 less capable ones. And yet some very good 

 races, possibly with capacities for high social 

 and intellectual development, have been com- 

 pletely exterminated, as for instance the Luca- 

 yan Indians of the West Indies, and the 

 aborigines of Tasmania. 



Few animals have suffered more wholesale 

 destruction than have the more primitive races 

 of men in different parts of the earth. Several 

 species of man have become entirely extinct,
