Summary

Explains several monstrous flowers sent by CD.

Summary

Rejoices that CD is beginning "the book of books", Variation.

Suggests that changes in colour of pollen, stigma, and corolla, as Scott reports in his Primula paper, may be related to changes in the insects required for pollination.

Supports Gärtner translation by Ray Society.

Comments on recent addresses by Lyell [Rep. BAAS 34 (1864): lx–lxxv], Bentham [Proc. Linn. Soc. Lond. 8 (1864): ix–xxiii], and Murchison [Rep. BAAS 34 (1864): 130–6].

Summary

CD has told Scott not to hope for help from JDH.

Health improving.

Hopes to write Lythrum paper soon.

Summary

Sends Living Cirripedia [vol. 2].

Has employed translator for Fritz Müller’s book [Für Darwin (1864)].

Thanks for paper and speech.

Summary

[Outline sketches of pollen from long- and short-styled yellow cowslips and from red cowslip, magnified 350x.]

Summary

Thanks for orchids.

Recovering from nine months’ illness.

Discusses fertilisation of Pulmonaria.

Summary

Argues the antiquity of the human species because natural selection acts differently with respect to men. Changes in man are largely confined to head and brain. Warfare and sex are very uncertain as means of selection.

Gives CD complete credit for theory of natural selection.

Is beginning his narrative of his travels.

Lyell argues against tracing man as far back as Miocene times. R. I. Murchison’s argument that Africa is the oldest existing land implies that Africa is the place to look for early man.

Summary

Has finished correcting Primula paper [see 4332].

Has presented paper on monoecious spikes of maize [Edinburgh New Philos. J. 2d ser. 19 (1864): 213–20].

Summary

J. H. Balfour gives Scott excellent character reference, but says he is unfit either to superintend or be subordinate.

Herbert Spencer’s review of J. M. Schleiden is interesting [see 4457].

Summary

Thanks CD for notes concerning the development of his ideas about the origin of species. Says August Schleicher and Carl Gegenbaur also interested.

Names new supporters of CD’s theory, including Max Schultze, Rudolf Leuckart, and Alexander Braun. Zoologists have been more interested than botanists.

He is writing a general work on the relationships among animals [Generelle Morphologie der Organismen (1866)].

Comments on Fritz Müller’s Für Darwin [1864].

Gegenbaur is revising his Grundzüge der vergleichenden Anatomie [2d ed. (1870)] to accord with evolution.

Thanks CD for copy of book on balanids [Living Cirripedia, vol. 2].

Summary

Spent two days watching Epipactis palustris in a bog. Never saw a moth.

Thinks "Suddenism" and not "Graduality" is the great Law of Nature.

Summary

Remarks on ARW’s review of Samuel Haughton’s paper on bees’ cells

and Origin.

Agassiz’s strength as geologist and weakness in natural history theory.

Work problems.

His butterfly collection.

Problems with book on Malay journey.

Recommends Herbert Spencer and his Social statics.

Spencer’s "masterly" nebular hypothesis.

Summary

W. H. Harvey’s dandelion case worth publishing.

Suspects the uniform Primula elatior JDH referred to is a distinct species.

Scott’s paper on Passiflora shows variability of reproductive systems.

Summary

Sends, for identification, specimens of bees and wasps which fertilise orchids. [Notes in FS’s hand on the same sheet identify the specimens.]

Summary

Thanks for information on Tecoma.

Cannot believe DO’s statement about Catasetum; is sure C. tridentatum sets seeds in its native country.

CD erred on Acropera, but how is it naturally fertilised?

Summary

Oxalis plants have arrived safely [see 4347].

CD regrets his mistake about Disa; will correct it.

Thanks RT for his additional facts about Disa.

Is recovering slowly from ten months’ illness.

Asks whether Strelitzia reginae grows in gardens at the Cape. Suspects it must be fertilised by a bird.

Summary

Has forwarded RT’s paper on Bonatea to the Linnean Society [J. Linn. Soc. Lond. (Bot.) 9 (1865): 156–60].

The Oxalis sent by RT flowered but CD has made out only two forms; he thinks there ought to be three, so would welcome more seed.

Summary

Huxley has answered Kölliker in Natural History Review [(1864): 566–80].

CD is correcting two of Scott’s papers; is convinced primrose and cowslip are two good species.

Summary

CD has proved common oxlip to be a hybrid of cowslip and primrose.

Reviewing literature on climbing plants, CD finds he has much new material.

W. H. Harvey claims evidence of saltation in a dandelion.

Summary

Discusses fertilisation of flowers by bees. Thanks JTM for drawings.
