Sends observations he made on Fungia during Beagle voyage. Asks CS to make corrections in style or names of parts as he sees fit.

CD has heard from the Treasury; they will pay the account [for the Zoology] as soon as Smith, Elder & Co. like.

Thanks JWF and G. R. Waterhouse for cirripede specimens.

Asks to borrow FK’s specimen of Conia rosea. Would like to know if FK collected it himself [in S. Africa] or was given it, because CD has a closely allied species from Australia, which surprises him. [See Living Cirripedia 2: 335.]

Has received [C. L.?] Brehm’s work [unspecified]. Will return it in two or three weeks.

Extremely sorry for trouble he has given about his signature.

One child dangerously ill with diphtheria, another with much fever.

Asks JP to remember him if anything occurs to him "in regard to inheritance at corresponding or rather earlier ages". Sends JP a few examples for his "Chronometry of life". CD is sure he often met with striking facts but he disregarded them. "Deviations alone would have struck me."

Effects of different climates on breeding periods.

Thanks JP for bearing in mind his strong wish to learn any facts on inheritance at corresponding ages, and on correlation of growth.

JP’s case of teeth affected by syphilitic parents seems very curious. Would like to hear a few particulars when they meet.

CD’s health remains bad and as he grows older he becomes weaker.

Thanks for invitation [to stay with GR at Oxford], but his poor state of health requires him to stay in private lodgings.

CD’s plans are uncertain because of his daughter’s [Henrietta Darwin] fever.

If GR would kindly reserve rooms for CD near college, CD will write before the meeting [of British Association at Oxford] if he is prevented from coming.

Agrees with GR’s remarks on Asa Gray’s pamphlet.

New edition of Origin to appear immediately.

Fact of clubbed fingernails in cyanosis quite new to CD. Asks for information.

Thanks for explanation of cyanosis and clubbed nails.

Hopes GR will work out point about mucus tubes.

Thanks correspondent for a remarkable instance of inheritance [not specified].

Thanks for orchids and other flowers.

Will send photograph.

Declines, regretfully, to contribute to or to have his name appear on a new magazine.

Thanks for answers to CD’s questions; would appreciate any new information on similarity of moths of distinct races.

CD has been "atrociously abused by religious countrymen, but it does not hurt except when it comes from an old friend like Prof. Owen".

Wishes French translator of Origin had known more natural history.

CD needs first volume of the second series [of Trans. R. Hortic. Soc. Lond.].

Recommends paper by John Scott to be read at Linnean Society.

Asks TCE to verify whether otter-hounds have more skin between their toes than other hounds. Also interested in cases of infertile matings between normally fertile individuals.
