Adds a point to his previous letter regarding the buoyancy of birds and their soaring capacity.
Asks CD to renew his former offer to propose him for the Royal Society, as Michael Foster, now on the Council, is unable to do so.
Plants received from JDH.
Requests he verify an identification by Fritz Müller.
FM’s new position in Rio.
CD interested in nature of surface deposits at Rio.
Sends a copy of Cross and self-fertilisation.
Has examined the specimens of Boronia pinnata. No evidence of two distinct bodies of individuals.
Asks whether extra-American species of Aegiphila are heterostyled.
CD is glad to propose FMB for Royal Society. Explains information and certificates needed.
Believes Aegiphila to be exclusively American.
Contrasts fertilisation of Australian Acacia with Brazilian Mimosa.
Complains at Albert Günther’s imputations against Charles Wyville Thomson [as a result of the dispute between Thomson and the British Museum, regarding the disposal of the specimens from the Challenger].

Responds to CD’s new work [Cross and self-fertilisation]. Suggests results might have been more convincing if CD had measured weights instead of heights. The fact that infertile hybrids have not been produced means that the "one great objection" has not been got rid of: the physiological characteristic of species. Suggests an experiment to produce "sterile mongrels" which would remove objection.

Michael Foster approves of names FMB suggested CD apply to [in proposing FMB to the Royal Society] and adds George Allman, Foster, W. H. Flower, and P. M. Duncan, the only biologists on the Council.
Lists his chief publications and suggests names of biologists in the Royal Society whom CD might ask to sign his nomination certificate.
Corrects Descent [1: 294] on inheritance of tortoise-shell colour in cats. It does not violate rule that characters appearing late in one sex are transmitted exclusively to the same sex.
JDH has sent a short-styled Forsythia from Kew. CD surmises that all Forsythia at Kew may be short-styled, hence he is curious to know whether they set seed.
CD is eager for further information about Lagerstroemia, which is sterile with its own pollen. Does the collection of dried plants reveal more than one form? Plans to republish papers on dimorphism.
Thanks SS for present of Life of a Scotch naturalist [1876]. Has read every one of his biographies with "extreme pleasure".
Thanks for Cross and self-fertilisation.
Discusses geographical implications of inbreeding. Can the length of time an insular flora has been isolated be estimated by its weakness due to inbreeding?
