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.
Magnetic phenomena move in opposite directions in the northern and southern hemispheres. This contradicts a report made by JH. Asks permission to omit JH's statements concerning this issue.
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.
Sends actinometer observations of 1841 and 1842, which he will publish. Asks JH to look them over and make comments.
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.
