Summary

CD is deeply pleased by AG’s article on him in Nature [10 (1874): 79–81].

Is preparing book on "Drosera and Co." for the printers. Reports observations on digestion in Drosera and Pinguicula.

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

Gratified by AG’s praise of "Climbing plants".

Thanks for Specularia seed.

Summary

Variability of naturalised plants.

Distribution of Arctic/alpine plant species.

Limits to the northern range of plants.

Summary

Thanks for a correction. Hopes AG now has all the sheets of Cross and self-fertilisation.

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.

Summary

Sends some sheets [of Cross and self-fertilisation].

Summary

Is sending sheets of Cross and self-fertilisation. He will be curious to see what AG thinks of it, as AG speaks the truth whether or not he approves. Is sick of trying to correct his "horrid bad style".

Summary

AG’s review of Alphonse de Candolle’s paper [Am. J. Sci. 2d ser. 35 (1863): 430–44] is excellent.

Does not AG consider that orchids oppose Oswald Heer’s view that species arise suddenly by monstrosities?

Infers that AG cannot explain the angles of phyllotaxy; has been looking at Carl Nägeli on the subject.

Reports Gaston de Saporta’s belief that natural selection will ultimately triumph in France.

Is working slowly at Variation.

Reports his observations on the imperfect flowers of Viola and Oxalis.

Summary

Asks AG not to send his rare specimens [of Leucosmia].

Is glad of the notice about black pigs.

Has great faith in Jeffries Wyman;

thinks A. R. Wallace founds his speculation on a feeble basis.

Summary

Believes Lythrum is trimorphic. Asks AG for seeds of plants he suspects are polymorphic.

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

Discusses the meaning of C. K. Sprengel’s term "dichogamy". Dichogamous plants are functionally monoecious; Primula is functionally dioecious.

Reports Hermann Crüger’s observations of Cattleya and of bees pollinating Catasetum. Crüger will observe Melastomataceae.

Has built a hothouse.

Fears Amsinckia cannot be dimorphic.

Ill health slows his work on Variation.

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

Is writing his paper on orchids.

Is surprised that AG gets little or no response with Drosera.

Describes the two forms of Primula and asks whether AG knows any analogous cases of dimorphism.

Reports that John Stuart Mill approves of CD’s scientific method.

Discusses American politics.

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

Floral structure of Melastoma. Asks AG to observe position of pistils in lately-opened flowers of different plants.

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

CD’s sons, George and Francis, are to visit the U. S. Can AG supply any letters of introduction?

Summary

Discusses AG’s article ["Dimorphism", Am. J. Sci. 2d ser. 34 (1862): 419–20]. Does not like the terms "dioecio-dimorphism" or "precocious fertilisation". Discusses the separation of sexes in plants; cannot doubt that hermaphroditism is the aboriginal state.

Discusses AG’s observations on orchids and his review of Orchids [Am. J. Sci. 2d ser. 34 (1862): 138–51].
