7. 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 will be of real service to 
you. 
October 15. 
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 you 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 
Mitchella.
