OP PERSPIRATION. 121 



181. Our colour resides in it. In all persons the 

 corium is white, and, in almost all, the cuticle white and 

 semipellucid, though in Ethiopians it inclines to grey. 

 But the mucous reticulum varies after birth, with age, 

 mode of life, and especially with difference of climate. 



Thus among the four varieties into which I would 

 divide the human race, in the first, which may be 

 termed Caucasian and embraces Europeans (except the 

 Laplanders and the rest of the Finnish race), the western 

 Asiatics, and the northern Africans, it is more or less 

 white. 



In the second or Mongolian, including the rest of the 

 Asiatics (except the Malays of the peninsula beyond the 

 Ganges), the Finnish races of the north of Europe, as 

 the Laplanders, &c. and the tribes of Eskimaux diffused 

 over the north of America, it is yellow or resembling 

 box wood. 



In the third — the Ethiopian, to which the remainder 

 of the Africans* belong, it is of a tawny or jet black. 



In the fourth or American, comprehending all the 

 Americans excepting the Eskimaux, it is almost copper 

 coloured, — of a dark orange or ferruginous hue. 



In the fifth or Malaic, in which I include the inhabi- 

 tants of all the islands in the Pacific Ocean, and of the 

 Philippine and Sunda, and those of the' peninsula of 

 Malaya, it is more or less tawny, — between the hue of 

 fresh mahogany and that of cloves or cfresnuts.
