Summary

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.

Summary

Answers JDH’s questions on connection of SE. England and continent,

on the effect of breaking the Isthmus of Panama,

and on Madeira flora as remnant of Tertiary flora.

Cautionary remarks for JDH on his "Insular floras" speech, designed to strengthen case of "occasional migration" theory.

Summary

Thanks for facts about New Zealand flora.

Summary

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.

Summary

His reasons for rejecting Atlantis hypothesis connecting Madeira and Canary Islands.

Summary

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.

Summary

Has heard from B. J. Sulivan about the fossils at Gallegos, Patagonia. Would be a great haul for palaeontology if Duke of Somerset would encourage Capt. Mayne to collect them [on survey of Magellan Strait].

Tells JDH of a new map of world that he might use in his lecture [on "Insular floras", BAAS, 1866, J. Bot. Br. & Foreign 5 (1867): 23–31; Gard. Chron. (1867): 6, 27, 50, 75].

Impressed by H. Spencer’s last number, but each suggestion would require years of work to be of use to science.

Summary

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.

Summary

Thanks for Asa Gray’s letter, enclosed.

Knew JDH would not care about omissions but was vexed at his own forgetfulness.

Summary

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.

Summary

Refers to part of JDH letter on glacial period sent on to Lyell. CD will not yield. Cannot think how JDH attaches so much attention to physicists. Has "come not to care at all for general beliefs without the special facts".

His health is improved but not so good as JDH supposes.

Summary

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.
