CONCLUDING REMARKS. 445 



individual, of all the lost or reduced characters — the 

 evil results from close-interbreeding correspond most 

 faithfully, degree for degree, with the disproportionate 

 development of the individuals — the variations in the 

 quantity of the effects observed, tallying exactly with 

 the variations in the quantity of cause assigned. 



The modes of Man's Selection which thus vary the 

 evil results, may be conveniently classed as four : viz., 



a. That mode of Selection which, while it re-devel- 

 opes all or most of the lost or reduced characters of a 

 given species, does not develop them all in the same 

 individuals, or in the same variety; but, instead there- 

 of, apportions or distributes them among different va- 

 rieties, thereby causing each variety of said species to 

 lack the many important characters which constitute 

 the peculiarities of the other varieties of the same 

 species, and thereby restricting such variety to one 

 only of the recovered characters, which is pushed to 

 an extreme of development which aids the more to 

 mar the true proportion. 



This process of Selection is exemplified in the case 

 of the Pigeon, and of the Fowl. 



In consequence, therefore, of each variety of either 

 of these species, lacking the characters, which have 

 been appropriated as peculiarities by the other varie- 

 ties of the given species, and in consequence of the 

 extreme, disproportionate development of the special 

 excellence of each variety, it was to be expected, that 

 the interbreeding of individuals of each such variety, 

 would be prolific of great evil results. This expecta- 

 tion has been fully justified by the facts, from Darwin,
