Self-fertilisation in Fumariaceae.
[CD note on bees’ visiting some members of Fumariaceae.]
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.
Species migration since the Pliocene. Effect of the glacial epoch. Present geographical distribution, especially similarities of mountain floras, explained by such migration; mountain summits as remnants of a once continuous flora and fauna.
Cross-fertilisation in Fumariaceae.
Wishes to know whether differences in constitution (such as disease susceptibility) are related to differences in complexion. "Liability to such a disease as yellow fever would answer my question in the best possible way."
Sends copy of Origin for comments.
Does not feel AG’s views of migration after the last glaciation explain distribution in U. S. as well as CD’s view of migration prior to glaciation.
Discusses arrangements for American edition of Variation.
Observations on apparently inherited instinct in a dog.
Would welcome American edition of Origin.
Thanks for AG’s Japan memoir [Mem. Am. Acad. Arts & Sci. 6 (1857–9): 377–452]. Does not think AG’s arguments for a warm post-glacial period are sufficient, but will not be sorry to be proved wrong.
Believes natural selection explains many classes of facts which repeated creation does not.
Writes of some responses to the Origin.
Agassiz denounces Origin as "atheistical";
AG is currently reviewing it [in Am. J. Sci. 2d ser. 29 (1860): 153–84].
Jeffries Wyman praises it, though not a convert.
Opinions on the Origin: AG thinks it masterly; Agassiz considers it very poor.
Comments on AG’s memoir on Japanese plants [see 2599]; relationship of Japanese flora to N. American.
American edition of Origin. AG’s assessment of the book’s weak and strong points. Suggests Jeffries Wyman would be a useful source of facts and hints for CD.
If an American edition of Origin is considered worth while, CD would like AG’s reviews prefixed to it.
Will use all his strength to produce first part of his three-volume big work [Variation].
CD is glad there is to be an American edition of Origin printed from the corrected 2d English edition.
Sends historical preface and corrections for American edition of Origin;
would have liked AG’s review [Am. J. Sci. 2d ser. 29 (1860): 153–84] at the head.
Agrees with AG’s assessment of weak points.
Thinks AG’s review is admirable.
Reactions of others to the Origin.
Arrangements for the American edition of Origin.
Last sheets of AG’s review of Origin have arrived. CD’s comments and criticisms.
Has been ill with pleurisy.
Sends more corrections and additions for American edition of Origin.
Further additions and corrections for American Origin.
Views of Owen, G. H. K. Thwaites, and W. H. Harvey on CD’s theories.
