108 THE AMERICAN NATURALIST [Vol. LIII 



Here, of course, McCluer quite naturally overlooks tlie 

 fact of dominance, and adheres, although with a more 

 rational reason than most i)lant breeders of his time, to 

 the idea of fixation of typo tliroiioli tlie effects of selec- 

 tion. McCIuer, however. Iumc a- throughout his paper, 

 shows the inherent instincts of a geneticist, and his paper, 

 although an obscure contribution to the literature of plant 

 breeding, deserves special notice on that account.
