From John Scott 18 February [1863]
Summary
Sends Acropera capsule for CD to dissect.
Will try to raise Acropera from seed (never done before in Britain) to examine its sexual forms.
Studying primroses, parthenogenesis, and reproduction of some cryptogams.

To John Scott 20 [February 1863]
Summary
Thanks JS for the very large Acropera capsule. CD has perhaps made a blunder about the sex of Acropera.
JS was right that successive homomorphic generations of Primula breed true.

From John Scott 3 March 1863
Summary
JS criticises natural selection as based on an innate "continuously watchful selective principle".
Seeks seed of wild Rocky Mountain maize.
What is CD’s view on origin of maize?
Seeks information on self-sterility of Passiflora and Lobelia.
Weeping habit of trees.
Intended to say bisexual plants presented more established varieties than unisexual, not that they are more variable.
Explains his opinion that homomorphically fertilised Primula will produce only their own form. Is trying homomorphic crosses with different coloured Primula varieties.
Asks to read Asa Gray’s 2d review of Orchids.
Has finally successfully fertilised Gongora, but it was done by unnatural means.

To John Scott 6 March 1863
Summary
Answers JS’s criticism of natural selection, which he doubts JS understands. CD does not believe in an "innate selective principle".
To understand "utility" JS should read CD on correlation.
Origin of maize: no longer thinks husked form was wild because of Asa Gray’s evidence on its variability.
Has information from Thomas Rivers on weeping habit in trees.
JS’s experiments on coloured primroses.
Encloses bibliographical note on Passiflora.

From John Scott 21 March [1863]
Summary
Thanks for CD’s answers on Passiflora
and Asa Gray review.
Has observed gradation of sterility in Oncidium species.
Has observed rostellar germination and fertilisation in Laelia. The latter was prevented in Bletia by covering the stigma with plaster of Paris.
Gongora atropurpurea capsules are swelling.

To John Scott 24 March [1863]
Summary
Enthusiastic about JS’s work on Passiflora self-incompatibility.
CD quotes JS on rostellar pollen germination [in "Fertilisation of orchids", Collected papers 2: 77–8]. H. Crüger attributes it to ants’ carrying stigmatic secretion to pollen.
Homomorphic cowslip seedlings are, sadly, showing variation.

From John Scott [1–11] April [1863]
Summary
Studying self-sterility, particularly in Oncidium, where abortion occurs consistently but stigma functions normally. His hybrid orchid crosses show sterility occurs capriciously. Thus it is not a "special endowment".
Disputes Asa Gray’s and Hermann Crüger’s view of rostellar germination.
Doubts absolute sterility of Catasetum.
Disappointed by results with homomorphic cowslips.

To John Scott 12 April [1863]
Summary
Encourages JS to publish on sterility of orchids and to experiment on Passiflora.
Doubted Hooker’s poppy case.
Describes case of primrose with three pistils: when pulled apart allowed pollen to be placed directly on ovules. This supports JS’s explanation of H. Crüger’s case.

From John Scott [after 12] April [1863]
Summary
Thanks for CD’s Linum paper [Collected papers 2: 93–105].
Has not published much because he would be ignored as a gardener; hence he is looking for a foreign appointment.
Has prepared orchid sterility paper at CD’s suggestion [Trans. Bot. Soc. Edinburgh 7 (1863): 543–50].

Summary
Glad to hear of JS’s orchid paper [Trans. Bot. Soc. Edinburgh 7 (1863): 543–50].
Suggests experiments on peloria.

Can send account of Hottonia.

J. H. Balfour has arranged a position for him at a Cinchona nursery. Reluctant to take this position in part because of his experiments for CD.
Asks CD’s advice and solicits his aid in finding a better colonial position. James McNab mistreats him.

To John Scott 31 May [1863]

Thanks JS for abstract of orchid sterility paper from Edinburgh Courant. His case of individual sterility will be of highest use to CD. Criticises JS’s writing. Points out weaknesses in the organisation of his argument and the use of inflated, imprecise language.

From John Scott [3 June 1863]
Summary
Thanks CD for influence used with Hooker to obtain a colonial position. Has offended J. H. Balfour by refusing the Darjeeling post and James McNab has become unfriendly, although his experiments do not detract from his garden work.
Will write Primula paper for Linnean Society as CD suggests.
His Darwinism is unpalatable at Edinburgh Botanic Garden.
Describes results with non-dimorphic Primula species. Such cases do not accord with CD’s view that characters are slowly acquired.
Thanks for criticism of his writing style.
