combination of traits which are by no means invariable 

 characteristics. Thus, while members of the White race 

 are usually fair-skinned, we find that there are gradations 

 from a dark skin tint that is almost black, all the way 

 through the various degrees of blondness to a yellowish 

 colored skin; while most members of the White race are 

 neither very broad headed nor very long headed, there are 

 individuals who are as long headed as the Negro and oth- 

 ers who are as round headed as the Chinaman; in hair 

 form, the members of the White race show variations all 

 the way from straight almost lank hair to frizzly or almost 

 kinky hair. The White race seems therefore to be more 

 variable than either of the other two great divisions of 

 mankind. 



Because the White race seems to be more variable in 

 its traits than either of the other two races, Professor 

 Giddings considers that it is the most direct projection 

 of the original race, that it is the variable plastic race 

 coming down from earliest paleolithic times. He main- 

 tains that this hypothesis is the simplest and agrees with 

 more facts than any other theory of race origin. He ac- 

 counts for the origin of the Yellow and Black races upon 

 the hypothesis that one contingent of the original non- 

 descript race with a tendency to vary, worked its way 

 into a favorable location, where, in the course of cen- 

 turies, natural selection operated to make it markedly 

 dolichocephalic, frizzly-haired, and black; while another 

 contingent of this original plastic race with a tendency 

 to vary, worked its way into a favorable location, and 

 there, in accordance with the same selective process, be- 

 came markedly brachycephalic, almond-eyed, lank-haired, 

 and yellow in skin color. While this theory does not take 

 immediate notice of color gradations such as brown,
