VIRILE SENTIMENT ' 75 



ception of blending does not explain it, while that of 

 gametic purity and segregation enables us to form a 

 mental picture of the main line of the processes 

 concerned. The same segregation of eye-colour 

 occurs when distinct races of mankind are crossed. 

 Among my collection of human pedigrees I have 

 several of an European (usually a fair-complexioned, 

 light-haired, blue-eyed Scotchman) married to a Red 

 Indian woman, and of their descendants. When the 

 half-breeds from such a marriage marry an European 

 of a certain gametic structure, the fair complexion, 

 light hair, and the blue eyes segregate out again 

 among their children, 



I pass next to consider another character which 

 we cannot regard as pathological, but yet is not 

 normal. We may speak of it as abnormal. I allude 

 to the quality of albinism. It is a condition in which 

 there is a complete absence of pigmentation in the 

 body.* It is known not only among the less deeply 

 pigmented races of mankind, but also among the 

 intensely pigmented races, such as negroes. Mr. 

 Farabee has examined an interesting case of the 

 hereditary transmission of albinism among negroes. 

 An albino negro married a normally-pigmented 

 negress. There were three sons, all normally pig- 

 mented. All three married pigmented negresses, and 

 two of them had only the normally-pigmented off- 

 spring. The other son married twice, and in each 



* The pigments of the blood, bile, and of muscle are, of course, 

 excepted. It may perhajjs be better, for practical purposes, to define 

 an albino as an individual in whom there is absence of visible pig- 

 mentation.
