has ever been attempted as that here presented, and it should 

 be a matter of some surprise that there is as close an approach to 

 complete dominance as there appears to be. 



In a subsequent paper the writer intends to carry out a study of 

 inheritance of smaller groups of integral variates and of single 

 units. The results of this study might be anticipated to the extent 

 of saying that they strongly support the conclusions expressed in 

 the present paper, and especially those regarding the alternative 

 character of the inheritance of meristic variates.
