Suggests postponing meeting of Wintringham Bequest Committee. Will bring up [Edward] Cooper's letter about comet memoir at next council meeting. Has worked out cost reductions for printing of R.S.P.T.
No summary available.
Discusses regulations of bequest, which will benefit chemistry and physics. Discusses relationship between solar spot period and magnetic disturbances. Wants JH's comments on paper regarding this topic.
Believes similarity of period of solar spots and that of terrestrial magnetic variation is more than coincidental.
Discusses magnetic observations from Toronto and Hobarton from the 1840s. Attempting to determine when range of variation was greatest.
Stopped compilation of comet orbits because it had already been done. Would provide money from donation fund to distribute copies of this information.
Hopes JH will present application of Kew Committee for financial aid at next council meeting. Includes suggestions for maximizing credibility of application.

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.
Recommends use of photography to prepare records of sunspot activity. Makes suggestions on how this could be done most effectively.
Glad JH is recovering and free from official duties [at the Mint]. Discusses his upcoming papers regarding magnetism.
Comments on a proposed grant to publish T. R. Robinson's Armagh observations.
Returns polar maps. Advises on methods of map projection, favoring polar projection. Working on new maps.
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.
Discusses [H. W.] Dove's works regarding rotating storms. New information from Russian observatories gives a more complete understanding of the phenomenon. Has not seen Keith Johnson's new edition of Physical Atlas.
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.
Glad to know which of ES's papers JH has. Sends another along with maps from [Keith] Johnson's Physical Atlas. Discusses JH's ideas regarding relationship between solar spots and magnetic disturbances.
Mentions [P.] Plantamour's memoir on barometer and a criticism by Mr. Dilams[?]. Comprehending why variations of magnetic disturbances correspond in period with terrestrial year is difficult.
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.
