Discusses his previous criticisms of EH’s Generelle Morphologie. Fears it will make enemies.

Discusses reception of descent theory in England.

Mentions EH’s trip to Canary Islands.

Obliged for case of grafted ash.

Asks about pods of Arabis.

Would like to borrow Maillet [Telliamed (1750)].

Praises Dareste’s work on teratology; is convinced that it will be highly valued.

Is working on Variation; will send a copy when published.

Acknowledges receipt of £159 11s. 2d.

Glad to hear that the cottages are nearly finished.

Thanks for information on sexual differences.

Orchids; self-sterility and difficulty of getting seeds to germinate.

Dimorphism.

It was foolish of him to say a word about continental extensions so briefly that he thinks JDH misunderstood him.

CD has come to think a name better than "Pangenesis" is needed. Asks GHD to get a suggestion from a classics scholar. "Cell-genesis wd be perfect if it cd be put into Greek."

Is much obliged for AG’s two memoirs ["Mémoire sur le reptile découvert par M. Frossard", Nouv. Arch. Mus. Hist. Nat. 3 (1867): 21–40; Bull. Soc. Géol. France 2d ser. 24 (1867): 397–400].

All "inosculating forms" are very interesting to CD.

Agrees with AG on the importance of attempts to affiliate extinct and existing species.

Will send French edition of Variation when published.

Comments on a discussion of humming-birds by the Duke of Argyll [in The reign of law (1867)].

Encloses article by Henry Parker on the Duke’s book [Saturday Rev. 23 (1867): 82–4].

Sends a sheet of proofs. Will hold four others until he hears from VOK, because of expensive postage. Thinks illustrating Russian translation [of Variation] with woodcuts from A. E. Brehm’s work [Illustrirtes Thierleben, 4 vols. (1864–7)] is an excellent idea.

Discusses hybridisation in cowslip and primrose.

Mentions proposed visit.

Discusses the Duke of Argyll’s book [Reign of law (1867)].

Cites his own views on diversity of structure and beauty.

Encloses letter from Wallace. Sexual selection: evidence advanced by Wallace.

Discusses correlation of growth.

Comments on article in the North British Review [by Fleeming Jenkin].

Discusses the evidence from physics on the age of the earth.

[Four pages of the final letter are missing, but the draft is complete.]

Asks THH to think about a better name for "Pangenesis"; suggests "Cytarrogenesis" or "Atomogenesis", but still prefers vaguer "Pangenesis".

CD probably advised omitting mention of experiments suggesting that oxlips, cowslips, and primroses could be produced from the seed of a single plant

Leaves for London tomorrow. Hopes to see JDH there or perhaps at Kew, but doubts the latter. He is not strong and has a good deal to do.

CD is relieved that JWS’s circumstances have improved. He is pleased to accept Supplement to English Botany. He will try to attend Geological Society meeting.

Disappointed at not seeing JDH in London.

Thanks VOK for the present of A. E. Brehm’s Illustrirtes Thierleben [1864–7].

The woodcuts will do admirably [for Variation].

No summary available.

Congratulates EH on approaching marriage.

Sorry he will not visit in autumn.

Glad EH is re-examining Protoamoeba but puzzled to think what he can find.

Describes newspaper account of criticism by Agassiz of Generelle Morphologie.
