interpretations of heredity, I am accustomed to 

 say: 



"Read Darwin first, and gain a full compre- 

 hension of the meaning of Natural Selection. 

 Then read the modern Mendelists in detail. But 

 then go back again to Darwin." 



Bear in mind Professor J. M. Coulter's com- 

 ment that "Mendelism has extended from its 

 simple original statement into a speculative 

 philosophy," and try for your own satisfaction 

 to separate the usable formula? from the intricate 

 vagaries of the new creed of heredity. 



Let me cite a recent assertion of Professor 

 William E. Castle, himself one of the foremost 

 experimenters along the lines of the newest 

 theory: 



"As to how a new race is begotten we have not 

 got much beyond Darwin; indeed many of us 

 have not got so far." 



The man who has got as far as Darwin in the 

 matter of understanding racial origins to say 

 nothing of getting beyond him even in our day, 

 is no tyro in the study of heredity. 



Read Darwin first; then read the 

 modern Mendelists; and then go 

 back to Darwin.
