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].

Glad CD is sending his Primula paper to Linnean Society.

Sends promised Linum seeds.

Regrets sending his MS missing two pages.

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

J. H. Balfour objected to notion of maize descent from a hermaphrodite.

Reading of JS’s paper on Selaginella hybrid [Edinburgh New Philos. J. 2d ser. 19 (1864): 192–9] deferred until March. Believes it is first example of experimentally produced hybridity in higher cryptogams.

Has left his position at Edinburgh Botanic Garden.

On fertilisation of Gongora.

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

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.

Thanks for CD’s consoling letter. His mind cannot concentrate after losing his position, and he feels "an inward dread of life’s future". Would have been glad to work for CD. Understands why Hooker cannot recommend him.

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.

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.

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.

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

Sends Passiflora paper [see 4485].

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

Thanks CD for £25. Discusses preparations for trip to India.

Preparations for trip to India. Thanks for testimonial.

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

Asks for additional financial aid for trip to India.

Thanks CD for loan of £10.
