Discusses revisions for Variation, 2d ed.

Discusses experiments involving graft-hybrids.

Alludes to Pangenesis.

Sulivans are coming on Friday. Can JDH come?

Describes difficulty of conditions for the experiment with Drosera suggested by THF.

Acknowledges with thanks "Mr Fitzgerald’s magnificent work" [R. D. Fitzgerald’s Australian orchids, part 1 (1875)]. [See 10069.]

JJW is to think no more about mistake [regarding Cytisus graft].

Thanks RDF for a part of his book [Australian orchids, vol. 1 (1875–82)]; suggests further observations RDF could make and defends some of his own conclusions.

Can JDH bring a good book on Corallina or Nullipora of Lamarck?

CD intends writing paper on their propagation.

Thanks for JSBS’s essays; wishes he had said something on Lister’s observations. Speculates on the fungoid nature of smallpox and why there is seldom re-infection.

Discusses digestion by Drosera, the action of its secretion being the same as that of gastric juice.

Thanks AWB for review in Nature [probably review of Insectivorous plants, 12 (1875): 206–9, 228–31].

Asks about FH’s research on maize. Suggests experiments.

Thanks for KLR’s latest work (Rütimeyer 1875).

Comments on GJR’s experiments.

Is obliged to be given a second and improved edition of GKMvS’s excellent lectures.

Thanks ACR for paper and comments on it ["On the denudation of South Wales", Mem. Geol. Surv. G. B. 1 (1846): 297–335].

Sends copy of South America.

Discusses action of the sea.

Criticises ACR’s views on sudden elevation of mountain chains.

CD returns MS of a paper by RLT. "If you have succeeded in separating the ferment, the fact is manifestly important." Asks whether RLT tested the digestive ability of fluid from pitchers without animal matter. This would be necessary to prove that there was ferment in the fluid. CD is glad to hear about the [passage?] for guiding insects; he had guessed this to be the case.

Acknowledges his election to the Akademie.

Would be obliged for correction of references in Variation [1st ed.].

Glad to hear that ARW is so busy.

CD believes that he has thrown some light on the acquirement of the power of digestion in Droseraceae [in Insectivorous plants].

Solicits JDH and others at Kew for signatures to nomination of Francis Darwin for membership of Linnean Society.

Apologises that he cannot supply any maize seed.
