Orchids.

Lyell has written to JDH about coal-plants of Melville Island.

Has glanced at first edition of Principles and has no doubt that Lyell meant the whole globe was cooler when land was massed at poles. JDH doubts this.

Asks to visit Down on Saturday.

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.

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.

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].

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.

Suggests a memorial from Huxley, Murchison, and other geologists on the Gallegos fossils. He will speak privately to Duke of Somerset.

Working on "Insular floras" lecture for BAAS Nottingham meeting [see 5135].

Puzzled at distribution of Madeiran and Canaries plants and insects.

Supports Forbes’s Atlantis hypothesis [see 956], which he has reread and to which he will allude.

Wollaston disappointing on Madeiran insects.

Questions for his lecture on "Insular floras".

Comments on CD’s criticism of Atlantis. Has no fixed opinion on continental extensions. Great objections to hypotheses of CD and Forbes: botanical to CD’s; geological to Forbes’s. Will point out that natural selection is necessary to both hypotheses.

Alexander Beatson mentions a bird in considerable numbers on St Helena which appears to contradict CD’s statement in Journal of researches that only introduced land birds exist there.

The Azores flora and fauna tell heavily against Atlantis joining them with America and against transoceanic migration from America.

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.

Is attempting to sum up the two theories impartially and must raise all the difficulties with each. More on his differences with CD.

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.

Hopes to arrive with MS of "Insular floras" on Saturday.

Returns two volumes of Felix Holt [George Eliot (1866)]

and the Coddington [lens].

John Smith will send Drosera.

Nation reports that Louis Agassiz holds that the Amazon Valley was formed since the glacial epoch.

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

On his "Insular floras" lecture.

Huxley’s success as President of Section.

D. W. R. Grove’s address. Grove left Darwinism to JDH after "sounding the charge".

[N. C.?] Seringe’s article [unspecified] has come safely.

Feels deeply at CD’s distress [Susan Darwin is dying].

Drosera will go in a day or two.

Drosera and Erica massoni have been sent.

Had heard of Agassiz’s theory but not that CD’s theory had raised it.

JDH wrote the article on A. Murray.

Frankland’s lecture too much for him.

Lyell has sent chapters [of 10th ed. of Principles] to JDH, who objects to CL’s ignoring the part vapour plays in affecting temperature of the globe.

Parliament will be asked to buy W. J. Hooker’s collection.
