Summary

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.

Summary

Comments on AG’s memoir on Japanese plants [see 2599]; relationship of Japanese flora to N. American.

Summary

Would welcome American edition of Origin.

Summary

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.

Summary

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.

Summary

Last sheets of AG’s review of Origin have arrived. CD’s comments and criticisms.

Summary

Has received second part of AG’s Atlantic Monthly article ["Darwin on the origin of species", 6 (1860): 109–16, 229–39], and would like to have it reprinted in England with the first part.

Regrets no reviewer has touched upon embryology, which he feels provides one of his strongest arguments.

Summary

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].

Summary

Further additions and corrections for American Origin.

Views of Owen, G. H. K. Thwaites, and W. H. Harvey on CD’s theories.

Summary

Thinks a new U. S. edition of Origin is needed.

Gives observations on the climbing habits of Bignonia capreolata.

Summary

CD is glad there is to be an American edition of Origin printed from the corrected 2d English edition.

Summary

Gives reference to his observations on tendrils [Proc. Am. Acad. Arts & Sci. 4: 98–9].

Notes cases in which the pollen of the fertilising plant affects the form of the fruit of the fertilised plant, e.g., gourds and maize.

Discusses the Civil War and the attitudes of the English press.

Summary

Discusses the ranges of alpine species in U. S. and considers the possible migration routes of such species from Europe.

Lists those U. S. genera which he considers protean and describes the U. S. character of some genera which are protean in Europe.

Describes how he distinguishes introduced and aboriginal stocks of the same species.

Summary

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.

Summary

Opinions on the Origin: AG thinks it masterly; Agassiz considers it very poor.

Summary

Origin has "stirred up the mud with a vengeance"; AG and three or four others have saved CD from annihilation and are responsible for the attention now given to the subject. Reports events at Oxford BAAS meeting.

New evidence supports AG’s view of a warm post-glacial period.

Discusses his recent orchid observations.

Poses AG a question on design in nature.

Summary

Discusses recent reviews of Origin and has made a note on Owen’s [see 2737].

Has become interested in the floral structures of orchids.

Notes his recent observations on Primula; believes he has found male and female forms.

Summary

O. N. Rood sends two copies of an amusing picture by T. F. Beard, "The young Darwinian" to AG, who forwards one to CD.

Summary

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.

Summary

Greatly praises AG’s discussion of Origin in Proc. Am. Acad. Arts & Sci. [4 (1860): 411–15; 424–6].

Mentions other reviews of Origin; believes the BAAS meeting at Oxford greatly advanced the subject. Has heard his views are gaining ground in Germany.
