Thanks JDH for his and Huxley’s countering of the false attack on George [Darwin] by Mivart. Encloses a note to Mivart on which he asks JDH’s opinion.

Questions on variation in nature: taxa varying in one region but not another. Variation between vs within species. Rarity of variation in important organs within a species. G. R. Waterhouse’s views on variation in highly developed organs, which CD relates to variation in rudimentary organs.

Asks for cases of obligate self-fertilising plants.

[CD annotation proposes using the Steudel Nomenclator botanicus (1821–4) to determine if variable species occur in genera with many species.]

Representative species may complicate tabulation of varieties.

Questions for Mr Anderson about horse colouring in Norway.

Has been writing an "audacious little discussion" to show that "organic beings are not perfect, only perfect enough to struggle with their competitors".

Hermaphrodite trees are enough to "knock" CD down. Can JDH observe Eucalyptus to see whether pollen and stigma mature at same time?

JDH’s facts showing European plants are more common in southern Australia than in South America are disturbing because they are improbable on CD’s views of migration.

JDH said he would give examples of Australian forms that have migrated north along the mountains of the Malay Archipelago.

Replies at length to JDH’s worried reaction to his comments on lowness of Australian plants. CD distinguishes between "competitive highness", i.e., which fauna would be exterminated and which survive if two faunas were placed in competition, and ordinary "highness" of classification.

Argument, based on geographical distribution and competition, for a mundane glacial period rather than cooling of one longitudinal belt at a time.

Pleased with news of BAAS meeting

and Scott’s possible position as Thomas Anderson’s curator.

Suggests Wallace is due for a Royal Medal.

Agrees with JDH’s criticism of Lyell’s address [see 4614].

Bentham’s Linnean Society address treats continuity of life in a vague non-natural sense.

Rereading his old MS [Natural selection] CD is impressed with work he had already done.

Writing Variation much harder than Climbing plants.

Encloses request to JDH to propose, or suggest on his behalf, that the Ray Society publish a translation of C. F. von Gärtner’s Versuche und Beobachtungen über die Bastarderzeugung im Pflanzenreich (1849).

A son [George Howard Darwin] was born on Wednesday.

Sends queries on Galapagos flora.

Discusses JDH’s comments on [Journal of researches].

CD feels that with his views on descent "really Nat. Hist. becomes a sublimely grand result-giving subject".

"How differently people view the same subject, for I look at insular Floras … as leading to an opposite view to yours."

Mourns death of Lyell. Wonders whether enough men of science were attached to him to raise a fitting testimonial.

Has come to Abinger Hall for a rest after Insectivorous plants, soon to appear. Is sick of the accursed subject.

Rejoices at [Thiselton-Dyer’s] appointment.

Hopes to start looking over his species notes in about a year.

Very much enjoyed Southampton [meeting of BAAS, 9–12 Sept].

Sulivans are coming on Friday. Can JDH come?

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

CD intends writing paper on their propagation.

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

Many thanks for JDH’s beautiful cirripede drawing. Questions on JDH’s observations.

Shares Hooker’s feelings about Douglas Galton and Lord Henry Lennox.

Bored with preparing new editions.

Will be in London tomorrow and will try to pop over to Kew.

Observations on barnacles.

Would like to meet JDH in London.

R. L. Tait has requested CD send his [Tait’s] paper on Nepenthes to Royal Society. CD considers this a nuisance.

Certificate for G. J. Romanes.

Francis’ experiments on mechanism of twisted seeds.
