188 SPREAD OF EVOLUTION. [1863. 



sterile varieties. His Geology is obscure ; and I rather doubt 

 about man's mind and language. But it seems to me ad- 

 mirably done, and, as you say, " Oh my," about the praise of

 time, but I have been asked more than a dozen times to 

 recommend something for a beginner and could only think of 

 Carpenter's Zoology. I am sure that a striking Treatise 

 would do real service to science by educating naturalists. If 

 you were to keep a portfolio open for a couple of years, and 

 throw in slips of paper as subjects crossed your mind, you 

 would soon have a skeleton (and that seems to me the diffi- 

 culty) on which to put the flesh and colours in your inimitable 

 manner. I believe such a book might have a brilliant success, 

 but I did not intend to scribble so much about it.
