CROSSING AND CLOSE-INTERBREEDING. 241 



principally, because they show that Reversion ex- 

 plains the seemingly-inexplicable results of Crossing, 

 of Close-Interbreeding, and of Self-Fertilization, even 

 when there prevail such infinite variations in the quan- 

 tity and quality of those results, as are known to obtain 

 with Plants. 



Numberless other evidences, — showing that any de- 

 parture from the type of the sum of all the positive 

 characters of the species, is fraught with proportional 

 evil upon the aggregate, as well as upon the parts in- 

 volved, and showing that any (proportionate) return to 

 the perfect type (however effected), issues in an abate- 

 ment of such evil, — could be furnished from Darwin's 

 own notes of the breeding of Dogs, Rabbits, Bees 

 and, in fact, of all the domestic animals. The reader, 

 however, will doubtless concur in the opinion that, 

 after the testimony adduced in relation to the Cross- 

 ing, Close-Interbreeding, and Self-Fertflization, respec- 

 tively, of Plants, Pigeons, Fowls, Pigs, Horses, Sheep, 

 and Cows, all further proofs, in support of the theory 

 of Reversion, and in Refutation of Darwinism, may 

 justly be dispensed with.
