Returns Kosmos.

Thanks CD for permission to use Fritz Müller’s last letter, which contains new observations.

Offers observations on pollination.

Thanks for Forms of flowers.

Sends Greek translation of CD’s "Sketch of an infant".

Is working for Greek acceptance of Darwinism.

Has been reading Samuel Haughton on geological time ["Notes on physical geology, no. III", Proc. R. Soc. Lond. 26 (1877): 534–46]. It is utter rubbish. Asks whether CD thinks GHD should write a critical note on the subject [see Nature 17 (1878): 509–10].

Asks for subscription for A. H. Everett’s cave explorations in Borneo.

Is sure CD is pleased with Albert Gaudry’s new book [Les enchaînements du monde animal dans les temps géologiques (1878)].

Is using CD’s correspondence with Chauncey Wright in his book on CW [Letters of Chauncey Wright (1878)].

Information on Cyclamen and other plants.

Identification of some plants.

"Bloom".

Happy to subscribe to A. H. Everett’s expedition to the caves of Borneo.

Thanks for WTT-D’s help.

Burying action of seeds.

"Bloom" on ferns.

Has sent GdeS’s drawing to Hooker. He, Oliver, and Thiselton-Dyer have been perplexed by it.

L. Lesquereux’s discoveries in the Cincinnati Lower Silurian beds.

Sends birthday greetings and respects.

AG’s review of Joseph Cook ["Lectures on biology", New Englander 37: 100–13].

Encourages CD to work at heliotropism.

Thinks Thomas Meehan is as "rattle-brained" as Joseph Cook.

[A damaged fragment cut from this letter is pinned to 11051.]

Thanks for letter. CD now has all the seeds and information he requires.

Value and origin of amphicarpic habit.

CD at first thought GHD should not answer Haughton [see 10689], but Hooker thinks if no correction is made Haughton’s error will be quoted for 20 years. CD is now inclined to agree.

Sends CD’s and George’s tithes.

The Permian fossil sent by GdeS has stirred up the Kew botanists. Hooker suggests it was a Ceratopteris.

Sends birthday wishes.

Discusses his work on the Challenger [expedition] Radiolaria.

Thanks him for works by Lazarus Geiger [probably Zur Entwickelungsgeschichte der Menschheit (1871)

and Der Ursprung der Sprache, 2d ed. (1878)].

Thanks JP for congratulations on LL.D. [awarded by Cambridge University].

Comments on Rudolf Virchow’s book [Die Freiheit der Wissenschaft im modernen Staat (1877)].

Thanks for photograph.

Sends birthday greetings.
