VIRILE SENTIMENT 77 



And we note that the number of albinoes and pig- 

 mented individuals, i.e., 4 and 11 respectively, is as 

 near as it can be to the expected 4 : 12 ratio. This 

 case, then, must be accepted as demonstrating the 

 existence of the processes of segregation and gametic 

 purity in the hereditary transmission of at least one 

 other human character. 



Let us consider another case of albinism, but this 

 time among Europeans. In a Swiss village there 

 once lived an albino, Josephine Chassot. She never 

 married, and for three generations back her ancestors 

 were apparently normal people. But in her own 

 generation she had ten cousins in the second degree.* 

 Of these, three were albinoes, and the remaining 

 seven were all apparently normal. All the normal 

 ones appeared in one family, and all the three albinoes 

 in another. In this latter family it is known that 

 there were normal members, but the number is 

 unknown. One of the normal cousins of Josephine 

 married a normal woman, and had twelve children, 

 eight being normal and four albinoes. Now this 

 case, apparently remarkable because of the sporadic 

 appearance of the albinoes, is entirely explicable on 

 the Mendelian explanation of segregation and gametic 

 purity. The families concerned lived in two Swiss 

 villages half a league from each other, and we may 

 suppose that at the time {i.e., sixty years ago) travel- 

 ling was difficult, and intercourse with more distant 

 villages was more or less a rare event. Under such 



* That is to say, they were the children of two pairs of parents, one 

 of whom in each pair was a cousin of one of her parents.
