Colouration in Animals and Plants. 



This exquisitively written passage the writer was quite unaware 

 of having read, though he possessed and had perused the work 

 quoted, nor can he understand how such an admirable exposition 

 could have escaped notice. Had he read it : had he assimilated it 

 so thoroughly as to be unconscious of its existence ; is this a case of 

 rapid growth of automatism *? He cannot say. 



To return to the main point, it would seem that specialization is 

 directly proportionate to activity, and when we compare the infinitely 

 diverse organization of the animal with the comparative simplicity 

 of the vegetable world, this conclusion seems to be inevitable.
