Summary

Has sent copy of his paper to Asa Gray.

Melastomad flowers are strikingly neglected by pollinators.

Murray has ordered many illustrations for HWB’s Naturalist on the river Amazons.

Summary

Congratulations on marriage, which CD considers the best and only chance for happiness in this world.

Glad HWB is near completion of book.

Begs him to thank Wallace for Melastoma information; CD "cannot endure being beaten by a beggarly flower".

Summary

CD has questions related to colour differences in the sexes of butterflies, especially in relation to HWB’s paper ["On variation in sexes of Argynnis diana", Proc. Entomol. Soc. Philadelphia 4 (1865): 204–7].

Mentions that his MS on Lepidoptera [for Descent] is longer than he intended and the information is four-fifths owed to HWB.

Summary

CD relates Asa Gray’s pleasure over HWB’s paper and Gray’s plans to write abstract [Am. J. Sci. 2d ser. 36 (1863): 285–90].

Summary

Requests information on the standard of beauty of savages and on whether the female has any influence in selecting a male.

Summary

Extract from the Honolulu Gazette on the decreasing population of the Sandwich Islands.

Summary

Invites JJW to visit Down. Will try to get A. R. Wallace and H. W. Bates also.

Summary

Wallace noticed that melastomads in Malay archipelago were visited by small Hymenoptera.

Darwinism discussed at the last meeting of the Zoological Society. The Darwinians had the best of it.

HWB has committed the "folly" of marriage [to Sarah Ann Mason, 15 Jan 1863].

Printing of vol. 1 [of Naturalist on the river Amazons] is nearly finished.

Summary

In addition to the drawing of a caterpillar which CD intends to use,

HWB sends information on differences of colour and pattern between the sexes of species of Papilio.

Argynnis diana and A. sagana have females that are brightly coloured, but these may be cases of protective mimicry.

Summary

Discusses the Duke of Argyll’s article on the supernatural [Edinburgh Rev. 116 (1862): 378–97].

Has heard that the Incas married their sisters; this may be worth investigating as a case of inbreeding.

Summary

Comments on his own review of Bates’s butterfly paper [Collected papers 2: 87–92].

Thanks AG for information on Platanthera.

Has been wasting more time with Melastomataceae; can find no nectar in Monochaetum; is there any in Rhexia?

Hopes Lincoln’s "fiat against Slavery" will have some effect.

Summary

Discusses the meaning of C. K. Sprengel’s term "dichogamy". Dichogamous plants are functionally monoecious; Primula is functionally dioecious.

Reports Hermann Crüger’s observations of Cattleya and of bees pollinating Catasetum. Crüger will observe Melastomataceae.

Has built a hothouse.

Fears Amsinckia cannot be dimorphic.

Ill health slows his work on Variation.

Summary

Has written to A. J. Gower.

Sends more copies of Queries about expression.

Pall Mall Gazette article [see 6342] is monstrous to say religion did not attack science. Should scientific men ignore whole subject of religion?

Sends French journal with article on JDH and one (weak) by Agassiz on geographical distribution.

M. J. Berkeley has sent his address [Rep. BAAS 38 (1868): 83–7].

CD differs with JDH on Owen; could hardly bear to shake hands with him.

Wallaces, Blyth, Jenner Weirs are coming to stay on Sunday.

Summary

About Francis Darwin’s application for election to [Royal] Society.

Summary

Sends his paper on "Willow-galls" [Proc. Entomol. Soc. Philadelphia 3 (1864): 543–644].

Lengthy criticism of Agassiz’s views on species as stated in his Essay on classification [1857].

Interested by CD’s trimorphism in Lythrum. Thinks some great mystery may lie in the fact that in some genera, some species are tri-, some di-, and some monomorphic, and in other genera, Apis, Vespa, Bombus, all the known species are dimorphic.

Summary

Asks about insect fertilisation of Melastomataceae.

Summary

Discusses the mimicry of the Volucella flies, and the bees and wasps they mimic. Compares it with the different object of mimicry in butterflies.

Refers to incompleteness of Cuthbert Collingwood’s paper [? "On homophormism, or organic representative forms", Proc. Liverpool Lit. & Philos. Soc. 14 (1860): 181–216].

Thanks CD for help in selecting a publisher for his book [The naturalist on the river Amazons (1863)].

He is pleased with his post [Asst. Sec. of Royal Geographical Society].

Summary

Recommends publisher for HWB; admires J. van Voorst but suggests Murray.

In reply to HWB’s letter [missing], comments on neuters and mimicry.
