Asks JH to read ES's publications for the R.S.L. proceedings concerning colonial magnetic observations. Wishes JH could see R.S.L.'s recent accomplishments in magnetism.
Glad JH is reviewing advancement of science by R.S.L. members. Disappointed that little was accomplished in certain areas where more was expected.
Sends section X and earlier paper on Kew and Nertschinsk disturbances, which supply key to theory of magnetic disturbances.
Discusses ellipticity and results of [G. B.] Airy and [F. W.] Bessel. Also, [Alexander von] Humboldt's magnetic results.
Replies to specific requests by committee for summary of benefits from research in terrestrial magnetism and meteorology and for ES's opinion on continuance of observatories. [JH annotation: Routing list to G. B. Airy, George Peacock, and William Whewell.]
Sends proofs of editor's notes from vol. 4 of [Elizabeth J. Sabine's] translation of Alexander von Humboldt's] Cosmos. Assumes that JH and magnetic committee members all have copies of 'Introduction' to vol. 3 of Toronto observations. Managed to clear up 'mystification' in J. B. Biot's account of pendulum experiments.
ES's paper on magnetic observatories in colonies is same as 'Introduction' to vol. 3 of Toronto observations. Publisher has delayed [Elizabeth J. Sabine's] translation of vol. 4 of Cosmos; please send JH's copy of 'Editor's Notes' to other members of magnetic committee. J. B. Biot intentionally subordinated English pendulum experiments to French experiments, and Alexander von Humboldt was misled.
Current activities at magnetic observatories at Cape of Good Hope, Hobart [Tasmania], and Toronto. Future avenues for research in terrestrial magnetism include correlation with sunspot cycles, annual seasons, parallels of latitude, and lunar position. Urges establishment of many more observing stations. [JH annotation: Routing list to G. B. Airy, George Peacock, and William Whewell.]
Forwards report, just received, of three years of lunar diurnal variation at Cape of Good Hope. [JH annotation: Routing list to G. B. Airy, George Peacock, and William Whewell.]
Will leave London for several weeks when ES's wife is well. Alexander von Humboldt is pleased with English translation of Cosmos. Preparations for magnetic research in Australia, Bavaria, [British] Guiana, and Mauritius. [JH annotation: Routing list to G. B. Airy, George Peacock, and William Whewell.]
Prospects for making magnetic and meteorological observations at Peking, which is more desirable than Shanghai or Hong Kong. Hopes for popular review of subject in Quarterly [Review].
Summarizes for JH the more extensive report appended, which recommends to the R.S.L. and the B.A.A.S. the establishment of magnetic observatories in several Colonial locations.
States his detailed recommendations concerning the continuation, extension, and location of magnetic researches at various locations throughout the world.
Wife not well enough to visit Collingwood. ES may come next week. University of Kasan Observatory may assist British endeavors. Mr. Bolyani is very capable.
Forwards latest computations of lunar diurnal variation in horizontal force of terrestrial magnetism at Cape of Good Hope. Describes method used by Archibald Smith to distinguish lunar from terrestrial magnetism.
Sends copy of ES's reply to Richard Owen, who reported Owen's interview with C. E. Trevelyan. Suggests waiting until summer to apply for government funds to support observatories in Peking and Vancouver Island. ES's recent illness.
Received order for self-recording photographic instruments for magnetic observations from Mr. Bolyani, who plans to improve observatory at University of Kazan. ES quoted prices for making these in London and invited Bolyani to inspect observatory at Kew. ES now prefers Shanghai to Peking as site for observatory. Geographic distribution of global observatories. Reading JH's 'Physical Geography' [1859]. Sends two sunspot photographs from Kew.
Asks permission to include JH on R.S.L. committee, headed by C. J. Selwyn (relative of George Peacock) and Dr. Beale, to purchase portrait of Peacock from artist Douglas Blakiston. Self-recording magnetic instruments have reached Washington safely.
Will assist JH in preparing review of terrestrial magnetism. Progress in publishing vol. 2 of observations from St. Helena. Prince Albert favors new observatories and hopes to see JH [at B.A.A.S. meeting] in Aberdeen. Research in British colonies. Demonstration of Mr. Gossert's apparatus by [T. R.] Robinson.
A. D. Bache reports that self-recording instruments are installed at Washington observatory and ready to begin observations. ES is making field observations to confirm changes in magnetic lines in England since ES's 1837 survey. [JH annotation: Summary of Bache's letter. Joint survey by Smithsonian Institution and U.S. Coast Survey will begin when Bache receives full instructions from Sabine.]
