HEREDITARY TRANSMISSION AND VARIATION. 95 



however similar, thev will alwavs differ in some cer- 

 tain particular. 



Now let us go back to Atavism, — to the hereditary 

 tendency I spoke of. What will come of a variation 

 when you breed from it, when Atavism comes, if I may 

 say so, to intersect variation ? The two cases of which I 

 have mentioned the history, give a most excellent illus- 

 tration of what occurs. Gratio Kelleia, the Maltese, 

 married when he was twenty-two years of age, and, as I

 her thumbs were deformed, showing a tendency toward 

 the sixth. 



These children grew up, and when they came to 

 adult years, they all married, and of course it happened 

 that they all married five-fingered and five-toed persons. 

 Now let us see what were the results. Salvator had 

 four children ; they were two boys, a girl, and another 

 boy : the first two boys and the girl were six-fingered 

 and six-toed like their grandfather ; the fourth boy had 

 only five fingers and five toes. George had only four 

 children : there were two girls with six fingers and six 

 toes; there was one girl with six fingers and five toes 

 on the right side, and five fingers and five toes on the
