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 formulae 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. 



Bead Darwin first; then read the 

 modern Mendelists; and then — go 

 back to Darwin.
