Summary

Thanks for Hedysarum.

Pleasure in identifying field plants.

Summary

When JDH goes to Germany, will he ask seed men if their marvellous true breeding lines are the result of selection.

Summary

Delighted to hear that JD’s research is continuing. CD has heard that JD’s paper will at last be published. He is flattered by the form [as a letter addressed to CD] of communication. [See 1651a and 1819a, published in Phil. Trans. R. S. 146 (1856): 21–9 and Proc. R. S. London 8 (1856–7): 27–33.]

Summary

Detailed response to JDH’s critique of sea transport and continental connection theories. JDH’s claim that low plants are widely distributed fits both theories.

Species theory does not touch origin of life.

Summary

JDH to be appointed Assistant Director at Kew.

On where to publish seed-salting paper. Floating problem perhaps more important than germination.

Summary

Geographical distribution. "Close" species. Hopes AG will write an essay on species.

Summary

On the transport of fish eggs by the water-beetle Dytiscus marginalis.

Summary

CD has begun seed-salting experiments. Wants JDH to write which seeds he expects to be easily killed [in salt water].

CD’s idea that coal-plants lived in salt water like mangroves made JDH savage.

Summary

Praise for JDH’s Flora Indica [J. D. Hooker and T. Thomson (1855)] from CD and C. J. F. Bunbury.

CD and J. S. Henslow dining in London. JDH invited.

Summary

Sends final results of his experiments on the vitality of various kinds of seeds immersed in sea-water. Corrects a false assumption he made in an earlier letter [1684] that plants with ripe seeds would float for some weeks. Now finds that they sink within a month. Since all the seeds he tried sank in sea-water, his experiments are of little or no use "in regard to the distribution of plants by drifting of their seeds across the sea".

Summary

Thanks for seeds. Feels "almost foiled" in his experiments on sea transport – has found few plants that float after more than a week’s immersion.

Sends a list of queries [see 1779] on hollyhocks to put to growers.

Summary

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.

Summary

Thanks AH for seeking reference. If AH cannot find Godron [see 1648] it is hopeless. Thanks for reference to C. F. Hornschuch.

Summary

He may insert his request for lizards’ eggs in Gardeners’ Chronicle.

His study of mongrel chicks is to ascertain whether the young of domestic breeds differ as much as their parents.

Has already sent a communication on means of distribution of plants by sea to Gardeners’ Chronicle [Collected papers 1: 255–8].

Summary

Thanks WDF for his help and reports on progress in "the Cock and Hen line of business". Has written to every quarter of the world for skins of poultry and pigeons.

As for seeds, Hooker and Bentham obstinately refuse to believe they can live even a few years in the ground.

Summary

Can AH give information about D. A. Godron, "De l’espèce et des races" [Mem. Soc. Sci. Lett. & Arts Nancy (1847): 182, 239–88]? CD unable to locate reference.

Summary

CD experiments: sowing seeds in fields; "breaking" seeds’ constitution with coloured light; plant hybridisation. Compiling works on hybridism.

Respect for W. B. Carpenter.

Note on "nectar secreting" to Gardeners’ Chronicle [Collected papers 1: 258–9].

Summary

Seeds of two tropical island plants have floated for ten days.

Summary

List of close species taken from AG’s Manual of botany [1848].

Summary

Sends London catalogue of British plants with close species marked.

Charges E. Forbes with fraudulent appropriation of others’ work.

Comments on, and cites possible cases of, CD’s imagined rule that individuals of one or more species in a genus vary in some of those characters by which the species of that genus are distinguished.
