U. S. politics and relations with England.

Wants examples of dimorphism similar to Primula.

Structure and function of Spiranthes flower.

Observations and experiments on Drosera.

CD’s views on design.

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.

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.

Dimorphism: "new cases are tumbling in almost daily".

U. S. politics.

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

Gives some observations on changes in pistil position with age in Monochaetum. Asks whether AG can observe Rhexia for similar movements.

"One of the best men, though at present unknown", H. W. Bates, has taken up natural selection.

Is sending first half of orchid book.

Feels he is wrong about Melastoma.

Thanks AG for praise of Orchids and his notes on several American species of orchid. Comments on AG’s observations.

Is experimenting [on dimorphism] with Rhexia and Melastoma.

Asks AG’s opinion of a paper by Thomas Meehan ["On the uniformity of relative characters between allied species of European and American trees", Proc. Philadelphia Acad. Nat. Sci. (1862): 10–13] which is the best case of the apparently direct action of the conditions of life CD has seen.

Requests postage stamp for his ill son [Leonard].

Thanks AG for observations on Cypripedium and gives recent observations of his own.

Arethusa is very pretty; structure seems like that of Vanilla.

Finds the little (so-called imperfect) flowers of Viola and Oxalis curious: the pollen-grains emit their tubes whilst within the anthers, and they travel in straight lines right to the stigmas.

Sympathises with events in the U. S.

Reports on French translation of Origin by Mlle C. Royer, "one of the cleverest & oddest women in Europe".

Alphonse de Candolle says he wants direct proof of natural selection; "he will have to wait a long time for that".

Thanks for notes on Cypripedium and Platanthera hookeri, which is really beautiful and quite a new case.

His son, George, has been observing the insect fertilisation of orchids.

CD has been crossing peloric flowers of Pelargonium, but doubts he will get good results with respect to sterility of hybrids.

Rhexia glandulosa does not appear to be dimorphic. Lythrum is trimorphic.

Adaptations of orchid flowers. Believes the structure of all irregular flowers is adaptation to insect fertilisation.

Linum grandiflorum distinguishes its own pollen so that when placed on stigma of same flower the pollen-tube is not even exserted.

AG’s orchid observations are admirable.

Owen has lectured on birds’ descending from one form.

French criticism of CD’s Primula paper.

Only AG has seen that Orchids was "a ""flank movement"" on the enemy".

AG’s "capital" review of Orchids [Am. J. Sci. 2d ser. 34 (1862): 138–44].

Thinks there are three forms of Lythrum salicaria.

Discusses transport of seeds by sea.

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

Emma and Leonard have scarlet fever.

Houstonia seems "a grand case"; J. T. Rothrock should publish his observations on the two pollens and the reciprocal action of two hermaphrodites.

Rhexia glandulosa offers nothing odd, but Heterocentron will turn out something marvellous like Lythrum.

Would like to know what AG thinks of last chapter of Orchids.

Glad AG will publish some separate notes on orchids ["Fertilization of orchids through the agency of insects", Am. J. Sci. 2d ser. 34 (1862): 420–9].

Trimorphism in Lythrum.

Bee behaviour.

Lythrum salicaria is coming out clear.

Would be glad of Nesaea seed.

Is disappointed with Melastoma, but is sure there is something curious to be made out.

His experiments with poisons on Drosera lead him to conclude that it possesses something analogous to nervous matter.

Comments on natural hybrids of Verbascum.

Deplores the Civil War and the feelings it has fostered in Britain.

JDH hopes to send Asa Gray copies of GENERA PLANTARUM with the autumn box of 'distributa'. JDH discusses Sir John William Dawson's criticisms of one of his essays concerning plant distribution [possibly JDH's introductory essay from FLORA ANTARCTICA], addressing each point in detail. Dawson's objections centre on the flora of Scandinavia & supposed geological inaccuracies, many concerning Greenland. In the past JDH & Sir Charles Bunbury have quashed some of Dawson's palaeobotany papers sent to the Geological Society. JDH is convinced his own conclusions are sound, they have the support of James Hector & Sir Charles Lyell. Dawson is against Darwinism & the theory of evolution by natural selection. JDH notes that there is currently a lot of changes in geological theory & hypotheses in the discipline are difficult to prove, there is an argument about the effectiveness of current species variation & distribution in determining past land formations. JDH believes geological & biological evidence must both be taken into account to form a strong hypothesis. He makes the point that all facts began as theory, just as absolute specific creation is now questioned so may creation by variation be disproved, or it could become established fact. JDH mentions his own work on Welwitschia [mirabilis], specifically characteristics of ovules in male & female flowers, & Gray's work on Cypripedium. Thanks Gray for Asimina & urges him to write a systematic resume of American flora.

Agrees Max Müller’s book [see 3752] is interesting but cannot see how it will further his "cause".

A book by J. W. Colenso [The Pentateuch and book of Joshua critically examined, pt 1 (1862)] has just appeared and will "make a noise".

Would like some observations made on Cypripedium.

Will not publish yet on Lythrum as he must make many more crosses; the mid-styled is fertile with half of its own stamens.

Would like to try a few experiments on tendrils.

Recommends H. W. Bates’s paper on butterflies of Amazonia ["Insect fauna of the Amazon valley", Trans. Linn. Soc. Lond. 23 (1862): 495–566].

Lyell’s book [Antiquity of man (1863)] is eagerly awaited.

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].
