124 OF PERSPIRATION. 



cially of the Caucasian variety, there are great differ- 

 ences, and chiefly in connection with temperament, which 

 is found intimately and invariably connected with the 

 colour, abundance, disposition to curl, &c. of the hair;* 

 and there also exists a remarkable correspondence be- 

 tween the colour of the hair and of the iris. 



189. The direction of the hairs is peculiar in certain 

 parts, v. c. spiral on the summit of the head di- 

 verging upwards on the pubcs on the exterior of the 

 arm, as is commonly seen in some anthropomorphous 

 apes, (v. c. in the satyrus and troglodytes) running in 

 two opposite directions towards the elbow, i. e. down- 

 wards from the shoulder, upwards from the wrist ; to 

 say nothing of the eye-lashes and eye-brows. 



100. The hairs originate from the inner surface of 

 the corium, which abounds in fat. They adhere to it 

 pretty firmly/}- by a curious bulb, consisting of a double 

 involucrum ; I the exterior vascular and oval, the inte- 

 rior cylindrical, apparently continuous with the epider- 

 mis^ and sheathing the elastic filaments of which the 

 hair is composed, and which are generally from five, to

f I suspect that the bulb is intended for support rather than for nourishment* 

 from this circumstance, that the locks of hairs sometimes found in mclicera 

 and steatomata of the omentum and ovarium, some of which I have now before 

 me, arc usually destitute of bulbs, because they are not fixed, but lie naked in 

 the honey-like fatty matter.
