C. Darwin to T. H. Huxley. 



Down, Nov. 22 [1860]. 



MY DEAR HUXLEY, For heaven's sake don't write an 

 anti-Darwinian article ; you would do it so confoundedly 

 well. I have sometimes amused myself with thinking how 

 I could best pitch into myself, and I believe I could give two 



or three good digs ; but I will see you first, before I will 



try. I shall be very impatient to see the Review.* If it 

 succeeds it may really do much, very much good. .... 



I heard to-day from Murray that I must set to work at 

 once on a new edition f of the ' Origin.' [Murray] says the 

 Reviews have not improved the sale. I shall always think 

 those early reviews, almost entirely yours, did the subject an 

 enormous service. If you have any important suggestions or 

 criticisms to make on any part of the ' Origin,' I should, of 

 course, be very grateful for [them]. For I mean to correct as far 

 as I can, but not enlarge. How you must be wearied with 

 and hate the subject, and it is God's blessing if you do not 

 get to hate me. Adios.
