 your extraordinary labour is over ; if there is any fair amount 

 of truth in my view, I am well assured that your great labour 

 has not been thrown away. . . . 



I yet hope and almcst believe, that the time will come 

 when you will go further, in believing a very large amount of 

 modification of species, than you did at first or do now. Can 

 you tell me whether you believe further or more firmly than 

 you did at first ? I should really like to know this. I can 

 perceive in my immense correspondence with Lyell, who 

 objected to much at first, that he has, perhaps unconsciously 

 to himself, converted himself very much during the last six 

 months, and I think this is the case even with Hooker. This 

 fact gives me far more confidence than any other fact.

 ently begun to doubt about species. Is not Krohn * a good 

 fellow ? I have long meant to write to him. He has been 

 working at Cirripedes, and has detected two or three 

 gigantic blunders, .... about which, I thank Heaven, I 

 spoke rather doubtfully. Such difficult dissection that even 

 Huxley failed. It is chiefly the interpretation which I put on 

 parts that is so wrong, and not the parts which I describe. 

 But they were gigantic blunders, and why I say all this is be- 

 cause Krohn, instead of crowing at all, pointed out my errors 

 with the utmost gentleness and pleasantness. I have always

Krohn, one on the Cement Glands, marked that he " blundered dread- 



and the other on the development fully about the cement glands,"
