Summary

Last chapter of Orchids opens up a "knotty sort of question about accident or design".

Changes in orchid flowers as they age.

Thinks CD may find trimorphism in Nesaea verticillata.

Summary

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.

Summary

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.

Summary

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

Summary

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.

Summary

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

U. S. politics.

Summary

Is sending first half of orchid book.

Feels he is wrong about Melastoma.

Summary

Gives J. T. Rothrock’s observations on the structure and fertility of the two forms of Houstonia. Mentions his own observations on Rhexia virginica and Gymnadenia tridentata.

Summary

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.

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].

Summary

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".

Summary

Notes and observations on orchids.

Summary

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".
