36 ANTHROPOID APES. 



The face, which is soon after birth of a flesh colour, 

 merging into a yellowish brown, assumes a darker 

 shade with the gradual development of the body. 

 The hairy coat is sleek, or only in rare cases slightly 

 curled, and the coarser and bristly hair is generally 

 stiff and elastic. The parting on the forehead is 

 often so regular that it might have been arranged 

 by the hairdresser's art (see Fig. 6). Close behind 

 that part of the head at which the projecting supra- 

 orbital ridges of the gorilla generally meet, there is 

 in the chimpanzee an altogether bald place, or only 

 a few scattered hairs. Eound the face the growth 

 of hair streams downwards like a beard. On the 

 neck it is from 60 to 80 or 100 mm. in length, and 

 it falls in the same long locks over the shoulders, 

 back, and hips. The hair on the limbs is not so 

 long, and takes a downward direction on the upper 

 arm, and an opposite direction on the forearm, while 

 there is often a longitudinal parting on the centre 

 of the inner surface of this part of the limb. On 

 the back of the wrist the hair grows in a kind of 

 whorl; the upper hairs turn upwards and backwards, 

 the middle ones turn backwards, the lower ones 

 backwards and downwards. The backs of the hands 

 and the roots of the fingers are hairy. On the 

 front of the thigh the hair takes a downward direc- 

 tion, wliile behind it grows backwards. On tiie 

 shank it grows downwards in the region of the 

 tibia, and turns back on the inside of the leg. 

 The back of the foot and the roots of the toes are 

 likewise hairy. There is a shorter growth of these 

 scattered hairs on the face, chin, and ears. On the
