Rolle has done great service by publishing his book [Ch. Darwin's Lehre von der Entstehung der Arten (1863)].
Down. Bromley. Kent.
Dear &. Respected Sir
On my return home after a long absence I found the first number of your work; & yesterday I received the second number.—I suppose I owe this present to your kindness, & I sincerey thank you. I am, I am, I am sory, to say, a very poor german scholar & have as yet only skinned through the first number & turned ower the pages of the second.
I can see that there will be much to interess me in this second number; For I am now writing on ``Variation and Domestication''.— Will you permit me to say that I regret to see that You do not give many foot-notes with References.
You have conferred much honnour on me, by undertaking the illustration and enlargement of my views. You will do excellent service in my opinion by getting the subject more discussed & understood; for thus alone will the truth be discovered. Many who criticise what I have written do not at all understand the subject.—
A new german edition of the ``Origin'' with a good many additions, translated by the lamented Prof. Bronn just before his death, is either now published or will by published immediately: Also a translation of my small work on ``Orchids''; the last chapter of wich contain some general remarks on species.—
With sincer respect & my best thanks I beg leave to remain | Dear Sir | your obliged servant | Ch. Darwin.
- f1 3770.f1Rolle 1863 was initially issued in four parts; the publication of the first two was announced on 8 September and 27 October 1862, and that of the remaining two parts on 19 January 1863 (Börsenblatt für den Deutschen Buchhandel 29 (1862): 1862, 2258; 30 (1863): 113). CD's annotated copies of all four parts of this work are in the Darwin Pamphlet Collection--CUL. It appears that the first part of the work was forwarded to CD before his return from Bournemouth on 30 September, and that he subsequently lent it to Charles Lyell (see letter to Charles Lyell, 1 October  and n. 2).
- f2 3770.f2In the second part of Rolle 1863 the author discussed several questions pertaining to domesticated plants and animals, including the importance of external influences on producing variation, acclimatisation, crossing, and the origins of domesticated species. CD began work on the section of Variation dealing with `Facts of variation of Plants' on 7 October 1862 (see `Journal' (Correspondence vol. 10, Appendix II)); he cited Rolle's account of the history of peach cultivation in Variation 2: 308.
- f3 3770.f3Rolle 1863 was written at the suggestion of the Frankfurt publisher, Friedrich Emil Suchsland, as a popular exposition of CD's views on the species question. In translation its title reads: `Charles Darwin's theory of the origin of species in the plant and animal kingdoms and its application to the history of creation'. In the foreword to the book (Rolle 1863, p. [ii]), Rolle referred to CD's approval of his efforts as expressed in this letter: `Nicht das geringste des bisherigen Lohnes der Arbeit aber war der briefliche Ausdruk offener Anerkennung des Strebens und Leistens von Herrn Chs. Darwin selbst.' [The greatest compensation for this work, moreover, came from Mr Charles Darwin himself, who in a letter expressed his candid recognition of the endeavour and the result.]
- f4 3770.f4Bronn trans. 1863. Heinrich Georg Bronn, who translated both Origin and Orchids into German, died on 5 July 1862 (see letter from E. Schweizerbart'sche Verlagsbuchhandlung, 11 July 1862).

- f6 3770.f6The copy is in Rolle's hand and includes his errors of transcription; it may have been prepared on behalf of Francis Darwin, who, after his father's death, borrowed letters or copies of letters from many of CD's correspondents, in order to prepare LL and ML (see Martin and Uschmann 1969, p. 70).
