My dear Sir

I remember the proofs of Title, Index &c. reaching me, and I thought I had returned one set to Messrs Clowes, for I certainly sent off the duplicates to Germany and Russia.² Perhaps I forgot to send them to Messrs. Clowes, and am sorry if this was the case. There was nothing to correct and you may bind the vols. as soon as you like. I think a smooth green cover would be best, but I do not care. I should greatly prefer the pages being cut. About the lettering on the back, I hardly know what to say: would

Or what you think best.³

I thank you sincerely for anticipating my note of yesterday about the Messrs Appletons: please remember that the Hel: Plates without the stereotypes of text and blocks would be of no use to them.⁴ They fear other publishers getting into the market before them: I should have thought this impossible from the Heliotypes; but Kowalovsky tells me that there were two pirated editions of my Descent of Man published in Russia, with a few new woodcuts, and much of text omitted, and yet that these injured greatly the sale of his Translation;—and he fears the same for present Book.⁵ I forgot to say that I have no special intentions about folding the Plates, except so as to avoid the folds crossing the faces: There are printed instructions about their situation.⁶

Yours very sincerely | Ch. Darwin.
