Summary

W. H. Harvey is dead. His loss to science.

Will get a copy of Crawfurd’s paper. It was such trash he tore his up.

His letter to Asa Gray was about his [JDH’s] proof that America will have an aristocracy from interbreeding of wealth, intellect, and beauty; and the lower classes, not having time for politics, will leave them to the aforementioned.

Summary

Thanks AdeC for his memoir ["Étude sur l’espèce", Ann. Sci. Nat. (Bot.) 4th ser. 18 (1862): 59–110].

CD astonished at the amount of variability in the oaks.

CD differs from most contemporaries in thinking that the vast continental extensions of Forbes, Heer, and others are not only advanced without sufficient evidence but are opposed to much weighty evidence.

AdeC’s comment on CD’s work [Origin] is generous.

CD is satisfied at the length AdeC goes with him and is not surprised at his prudent reservations. He remembers how many years it took him to change his old beliefs. The great point is to give up immutability. So long as species are thought immutable there can be no progress in "epiontology" [see ML 1: 234 n.]. CD is sure to be proved wrong in many points but the subject will have "a grand future".

Summary

Has sent the Utricularia with the bladders that CD described.

In Variation CD does not mention a rare breed of Siamese cat, which she owns.

Asks for another photograph.

Summary

Informs CD that he has forwarded some oils and opium.

Summary

Arranges a time for visiting HF.

Summary

Thanks for informative letter of 2 February. CD is glad to have CVN’s opinion on the crossing of varieties of melons,

has made use of his memoir on the Cucurbitaceae ["Cucurbitacées cultivées au Muséum d’Histoire Naturelle en 1862", Ann. Sci. Nat. (Bot.) 18 (1863): 159–208]

and anticipates with great interest his work on hybridisation.

Summary

Praises MS of first chapter of HWB’s book [The naturalist on the river Amazons (1863)]. Suggests he give common names and make comparisons to familiar English species to help readers. Suggests a few changes. Will speak strongly to Murray about publishing whenever HWB is ready.

Summary

Briefly answers GH’s query whether animals can perceive any qualities unperceived by man.

Summary

CD’s pleasure at JDH’s willingness to help Scott find a position in India.

Naudin underrates contamination of his experiments by insects. Thus CD doubts Naudin’s results on rapidity and universality of reversion in hybrids.

Wallace’s paper on man [see 4494] reflects his genius, although CD does not fully agree with it.

Summary

Apologises for the trouble he has caused over his enquiries about strawberries. Describes the problems he and Emma have had with Verbascum.

Summary

Comments on CD’s Lythrum paper [Collected papers 2: 106–31]

and on H. Crüger’s orchid paper [J. Linn. Soc. Lond. (Bot.) 8 (1865): 127–35].

May take position at Calcutta Botanic Garden.

Regrets he cannot be elected to Linnean Society.

Pleased Asa Gray has commented on JS’s paper.

Summary

Will return page on pigeons.

Has concluded his crossing experiments and found no trace of hybrid sterility or loss of fertility.

The Field is publishing a series of papers on different pigeon varieties [24 (1864): 366, 395, 459; 25 (1865): 115, 139, 155, 228, 258].

Summary

Congratulates AG on the "grand news of Richmond".

Still interested in dimorphism and would welcome new cases.

Working on Variation

and correcting proofs of Climbing plants.

Would like seed of AG’s dimorphic Plantago.

Cannot understand how the wind could fertilise reciprocally dimorphic flowers.

Summary

Sends a map of the province of Canterbury, marking his own and other explorations.

Summary

Describes plans for new German edition of Origin [1867].

Summary

Thanks JS for orchid paper [Trans. Bot. Soc. Edinburgh 7 (1863): 543–50]. JS presents excellent new facts on sterility of orchids.

His argument that coloured primroses are not hybrids is good, as is idea of discovering primrose parentage by breeding for colours.

Summary

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

Summary

Gives the results of her observations on Lychnis; lists four different types of flower present and their occurrence.

Summary

Recommends Lyell’s book [Antiquity of man (1863)].

Quotes praise of AG’s pamphlet [see 2938].

Comments on U. S. politics.
