My dear Sir

You have been extraordinarily kind in taking so much trouble for me.¹ Your account this morning has been so satisfactory, that I have written to M. Talandier to agree to his proposal.² It is an immense advantage to any scientific work and subject to be translated into French, as it can then be read in any country. I am a very poor French scholar, though I read it with fluency, and it would no doubt be an immense advantage if you were to read over the proofs; but then I know how hard you are worked, and I have scruples about accepting your extremely kind offer. Indeed it is too much; but perhaps you would not object to look at any passage which seemed to me doubtful.—

With my hearty thanks to you and M^rs. Cresy | Believe me, Yours very sincerely | Charles Darwin

I am very much pleased at what you say about my Book in your first note.— You have praised exactly what pleases me most to be praised.
