HEREDITY AND "ARRANGEMENT ' 127 



the peculiarity may have been also possessed by 

 some other member of the family. But on the 

 whole the offspring does closely resemble its 

 parents ; that is to say, not only the species and 

 the variety but the individual " breeds true." 

 " Look like dey are bleedzed to take atter der 

 pa," as Uncle Remus said when he was explaining 

 how the rabbit comes to have a bobtail. More- 

 over this resemblance is not merely in the great 

 general features. Apart from monstrosities, the 

 children of human beings are human beings ; the 

 children of white parents have white skins, those 

 of black progenitors are black. Commonly, 

 though not always by any means, the children of 

 dark-haired parents are themselves dark-haired, 

 and so on. But smaller features are also trans- 

 mitted, and transmitted too for many genera- 

 tions ; for example, the well-known case of the 

 Hapsburg lip, visible in so many portraits of 

 Spanish monarchs and their near relatives, and 

 visible in life to-day. Again, there are families in 

 which the inner part of one eyebrow has the 

 hairs growing upwards instead of in the ordinary 

 way, a feature which is handed on from one 

 generation to another. Even more minute 

 features than this have been known to be trans- 

 missible and transmitted, such as a tiny pit in the 

 skin on the ear or on the face. In fact, there is 

 hardly any feature, no matter how small, which 

 may not become a hereditary possession. 



If in-and-in breeding occur, as it may do 

 amongst human beings in a locality much removed 

 from other places of habitation, it may even
