Summary

Encloses letter [from A. R. Wallace?] about the Reader.

Wants his opinion of a letter from Fritz Müller on climbing plants.

Summary

Transmits letter [from Fritz Müller].

Has been asked to permit a French translation of Orchids and Journal of researches.

At work on sexual selection.

Summary

Has finished Variation. May insert a chapter on man.

Still puzzled by seeds of Adenanthera.

New Zealand and Borneo flora problems continued.

Fritz Müller found six genera of dimorphic plants in one day.

Summary

Replies to JDH on Hallett; doubts that already improved varieties do not vary in other respects.

The North British Review article [see 6841] is worth reading "scientifically"; it made CD feel small.

Awaits JDH’s decision on affinities of Drosophyllum and Drosera.

Is curious to see proportion of males to females in recent census in India.

Summary

Thanks for plant names.

H. C. Watson a renegade about natural selection. Discusses HCW’s views.

F. Müller’s letter enclosed.

Friedrich Hildebrand’s experiments are splendid for Pangenesis [Die Geschlechter-Vertheilung bei den Pflanzen (1867)].

Summary

Has sent JDH’s Genera plantarum to Fritz Müller who finds it useful and offers to supply JDH with Brazilian plants.

Summary

A confounded cock ground the crimson seeds up so CD could not find them in its excrement. CD is puzzled by how seeds can be disseminated if merely ground up by birds. Perhaps like acorns from seeds accidentally dropped by birds?

A woodcock’s leg with dry clay clinging to it, from which CD has grown a microscopical rush.

Spencer would have been wonderful if he had trained himself to observe more.

On New Zealand flora and connection with Australia.

Difficulty of speculating about the amount of organic chemical change at different periods.

Summary

The Acacia must be Belt’s "Bulls’ horns".

The complexity of Utricularia has driven Frank and CD almost mad. Suspects it is necrophagous, i.e., it cannot digest, but absorbs decaying animal matter.

Foster is certainly in error. Every insect that Drosera catches causes aggregation.

Summary

On the Duke of Argyll and a review of his Reign of law.

Asa Gray’s theological view of variation. God’s role in formation of organisms; JDH’s view of Providence.

Insular and continental genera.

Owen on continuity and ideal types

and on bones of Mauritius deer.

On man.

Summary

Thanks for leaves. His notes on them will be of greatest service.

He cannot distinguish some Eucalypti from Acacia. Sends specimens, with numbers, for JDH to name.

Acacia farnesiana branches arrived withered, but saw enough to make him wish to examine the plant.

Has thought of some troublesome experiments for Drosophyllum.

Encloses remarks [missing] by Searles Wood, with which CD disagrees, about a new and strongly marked variety transmitting its characters.

The competition of better adapted forms seems to CD a sufficient explanation [for extinction].

Summary

Returns Charles Naudin’s letter with its case in support of CD’s view of impregnation.

Twits JDH for trying to wriggle out of error made in his lecture and admires his "candour in letting the rat out of the bag". [See 5449 and 5451.]

Summary

Susan Darwin still lives, but is dying.

Requests an Erica massoni to compare with Drosera.

On L. Agassiz’s "astonishing" view that Amazon Valley was filled with gigantic glacier. Asa Gray says LA is determined to cover the globe with glaciers in order to destroy "Darwinian views".

Excellent review of A. Murray [The geographical distribution of mammals] in Gardeners’ Chronicle [(1866): 902].

Frankland’s Royal Institution lecture ["On the source of muscular power" Not. Proc. R. Inst. G. B. 4 (1862–6): 661–85].

Wallace’s paper.

Summary

Describes observations by his son Horace on the extreme sensitivity of twisted seeds to moisture.

Summary

CD has again become interested in "bloom" on plants; requests JDH’s help with seeds and plants.

Summary

JDH too severe on Duke of Argyll.

Pities JDH on [BAAS] address [see 6099]; Huxley feels JDH will do well and will not pity him.

Thinks Huxley will give an excellent and original lecture on geographical distribution of birds.

Has been working hard on sexual selection and correspondence about it.

Mignonette is sterile with its own pollen but any two distinct plants are fertile together. It is utterly mysterious and not even Pangenesis will explain it.

On Lyell’s book [Principles, 10th ed.].

Wallace’s wonderful cleverness, but he is not cautious enough. CD differs from Wallace on birds’ nests and protection.

A. Murray’s miserable criticism of Wallace [J. Travel & Nat. Hist. 1 (1868): 137–45].

Summary

Sends Fritz Müller’s address; has sent him Insular floras [pamphlet].

Summary

Thanks for information about Hedychium. Hopes wings of Sphinx will be found covered with pollen for that will be a fine bit of prophecy from the structure of a flower to special and new means of fertilisation.

Has been at Descent so hard he has done nothing, not even H. Spencer’s answer.

Has not yet read Croll ["Ocean currents", London Edinburgh & Dublin Philos. Mag. 47 (1874): 94–122, 168–90].

Has heard nothing about Carter and Eozoon. Eozoon, he infers, is done for.

Has read Belt [The naturalist in Nicaragua (1874)]: best of all natural history travel books.

Has written to Fritz Müller about leaf-carrying ants.

Hopes to resume work on Drosera.

Summary

An article in North British Review by mathematician against Hooker and Huxley and for William Thomson [P. G. Tait, "Geological time", North Br. Rev. 50 (1869): 406–39]. Feels a conviction that world will be found older than reviewer makes it.

Article on "Design" [by J. B. Mozley] in Quarterly Review [127 (1869): 134–76].

Has JDH studied Drosophyllum?

Summary

Is sending some plants and seeds to JDH.

Thanks Mrs Hooker for telling him of a life of his grandfather [Erasmus Darwin] of which he had not heard.

Summary

Plants received from JDH.

Requests he verify an identification by Fritz Müller.
