Summary

On JAHdeB’s discovery of Cretaceous Chthamalus. Cites his own acceptance of negative evidence about Chthamali in Fossil Lepadidae.

Comments on JAHdeB’s cirripede drawings.

Summary

The information correspondent hopes to get from M.-J.-P. Flourens will be valuable.

CD is keeping all varieties of pigeons, poultry, ducks, etc. for his work on variation.

Summary

Thanks SC for his interesting account of the state of the colony. SC was wise to settle there where his sons have much better prospects.

Has finished his book on barnacles [1854]. Royal Medal awarded him chiefly for this work.

Asks SC whether he has observed any odd imported breeds of poultry, for his work on variation of species.

Summary

Thanks for sending paper on geological development (Dana 1856). Discusses infertility of species. Discusses first part of Asa Gray’s paper (A. Gray 1856–7). Thanks for note on the Cave Rat. Discusses a new species of fossil cirripede, in the genus Chthamalus. Explains his interest in pigeon breeding.

Summary

Sends a cultivated specimen of Myosotis (first generation) grown from seed sent by JSH. Asks for a tuft of flower.

Hopes JSH will publish a book on teaching botany, because he has no idea how to begin with his children.

Summary

Preparing paper on seed-soaking for Linnean Society ["Action of sea-water on seeds", Collected papers 1: 264–73]. Wants to use MJB’s results. Lost ardour when he found seeds would not float.

Has grown MJB’s purest pea seeds and got a few variants. Gärtner’s experiments suggest direct action of pollen, but CD thinks it is "mere variation".

Summary

Condemns theory of Edward Forbes and others that many islands were formerly connected to South America by now submerged continents.

Summary

W. J. Hooker thinks Harvey will be willing to give information on reproduction of higher marine plants.

Summary

It seems improper that his advances to G. B. Sowerby Jr for payment of engravings should not have been mentioned to Council of Ray Society. His appreciation of the Society.

Summary

Whether or not there should be movement of particles according to Tyndall’s theory of glacial action ["Observations on glaciers", Not. Proc. R. Inst. G. B. 2: 54–8, 441–3].

CD subscribes to H. C. Sorby’s view of gneiss [Edinburgh New Philos. J. 55 (1853): 137–50].

Seed-salting.

Pigeons.

Significant differences in skeletons of domesticated rabbits.

Summary

Thanks EWVH for his offer but he is not likely to go to London soon to visit John Leadbeater, the bird dealer; he could take a rock pigeon for comparison, but other skins he would have compare at the British Museum.

Would be obliged if EWVH could investigate domestic species in Egypt, especially a type of dog depicted in ancient monuments; and he is particularly interested in tumbler pigeons.

Summary

Comments on TVW’s book [On the variation of species with special reference to the Insecta (1856)].

On TVW’s Unitarianism. Predicts TVW will fall further away from Christianity.

[Letter sent by TVW to Charles Lyell.]

Summary

Huxley’s "vehement" [Royal Institution?] Lectures make it difficult to propose him for Athenaeum.

Summary

JL is studying Cynipidae. CD sends galls for his examination.

Summary

Reminds WBDM of his promise of information about the quartz boulders and an iceberg with fragment of rock seen in southern ocean.

Sends other questions [on separate sheet (missing)] which WBDM will think ridiculous, but all bear on plants and animals under domestication.

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

Tristan da Cunha flora.

Aquatic plants.

Density and diversity of plants in small plots in Kent, Keeling Islands, and Himalayas.

Summary

Asks for information on geographical distribution of ascidians; are any closely allied species or genera found in north and south temperate zones that do not have representatives in the tropics?

Answers some questions on [cirripede] antennae.

If THH ever sees a tree washed ashore, will he observe whether any earth is embedded between roots?

Summary

Has received some poultry from various parts of the world.

CD is glad that WBT is describing the birds that he acquires.

Summary

Suggests affinities of the U. S. flora that he considers would be worth investigating. Wants to know the ranges of species in large and small genera.

Questions AG on naturalised plants; whether any are social in U. S. which are not so elsewhere and how variable they are compared with indigenous species. Would like to know of any differences in the variability of species at different points of their ranges and also the physical states of plants at the extremes of their ranges.
