158 Explanation of P articulate Inheritance 



small part of it, and so much the more since the effects 

 produced by this particular group of germinal anlagen 

 must combine with those produced by all the others both 

 antecedent and subsequent. 



It would amount to the same thing if this given group 

 of specific anlagen differed from the corresponding group 

 of the other germinal substance not only quantitatively 

 but also qualitatively to a certain extent. 



We believe the final result to be that we can affirm 

 that the hypothesis of a heterogeneous germinal sub- 

 stance whose anlagen do not all enter into action from the 

 first moment of development, but rather become active 

 successively one by one, throughout the entire course of 

 development, explains the phenomena for which pre- 

 formistic germs were especially devised quite as satis- 

 factorily as they do, and at the same time is not open to 

 any of the formidable objections, which demonstate with 

 certainty the untenability of the hypothesis of pre- 

 formistic germs.
