Summary

CD too unwell to read. JS should not send Primula paper MS until CD returns home.

Summary

Urges JS to publish on orchid pollen-tubes.

Suggests comparing stigmatic tissue of sterile hybrids and fertile parent; he would expect hybrid plant’s cell contents not to be coagulated after 24 hours in spirits of wine.

Suggests JS coat orchid stigmas with plaster of Paris for his work on rostellar germination.

Asks for list of "bud-variation" cases; CD has devoted a chapter to the subject.

Inquiries about I. Anderson-Henry’s observational competence.

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.

Summary

Discusses Darjeeling position. Thanks CD for advice.

Will send orchid paper [see 4087].

Summary

CD agrees about reversion.

The discovery of crossing in cryptogams is very interesting.

Summary

Has written to Hooker for his advice about the Darjeeling position. JS should not refuse the position on account of his experiments.

Summary

His orchid paper limited because he does not give illustrations from distinct genera.

Discusses the self- and cross-fertility of coloured primrose varieties. Thanks CD for tables of unpublished Primula work.

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

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.

Received maize varieties from CD.

Summary

CD does not think he could be wrong about the stigma of Bolbophyllum.

Will not write up Drosera for years.

Praises JS’s experiments. Invites him to send a paper to Linnean Society.

L. C. Treviranus says all species of Primula present two forms except P. longiflora.

Summary

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.

Summary

Supports, in his orchid paper, CD’s view that sterility occurs at random [Trans. Bot. Soc. Edinburgh 7 (1863): 543–50].

Cannot get his Drosera paper published [abstract in Edinburgh New Philos. J. 2d ser. 17 (1863): 317–18].

Summary

Thanks JS for orchid paper [Trans. Bot. Soc. Edinburgh 7 (1863): 543–50]. JS presents excellent new facts on sterility of orchids.

His argument that coloured primroses are not hybrids is good, as is idea of discovering primrose parentage by breeding for colours.

Summary

Sends abstract from Edinburgh Courant of his orchid sterility paper [see 4087]. Balfour altered title to obscure its theoretical nature.

Sends specimens showing curious variation.

Summary

Regrets CD’s poor health.

"Do not return Primula MS."

Summary

CD’s great interest in JS’s work on fertility of Primula crosses.

Thanks for Passiflora trials.

"By no means modify even in slightest degree any result."

CD wishes he had counted rather than weighed Primula seeds.

Summary

Hooker is impressed by JS’s MS on closing of stigma.

He will help find him a position. Hooker says if it is known that JS agrees with CD’s views, he will be unpopular in Edinburgh.

Summary

Sends Asa Gray letter to JDH. Gray’s "Coolness about England and U. S. beats anything".

John Scott’s difficulties at Edinburgh Botanic Garden.

JS’s paper on Primula crossing experiments.

Sends MS note about closing of stigma in orchids being dependent on affinity of pollen and independent of protusion of pollen-tubes.

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.

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.
