Summary

Reception of Scott’s paper.

Difficulty of writing Boott’s obituary.

Critical of Edward Frankland’s glacial theory.

Falconer’s and Ramsay’s views on Himalayan lakes lack support of basic evidence.

Taxonomic distribution of climbing plants.

Huxley picks quarrels with minor figures and thus magnifies them.

Summary

No one believes in Karsten.

Surprised by CD’s observations that illegitimate crosses within a species produce hybrid-like offspring.

JDH’s scepticism of Scott’s observations.

On proposing James Hector vs Julius von Haast for Royal Society; on learned society honours.

Summary

Will arrive at Orpington by usual train.

Summary

On microscopes.

Cannot remember any plants but Melastoma with different coloured polliniferous anthers.

Summary

Has given CD’s name to a species of Abutilon found by Fritz Müller.

Pleased at Henrietta [Darwin]’s engagement.

Summary

Stupefied by CD’s trouble and kindness. All he wanted for Belfast meeting was assurance that mention of published work on Drosera, etc., in Nature, etc., would not interfere with CD’s book.

Would like his Nepenthes results to go to CD or to Royal Society, but prefers CD take them.

Cephalotus very puzzling.

Peas and cabbage grow twice as fast after two days’ immersion in Nepenthes as when placed in distilled water, but four days’ immersion seems to kill them.

Has a splendid Australian Drosera twice as big as D. rotundifolia.

Summary

Thanks CD for his endowment of new Steudel’s Nomenclator [later to become Index Kewensis].

K. White’s gruesome ballad "Gondoline" frightened JDH as a child.

Summary

Will help Romanes. Offers Kew’s facilities for experiments. Is writing to the Board [of Works?] about a physiological laboratory, which Sir Philip Joddrell has offered to build. Thinks Government should support original research like Romanes’.

Summary

The grass [see 6243] is Sporobolus elongatus, common in the tropics.

Visit to Oxford with X Club.

On his forthcoming address.

Summary

Flora of Cameroons shakes JDH’s faith in ability to explain past or present migrations. Sees need for a major novel explanation such as natural selection, glacial cold, or continental connections.

Lyell in a bad way about feud with Falconer.

JDH’s opinion of Wallace, Bates, J. E. Gray, Owen, Asa Gray, Lubbock, and Bentham.

Bentham’s Linnean Society address [see 4118].

Summary

Continued debate on formation of species as a result of retreat from glaciers.

JDH suggests internal powers of species modification, which he knows CD abhors.

Summary

Willy is back from New Zealand. JDH perturbed by what to do with him.

J. W. Dawson’s Bakerian lecture for Royal Society is full of errors, and JDH is forced to recommend that it not be published. [An abstract of the lecture was published: "On the pre-Carboniferous floras of north-eastern America", Proc. R. Soc. Lond. 18 (1869–70): 333–5.]

Summary

Philosophical Club dinner.

Lyell contradicts W. B. Carpenter on current in Straits of Gibraltar.

James Orton’s report on fossil shells found by L. Agassiz 2000 miles up the Amazon. Their identification disposes of the glacial hypothesis.

No news yet from Gladstone on Ayrton affair.

Summary

Kew affairs.

H. J. Carter’s observations are wonderful but want verification.

Skeptical of H. H. Travers’ observations.

Summary

On his reading: George Eliot,

T. F. Jamieson on Scottish glaciation.

Glad Lyell–Lubbock affair is over.

His grief over loss of father and child.

Summary

Would appreciate loan of CD’s chapter on transmigration across tropics, which may help with the difficulties of Australian distribution.

Still regards plant types as older than animal types.

The Cape of Good Hope and Australian temperate floras cannot be connected by the highlands of Abyssinia.

Summary

Praise for Movement in plants, lately arrived.

Praise for Wallace’s Island life

and astonishment that he could be a spiritualist.

Differs with Wallace on age of SW. Australian flora. JDH ascribes its peculiarities to isolation by an inland sea.

Summary

Tyndall, T. A. Hirst and Spencer dissuade him from writing to Mivart, but he will let him feel his disapproval.
