288 THE GLANDS REGULATING PERSONALITY 



a good deal of hair on his body, his skin is a pale tan-pink, his 

 lips are thin, and his no the definite bridge which 



narrows it. The Mongol, like the Negro, has the hairless body 

 and the beaidlen face, but unlike him baa lank straight hair 

 on his head, while his features are flattened and fore-shortened. 

 Upon the basis of these structural, functional and mental 

 differences, the qualitative and quantitative evolution of which 

 in the race as in the individual is guided by the glands of internal 

 ration, Keith presents a very good case for the view that the 

 white man is an example of relative excess of the pituit 

 thyroid, adrenal and gonad endocrines. "The sharp and pro- 

 nounced nasalization of the face, the tendency to strong eyebrow 

 ridges, the prominent chin, the tendency to bulk of body, and 

 height of stature in the majority of Europeans" are the sipns of 

 pituitary dominance. Keith is also of the opinion that "the sex- 

 ual differentiation, the robust manifestations of the male charac- 

 ters, is more emphatic in the Caucasian than in either the Mongol 

 or Negro racial types ... in certain negro types, especially in 

 Nilotic tribes, with their long stork-like legs, we seem to have 

 a manifestation of abeyance in the action of the interstitial 

 glands." As for the adrenal superiority of the white man, "it is 

 150 years since John Hunter came to the conclusion . . . that 

 the original color of man's skin was black, and all the knowledge 

 that we have gathered since his supports the inference he drew. 

 From the fact that pigment begins to collect and thus darken 

 the skin when the adrenal bodies become the seat of a destruet 



ase we infer that they have to do with the clearing away of 

 pigment, and that we Europeans owe the fairness of our skins to 

 some particular virtue resident in the adrenal bodies." Finally, 

 as regards the thyroid, a comparison of the face of a eretin with 



f of the Negro or Mongol tells the story. A certain van.
