Says AM’s letters on glacial action not publishable since they do not give facts. Suggests readings on the subject of glaciers. Expresses doubts about AM’s theory that Scandinavian glaciers brought the boulders he was studying.
Discusses a specimen of Mexican obsidian with an unusual laminated structure.
Asks whether LJ can throw light on this subject: "What are the checks and what the periods of life by which the increase of any given species is limited?" CD has been driven to conclude that species are mutable; allied species are co-descendants from common stocks.
Has been discussing wills and other legal matters with his father.
Discusses the connection between climate and vegetation. Believes that an equable climate is unfavourable to increase of species either by importation or modification of existing forms; illustrates his view with reference to particular floras. Hopes to acquire facts to support CD’s idea that isolation is important in producing new forms. Considers the floras of islands some of which do have distinctive species but others of which do not. Agrees that the wide ranges of cryptogams are a consequence of their means of dispersal. Asks for references to works on original creation and species mutability in order to get the best notions of "the (mad) theories of some men from Lamarck’s twaddle upwards".
Has never heard of species of same genus [of parasites] being found on both birds and mammals, or different genera and species being found on animals in the domestic and wild states. Implications of this for relationship of aperea and guinea-pig.

JH, William Whewell, George Peacock, Humphrey Lloyd, and Edward Sabine are appointed by the B.A.A.S. to study systems of simultaneous magnetical and meteorological observations. They will be granted £50.
J. H. Lefroy returned from McKenzie River [Canada] having established at least 350 magnetic stations between there and Red River, 'a fine pendant for [J. C.] Ross's survey' in southern hemisphere.' If expedition continues through winter, it will provide excellent survey of North American disturbances.
Francis Baily contracted with RT to print N. L. Lacaille's catalog of stars and J. J. L. Lalande's Histoire céleste. Account was suspended after Baily's death until B.A.A.S. meeting in York approved its continuation. Requests £300 from JH, chairman of grant committee.
