Summary

Thinks JDH is a bit hard on Asa Gray.

Bates’s letter is that of a true thinker. Asks to see JDH’s to Bates. Point raised in it is most difficult. "There is one clear line of distinction; – when many parts of structure as in woodpecker show distinct adaptation to external bodies, it is preposterous to attribute them to effect of climate etc. – but when a single point, alone, as a hooked seed, it is conceivable that it may thus have arisen." His study of orchids shows nearly all parts of the flower co-adapted for fertilisation by insects and therefore the result of natural selection. Mormodes ignea "is a prodigy of adaptation".

Summary

Sends Passiflora paper [see 4485].

Sends seeds of peloric Antirrhinum crossed by normal form and sends results of his experiments [table of crosses].

Summary

Observations for CD on oxlips, which she finds never grow near cowslips or primroses.

Summary

Thanks for interesting letter on climbing plants.

FM’s view on Anelasma seems probable.

Difficulty quoted by FM from A. Agassiz on embryology of Echinodermata is quite beyond CD.

Summary

Reports on a séance. "The Lord have mercy on us all if we have to believe in such rubbish."

Asks JDH to vote for his nephew, Henry Parker, for Athenaeum membership.

Summary

Informs CD that he has forwarded some oils and opium.

Summary

W. H. Harvey’s dandelion case worth publishing.

Suspects the uniform Primula elatior JDH referred to is a distinct species.

Scott’s paper on Passiflora shows variability of reproductive systems.

Summary

Reports on personalities at the Bath meeting of BAAS [Sept 1864].

Summary

Is preparing a paper on the umbilical cord ["On the anatomy of the umbilical cord", Proc. R. Soc. Lond. 23 (1875): 498–501; 24 (1876): 417–40] of which he sends a preliminary note [missing]. Believes spiral growth of the umbilical cord is important evidence of the descent of man; speculates on spiral growth in general.

Summary

Summary

Discusses dimorphism in flowers. Describes his experiments.

Summary

Sends CD a German pamphlet, "War Goethe ein Darwinianer?"

Summary

CD’s photograph looks like J. R. Herbert’s Moses in the fresco in the House of Lords.

JDH is delighted about oxlip, but hybridity does not explain some large patches that are uniform and do not vary towards either cowslip or primrose.

Encloses letter from W. H. Harvey discussing Myosotis sylvatica and the common dandelion.

Summary

CD does not think he could be wrong about the stigma of Bolbophyllum.

Will not write up Drosera for years.

Praises JS’s experiments. Invites him to send a paper to Linnean Society.

L. C. Treviranus says all species of Primula present two forms except P. longiflora.

Summary

Comments on his Primula paper [see 4213].

Describes his situation in Calcutta.

Summary

Sends copy of his second paper on mutability of race forms ["On the mutability of species", Proceedings of the Northern Entomological Society, 22 December 1862, pp.4–26].

On tactics of his opponents.

He and Bates have divided up Carabidae and Vanessa for studying relationship of forms.

Summary

Thanks CD for influence used with Hooker to obtain a colonial position. Has offended J. H. Balfour by refusing the Darjeeling post and James McNab has become unfriendly, although his experiments do not detract from his garden work.

Will write Primula paper for Linnean Society as CD suggests.

His Darwinism is unpalatable at Edinburgh Botanic Garden.

Describes results with non-dimorphic Primula species. Such cases do not accord with CD’s view that characters are slowly acquired.

Thanks for criticism of his writing style.

Will try to raise Acropera from seed (never done before in Britain) to examine its sexual forms.
