232 SPREAD OF EVOLUTION. [1866. 



would have been a sin if you had not done so. I am espe- 

 cially rejoiced as you give the arguments for occasional trans- 

 port, with such perfect fairness ; these will now receive a 

 fair share of attention, as coming from you a professed bota-

 success, and for Grove's sake at the brilliant success of the 



whole meeting. 



Yours affectionately, 



Charles Darwin.

 the connection which arose between my father and Professor 

 Victor Carus. The translation referred to is the third Ger-

 father's books into German. The conscientious care with 

 which this work was done was of material service, and I well

 at his own short-comings) with which my father used to 

 receive the lists of oversights, &c., which Professor Carus 

 discovered in the course of translation. The connection was 

 not a mere business one, but was cemented by warm feelings 

 of regard on both sides.] 



C. Darwin to Victor Carus. 



Down, November 10, 1866. 

 My dear Sir, — I thank you for your extremely kind 

 letter. I cannot express too strongly my satisfaction that you 

 have undertaken the revision of the new edition, and I feel 

 the honour which you have conferred on me. I fear that 

 you will find the labour considerable, not only on account of 

 the additions, but I suspect that Bronn's translation is very 

 defective, at least I have heard complaints on this head from
