Orders Andrew Knight’s paper ["An account of some experiments on the fecundation of vegetables", Philos. Trans. R. Soc. Lond. (1799): 195–204] and J. E. Gray’s book [Gleanings from the menagerie and aviary at Knowsley Hall (1846)].
Asks JM for four copies of his Journal of researches [2d ed.] at wholesale price. Also asks for total number of copies sold.
Mr Hardy, CD’s tenant at Beesby, has spent £105 on improvements to the farm. JH suggests different ways of recompensing the tenant, and asks for CD’s decision.
Thanks for gift [of books requested in 1026]. Sale is a good deal more than he had anticipated.
Cites cases of leguminous plants whose cleistogamic flowers produce more seed than perfect flowers. [See Forms of flowers, p. 326.]
Informs CD that in his experience with peas he has never found the seed to deteriorate.
Wants accurate information on "the economy of nature". Is interested in how far the struggle with other species checks the northern range of any species.
Thanks John Storey for information.
Thanks for case of inherited malconformation.
Asks to borrow C. L. Brehm’s book [Handbuch der Naturgeschichte aller Vögel Deutschlands (1831)]. Wants to see how far Brehm went in splitting species.
Took finches from Madeira to British Museum.
Adds comments to a list of Cape of Good Hope plants which are also European and gives some additions to the list [see Natural selection, p. 552].
Regrets he cannot help JL; the point [unspecified] was always a trouble to CD also.
Has been to a poultry show.
Asks for the return of a lens.
JDH not happy with CD’s explanation of the absence of north temperate forms in the Southern Hemisphere, given his explanation for the spread of sub-arctic forms to the south. [CD’s note is in response to JDH’s criticism.]
