William Yarrell has assured him that call ducks cross freely with common varieties. CD would like a seven-day duckling and an old one that dies a natural death.
CD is depressed – all his experiments are going wrong, "all nature is perverse and will not do as I wish it". Feels he is getting out of his depth.
Mentions his paper ["Transportal of erratic boulders", Collected papers 1: 218–27]. Discusses ice-borne rock. Reference to unpublished paper on icebergs [?"Power of icebergs to make grooves", Collected papers 1: 252–5]. Remarks on scoring by icebergs. Comments on judgment of theories by Geological Society.
JDH to be appointed Assistant Director at Kew.
On where to publish seed-salting paper. Floating problem perhaps more important than germination.
CD upset because salted seeds do not float.
Asks WDF to induce schoolboys to collect eggs of lizards and snakes for him. He will see whether they float and stay alive on sea-water.
Reports on his experiments on action of sea-water on seeds and the bearing of his investigations on the theory of centres of creation and Edward Forbes’s theory of continental extensions to account for distribution of organic forms. CD’s experiments confirm germination powers were retained after 42 days’ immersion by seven out of eight kinds of seeds.
Has filled up CD’s paper [see 1674].
Distribution and relationships of alpine flora in U. S.
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].
Will be obliged if any reader can provide eggs of lizard Lacerta agilis. Wants to ascertain whether they float in sea-water. Offers reward of a few shillings to boys for collecting.
Discusses his account.
CD’s seed paper in Gardeners’ Chronicle [Collected papers 1: 255–8];
CD attacks Forbes’s "Atlantis".
Considers solutions to floating problem. Decides to test Azores seeds.
Photographs and drawings of CD.
Plant movement experiments with Hedysarum gyrans.
Is sorry to hear that WED has been ill.
Discusses pigeons and his pigeon work.
Notes on the interbreeding of different races of silkworm. [Forwarded with explanatory note by Edward Blyth.]
Asks JDH not to send H. C. Watson’s paper on Azores plants [Hooker’s Lond. J. Bot. 2 (1843): 1–9, 125–31, 394–408; 3 (1844): 582–617; 6 (1847): 380–97].
CD cannot endure trying all the Azorean seeds.
Seeds: worried they will turn into another barnacle job.
Studies plants colonising abandoned field.
Experiment on plant sleep movements.
CD objects to "Atlantis" because no evidence; does not affect species theory.
Finds Forbes’s continental theories, migration, and double creation are all unsatisfactory explanations of geographical distribution of plants.
Is currently working on problems of sea transport of plant species.
European plants on Australian Alps only explicable by double creations.
Suggests AG append ranges to the species in the new edition of his Manual.
Is interested in comparing the flora of U. S. with that of Britain and wishes to know the proportions to the whole of the great leading families and the numbers of species within genera. Would welcome information on which species AG considers to be "close" in the U. S.
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.
Asks whether THH will attend Council of Royal Society and speak for him on Joachim Barrande and J. D. Dana.
Thanks WDF for specimens and his great help to CD in his work on variations in young and adult ducks and poultry. Has found feet of tame adult ducks weigh twice as much as those of wild ones.
