 general co-ordinating power above referred to, which 

 does more or less influence all forms of life. Again, 

 instead of looking upon .^organic polarity' as an ever 

 potent, co-ordinating power, which must infallibly 

 co-operate in producing the results that happen to 

 be initiated by any cause of change whatsoever, Mr. 

 Darwin seems to regard it as a more or less occa- 

 sional cause of changes otherwise unaccountable — 

 of which he gives many highly interesting examples 

 under the head of ^ Correlated Variability ^.'

^ As we have previously stated (p. 594), Mr. St. George Mivart is 

 also strongly impressed with the inadequacy of Natural Selection for 

 occupying the all-important position assigned to it by Mr. Darwin. He 

 has expressed his belief that there is some deep underlying and in- 

 ternal cause of change to which the influence of Natural Selection is 

 subordinate. Although we cannot agree with Mr. Mivart's teleological 

 views, we do agree with him as regards the importance to be attached to 

 these internal causes of change. In one of the most interesting chapters
