Thanks CD for the A. Gray review of his paper [see 4022].

Reports his current work is a monograph on Mantidae.

Summary

Working on monstrous Primula. Is ovule anatropous as Asa Gray says, or amphitropous? Does he know natural path of pollen tubes in Primula. Can the tube enter the ovule by the chalaza?

Comments on his view of algal reproduction.

Discusses flower of Cassia.

Sends photograph of himself.

Summary

After finishing vol. 2 [of Naturalist on the river Amazons], CD still has only praise. Remarks that his family is also enjoying the book. He regrets having finished, since he so enjoyed the descriptions.

Summary

His better opinion [of work of Boucher de Perthes].

Explains his position on CL’s treatment of species.

Mentions positive response to his ideas on the part of a German professor [Ernst Haeckel], Alphonse de Candolle, and a botanical palaeontologist [Gaston de Saporta].

Notes negative reaction of entomologists.

Mentions Falconer’s objections [to Antiquity].

Mentions work of Hooker.

Comments on paper by Owen ["On the aye-aye", Rep. BAAS 32 (1862) pt 2: 114–16]

and CD’s review of Bates’s paper [Collected papers 2: 87–92].

Thinks Natural History Review is excellent.

Summary

Provides evidence of self-sterility in Gladiolus.

Has observed three seed-leaves in some Dianthus seedlings.

Cannot cross, or grow from seed, Dielytra spectabilis.

Summary

Lyell is "half-hearted but whole-headed" for CD’s theory. George Bentham wholly converted.

Bates’s book delightful but has a Darwinistic bias.

Cameroon plants.

JDH defends Bates against J. E. Gray’s slanders.

Summary

Fertile flowers of violets, except Viola tricolor, require insect visits.

Summary

Observations on Catasetum.

Figs require insects in order to set seed.

Summary

JDH and Oliver impressed with CD’s observations on gyratory motion of plants.

CD pleased with Bentham’s Linnean Society address on the reception of Darwinism [J. Proc. Linn. Soc. Lond. 7 (1863): xi–xxix].

JDH’s social "dogma": "Brains x Beauty = Breeding + wealth".

[Dated 9 June by JDH.]

Summary

CD too ill to write.

Has evidence of long life of seed transported on a partridge’s foot.

Sends a squib by Samuel Butler on the Origin.

Summary

Discusses dimorphic plants.

Summary

Thanks for CD’s experimental suggestions. Will count seeds of hybrid crosses.

Requests suggestions for Edinburgh Botanical Society expedition to British Columbia.

Summary

JS criticises natural selection as based on an innate "continuously watchful selective principle".

Seeks seed of wild Rocky Mountain maize.

What is CD’s view on origin of maize?

Seeks information on self-sterility of Passiflora and Lobelia.

Weeping habit of trees.

Intended to say bisexual plants presented more established varieties than unisexual, not that they are more variable.

Explains his opinion that homomorphically fertilised Primula will produce only their own form. Is trying homomorphic crosses with different coloured Primula varieties.

Asks to read Asa Gray’s 2d review of Orchids.

Has finally successfully fertilised Gongora, but it was done by unnatural means.

Summary

Studying self-sterility, particularly in Oncidium, where abortion occurs consistently but stigma functions normally. His hybrid orchid crosses show sterility occurs capriciously. Thus it is not a "special endowment".

Disputes Asa Gray’s and Hermann Crüger’s view of rostellar germination.

Doubts absolute sterility of Catasetum.

Disappointed by results with homomorphic cowslips.

Summary

Thanks WED for his botanical specimens and observations.

Discusses Corydalis and the fertilisation of Fumariaceae.

Summary

CD has spoken to Hooker of JS’s scientific merit, but has not suggested him for a colonial appointment.

Advice on style of writing.

Making extensive extract of JS’s orchid paper to communicate to Linnean Society [J. Linn. Soc. Lond. (Bot.) 8 (1865): 162–7].

Summary

Has caught a frog and examined its possibly rudimentary toe. Asks THH if he will dissect it.

Has heard THH is abused in Edinburgh Review and in Anthropological Review [reviews of Man’s place in nature, Edinburgh Rev. 117 (1863): 541–69 and Anthrop. Rev. 1 (1863): 107–17].
