Describes his work with seeds in salt water.

For his experiments he would like seeds collected from plants that grow both near Hitcham and in the Azores.

Explains again what JSH should do in marking "close species".

Thanks JSH for seeds.

Clarifies his request about marking [London] catalogue [of British plants] – JSH is to mark those he thinks really are species, but which are very closely allied to some other species.

Asks for advice on establishing a control group in his experiments to produce sports and varieties of Lychnis diurna.

Seeks seeds of wild Dianthus for hybridising and producing varieties.

Sends a list of 22 plants that grow at Hitcham and in the Azores and are, according to H. C. Watson, least likely to have been imported [by man]. Will pay the little girls of Hitcham liberally to collect the seeds for his experiments.

Thanks JSH for all he has done. His botanical little girls are marvellous. His marking of the list of dubious species is what CD wanted. Explains that he wanted to ascertain whether closely allied forms belong to large or small genera.

Invites JSH to dine at CD’s brother’s house in London.

Delighted JSH can dine. Has invited Hooker.

Thanks him for Lychnis seed.

Asks for umbel of wild celery. Wants to ascertain whether wild or tame plants produce most seed.
