Fertilisation of barberries.
Passiflora.
Is continuing his experiments on the comparative growth of crossed and self-fertilised plants.
Encloses seeds from Fritz Müller, of a species of Passiflora, fertilised by a humble-bee.
Was aware of Maine’s view but never thought of its extension to morals. Cannot avoid thinking that personal property like flint tools must have "strictly belonged to individuals as much as a bone to a dog".
Confesses to intense hatred of the bee [orchid] for its anomalous perpetual self-fertilisation.
THF’s article in Nature ["The fertilisation of a few papilionaceous flowers", 6 (1872): 478–80, 498–501] is extremely good.
Suspects he now has answer to why common peas and sweetpeas hardly ever intercross, a point which half drove CD mad for years.

Thanks THF for information from Colonial Office on population statistics showing the inhabitants of some areas are far from becoming sterile.
Delighted to hear about Coronilla. Urges publication ["Fertilisation of papilionaceous flowers– Coronilla", Nature 10 (1874): 169–70].
Has read THF’s article on Coronilla [see 9400] – "a very curious case"; is troubled by C. emerus.
Hooker is greatly overworked at Kew and is trying to get the Government to provide some help. CD hopes THF will take an interest in the matter and forwards a copy of JDH’s application for an assistant.
Describes difficulty of conditions for the experiment with Drosera suggested by THF.
THF is seeking advice regarding the selection of an entomologist to carry out some duties [apparently pest destruction].
CD is delighted with report from THF about activity of worms in Roman-British ruins at Abinger.
Thanks THF for the diary of worm activity at Abinger site.
THF would do a good deal if he gets Agricultural Society to rear cross-fertilised seeds. Society excellent channel for distribution of fungus-proof variety [of potato]. If James Torbitt will carry on work another year, CD will offer him £100.
Describes James Torbitt’s plan for producing disease-resistant potato varieties. [Letter is an earlier version of 11406.]
