The Journal of Heredity 



and green branches from variegated 

 plants produced only green offspring. 

 White branches ]jroduced only white 

 offspring when self fertilized. Cross 

 fertilization was not attempted. It is 

 likely that the variegated j^lants which 

 do appear come from a cross l)ctween 

 green and white gametes. Probably 



the heredity of this plant belongs to the 

 type of variegated chimeras of Pelar- 

 gonium zonale described by Baur (4). 



In conclusion I wish to express my 

 thanks to Dr. Ernst A. Bessey and 

 Prof. Henri Hus for their helpful en- 

 couragement and many \-aluablc sug- 

 gestions.

Eugenics and Genius 



If anyone could devise for us a means by which the genius, potentially existing 

 at any time, were realized, he would have jjerfonned in effect a serx-icc equivalent 

 to that of which eugenics repudiates the present ])ossibility — ^the actual creation 

 of genius. * * * g^^ \[ eugenics can raise the average level of human intelli- 

 gence, in so doing not merely does it render more likely, as Mr. Galton points out, 

 the production of men of the highest ability, but it provides those conditions in 

 which men of genius, now swainped, can swim. We could not undertake to jiroduce 

 a Shakesijcare, but we might reasonably hope to produce a generation which would 

 not destroy its Shakcspeares. And even if men of genius still fotind it necessary, 

 as men of genius have found it necessary, to "play to the gallery," they would 

 play, as Mr. Oalton says of the demagogue in a eugenic age, "to a more sensible 

 gallery than at present'"— C. W. Salecby: Parenthood and Race Culture (1909).
