears to the face,—the instrument of intelligence, to the receptacle of the organs of sense. 720. Of all animals, there are none in which the facial angle is so open as in Man ; and there exist, in this respect, great variations, even among the different a human races. Thus, in European heads, the angle is usually about 80° (Fig. 276). The ancient Greeks, in those statues of Deities and Heroes to which they wished to give the appearance of the greatest intellectual power, made it 90°, or even more, by the projection they gave to the forehead. On the other hand, in the Negro races, it is commonly about 70° (Fig. 277) ; in the different species of the Monkey tribe, it varies from about 65° to 30° (Fig. 278) ; and as we descend still lower, we find it becoming still more acute. In the Horse and Boar, for example, it becomes impossible to draw a straight line from the forehead to the upper jaw ; in con- sequence of the retreating character of the former, and the projection of the nose ; this will be evident from an ex- amination of Fig. 279. In Birds, Reptiles, and Fishes, the facial angle, when it can be measured, is found to be fig. 27S—Skull of Boar. still further Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Carpenter, William Benjamin, 1813-1885.
