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.

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.

From John Scott 16 January 1863
Summary
Experiments to cut Laelia stigma from rostellum and then to fertilise rostellum are baffled by "a latent instinctive power". Somehow the pollen-tubes find their way to the style.
Suggests CD study variation in ferns.
