Thanks LJ for his book [Observations in meteorology (1858)].
CD has been working on his species book [Natural selection].
Has become dreadfully heterodox on immutability of species.
His work on pigeons: variation under domestication throws the greatest light on variation in a state of nature.
List of close species taken from AG’s Manual of botany [1848].
Discusses the variation of species in large and small genera.
Thanks AG for his list of close species.
Laments the slow progress he makes with his book [Natural selection].
No summary available.
Thanks AAG for procuring an authoritative answer from T. M. Brewer on the habits of the [American] cuckoo. Surprised William Yarrell erred so much.
Wishes AAG had time to give an account of Japanese shells, which would be interesting from the geographical point of view.

Sending some publications to show the kind of work he is doing. Has read JH's Admiralty Manual and congratulates him on its authority. Has been reading J. P. Espy's Fourth Report. Note of W. J. S. Pullen's soundings in the South Atlantic.
Asks LJ to lend him a copy of his paper ["Variation of species", Rep. BAAS 26 (1856): 101–5] and any notes or references he has. Although CD has a large accumulation of facts, it is impossible to see and consider too many.
His health is poor.
Asa Gray’s criticism of Buckle and his comments on large and small genera.
CD suspects glacial epoch immensely long. Rates of organic change too variable to make them a good measure of geological time.
Bees’ cells are a difficulty for theory.
No summary available.
Comments on wind and current charts JH has received from RF.
CD will go over his pigeon MS and then dispose of all his birds. Has Burmese fowls’ skins if WBT is interested.
A set of questions CD prepared for his meeting with WHM to discuss the geometry of bees’ cells.
Replies to specific requests by committee for summary of benefits from research in terrestrial magnetism and meteorology and for ES's opinion on continuance of observatories. [JH annotation: Routing list to G. B. Airy, George Peacock, and William Whewell.]
Asks WDF for facts about stripes in horses and ponies.
Health has been very bad.
Is much obliged and honoured by the Diploma of the Geographical Society of Vienna.

Bees’ cells; GRW thinks hexagonal shape is accidental. Encloses notes on cells of Icaria.
[Copy of some rough notes.] References about species. Variations within species.
