Acknowledges receipt of £240 7s. 9d.

Hopes to meet JH at Erasmus Alvey Darwin’s house in London on Friday 6 June.

Suspects that bee orchid is self-fertilising form of Ophrys arachnites, which requires insect aid.

Describes floral anatomy of a Catasetum sent by DO.

Has gone on from orchids to studying insect agency in Pelargonium.

His doubts on the worth of publishing Orchids.

Asks whether any correspondents have observed any sensible differences between the bees kept in different parts of Great Britain. CD has heard from several sources that breeds of bee in different areas vary.

Thanks AG for praise of Orchids and his notes on several American species of orchid. Comments on AG’s observations.

Is experimenting [on dimorphism] with Rhexia and Melastoma.

Asks AG’s opinion of a paper by Thomas Meehan ["On the uniformity of relative characters between allied species of European and American trees", Proc. Philadelphia Acad. Nat. Sci. (1862): 10–13] which is the best case of the apparently direct action of the conditions of life CD has seen.

Requests postage stamp for his ill son [Leonard].

Thanks AG for observations on Cypripedium and gives recent observations of his own.

Arethusa is very pretty; structure seems like that of Vanilla.

Finds the little (so-called imperfect) flowers of Viola and Oxalis curious: the pollen-grains emit their tubes whilst within the anthers, and they travel in straight lines right to the stigmas.

Sympathises with events in the U. S.

Reports on French translation of Origin by Mlle C. Royer, "one of the cleverest & oddest women in Europe".

Alphonse de Candolle says he wants direct proof of natural selection; "he will have to wait a long time for that".

Asa Gray approves of Orchids; his work on American species confirms CD’s findings.

Encloses a question [missing] concerning language [from Hensleigh Wedgwood].

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].

Leonard has scarlet fever; CD is sorry WED is unwell.

Sends condolences on death of LH’s wife. Recalls many pleasant hours in Bedford Place. He and Emma thank LH for sending the memorial paper.

It would be a pleasure to see "the first enunciator of the theory of Natural Selection" but his health makes it impossible. Hopes to come to London soon and would like to arrange an interview with PM if he is staying more than a week.

CD orders electrotypes for German edition of Orchids.

Asa Gray doubts an American publication is possible but will review it in Sillimans Journal.

[British] botanists have praised it. Other reviews.

Thanks JHB for specimen of Corallorrhiza;

would like some seeds of Corydalis claviculata.

Refers to his Primula paper [Collected papers 2: 45–63]. Asks GHKT to investigate a similar case in Cinchona.

Is pleased that AdeC is interested in the Primula case ["Dimorphic condition of Primula", Collected papers 2: 45–63]. Is pursuing analogous experiments on other plants and on seedlings raised from the unions.

CD’s "large work" progresses slowly owing to ill health and his work on Orchids.

CD is not surprised that AdeC is unwilling to admit natural selection – "the subject hardly admits of direct proof or evidence. It will be believed in only by those who think that it connects & partly explains several large classes of facts".

Hopes AdeC will publish on Quercus

and rejoices that he intends to return to the study of geographical distribution. No one can claim to have read AdeC’s truly great work on that subject [Géographie botanique (1855)] with more care than CD.

Asks experienced observers whether there are any marked differences between bees kept in different parts of Germany.

Superb, but exaggerated, review [of Orchids, by M. J. Berkeley] in London Review [& wkly J. Polit. 4 (1862): 553–4]. Asa Gray thinks almost as highly. "I have not been a fool, as I thought I was, to publish." The Athenæum review will hinder sales greatly.

It is not certain cuts are wanted by an American publisher [of Orchids].

Has fixed price of £10 for Schweizerbart [Stuttgart publisher].

Testimonial in support of WBT’s application for curatorship of the Hartley Institution.

Asks for information concerning heterostyled and dioecious plants.
