JST. 51.] TO CHARLES DARWIN. 489 



perfect appreciation and happy use of Natural Selec- 

 tion, and the very complete analogy between diversi- 

 fication of species and diversification of language. I 

 can hardly think of any publication which in England 

 could be more useful to your cause than this volume 

 is, or should be. I see also with what great effect 

 you may use it in our occasional discussion about 

 design ; indeed I hardly see how to avoid conclusion 

 adverse to special design, though I think I see indi- 

 cations of a way out. 



Depend on it, Max Miiller wiU be of real service to 

 you. 



Ootolaer 13. 



I have been so much occupied that I deferred to 

 the last moment to write out my second notice of your 

 Orchid book for " Silliman's Journal." I wrote out 

 Saturday evening what I could, and to-day have 

 finished and sent off my manuscript to New Haven. 

 The greater part consists of a record of some of my 

 observations last summer, very hurriedly penned, and 

 sent off. I trust yoii will be pleased, and will think 

 that my little contributions cannot be better hatched 

 than under your wings. 



I hope that my young correspondent is fast recov- 

 ering strength. Tell him that I have no more stamps 

 for him yet, but shall pick up his desiderata one of 

 these days. 



I have some nice live roots of Cypripedium, two 

 or three species to send you, and mean to send 

 MitcheUa. 



How Hooker does praise up your book, in the 

 " Gardener's Chronicle ! "
