Summary

He is not grieved at CD’s omissions of his [JDH’s] work [from Origin, 4th ed.]. It proves nothing – claims only to be illustration of using CD’s methods.

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

JDH sends a list of the principal confirmatory evidences of CD’s theory which he has prepared at W. R. Grove’s request for Nottingham speech ["Presidential address", Rep. BAAS 26 (1866): liii–lxxxi].

Summary

W. H. Harvey is dead. His loss to science.

Will get a copy of Crawfurd’s paper. It was such trash he tore his up.

His letter to Asa Gray was about his [JDH’s] proof that America will have an aristocracy from interbreeding of wealth, intellect, and beauty; and the lower classes, not having time for politics, will leave them to the aforementioned.

Summary

Refers to enclosure from Asa Gray

with whom he can talk calmly now that war is over. North had no right to resort to bloodshed.

Startled by CD’s attendance at Royal Society soirée.

Has asked E. B. Tylor to make up questions for consuls and missionaries, through whose wives a lot of most curious information [for Descent?] could be obtained.

Tying umbilical cord has always been a mystery to JDH.

John Crawfurd’s paper on cultivated plants is shocking twaddle ["On the migration of cultivated plants in reference to ethnology", J. Bot. Br. & Foreign 4 (1866): 317–32].

R. T. Lowe back from Madeira.

Summary

Has found Verlot.

His sister [Emily Catherine Langton] is dying [d. 2 Feb 1866].

His stomach still very bad. Writes one or two hours and reads a little.

JDH is a wretch to remind CD of his coal-plant prophecy.

Glad JDH will give Nottingham lecture.

Summary

Will do justice to CD’s objections to continental extension theory.

CD misunderstood his question about Isthmus.

Responds to CD’s other points about Madeira and the Azores.

Summary

Extensive discussion of Pangenesis in reply to JDH’s comments.

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

In despair: has lost his copy of Verlot’s memoir on variations of flowers [Sur la production et la fixation des variétés (1866)]. Has JDH borrowed it?

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

Comments on JDH’s list – very good, but Orchids and Primula paper have too indirect a bearing to be worth mentioning. The Eozoon is a very important fact and to a much lesser degree the Archaeopteryx. Müller’s Für Darwin [1864] perhaps the most important contribution.

CD has forgotten to mention Bates on variation and JDH’s Arctic paper ["Distribution of Arctic plants", Trans. Linn. Soc. Lond. 23 (1862): 251–348] in new edition of Origin.

Now finds that Owen claims to be originator of natural selection.

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

BAAS lecture on "Insular floras" [see 5135] went well.

Summary

Is in a mess with his correspondence and will get no assistance before 1 April.

Has agreed to give an address on the Darwinian theory at Nottingham [meeting of BAAS].

Summary

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

Summary

More on continental extension vs transport [or migration] hypothesis. New questions raised. On Madeira, why were insects and plants changed so much, birds hardly at all?

Erratic boulders of the Azores.

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

Scarlet seed is Adenanthera pavonina. JDH’s suggestion on how disseminated.

On Herbert Spencer, "all oil no bone – a thinking pump", but his paper on sap and wood [Trans. Linn. Soc. Lond. 25 (1866): 405–30] is good science. His refusal to bring a specimen for analysis when confronted by JDH.

Bentham and Martin disagreement.

Speculations on New Zealand flora.

Albert Günther’s paper on fishes on each side of Isthmus of Panama [Proc. Zool. Soc. Lond. (1866): 600–4].

On the quantity (bulk and weight) of organic life [matter].

Summary

Had Busks and Lyells to dinner.

Examines and criticises evidence for CD’s hypothesis that the glacial period was not one of universal cold. Physicists deny its possibility.
