Summary

Thanks for abstract of Etna paper [Philos. Trans. R. Soc. Lond. 148 (1858): 703–86]. Never expected to see Élie de Beaumont’s theory ["craters of elevation"] so completely upset. "He must have picked out favourable cases for measurement."

More than satisfied by what was done at Linnean Society [joint reading of CD’s and Wallace’s papers: "Tendency of species to form varieties", Collected papers 2: 3–19]. Intends to prepare longer abstract.

Summary

Is it fair to take advantage of knowing that Wallace is in the field? Seems hard on CD to lose priority of many years, but does not feel this alters justice of case.

Baby [Charles Waring Darwin] has much fever. Frightened because three children in village have died from scarlet fever.

Summary

Everything in Wallace’s sketch also appears in CD’s sketch of 1844. A year ago CD sent a short sketch of his views to Asa Gray. Can CD honourably publish his sketch now that Wallace has sent outline of his views? "I would far rather burn my whole book than that he or any man shd. think that I had behaved in a paltry spirit." Does not believe Wallace originated his views from anything CD wrote to him.

Summary

Encloses MS by A. R. Wallace. CD has been forestalled. " . . . if Wallace had my MS sketch written out in 1842 he could not have made a better short abstract!" Wallace does not say if he wishes CD to publish MS, but CD will offer to send it to journal.

Summary

Comments on letter from Georg Hartung to CL dealing with erratic boulders.

Discusses migration of plants and animals.

A letter from Thomas Thomson on heat endured by temperate plants.

Summary

Communicate papers by CD and A. R. Wallace on "The Laws which affect the Production of Varieties, Races, and Species". Explain that CD and Wallace have, independently and unknown to each other, arrived at the same theory to account for the appearance and perpetuation of specific forms, and that neither has yet published, although CD first sketched his theory in 1839. Give their reasons for arranging the joint presentation.

Summary

JDH wants papers at once. CD sends Wallace’s paper and CD’s abstract of his letter to Asa Gray. Sends [species] sketch of 1844 with JDH’s notes to assure JDH he had read it.

Summary

Asks whether botanists tend to record varieties more carefully in large genera or small genera.

Wants information on the ranges of varieties of a species compared to the range of the species.

Summary

Death of Charles Waring Darwin [1856–8] from scarlet fever.

JDH’s and Lyell’s kindness [presumably about A. R. Wallace’s letter]. CD can provide a copy of his letter to Asa Gray [about CD’s species theory].

Summary

Believes that, in Dicentra, Fumaria and Corydalis, flower structures are related directly to visits from bees. Flower stigmas generally are placed in the path of bees.

Has received paper from Wallace on natural selection; has sent abstract of his notions, with Wallace’s paper, to Linnean Society.

Summary

C. P. Smyth’s observations on geology and natural history of Tenerife are not precise enough to warrant publication in Philosophical Transactions. Suggests CPS draw up an abstract, for the Proceedings, of specific points actually observed, rather than conclusions arrived at on insufficient grounds.

Summary

Hooker has convinced him that move of British Museum by Government is anticipated. He is now willing to sign the memorial. Still fears for library needs, and objects to distant Kensington site. Lyell should be asked to sign.

Summary

Correcting proof for CD–Wallace paper. Has begun abstract.

Large and small genera.

Summary

At work on the introductory essay to Flora Tasmaniae.

Discusses the effects of climate and geography on "vegetable strife".

Summary

Fertilisation of papilionaceous flowers [Collected papers 2: 19–25].

JDH’s reactions to CD’s theory.

Discussed human fossil evidence with Hugh Falconer.

Summary

CD declines to write Lyell éloge [for Copley Medal] because of his ill health.

Summary

Thanks JDH and Lyell for the actions they have taken with respect to ARW’s and CD’s papers. Considers himself fortunate to have been given any merit for his work. Is pleased that his correspondence has led to the earlier publication of CD’s work. It would have caused him "much pain & regret" if CD had made ARW’s paper public unaccompanied by his own views.

Summary

Lyell receives Copley Medal; CD to write notes for JDH’s éloge of Lyell.

Summary

Pleased with JDH’s reaction to MS on large and small genera.

Confident of soundness of principle of divergence.

CD experimenting on pollination mechanism of Leguminosae. Asks JDH to investigate Fumariaceae.

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.
