Admits that occasional transport is not a well-established hypothesis but believes it more probable than continental extension as an explanation for the stocking of islands.

Will be glad to see JDH at Down.

Pleased by JDH’s success. JDH gives argument for occasional transport with perfect fairness.

W. R. Grove’s address [see 5201] good, but is disappointed that species part was so general.

Darwin states he hopes ARW's paper on sexual modifications and adaptive mimicry in butterflies will be published.

Susan Darwin still lives, but is dying.

Requests an Erica massoni to compare with Drosera.

On L. Agassiz’s "astonishing" view that Amazon Valley was filled with gigantic glacier. Asa Gray says LA is determined to cover the globe with glaciers in order to destroy "Darwinian views".

Excellent review of A. Murray [The geographical distribution of mammals] in Gardeners’ Chronicle [(1866): 902].

Frankland’s Royal Institution lecture ["On the source of muscular power" Not. Proc. R. Inst. G. B. 4 (1862–6): 661–85].

Wallace’s paper.

Did not think JDH had written Murray review [see 5217].

Does not think Gardeners’ Chronicle best for publication of "Insular floras" [Gard. Chron. (1867): 6–7, 27, 50–1, 75–6].

T. Laxton’s article, on direct action of pollen of peas on seed and pod, a grand physiological fact and "delightful" for Pangenesis.

Interview with Herbert Spencer.

Susan Darwin is dead.

Introduces Ernst Haeckel.

Lyell sent same chapters to CD, who thinks them very good but is not convinced that changes of land and water will do all he thinks.

Requests water-lily pods to count, weigh, and to germinate some of the seeds of the crossed and uncrossed pods.

Hopes Haeckel did not bore him.

No summary available.

Requests roots of two species of Mirabilis for "a curious experiment in crossing".

Has subscribed £10 to Jamaica committee to prosecute Governor Eyre.

Will visit Kew on Tuesday [27 Nov].

Is sending some plants and seeds to JDH.

Thanks Mrs Hooker for telling him of a life of his grandfather [Erasmus Darwin] of which he had not heard.

A confounded cock ground the crimson seeds up so CD could not find them in its excrement. CD is puzzled by how seeds can be disseminated if merely ground up by birds. Perhaps like acorns from seeds accidentally dropped by birds?

A woodcock’s leg with dry clay clinging to it, from which CD has grown a microscopical rush.

Spencer would have been wonderful if he had trained himself to observe more.

On New Zealand flora and connection with Australia.

Difficulty of speculating about the amount of organic chemical change at different periods.

Has finished Variation. May insert a chapter on man.

Still puzzled by seeds of Adenanthera.

New Zealand and Borneo flora problems continued.

Fritz Müller found six genera of dimorphic plants in one day.

B. J. Sulivan offers fossil leaves from Eocene beds at Bournemouth to CD or JDH. Does JDH want them, or should they go to Oswald Heer?

Has written to Athenæum [see 5308] about publishers cutting pages of their books.
