Summary

Ernst Haeckel writes that young German scientists are enthusiastic for natural selection.

Did JDH write the article in Natural History Review on trees not producing flowers ["Botanical lesson books", (1864): 355–69]?

Encourages Harvey to publish on his "disagreeable" monster plants.

Summary

On final instalment of "Insular floras" [Gard. Chron. (1867): 75]; rejoices at extent of their agreement.

Some criticisms of JDH’s position on geographical affinities, and volcanic islands.

Summary

CD pleased with Huxley for defending him against Sabine. Also pleased with much of Sabine’s address. Is sure JDH wrote the botanical part.

Suggests James Hector observe which insects visit endemic New Zealand plants

and JDH examine distribution of white vs coloured corollas in New Zealand.

Summary

Thanks for Dawson’s letter. Doubts his evidence that climate of land was not glacial when upheaved after submergence.

Encloses memorandum of questions for C. V. Naudin.

Expression of the emotions.

Is building a hothouse for plant experimenting.

JDH’s ideas on America are more atrocious than his. What a new idea that struggle for existence is necessary to try to purge a government! Probably true. Slavery draws him one way one day, another the next. Yankees are "detestable toward us". Tocqueville.

Summary

Does not know Scott’s qualifications to be curator at Kew.

Frankland’s theory of glaciers is absurd.

Has JDH heard claim that plants in Northern and Southern Hemispheres turn in opposite directions?

Are there plant families with no twining and climbing plants?

Summary

Bad month of sickness. John Chapman’s ice bag on spine.

Does not quite agree with JDH about Lubbock’s plagiarism charges. Lyell’s memory must have failed him.

Summary

Leschenaultia seems very odd. Will try with pollen left on for 48 hours. Illustrates diversity of structures for same purpose.

Bentham’s and Oliver’s good opinion of Orchids is reassuring.

Anxious to experiment on Melastomataceae; thinks it will give important results.

Wants Leschenaultia formosa to try whether viscid outside surface can be fertilised.

Summary

It was foolish of him to say a word about continental extensions so briefly that he thinks JDH misunderstood him.

Summary

Request for plant.

Receipt of Oliver’s letter.

Summary

Agrees with JDH on Lyell–Lubbock controversy except that Lubbock’s printed note does not seem to him insulting. Hopes JDH can heal the breach.

Summary

Clarifies queries on climbing plants.

Summary

Glad to hear Wallace is contender for Gold Medal. Has highest esteem for his extraordinary talents.

Thanks for H. Barkly’s letter from Mauritius.

Glad to see HB takes same view as CD about bones of deer [see 5395].

Objections to continental extension theory.

Progress [on Variation] very slow.

Summary

A German scholar says JDH first applied natural selection to replacement of races of men, the ruder races of Polynesians yielding to civilised Europeans. CD cannot remember reading this.

Warns JDH to take care Welwitschia does not turn into a case of barnacles and consume years instead of months.

In what months do flowers appear in Acropera loddigesia and A. luteola? CD is alarmed by John Scott’s observations on them, which differ from his own. "I am very uneasy."

Summary

Suggests change in sentence of JDH’s "Insular floras" to make meaning clear.

Naudin’s letter about hybrids.

Pangenesis.

Summary

Faraday memorial is an exception.

George [Darwin] has convinced CD that North British Review article is by P. G. Tait [see 6841].

Surprised that leaves of Drosophyllum are always rolled backwards at their tips, but did not know it was unique character.

Summary

JDH should do as he likes with insectivorous plant materials.

He has always thought telling JDH what he has been doing was as good as publishing.

Cephalotus seems as horrid a puzzle as Utricularia.

Nepenthes will turn out a great job if the pitchers of different species act differently. JDH’s paper on Nepenthes [Rep. BAAS 44 (1874): 102–16] is too long for CD’s book. Well deserves a place in Philosophical Transactions.

Summary

JDH’s last letter demolishes woolly alpine plant theory.

Correlation of apetalous flowers and cold climate.

Summary

CD finishing Lythrum paper [Collected papers 2: 106–31].

Pleased at Bates’s appointment

and Wallace’s paper.

Summary

Sends Haast’s report; JDH may use any and all of the details in the letter.

Asks identity of a reviewer of Lyell’s Antiquity of man [Edinburgh Rev. 118 (1863): 254–302].

Summary

On effect of external conditions: CD thinks all variability due to changes in conditions of life because there is more variability under unnatural domestic conditions than under nature, and changed conditions affect the reproductive organs. But why one seedling out of thousands presents some new character transcends the wildest powers of conjecture.

Not shaken by "saltus" – he had examined all cases of normal structure resembling monstrosities which appear per saltum. Has fought his tendency to attribute too much to natural selection; perhaps he has too much conquered it.
