Will undertake magnetic report except parts for which research is not yet completed. Needs [Johann] Lamont's recommendation regarding experiments. Sends [James] Ross's observations for perusal.
Discusses state of science in France. Magnetic instruments were ordered for Algiers, but ES is uncertain whether they left Paris. Will send portion of magnetic report and letter from [A. D.] Bache among other things.
Sends actinometer returns for remarks and suggestions. Mentions public dinner for scientific community.
Sends actinometric returns and drawing of comet from Hobarton Magnetic Observatory. [John] Lefroy's expedition in U.S. and Canada is going well. Received the observations from Algiers.
Encloses letter from Dr. [John] Locke. Wants to loan him a magnetometer to set up a station at Cincinnati. Received [John] Caldecott's volume of JH's observations. Thinks publishing costs will be high.
Encloses bills for the Committee. [Johann] Lamont will be in England that year to correct continental surveys. Glad JH will be president [of B.A.A.S. meeting] at Cambridge.

Received notes on omission of passage [1844-9-26] in good time. Asks JH to return proof of report. Regaining strength before going back to study Toronto volume.
Edinburgh [Review] named someone else as the person who found the true correction of the rate of pendulums on account of the atmospheric medium. ES actually discovered the correction first. Discusses [James] Ross's intensity ovals.
Sending proof copies of the report on the Toronto meteorological observations. Asks JH to make suggestions for corrections and improvements.
Obliged for JH's comments regarding pendulum apparatus. Discusses the article that wrongly attributes ES's discovery to [F. W.] Bessel and [Francis] Baily.

Discusses ES's experiments with convertible and travelling pendulums. Asks how 'für vaterländische Cultur' is to be translated for the list of societies.
Pleased that JH agrees on removal of tail pieces and moveable weights from pendulums. Discusses pendulum experiments in air and vacuums.
Discusses the best pendulum models inside and outside a vacuum apparatus. ES will be given credit for improving the manipulation of pendulums. Makes several other comments regarding pendulums.
Will attend to JH's wishes regarding the correspondence. Discusses the buoyancy correction for particular types of pendulums. Asks if JH has received the magnetic results from Geneva.
Sends 30 copies of JH's letters by coach. Will charge to the B.A.A.S. account.
Objection to G. B Airy's suggestion unexpected. Will see Dean of Ely [George Peacock] soon. Must review foreign letters to be sure none of consequence were omitted. Sends copy of the Toronto meteorology.
