relation. Forms or growths which are inseparably 

 joined with each other in one group of animals, 

 are wholly divorced from each other in another 

 group ; whereas Forms which have adapted cor- 

 relations to external conditions, are repeated over 

 and over again across the widest gaps in the scale 

 of Natural Affinity. 



If, then, it be true that New Species are created 

 out of small variations in the form of Old Species, 

 and this by way of Natural Generation, there must 

 be some bond of connexion which determines 

 those variations in a definite direction, and keeps 

 up the External Correlations pari passu with the 

 Internal Correlations. Natural Selection can have 

 no part in this. Natural Selection seizes on these 

 External Correlations when they have come to be. 

 But Natural Selection cannot enter the secret 

 chambers of the womb, and there shape the 

 new Form in harmony with modified conditions of 

 external life. How, then, are these external cor- 

 relations provided for beforehand ? There can be 

 but one reply. It is by Utility, not acting as a 

 Physical Cause upon organs already in existence, 

 but acting through Motive as a Mental Purpose
