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;* 

 aud 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 pubes — 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 vris(; to 

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



190. The hairs originate from the inner surface of 

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

 pretty firmly ,f by a curious bulb, consisting of a double 

 involucrum ; ;{; — the exterior vascular and oval, the inte-

t I suspect that the bulb is intended for suntxut rather than for nourishment, 

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

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

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

 tiie honey-like fatty matter.
