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.

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.

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

Suggests experiments on peloria.

Wants to count seed of the self-fertile red cowslip with equal stamens and styles.

Can send account of Hottonia.

Impressed by JS’s attempts to fertilise Gongora.

CD has large collection of notes on orchids, but does not know when he will publish on them again.

Asks for JS’s papers on sterility of individual orchids and on Drosera.

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

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.

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.

CD has spoken to Hooker of JS’s scientific merit, but has not suggested him for a colonial appointment.

Advice on style of writing.

Making extensive extract of JS’s orchid paper to communicate to Linnean Society [J. Linn. Soc. Lond. (Bot.) 8 (1865): 162–7].

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.

Encourages JS to continue work on coloured primrose. No one has noticed this since Gärtner. CD will send his own data for JS’s use and will read MS when ready. Advises JS to repeat experiments if evidence is weak – for his reputation’s sake and for satisfaction at fully establishing a fact.

Treviranus made a slip of pen in writing of Primula longiflora as short-styled.

Has read JS’s paper [MS of "Observations on the functions and structure of the reproductive organs in the Primulaceae", J. Linn. Soc. Lond. (Bot.) 8 (1865): 78–126] which has interested him greatly. Will communicate it to the Linnean Society if JS carries out a few corrections.

Would like to hear about his Verbascum and Passiflora experiments.

JS’s Primula paper was read at the Linnean Society and praised warmly by G. Bentham. Hooker was not present.

Bentham so impressed with JS’s paper that he is invited to become Associate Member of Linnean Society.

Letter of recommendation stating his high opinion of John Scott.

Supports relocating the Calcutta Botanic Garden to a site near the Himalayas.

JS should not consider repaying CD; the money was a gift, not a loan.

JS’s information on expression is the best he has received.

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.
