Asks if CD will have corrections for 2d German ed. of Origin.

CD’s theory only natural way to explain creation but contradicts current knowledge about origin of life from inorganic matter.

Has read Primula paper [Collected papers 2: 45–63] with interest.

Pleased that new German edition of Origin is wanted. Wishes to make corrections.

Suggests German translation of Orchids.

Comments on HGB’s book [Untersuchungen (1858)].

CD can add revisions since he cannot begin work on 2d German ed. of Origin until May.

Schweizerbart wants to publish translation of Orchids. Asks for woodcuts for illustrations.

Sends additions and corrections for 2d German ed. of Origin [1862–3].

Before a German translation of Orchids is done, CD thinks HGB should read part of it and decide if it is worth while; CD has doubts.

Thanks for revisions in 2d ed. of Origin. Suggests correction regarding species numbers in the Tertiary.

Comments on pages of Orchids and problems of German translation.

Believes CD’s theory not yet proven, but that it will finally lead to truth.

L. C. Treviranus inclined to translate Orchids, but "unfortunately" HGB has already done it. Book’s discussion of plant sexuality important for zoology as well as botany.

Origin is in press. Attaches a list of "quelques petites difficultées" encountered in his translation.

Encloses answers and corrections [concerning Orchids]. Thanks HGB for translating it.

Sends additional notes.
