My dear Sir

I shall be right well pleased if you will translate my new book, & sh^d. certainly have communicated with you in due time.¹ I am now going over the m.s for last time, & the whole will be sent to Printers in 2 or 3 weeks.— I grieve to say that it is a big book with nearly 200 woodcuts. The type will be of 2 sizes: the larger for conclusions & the smaller with an account of the observations & experiments.² The work is the result of much labour, that I fear will displease many of your justly renowed physiologists in Germany.³

M^r. Murray inserted the announcement in Nature without my knowledge & used a term which I have had to employ largely in the book, but which is not fitted for the Title.⁴ I enclose Title, as at present seems to me best. The work is an attempt to bring all the diversified movements of Plants under one general law or system. I will send Proofs when ready, but this will not be for some month or two, for I must have a few weeks rest. Of course if you & Herr Koch⁵ sh^d. think the book not worth translating you can draw back.

I hope & believe that it contains a fair amount of new matter.

Believe me my dear Sir, Yours very sincerely | Charles Darwin.
