My dear M^r. Darwin

I was so much occupied all day yesterday that I could not answer your kind note at once, as I ought to have done— I also am very glad that the work is at last finished, for it has been hanging about for a long time.—¹

As regards the money matters I hardly know what to say.— I think I estimated the translation of the article originally printed in “Kosmos’ at £15, & I suppose I did a good deal more than that, although you have hardly made use of so much.—² £20 would probably be a fair payment all things considered,—but if this is more than you choose to afford we can revert to the original sum.— I hope to be allowed to have a copy of the whole book when published to take its place with other writings of yours on my shelf.—³

With kind regards | Believe me | Yours very truly | W. S. Dallas
