VARIATIONS, DUE TO REVERSION. 105 



theory purports to rest, invalidates that theory ; and, if 

 the filling up of that hiatus, with a known, scientific law, 

 diametrically opposed to the assumption essential to 

 such theory, is disproof of the theory; then, the evi- 

 dence already advanced, constitutes a Refutation of 

 Darwinism. But, the Refutation does not depend upon 

 such mere agreement, of the facts, with the hypothesis 

 of Reversion. Demonstrative proof of the truth of 

 the theory of Reversion is readily available ; which is 

 furnished, in the subsequent chapters, which treat of 

 Crossing, Close-Interbreeding, and Self-Fertilization.
