Baby [Charles Waring Darwin] died of scarlet fever on 28 June. "Fear has almost driven away grief."

No summary available.

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.

Death in family [Charles Waring Darwin]. Illness of children forces him to leave home and interrupt work on pigeons.

Darwin thanks Hooker for reporting that all went well at the Linnean Society and supports Hooker's suggestion that he (Hooker) write to ARW to "exonerate" Darwin.

Thanks JDH for his report on the reading of the Wallace and Darwin papers at the Linnean Society [read 1 July 1858; Collected papers 2: 3–19]. Considers how to publish his work. Offers to forward a note from JDH to Wallace.

The crisis is abating – no further scarlet fever in the family.

Darwin comments that Hooker's letter to ARW is perfect and that he has forwarded it to ARW along with one from himself. Darwin states he had resigned himself to giving up priority regarding evolution by natural selection to ARW but for influence from Lyell and Hooker.

JDH’s letter to Wallace perfect. CD’s feelings about priority. Without Lyell’s and JDH’s intervention CD would have given up all claims to Wallace. Now planning 30-page abstract for a journal.

Regards from Isle of Wight.

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.

Darwin requests a clean proof (of his abstract?) for ARW.

After all, CD is now beginning to prepare an abstract of his species theory. Recounts the events leading to joint paper with A. R. Wallace at Linnean Society. Lyell and Hooker urge strongly that he publish a fuller abstract. It is impossible to do justice to subject in an abstract.

His sister, Marianne Parker, has died.

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

Large and small genera.

Six children have died of scarlet fever in Down village.

Writing abstract is amusing and improving work. Thanks JDH and Lyell for setting him to it.

Thanks WJH for an extract on seed transport by sea. [Letter sent with 2314.]
