generation and the reappearance of the recessive 

 factor, beautifully segregated, in the second. 



Instances of inheritance of that order we have 

 had presented again and again. We shall hear 

 of more of them before we are through. 



But, in the meantime, let us not forget the 

 lesson taught by the Sunberry let us recognize 

 that there are conditions of hybridization under 

 which characters appear to be permanently 

 blended when first brought together; not mo- 

 mentarily linked in an unequal union to be segre- 

 gated in the next generation, but fixed in a new 

 and lasting combination that strikes a balance be- 

 tween the combinations presented by the parent 

 forms. 



It is possible, to be sure, to interpret this aspect 

 of heredity in Mendelian terms. Nor should we 

 deny altogether the validity of such application, 

 for we may well believe that there are gradations 

 all along the line, could we search them out, be- 

 tween the case of the sterile hybrid, born of 

 widely diverged parents, and the case of off- 

 spring of members of the same species that differ 

 only as to some varietal character. 



The same laws, could we fathom them in their 

 broader aspect, apply to each and every case. 



But, on the other hand, it is at least open to 

 question whether it would not be better to re-
