J. D. Dana’s congratulations on JL’s marriage.

Will send MS on one point of geographical distribution. It is "of infinite importance" that JDH see it, for CD has never felt such difficulty in deciding what to do.
Wants capsules of aquatic plants, to float in sea-water.
Note accompanying MS of part of chapter 11 ["Geographical distribution"] of Natural selection [1975].
Podostemaceae flowering under water.
Agrees with JDH that Cytisus report [presumably of a large change] not sound. CD pleased because, if true, species would change too quickly.
Responds to CD’s queries on Sierra Leone: fertility of European animals introduced to W. Africa, relationship of health and complexion of Europeans, etc.
CD coming to London.
Read JDH’s review [Hooker’s Kew J. Bot. 8 (1856): 54–64 et seq.] of Alphonse de Candolle’s Géographie botanique raisonnée [1855] long ago.
Sends JDH part of MS for chapter 3 of Natural selection ["Possibility of all organic beings crossing"] to be corrected and returned.
JDH’s report of Podostemon flowering cleistogamously under water in Bengal.
[Copious revision by JDH.]
CD sorry he had to leave the Hookers abruptly to catch his train.
Comments on JL’s paper on Daphnia, ["An account of methods of reproduction in Daphnia and of the structure of the ephippium", Philos. Trans. R. Soc. Lond. 147 (1857): 79–100].
Discusses arthropod structure and the nature of the corium.
Outlines the ranges of northern U. S. species common to Europe. Hopes to investigate the resemblances between the floras of the north-eastern U. S. and western Europe. Discusses routes by which alpine plants appear to have reached U. S.
JDH approves MS section on geographical distribution.
Never felt so shaky about species before.
His objections to some mechanisms of distribution that CD proposes.
Greatly interested in CD’s experiments with seeds in salt water [see "Action of sea-water on seeds", Collected papers 1: 264–73]. Believes CD exaggerates the force of the objection, against migration, that seeds tend to sink.
CD relieved by JDH’s positive response to his MS.
CD continues observations on means of transport.
JDH’s Raoul Island paper [J. Linn. Soc. Lond. (Bot.) 22 (1857): 133–41], showing continuity of vegetation with New Zealand, best evidence yet of continental extension.
Describes the funeral of Aunt Sarah [Elizabeth Wedgwood].
Believes he can give CD information on Mammalia of St Thomas [São Tomé, Gulf of Guinea]. Quotes from a Portuguese history of the islands on unique species of monkeys and civet cats found there.
CD finds JDH’s objections to a mundane cold period significant, and he endeavours to show how they do not rule out mutability.
He is writing on crossing.
CD encloses letter from Asa Gray, although it is critical of JDH.
Role of struggle in forming species in retreat from advancing glaciers.
