Thanks ES for his paper. Sun spot activity should increase in 1857. Discusses his own earlier ideas concerning relationship between sun spots and Aurora Borealis.
Discusses advantages of different magnetic charts. Grateful for [P.] Plantamour's observations. Satisfied with [J. R.] Wolf's period of 11.11 years for solar spots.
Heard ES recommended JH write an article for Edinburgh Review on terrestrial magnetism. Asks what he should read to write this article. Photographs ES sent of sun not promising.
Willing to write article if Quarterly [Review] will publish it, if he may take his time writing, and if ES will provide aid regarding meteorology and magnetism.

Thanks ES for receipt of information about magnetic curves and the work of [A. D.] Bache. JH is glad to hear ES is back to active work again, but JH says he is too ill to go to the B.A.A.S. meeting [in Aberdeen].
[Extract] Learned that JH was appointed by R.S.L. to committee to cooperate with B.A.A.S. to promote continuance of terrestrial magnetism survey. Asks ES to send committee summary of results already obtained and ES's opinion of how best to conduct future observations.
JH's improved health would allow him, if asked, to chair the Chemical Section at the B.A.A.S meeting. Notes that JH, G. B. Airy, William Whewell, and George Peacock have been appointed to a committee to cooperate with the B.A.A.S. committee dealing with the continuation of terrestrial magnetism observations.
Is glad to sign certificate. Complains about tendency of Alexander von Humboldt, whose volume Mrs. Sabine is translating, to ignore other scientists' work.
Must hold to 1/290 as measure of ellipticity. Committee agrees to recommend continuance of magnetic observations if JH will continue to do what he has done in the past.
Describes in detail proceedings of a committee meeting, particularly noting remarks made about ES and stressing committee's wish to see evidence of progress.
Sends G. B. Airy's remarks concerning ES's last communication. Discusses future of observatories. Asks ES to indicate which observatories he feels are most important.
Invites ES and his wife [at St. Leonard's] to visit . JH is impressed with ES's ability to develop a working plan for terrestrial magnetism observations. Is prepared to write a review article [about magnetism?] if invited, but JH refuses to write such articles and offer them 'for acceptance or rejection.'
Has incorporated ES's suggestions into the draft report about [the University of] Kasan.
