1 88 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 

 the ' Origin.' I can't help liking it, which makes me rather 

 ashamed of myself."

 answered, " he has just written a great book on the skull." " I 

 don't call that a book," she replied, and added, " I want

 Now, with your ease in writing, and with knowledge at your 

 fingers' ends, do you not think you could write a popular 

 Treatise on Zoology ? Of course it would be some waste 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.

 admires Tennyson, I must call her attention to two sweetly 

 pretty lines (p. 105) . . .
