My dear Sir

I am glad to answer your queries as fully as I can.¹ I have corrected the whole of the little book (about 320 pages large type, with 15 wood-blocks) once over, & half of it the second time.² I believe my Printers will not strike off any copies until the whole is finally corrected, but this will now be soon done.—³ I have already ordered copies of clean-sheets to be sent me, by instalments, as soon as ready, one set for you for the translation of the book, & another for E. Krause to judge by.—⁴

The subject has been to me a “hobby-horse”, & I have perhaps treated it in foolish detail. Anyhow, as I told Krause, I do not think that any part would be fit for Kosmos; but I have left the matter in his hands to do exactly what he thinks best, & I really feel incapable of advising.⁵ Krause must look over the sheets & settle what he thinks best.—

I am very sorry that your outing has done you no good, & earnestly hope that your longer vacation may benefit you.—⁶

My dear Sir | Yours very sincerely | Charles Darwin
