Summary

Thanks for information about Hedychium. Hopes wings of Sphinx will be found covered with pollen for that will be a fine bit of prophecy from the structure of a flower to special and new means of fertilisation.

Has been at Descent so hard he has done nothing, not even H. Spencer’s answer.

Has not yet read Croll ["Ocean currents", London Edinburgh & Dublin Philos. Mag. 47 (1874): 94–122, 168–90].

Has heard nothing about Carter and Eozoon. Eozoon, he infers, is done for.

Has read Belt [The naturalist in Nicaragua (1874)]: best of all natural history travel books.

Has written to Fritz Müller about leaf-carrying ants.

Hopes to resume work on Drosera.

Summary

Rejoices over baby’s improvement.

Horace Darwin has intermittent fever.

Thanks JDH for page of the Farmer, a great service.

R. Trail’s potato grafting case would be of extreme value for demonstrating Pangenesis. [See Variation 1: 395.]

Summary

Drosophyllum arrived; none of his observations turned out as he expected, but nevertheless he understands its habits better than he did. The secreting hairs that he observed may be explained as a mere chemical reaction.

Comments on various articles he has read.

Asks for Thiselton-Dyer’s notes.

Summary

Asks JDH to arrange for some melastomads to be sent to him.

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.

Summary

Wants some seeds to see how certain seedlings break through ground.

Summary

Heartily glad about Willy.

Has never had Zizania.

Still has Leersia. He cannot make the beast produce.

What slow coaches the Ministers are about the Ayrton affair.

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

Pleased at success of JDH’s address. Has read several press reports.

Spectator pitches into JDH about theology ["Dr Hooker on the evidences", 22 Aug 1868, pp. 986–7].

Feels JDH has "immensely advanced the belief in evolution of species".

Summary

CD continues very ill.

His only work is a little on tendrils and climbers. Asks whether all tendrils are modified leaves or whether some are modified stems.

Last number [Jan 1864?] of Natural History Review is best that has appeared.

Summary

Visiting his son Horace.

Studying action of carbonate of ammonia. Finds similar looking Euphorbia root cells react differently.

Intrigued by Dischidia rafflesiana, whose pitchers manufacture manure-water that nourishes adventitious roots. Does JDH know histologist for detailed study?

Julius von Wiesner’s criticism of Movement in plants "vivisects" CD in "a most courteous but awful manner" [Das Bewegungsvermögen der Pflanzen (1881)].

Summary

Concern about futures of Willy [Hooker] and Horace [Darwin].

Henrietta [Darwin] back from Cannes.

CD has been to Cambridge to visit Frank [Darwin]. Saw Sedgwick, who took him to the [Geological] Museum and utterly exhausted him. Humiliating to be "killed by a man of 86".

Saw Alfred Newton.

CD has been working away on man, to much greater length (as usual) than expected,

and on cross- and self-fertilisation.

Does JDH happen to have seeds of Canna warszewiczii matured in some hot country?

Sympathises with JDH on Dawson’s paper – amusing that Dawson hashes up E. D. Cope’s and L. Agassiz’s views.

Summary

Grieved by Falconer’s and Prestwich’s treatment of Lyell.

Reproductive anatomy of the common ash reminds CD of JDH’s Welwitschia because of its transitional forms.

Pleased JDH encourages Oliver to do orchids.

Summary

CD would be pleased to sit for a bust by Thomas Woolner for JDH, but he is too ill now.

Emma’s views on slavery and the Civil War.

Summary

Masdevallia turns out to be nothing wonderful, "I was merely stupid about it."

Asks for plants for experiments.

Hedysarum and Oxalis sensitiva seeds.

Asks whether Oliver knows of experiments on absorption of poisons by roots.

CD finds he cannot publish this year on Lythrum salicaria; he must make 126 additional crosses!

Asks for odd variations of common potato; he wants to grow a few plants of every variety.

Variation is crawling.

Has had some bad attacks lately.

Summary

His bad health continues.

Thirty-two plants have come up from the earth attached to partridge’s foot.

Origin to be published in Italian.

Owen was wrong: Origin will not be forgotten in ten years.

Summary

Sorry to hear of Mrs Hooker’s health and domestic problems. Wishes natural selection had produced neuters who would not flirt or marry.

Will be eager to hear Cameroon results.

Wishes JDH would discuss the "mundane glacial period". Still believes it will be "the turning point of all recent geographical distribution".

Pollen placed for 65 hours on apparent (CD still thinks real) stigma of Leschenaultia has not protruded a vestige of a tube.

"Oliver the omniscient" has produced an article in Botanische Zeitung with accurate account of all CD saw in Viola.

Asa Gray’s "red-hot" praise of Orchids [Am. J. Sci. 2d ser. 34 (1862): 138–51].

Summary

Hildebrand has sent copy of his paper on Pulmonaria in Botanische Zeitung.

How much should CD contribute to Falconer’s bust?

Oswald Heer on alpine and Arctic floras.

A. R. Wallace on geographical distribution in Malay Archipelago.

Lyell’s new edition of Elements. Wishes someone would do a book like it on botany.

Summary

Naudin has not answered CD’s letter.

Reactions of Candolle, Naudin, Decaisne, and Gaston de Saporta to Origin.

CD’s new hothouse.

CD’s Linum paper.

JDH’s work on Welwitschia.

Summary

Describes observations by his son Horace on the extreme sensitivity of twisted seeds to moisture.
