Magnetic questions have been sent to foreign observers but not the British. Why?

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.

J. F. Daniell informs JL that the table was calculated by William Galbraith. James Apjohn states everyone is in agreement that the absolute heat of steam is constant, but JL disagrees. Intends raising the matter of John Southern's experiments at the next meeting of the B.A.A.S.

Obliged by JH's letter. Would he let him know what he thinks of raising the matter of repeating John Southern's experiments. His own eldest son has gone to Langley; he shows little aptitude for figures but a decided turn for Natural History.

Thanks AD for having pointed out an error in one of JH's papers.

A copy of the question circular, signed by JH, sent to GA [see GA's 1844-12-17].

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.

States the case for the accuracy of the observations and reports of the discoveries of the sixth and seventh satellites of Saturn made by JH's father, William. [This letter seems to be tied to JH's 1844-7-22 in terms of date of writing.]

JM is traveling in Germany for some time and intends to end up at a scientific conference in Bremen. He encourages JH to try to attend that conference so they may become acquainted.

Regrets to hear of AM's sad losses. Would like him to withdraw quarterly amounts and give them to Caroline Herschel.

About the financial arrangements for Caroline Herschel [see JH's 1844-1-2], and news of her health.

B.A.A.S. have been trying to arrange their 1846 meeting at Cambridge. William Whewell alone is opposed to this suggestion. Everyone agrees that JH should be the next president when the Dean of Ely retires. Can they have JH's views.

Regrets he made a mistake in his letter; he meant 1845, not 1846. William Whewell has been overruled and the B.A.A.S. are to meet at Cambridge in June 1845.

Can raise no objections to being president of the B.A.A.S. for 1845, but will be unable to be in York this year.

Rejoiced to receive his friendly letter, even though they have no hopes of seeing him in 1846. They are still on friendly terms with William Whewell, though they disagree on the Cambridge meeting.

Gives news of the death of JN's father.

Offering hospitality to JH should he attend the B.A.A.S. meeting at York. Has been studying the theory of the manufacture of achromatic telescopes. Comments on the quality of glass available. Swiss seems to be best, though expensive. Deplores the loss of Francis Baily.

Glad to hear that there is a possibility that JH will visit York. Another expected visitor will be T. Donkin, brother of Bryan Donkin.
