Comments on WT's paper on geological time. Unsatisfied with the efficiency of tidal friction in retarding the rotation of the earth. Considers effect of external attraction on a rotating body to relate to momentum.
Sends work proving all elements formed of one substance: "Pantogen". Feels affinity with CD. His work will cause as great a stir. Has already been preached against. Asks CD for a note as a token of his sympathy.
Answers to CD’s queries on expression in natives of Queensland, Australia.
[Forwarded by Edward Wilson to CD.]
Acknowledges GH’s letter and the lecture on "Faith and science".
Cannot form a judgment on his chemical theory, but if GH establishes his case it will be a magnificent discovery.
"Faith and science" contained many ideas new to CD. Hooker, too, has read it with interest.
CD not a good enough botanist to form a judgment of specimen. Does not understand whether CAJ supposes the variety to be a result of hybridism or of the present very hot summer, which CD cannot doubt will have an effect on some British plants in their struggle for life.
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.)]

Enjoyed JDH’s visit.
Mrs Cameron’s photograph of JDH is grand.
Has heard J. V. Carus will be at Norwich. Suggests JDH mention that Origin was translated by two distinguished naturalists, H. G. Bronn and Carus.
FM’s additions for English edition [1869] of Für Darwin.
Dimorphic plants.
Thanks for his article on musical scales. Misses a description of the elements of the simple scale. Comments on various theories.
Hopes to find the article by Terenzio Mamiani della Rovere (Mamiani della Rovere 1868) on his return home.
Thanks LA for information on sexual differences in the coloration of Amazonian fish. CD was anxious to know how the sexes differed because they are unusual in that the male has the largest share in looking after ova and young.
