F. J. Pictet [Arch. Sci. Phys. & Nat. n.s. 7 (1860): 231–55] goes further than he himself realises.
Naturalists will resist CD’s views until faith in certain "impassable" barriers between existent species is shaken.
Gives CD an instance of convergence.
CD’s divergent series explains those anomalous plants that hover between what would otherwise be two species in a genus.
Inclined to see conifers as a sub-series of dicotyledons that developed in parallel to monocotyledons, but retained cryptogamic characters.
Mentions H. C. Watson’s view of variations.
Man has destroyed more species than he has created varieties.
Variations are centrifugal because the chances are a million to one that identity of form once lost will return.
In the human race, we find no reversion "that would lead us to confound a man with his ancestors".

Dissection of Leschenaultia convinces CD insect agency necessary for self-fertilisation in this case.
Primroses and cowslips seem universally to occur in two forms. Very curious to see which plants set seed.

Cannot provide plants CD requested.
Has sowed several kinds of lettuce seed near each other and has never observed them to cross naturally [see Cross and self-fertilisation, p. 173 n.].

Does FG know Mansfield Parkyns well enough to submit query to him? [Probably about domestication of Columba guinea in Abyssinia. See Variation 1: 183.]
J. S. Henslow’s defence of CD;
[Thomas?] Thomson’s opposition to Origin.
Orders latest issues of North British Review and Dublin Magazine of Natural History. Also would like an order placed for him for a French translation of F. Unger, Versuch einer Geschichte der Pflanzen-Welt [1852], if such a translation has appeared.
Glad to hear JH feeling better. Enclosing a 'shorter and simpler' explanation of some experiment by Léon Foucault, asking for comments.

Thanks JSH for his defence [see 2794].
He is not hurt for long by what his attackers say. His conclusions were arrived at after long study. He has certainly erred, but not so much as "Sedgwick and Co." think.
Asks JSH to send names of plants that vary greatly in length of pistil.
Instructs JDH on how to pollinate Leschenaultia.
Evidence of Leschenaultia and the dioecious condition of cowslips and Auricula is making necessity of insect pollination "clear and clearer".
