Thanks CD for acknowledging receipt of JDC’s book The antelope and deer of America [1877].
Castration suppresses deer antlers.
Thanks CD for acknowledging receipt of JDC’s book The antelope and deer of America [1877].
Castration suppresses deer antlers.
No summary available.
Thanks for information, which will be useful if CD ever brings out a corrected edition of his book [Forms of flowers].
AdeC’s two letters on bloom will be very useful; his remarks on evaporation and absorption seem very just. CD has made few experiments as yet. The investigation has been tedious and difficult.
CD has made clear that in Cross and self-fertilisation he had not intended to suggest that autogamie (fertilisation of a flower by its own pollen) is superior to gitonogamie (fertilisation of a flower by one on the same plant).

Sends article and photograph of abnormally hairy family.
Mentions death of his student, Rudolf von Willemoes-Suhm.

Thanks GdeS for communicating his discovery. It is especially important at a time when several naturalists have declared that development occurs quite suddenly at intervals. Joseph Le Conte in N. America urges that even new families and orders are developed within an extremely short period.
Movements in cotyledons; outlines tracing technique. [A tracing of movements of red cabbage cotyledon enclosed.]
Another issue of Origin will be needed for Murray’s annual sale. Has CD any corrections?
Asks whether CD considers it possible that a mollusc could poison anyone on contact, as RD has heard from missionaries about a certain South Sea variety.

CD is occupied with vegetable physiology.
Prefers to read MS when published.
Pleased CD is satisfied with translation of Cross and self-fertilisation.
Sends £20 royalties for Insectivorous plants (700 sold).
Cannot give information requested. Seems incredible that mere contact should be poisonous.
Thanks CTEvS for photographs of human abnormality;
regrets death of Rudolf von Willemoes-Suhm.
CD desires her to say that the cream of THF’s letter of congratulations about William [Darwin]’s marriage [to Sara Sedgwick] lay in the P.S. about "the beloved worms, and not in any such trifles as marrying, &c".
Gives a possible explanation of exceptions to CD’s observation [Descent, ch. 7] that characters correlated with one sex tend to appear late in life.
