 do so the law would prevent us from breeding 

 brother and sister together to get the Mendelian 

 segregation. Up to the present it has not been 

 shown that we can get pure whites and pure 

 blacks by breeding Mulattos together. Also, we 

 are not particularly interested in inches in height, 

 color of hair, or shape of physical organs, and 

 these are the things with which the Mendelian 

 theory deals. In a political campaign, the politi- 

 cal orator, in bringing forward the merits of his 

 candidate, does not say : "Vote for my man, he 

 has brown eyes and curly hair, and is much 

 superior to the other fellow, who has red hair 

 and a pug nose." 



We are interested in improvements in mental 

 power, physical strength and endurance, vitality, 

 resistance to disease, and longevity. These are 

 not unit characters at all, and consequently do 

 not come under the Mendelian theory. On this 

 point I will refer the reader to the New York

A eugenic theory based on either the Darwin-

 on a fallacy. Those theories relate to matters 

 of no consequence in the rise of man from a
