Changing a date of meeting for the magnetic committee of the B.A.A.S., and inviting GA to be there.
Thanks GA for offer of accommodation [see GA's 1844-11-2], but JH says he must stay with Miss [Elizabeth] Baily at Tavistock Place.
Is publishing a work on rare atmospheric phenomena. Lists names of persons who have assisted with observations. Would like to inscribe the book to JH.
Regarding L. F. Menabrea's papers, thinks he is a good mathematician. Is not so sure about Augusta A. King's (Lady L[ovelace]) notes.
Asks HL for comments about the question of continuing the magnetic observations.
Observed Comet Mauvais. Is grateful for JH's intervention on Observatory matters. Extra Meridian Instruments defective. Continues observations of variables. F. E. Wilmot's land survey cancelled. Magnetic survey progressing. Mary Maclear ailing.
[Form letter] Asks recipients to consider value of magnetical research supported by British government and submit opinions on whether B.A.A.S. should seek continuation of this support after present agreement with government expires at end of 1845.
Not acquainted with proposal by A. T. Kupffer. Replies to queries by B.A.A.S. committee regarding continuation of magnetic and meteorological observatories. Expects self-registering instruments to supersede human observers soon.
GP prefers to meet on Saturday at Somerset House, rather than on Friday as JH proposed.
Accepts JH's invitation to attend the meeting [see JH's 1844-11-1], and offers JH accommodation for the night.
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.
Responds to ES's request for JH's remarks on the mode of registering and printing the actinometer observations.
Regrets that he cannot offer JH the information he needs regarding the stature of service-men, but suggests places for further searching. Shares observations about relationships between dew point and barometer.
[John] Lee has a silhouette of Caroline Herschel as a young lady; would JH like it? Discusses whether JH should include Francis Baily's relationship to his family in JH's memoir on Baily. Names those to whom he plans to give copies of Baily's portrait.
Does not think Francis Baily's relatives should take part in JH's presentation on Baily to the R.A.S., but if they have asked to do so, they should not be refused. Would like a copy of Caroline Herschel's silhouette. Is'facing the engraver's hands' with his nebula, and must get the plate of JH's portrait, which RS placed at the disposal of the Duke of Northumberland.
Adds remarks to his previous comments [JH 1344-11-17] on Francis Baily's relatives participating in the memorial to Baily.
