172 THE' FORMATION OF VARIETIES. 



his chapters on Analogous variation, shows to be 

 capable of developing all of the positive characters of 

 its species. But, the way varieties are formed, and 

 formed so distinct, is, by Man's selection repressing 

 this capacity in every direction, or in every character, 

 and suffering it to be exercised in only the one charac- 

 ter which Man assigns as the peculiar character of the 

 variety, in which the individual has been placed. Dar- 

 win says, as has been before quoted, 



" That we may infer, that, when any part, or organ, 

 is either greatly increased in size, or wholly suppressed, 

 * * the coordinating power of the organization will 

 continually tend to bring all the parts again into har- 

 mony with each other." 



If this be the tendency of the coordinating power of 

 the organization, which it unquestionably is, it is mani- 

 fest, that the system of man's formation of varieties, 

 under domestication, — namely, of increasing, to a great 

 size, the peculiarity of each variety, and of suppressing, 

 or reducing, the other parts in the same variety, — is in 

 derogation of this power, which " tends to bring all of 

 the parts again into harmony with each other." The 

 object of this chapter, is to see how, and how far, man 

 has violated the normal, mutual relation of the parts. 

 After having shown the many ways, in which he has 

 varied the normal relation of the parts of a species, we 

 shall proceed to show that Darwin is wrong, when he 

 fancies, that man may mould an organism into any 

 form he pleases, and yet not injure the individuals in 

 a physiological sense. In this connection, he says 

 (Vol. ii, p. 425):
