that of the blue Andalusian fowl, the qualities of the in- 

 dividual are markedly different according as to whether 

 he or she has received a single or a double dose of a given 

 factor. It is not inconceivable that some of the quali- 

 ties in which a man differs from a woman ar founded 

 upon a distinction of this nature. Certain qualities oi 

 intellect, for example, may depend upon the existence in 

 the individual of a double dose of some factor which is re- 

 pelled by femaleness. If this is so, and if woman is bent 

 upon achieving the results which such qualities of intellect 

 imply, it is not education or training that will help her. 

 Her problem is to get the factor on which the quality 

 depends into an ovum that carries also the factor for 

 femaleness.
