GENERAL CONCLUSIONS. 31 



Hybrids may in certain cases be bred 

 into the type of either parent, but 

 characteristics of the discarded race 

 occasionally appear, even in remote 

 descendants. 



Every race has an instinctive aversion to 

 mate with any other race. 



The development of a race in physique, 

 character, or mental qualities cannot go 

 beyond a full expression of the capacity 

 of its life -force. 



Every race differs specifically from any 

 other race, not only in physical type 

 but also in character ; and individuals 

 of the same race differ from each other 

 in expression of the same type. 



Development in physical type, or in 

 character, is limited to a full ex- 

 pression of the life - force with which 

 each race or individual was originally 

 endowed. 



The physique and intellectual qualities 

 of a parent may be dissociated from 

 each other in the offspring.
