Summary

Encloses MS of his paper ["On individual sterility of Oncidium", J. Linn. Soc. Lond. (Bot.) 8 (1865): 162–7].

His next will be on Passiflora, Disemma, and Tacsonia [J. Linn. Soc. Lond. (Bot.) 8 (1865): 197–206].

When he receives proofs of his Primula paper he will add CD’s case about equal-styled cowslip.

Summary

JS has now taken post of Curator of the Royal Botanic Garden, Calcutta.

Wishes to vindicate himself of the charge that he pursued his experiments at Edinburgh to the detriment of his work.

Apologises for poor quality of his Verbascum paper, which was written from his notes during the passage to India [J. Asiat. Soc. Bengal 36 (1865) pt 2: 145–74].

Summary

Thanks for CD’s experimental suggestions. Will count seeds of hybrid crosses.

Requests suggestions for Edinburgh Botanical Society expedition to British Columbia.

Summary

Will observe fertilisation of melastomads as CD requests.

Observations on fertilisation by ants.

Detailed observations on sexes in Catasetum, which were made before he received Orchids and which differ from CD’s findings.

Summary

Has drawn all three forms of primroses CD sent "with same result". Has found no pink variety with middle style.

Summary

Discusses recent correspondence in the Athenæum: the disagreement between Lyell and Hugh Falconer and Owen’s remarks on heterogeny [see 4110].

Briefly discusses orchids and some problems in phyllotaxy.

Mentions the political situation and the quarrelsome behaviour of the English.

Summary

Sends Passiflora paper [see 4485].

Sends seeds of peloric Antirrhinum crossed by normal form and sends results of his experiments [table of crosses].

Summary

Thanks for communicating Oncidium sterility paper [see 4485] to Linnean Society.

Surprised that CD’s seedlings of non-dimorphic cowslip breed true.

Surprised also that the red primrose he sent reverts to wild form. He had reasoned from red’s infertility with yellow that it was an established variety. Tries to correlate inheritance of colour and sterility between varieties.

Summary

Dimorphism and cleistogamy in Hottonia.

AG wants new, unambiguous term for what is now referred to as "dimorphism", "dioecio-dimorphism", or "heterostyly"; proposes "heterogone".

Sends an excerpt from Bulletin of Torrey Botanical Club 2 (June 1871) on Hottonia inflata.

Summary

Reviewing C. V. Naudin’s article ["Nouvelles recherches sur l’hybridité dans les végétaux", Ann. Sci. Nat. (Bot.) 4th ser. 19 (1863): 180–203] for Popular Science Review [5 (1866): 304–13]. Requests references.

Proposes to visit Down on Easter weekend.

Summary

He and L. C. Treviranus have repeated many of CD’s orchid observations with the same results. Sends his paper ["Fruchtbildung der Orchideen", Bot. Ztg. 21 (1863): 329–33, 337–45].

Summary

Answers on Begonia.

Snapdragon crossing experiments.

Thanks for offer of plants.

Summary

Discusses several subjects, including examples of "Unity of coloration",

the origin of gall-producing poison,

Wagner’s theory of viviparous larvae,

and stridulation in insects.

Sends a reference supporting CD’s statement in Origin that flies check propagation of horses and cattle.

Summary

Again refuses to help Scott as "unfitted" to make his way in the world. Scott is unwilling to take his part in the "struggle for life", unlike Tyndall, Faraday, Huxley, and Lindley, who established themselves. Scott’s work is not science, but "scientific horticulture".

Summary

Reports on personalities at the Bath meeting of BAAS [Sept 1864].

Summary

Asks how he can identify pollen-tubes.

Has succeeded in impregnating orchids of widely different genera with each other’s pollinia. "Is not this something new?"

Offers to exchange Catasetum for other varieties.

Summary

Observations on [length of style and length of filament and stigmas of] Pulmonaria.
