Farewell, yours affectionately, 



C. DARWIN.

Here is a pleasant genealogy for mankind.

Down, January 1 4th [1860]. 



... I shall be much interested in reading your man dis- 

 cussion, and will give my opinion carefully, whatever that 

 may be worth ; but I have so long looked at you as the type 

 of cautious scientific judgment (to my mind one of the 

 highest and most useful qualities), that I suspect my opinion 

 will be superfluous. It makes me laugh to think what a joke 

 it will be if I have to caution you, after your cautions on the 

 same subject to me ! 



I will order Owen's book;* I am very glad to hear 

 Huxley's opinion on his classification of man ; without 

 having due knowledge, it seemed to me from the very first 

 absurd ; all classifications founded on single characters I 

 believe have failed. 



. . . What a grand immense benefit you conferred on me 

 by getting Murray to publish my book. I never till to-day 

 realised that it was getting widely distributed ; for in a letter 

 from a lady to-day to E., she says she heard a man enquiring 

 for it at the Railway Station! ! ! at Waterloo Bridge ; and the 

 bookseller said that he had none till the new edition was 

 out. The bookseller said he had not read it, but had heard 

 it was a very remarkable book !!!....
