Summary

Thanks WWR for information in answer to his queries concerning expression.

Asks when horns first appear among a breed of sheep on the Guinea coast,

and for information about the gorilla and chimpanzee.

Asks about African ideas of beauty.

Summary

Thanks EW for information [on expression] about Australians.

Summary

Sends his [MS] questionnaire on expression and asks FvM’s help in obtaining answers based on observations of aborigines living in the interior of Australia.

Summary

Grateful for addresses of informants, especially that of Rajah James Brooke.

Dispatch of queries on expression. Answers will make interesting appendix to his "Essay on man" [Descent].

Protective adaptation of female butterflies believed probable.

Believes in sexual selection as applied to man.

Summary

Replies to CD’s queries about expression.

Summary

Survey of species with well-marked varieties: JDH’s Labiatae case a "great blow", but result is very generally consistent.

Summary

Encloses a list of British perennials which seed in New South Wales and explains the source of his information. Lists plants which have become weeds in the country.

Summary

CD not convinced that naturalisation of European plants abroad is strictly dependent on creation by agriculture of disturbed ground.

More than half through his chapter on geographical distribution.

Summary

Relates some observations on expression among Australian aboriginals and encloses answers to CD’s queries from other observers. [These include letters and observations from: J. A. Hagenauer, 28 May 1868; Archibald Grahame Lang, 17 June 1868; H. B. Lane, 24 June 1868; Templeton Bunnett, 25 June 1868; J. Bulmer (1868). (See introduction to Expression.)]

Summary

Forwards answers from Charles Walter to some of CD’s queries about expression.

Summary

Finds CD’s results [of his survey of well-marked varieties from A. P. and Alphonse de Candolle’s Prodromus systematis naturalis regni vegetabilis (1824–73)] "very curious and suggestive". Thinks the Labiatae will present an obstacle to him as it is a very large and distinct order with well-defined species and genera. Would like to see him tackle more volumes of Candolle’s Prodromus, as his case can only be established by evidence from mundane plants. CD should beware of generalising from local species variability. A comparison of C. C. Babington’s and G. Bentham’s [British] Floras [Babington Manual of British botany (1843, 4th ed., 1856); Bentham Handbook of British flora (1858)] would be invaluable. Suggests CD write to Ferdinand Müller and Charles Moore in Australia. Moisture favouring extension of species is important for CD’s view.

Summary

"You are most perfectly welcome to Fragmenta [F. J. H. von Mueller Fragmenta phytographiae Australiae (1858–64)], & I shall be delighted if they are of the slightest use to you."

Summary

Glad to hear Wallace is contender for Gold Medal. Has highest esteem for his extraordinary talents.

Thanks for H. Barkly’s letter from Mauritius.

Glad to see HB takes same view as CD about bones of deer [see 5395].

Objections to continental extension theory.

Progress [on Variation] very slow.

Summary

Thanks WBC for his account of glacial action in Australia. A mundane cooler period would throw a flood of light on geographical distribution. Has sketched a large MS on subject but does not know whether he will live to publish it.

Questions WBC on striated granite boulders.

Asks him to make a botanical experiment on insect fertilisation.

Summary

Hermaphrodite trees are enough to "knock" CD down. Can JDH observe Eucalyptus to see whether pollen and stigma mature at same time?

JDH’s facts showing European plants are more common in southern Australia than in South America are disturbing because they are improbable on CD’s views of migration.

JDH said he would give examples of Australian forms that have migrated north along the mountains of the Malay Archipelago.

Summary

Sends some answers [missing] to CD’s queries on expression.

Summary

At work on abstract.

Continues argument on effectiveness of dispersal. Has doubts about relationship of isolation to highness of Australian flora. Questions about survival of European plants introduced in Australia.

CD receives the Wollaston Medal of the Geological Society.

Summary

[T. Bell Salter’s?] "hybrid" Epilobium a false claim.

Admires Huxley’s response to Falconer [see 1904].

Tristan da Cunha plant list, requested by CD, supports JDH’s position [on continental extension?].

Chilean plants not exceptional.

JDH considers parallels between Australian Alps and European plants strong evidence for multiple creations.

Summary

Lyell, de facto, first to stress importance of geological changes for geographical distribution.

Asa Gray has given CD too much credit for theories of geographical distribution.

Reaction to hostile criticism

and debt to Lyell, Huxley, JDH, and W. B. Carpenter.

Summary

Cannot come to Down; John Smith is unwell.

Will go to Paris again at end of month.

Wallace and F. J. H. von Mueller of Victoria are most likely candidates for Royal Society Gold Medal for biology.

Encloses letter from Henry Barkly.
