My dear Häckel

I received this morning your present of the new Edit. & of twoEssays.f2 I see in one of these you, as usual, pile honours high on myhead.— As I leave home tomorrow morning for more than a week, Ihave thought that I would not delay in thanking you.—f3 I am delightedfor the sake of science & the public, & likewise for your own sake,to see the new Edition, which seems very greatly enlarged & I do notdoubt in all ways improved. For my own especial self, it makes me groana little, for my M.S is completed, so that I cannot profit by yourimprovements & additions:f4 it would, alas, from my wretched knowledge ofGerman take me a very long time to read the new Edition carefully.

In what I am going to send immediately to the Printers, I havetried to a certain extent to keep on distinct ground from you,& have much shortened some of the subjects which you have fully treated,& refer my readers to your works.f5 And I hope before very long yourMorphologie Gen: will be accessible to English Readers.f6

I do not know how my Book & your Book will be received by the English:I observe at present that there is some tendency to decry geneologicalclassification.— I have been rather better of late, & have workedharder than usual; but I suppose that my best day’s work is notone-third of what you can do. You seem a most indomitable worker.—I have seen no scientific man for a long time, except, about a monthago, Kölliker, whom I liked extremely.f7

Do not work too hard, & believe me, my dear Hackel with the sincerestesteem— yours very truly | C: Darwin
