Just as followers of Weissmann were obliged 

 to shift their ground to meet the evidence 

 brought by new experiments, until finally all 

 that remained of their doctrine had been sub- 

 stantially harmonized with and blended into the 

 broader and earlier theories of Darwinian hered- 

 ity, only the doctrine of continuity of the germ 

 plasm remaining as a permanent acquisition; so 

 the attempt to make "Mendelism" comprehend 

 the entire subject of heredity, has necessitated a 

 perpetual modification of the point of view, and 

 an amplification of the terminology to meet the 

 facts of more comprehensive experiments, until 

 Mendelism has come to be harmonized with and 

 blended in the more comprehensive knowledge 

 of heredity, leaving only the formula? associated 

 with dominance and recessiveness to mark the 

 individual contribution of Mendel to the all- 

 comprehending subject of heredity.
