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

CD despairs when men like AG and Lyell consider themselves incapable of judging on change of species by descent.

Is confused over phyllotaxy.

Has been looking at Plantago lanceolata.

Summary

Thanks AG for notes on hollies.

Replies to an argument for design. Feels it monstrous to consider orchids created as they are now seen, since every part reveals modification on modification.

Summary

Huxley and CD fear Chauncey Wright’s review is too general.

Reports the praise for AG’s pamphlet.

J. S. Henslow is dying.

Francis Bowen strikes CD as weak and unobservant; presumes he is a metaphysician, which accounts for his "entire want of common sense".

Does wild Apocynum catch flies in U. S.?

Summary

The pamphlet of AG’s Origin reviews [Natural selection not inconsistent with natural theology (1861)]. CD will bear half the costs of publishing.

Will write to Huxley about Chauncey Wright’s review of Origin.

Summary

Has finished Climbing plants;

resuming work on Variation.

Sends abstract of John Scott’s paper [see 4332].

Has received review of Herbert Spencer but cannot believe AG wrote it unless he has muddled his brains with metaphysics.

Summary

Astonished by Agassiz’s argument; has sent AG’s memorandum to Nature [see 8786].

Is working on cross- and self-fertilising plants and has temporarily stopped work on Drosera.

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

Agassiz is strongly opposed to Origin, but CD thinks K. E. von Baer may come out in support.

Discusses the possibility of favourable monstrosities in the light of Theophilus Parsons’ essay ["On the origin of species", Am. J. Sci. 2d ser. 30 (1860): 1–13].

Summary

Discusses the worsening relations between their two countries and the possibility of war.

Expects Orchids and his Primula paper [Collected papers 2: 45–63] to be out soon.

Thanks AG for some facts on dimorphism.

George Bentham has given him a list of Oxalis and Mentha species that are dimorphic like Primula.

Is in a "thick mud" regarding design in nature.

Summary

Thanks for Megarrhiza seeds and information. Has been greatly interested by Megarrhiza germination.

Samuel Butler has attacked CD over Erasmus Darwin.

Summary

Fears England and U. S. will drift into war; he and AG must "keep to Science".

Thanks for facts on Incas; regrets he has always avoided the case of man.

Has sent his Linum paper [Collected papers 2: 93–105].

Is it true that Ohio has legislated against marriage of cousins?

Can AG explain the invariable angles in phyllotaxy; are they the consequence of packing in the early bud?

Owen’s comments on heterogeny in the Athenæum [28 Mar 1863] have vexed W. B. Carpenter; CD has replied [Collected papers 2: 78–80].

Hopes AG will observe Gymnadenia; John Scott has been experimenting on its fertilisation.

Gives his observation on pollination of Cypripedium.

Summary

Is slowly writing Lythrum paper [Collected papers 2: 106–31].

Thanks for [Charles?] Wright’s observations on orchids

– could he note what attracts insects to Begonia and Melastoma? H. Crüger, who was going to observe Melastomataceae, has died.

Describes the climbing habits of Bignonia capreolata and Eccremocarpus scaber.

How does AG know the perfect flowers of Voandzeia are quite sterile?

He has a case of dimorphism in holly; asks AG to report on American hollies.

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

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

Summary

Has not worked for six months due to illness.

Has been looking at climbing plants.

Hermann Crüger’s paper shows that CD was right about Catasetum pollination. Crüger’s account of pollination of Coryanthes "beats everything".

Summary

Thanks for AG’s book, How plants behave [see 8363].

Is correcting proofs of Expression.

Summary

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.

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

AG’s article on climbing plants [Am. J. Sci. 2d ser. 40 (1865): 273–82] is admirable and complimentary.

Reports Fritz Müller’s observations on climbers.

Experiments on dimorphism with Mitchella and Pulmonaria.
