. Animal physiology. Physiology, Comparative. SIZE OF BRAIN -. — FACIAL ANGLE. 549. Fig. 29L—Skull of European. almost all those persons who have been eminent for the amount of their acquirements, or for the influence they have obtained by their talents for command over their felloAV-men, have had large brains : this was the case, for example, with Newton, Cuvier, and N'apoleon. 719. The size of the brain, and especially of its anterior lobes (which seem particularly connected with the higher reasoning powers), as compared with that of the face, may be estimated pretty correctly by the measurement of the facial angle; as proposed by Camper, an eminent Dutch naturalist. This is done by drawing a horizontal line (cd, figs. 291 and 292), between the entrance to the '^ ear and the floor of the nose, so as to pass in the direction of the base of the skull; this is met by another line {a, h) which passes from the most prominent part of the forehead to the front of the upper jaw. It is evident that this last will be more inclined to the former, so as to make a more acute angle with it, in pro- portion as the face is more developed and the forehead more retreating; whilst it will approach more nearly to a right angle, if the forehead be prominent, and the muzzle project but little. Hence this facial angle will indicate, with tolerable correct- ness, 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 in this respect, even among the different human races. Thus, in European heads, the angle is usually about 80° (fig. 291). '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 ^.^ of negro. gave to the forehead. On the other hand, in the Negro races, it is commonly
