My dear Sir

I wrote in such a hurry about the unfortunate error in the Manual,¹ in order to catch the Post, that I do not know whether I expressed myself intelligibly.— If you knew what pains I took to make the Instructions as good as I could, you would sympathise in my vexation at seeing the most important part converted into sheer nonsense.

I trust to your kindness in not letting a single copy go forth without the correction being made legibly & conspicuously.² I do not know what the law may be, but I think in justice M^ss Clowes & & Co³ ought to reprint the two sheets; if the work was mine own, I would on no account whatever let a copy go forth in such a state.—

Will you be so very kind as to send me one line to say what you think of the affair, & what you intend doing. It is obvious that the Reader coud doing. It is obvious that the Reader could not have looked over the sheet when set up from the slips.

I am truly sorry to give you this much trouble.

Yours very faithfully | C. Darwin

Pray tell me have many copies been distributed?
