Summary

Encloses his notions [missing] on John Scott’s offer; some points in explanation.

Summary

CD’s encouragement of John Scott, who has found a case of self-incompatibility in orchids, like William Herbert’s in Crinum.

Nägeli on phyllotaxy.

CD’s observations on broom fertilisation.

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

Sends Primula scotica and P. farinosa.

So far cannot fertilise Gongora atropurpurea although it is similar to Acropera luteola.

Experimenting on intergeneric hybrids to test CD’s view that sterility is not a special endowment.

Scott’s personal history.

Acropera capsule grows.

Plans for experiments CD has suggested on Primula, peloric Antirrhinum, and Verbascum.

Asks about Gärtner’s experiments on maize.

Aware of Anderson-Henry’s failures.

Through kindness of J. H. Balfour and James McNab, enjoys facilities for research. JS is in charge of the propagating department. Balfour almost engaged him to be superintendent of the Madras Horticultural Garden.

Summary

Glad CD is sending his Primula paper to Linnean Society.

Sends promised Linum seeds.

Summary

Reports the observations of Hermann Crüger and John Scott that fruit is set by orchids whose flowers never open and that pollen-tubes are emitted from pollen-masses still in their proper position. These cases convince CD that in Orchids he underestimated the power of tropical orchids to produce seed without insect aid but he is not shaken in his belief that the structure of the flowers is mainly related to insect agency.

Summary

Plants, safely arrived from Kew, fill new greenhouse.

Summary

Seeks advice for John Scott on job offer in India.

Summary

Thanks for paper on Linum [Collected papers 2: 93–105].

One of his gardeners [John Scott] is also studying such fertilisation and appreciates CD’s encouragement; Scott has paper to read for Edinburgh Botanical Society.

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

Comments on his own review of Bates’s butterfly paper [Collected papers 2: 87–92].

Thanks AG for information on Platanthera.

Has been wasting more time with Melastomataceae; can find no nectar in Monochaetum; is there any in Rhexia?

Hopes Lincoln’s "fiat against Slavery" will have some effect.

Summary

Comments on his Primula paper [see 4213].

Describes his situation in Calcutta.

Summary

CD’s opinion of Lyell’s Antiquity of man.

Geographical distribution during and between glacial periods.

Latent characters and reversion.

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

Observation on morphology of Primula ovarium sent for DO’s use.

Summary

Is glad MTM is going to experiment on Passiflora.
