Discusses auroral observation. Will reply to [John] Lefroy's letter soon. Wants grant proposals sent to outlying R.S.L. members for comments. Cannot attend Kew Committee meeting.

Writing article [for Encyclopaedia Britannica] on meteorology. Asks questions regarding work of [H. W.] Dove and [Thomas?] Taylor regarding cyclone and storm theory. Discusses barometric fluctuation.

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.

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.

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.

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.

Discusses desirability of middle latitude stations in North America. Impressed by the work of [A. D.] Bache.

JH cannot attend Aberdeen [B.A.A.S.] meeting due to severe illness. Will try to sketch draft of response to application to British and foreign governments for cooperation in magnetic projects.

Requests information concerning a letter to the Treasury, which ES had asked JH to write, regarding funding for [meteorological] stations in Vancouver, Shanghai, Newfoundland, and the Falkland Islands.

Will accompany ES to Kew Observatory. Serving as legatee for the recently deceased Elizabeth Baily, sister of Francis Baily.

Reluctant to recommend undertaking major scientific projects in colonies at government expense. Believes situation there will work itself out.

Thanks Mrs. Sabine for translation of third volume of Alexander von Humboldt's Kosmos. Admires its author. Questions references in notes. Discusses meeting for Wintringham Committee.

Describes in detail proceedings of a committee meeting, particularly noting remarks made about ES and stressing committee's wish to see evidence of progress.

Mentions cirrus cloud formations foreshadowing aurora. Is unable to attend R.S.L. committee meetings and concerned that 'outlying' members be able to relay opinions through letters.

Regarding report on magnetic observatories to be laid before R.S.L. president and council.

Thanks to [Francis] Ronalds for supply of paper. Comments on ES's discovery about direction of change in earth's magnetism, relating it to sun's and other electric currents. In this light, discusses auroras. Mentions abolishing of R.S.L. scientific committees and possible successor to John Caldecott.

Remarks on a correction in manual regarding some fluctuation of heating and cooling.
