My dear Sir,

Many thanks for your never-failing kindness. I am always making mistakes. Perhaps I am deceiving myself, but I think I saw the word cleistogene used by some one else & that made me forget the true term. I found out my error some time ago, for I am now writing on cleistogamic flowers.1

These flowers form the subject of a chapter in a small book which I shall send to the printers in about a months time, & which relates chiefly to heterostyled plants. When this book is published I shall have worked up all my old materials on plants, & as far as I can see you will have a long or final rest from the labour of translation.2

Accept my cordial thanks for your kind expressions towards me, & believe me, | Yours very sincerely | Charles Darwin

P.S. | Give my very kind remembrances to Dr Dohrn; I am very glad to hear that you so much enjoy yr work there3

Had found out his error [use of "cleistogenous" for "cleistogamous" in Cross and self-fertilisation] some timeago.

Is now writing on cleistogamic flowers [for Forms of flowers (1877)], and, with it, will have worked up all his old materials on plants. JVC will then have a rest from his labours of translation.
