Summary

Fertilisation of papilionaceous flowers [Collected papers 2: 19–25].

JDH’s reactions to CD’s theory.

Discussed human fossil evidence with Hugh Falconer.

Summary

Floral anatomy.

Wallace’s capital response on reading Origin.

E. W. Binney has published on coal-plants living in marine waters ["On the origin of coal", Mem. Lit. & Philos. Soc. Manchester 2d ser. 8 (1848): 148–94], an old CD idea.

Waste of pollen in horse chestnut will make a good case against perfection.

Summary

Etty [Henrietta Darwin] very ill with diphtheria.

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

"Climbing plants" sent off.

Encourages JDH to include notes on gradation of important characters in Genera plantarum or to write a paper on the subject. Has given prominence to gradation of unimportant characters in climbing plants. Believes that it is common for the same part in an individual plant to be in different states. Same may be true of important parts – for example position of ovule may differ.

Two articles in last Natural History Review interested him; "Colonial floras" [n.s. 5 (1865): 46–63]

and "Sexuality of cryptogams" [n.s. 5 (1865): 64–79].

Fact of similarity of orders in tropics is extremely curious. Thinks it may be connected with glacial destruction.

Leo Lesquereux says he is a convert for the curious reason that CD’s books make birth of Christ and redemption by grace so clear to him!

"Not one question [for JDH] in this letter!"

Summary

Wide-ranging species more "improved" than relics in small areas because they exist in large numbers and thus are subject to intense competition.

His abstract is 330 folio pages long so far.

Summary

Sorry to hear of JDH’s household troubles.

Will try to get a couple of flowers of Leschenaultia to send him.

"What a good case that of the Cameroons"; the 4000ft [elevation] is much to CD’s "private satisfaction".

Sends JDH a copy of Orchids.

Summary

Asa Gray writes as if Civil War were a holy war.

J. E. Renan on Jesus [Vie de Jésus (1863)].

Literature on tendrils of Cucurbita is contradictory.

Summary

CD wishes he could sympathise with Asa Gray’s politics.

Orchids to appear soon.

Pre-glacial Arctic distribution.

Work on floral dimorphism.

High opinion of Buckle as a writer.

Summary

On the variety of species definitions prevalent among naturalists.

Summary

The Lyell–Falconer squabble.

Discusses island vs continental floras and their degree of modification.

Critical of Wallace.

CD’s observations on phyllotaxy.

Summary

Differences between tendrils derived from leaves and those derived from branches.

CD on Asa Gray’s attitude on the Civil War.

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

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

JDH wants papers at once. CD sends Wallace’s paper and CD’s abstract of his letter to Asa Gray. Sends [species] sketch of 1844 with JDH’s notes to assure JDH he had read it.

Summary

Huxley’s capital, witty letter.

Charles Kingsley has written of his interest in "Climbing plants".

Health has been very bad.

Summary

Fertilisation of clover by bees in New Zealand.

Uneasy about biggest genera and their varieties.

H. T. Buckle’s sophistry [History of civilisation in England (1857)].

Working on bees’ cells.

Summary

Death of Charles Waring Darwin [1856–8] from scarlet fever.

JDH’s and Lyell’s kindness [presumably about A. R. Wallace’s letter]. CD can provide a copy of his letter to Asa Gray [about CD’s species theory].

Summary

Refers to part of JDH letter on glacial period sent on to Lyell. CD will not yield. Cannot think how JDH attaches so much attention to physicists. Has "come not to care at all for general beliefs without the special facts".

His health is improved but not so good as JDH supposes.

Summary

CD favours occurrence of reversions, although lack of experiments forces one to vague opinions. Reversions oppose only the inheritance not the occurrence of variation. Discusses relation of reversion, direct influence of conditions, and selection.
