Summary

Sends a list of queries for AG.

Asks whether AG can supply specimens for illustrations [for Descent]. Hopes Mr Ford will do the drawings.

Summary

Cautions FD about fluid in labellum of Coryanthes.

T. H. Farrer is enthusiastic about FD’s papers.

Believes humming-birds fertilise many American flowers.

Mentions his reply to FD’s criticisms ["Pangenesis: Mr Darwin’s reply to Professor Delpino", Sci. Opin. 2 (1869): 426; Collected papers 2: 158–60].

Suggests that FD study fertilisation of Gramineae.

Summary

Replies to CD’s questions. Advice on use of term "morphology". Is much struck by CD’s idea that uniformity of an organ throughout a group implies functional inutility; the paradox of this position for classification.

Summary

Glad BDW has proved his case on dimorphism of Cynips.

Interested in galls

and BDW’s Cicada articles [Proc. Entomol. Soc. Philadelphia (1864)].

Summary

Observations on fertilisation of Lapageria rosea by E. G. Henderson, florist of St John’s Wood.

Summary

Comments on Hermann Crüger’s paper, sent by CD, on fertilisation of orchids [J. Linn. Soc. Lond. (Bot.) 8 (1865): 127–35].

Observations on dichogamy in grasses (wheat, rye, barley).

Has not yet read CD’s reply to his article on Pangenesis [Collected papers 2: 158–60].

Summary

Lyell says CD is revising what he says about the Weald in the Origin. Asks CD to look at his subaerial denudation views in his book [Physical geology and geography of Great Britain, 2d ed. (1864)].

Summary

Replies to CD’s queries on sexual habits and differences in fish and lizards.

Summary

Thanks GM for offer of observations. Would be interested to know when the horns of merino rams first appear,

and has long wished for living specimens of Drosophyllum.

Summary

Thanks CD for assistance concerning sponge specimens. Mentions Englishmen who have sent specimens. J. S. Bowerbank has not answered requests.

Sends articles dealing with sponges and Medusae. Cites passages for CD to read. Suggests passages from Entwicklungsgeschichte der Siphonophoren [1869].

Describes meeting with Sars and his trip to Norway.

Summary

Numerical proportion of males to females in greyhound puppies.

Summary

Returns a book on beavers borrowed from CD.

Summary

Thanks for Die Abhängigkeit der Pflanzengestalt von Klima und Boden (Kerner 1869).

Summary

Sends CD a paper ["Ant-agency in plant structure", published in Spruce Notes of a botanist on the Amazon and Andes, ed. A. R. Wallace (1908)] on plant structures he believes are the work of insects; asks him to forward it to the Linnean Society [read 15 Apr 1869].

Writes of his support for the Origin, before which he had been much concerned by the delimitation of so-called species.

Summary

Thanks for CD’s ["Fertilization of orchids", Collected papers 2: 138–56].

Although Thomas Meehan’s paper ["Variations in Epigaea repens", Proc. Philadelphia Acad. Nat. Sci. (1868): 153–6] shows great variability in this genus, JTM sees a need to qualify the generalisation that there is as much variation in the wild as under domestication. He knows no evidence for a constant proportion between variability in the wild and under cultivation.

Observations on correlation between leaf size and exposure to sun and shade.

Has evidence for two varieties of Ophrys apifera in England, which live in mutually exclusive colonies.

Summary

Librarian to the Board of Trade proposes a celebration of CD’s 60th birthday by the Vienna Free Press.

Summary

Dedication of Malay Archipelago to CD.

Comments on scientific papers.

Summary

Huxley has shown him the jaws of an Anoplotherium brought from the Gallegos by R. O. Cunningham.

Saw Hallett’s wheat crops at Brighton; results of his selection very striking.

Huxley is assembling his Darwiniana papers for republication.

Has written a crushing reply to Richard Congreve ["The scientific aspects of positivism", Fortn. Rev. n.s. 5 (1869): 653–70] and JDH feels "infantine" beside him.

Comments on Sabine’s being offered and accepting K.C.B.

Summary

Describes how the offer of C.B. was made. He declined a knighthood. Murchison and Lyell are trying to get him made Knight Commander of the Star of India, but he does not think there is a chance. The Duke [of Argyll?] might do it, but does not like JDH’s Darwinism.

Next Presidency of Royal Society discussed: all (Brodie, the X Club botanists, et al.) are agreed on Lyell.

Everyone is disappointed with Nature.

What did CD think of "Huxley’s rhapsody on Goethe’s ditto" [Nature 1 (1869): 9–11]?

Summary

Describes the floral structure and fertilisation of some melastomes;

discusses the direct agency of insects in modifying the structure of flowers.
