Summary

Has finished correcting Primula paper [see 4332].

Has presented paper on monoecious spikes of maize [Edinburgh New Philos. J. 2d ser. 19 (1864): 213–20].

Summary

Surprised at CD’s account of Bryanthus.

H. Crüger’s approach to Gongora fertilisation is beset with difficulties.

Reports his work on self-sterility of Oncidium.

Summary

Glad CD is sending his Primula paper to Linnean Society.

Sends promised Linum seeds.

Summary

Discusses the negative testimonial provided him by James McNab.

Sends testimonial from J. H. Balfour.

Would be glad if offered the sort of colonial opportunity Hooker suggests.

Summary

On fertilisation of Gongora.

His work on peloric Antirrhinum, Passiflora, and Verbascum, done at CD’s suggestion, is at CD’s disposal.

Summary

Discusses cost of trip to India and CD’s offer to advance sum. Thanks Hooker for assistance. Would prize a scientific testimonial from CD.

Summary

[Outline sketches of pollen from long- and short-styled yellow cowslips and from red cowslip, magnified 350x.]

Summary

Preparations for trip to India. Thanks for testimonial.

Surprised by the self-fertility of CD’s peloric Antirrhinum.

Summary

Replies to queries on climbing plants.

JDH meets Scott and finds him an intelligent and superior-looking man. Scott wishes to come to Down before leaving England.

Summary

Sends his MS of orchid paper ["A few notes on the fecundation of orchids and their morphology", J. Linn. Soc. Lond. (Bot.) 8 (1865): 127–35] for CD to send to an editor.

CD was right about Catasetum sexes.

Ficus experiments fail.

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

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

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

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.
