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].

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.]

Does JH wish to alter ES's reply to A. D. Bache? Origins of names for American rivers. Hopes JH is well enough to accept the invitation of Lord Aberdeen [G. Hamilton-Gordon].

Replied to J. A. da Silva that Kew Observatory would gladly train Portuguese observers and superintend manufacture of instruments, but that ES could not speak for English government. [JH annotation: Summary of letter from da Silva, director of meteorological observatory in Lisbon, requesting training for Portuguese observers at Kew, British influence on Portuguese government to join magnetic survey, and advice on instruments.]

Notified Richard Owen that Kew observatory is ready to receive trainees for magnetic observations. Stewart Balfour estimates six weeks to train observers, who will then take instruments and leave for British Columbia or Shanghai. New observatory at University of Mississippi in U.S. American Association for the Advancement of Science has expressed interest in magnetic survey. Success in photographing sunspots, which R. C. Carrington and Warren de La Rue will supervise. Recent observations.

Encloses ES's résumé of magnetic surveys accomplished by U.K., written to encourage similar surveys in China and North America. Perhaps JH may append this to JH's report.

Proper procedure for communicating with Charles Grey. Cost and effectiveness of self-registering instruments versus older visual instruments. ES's method of estimating observatory expenses. Importance of observatory in Shanghai.

Extract of letter from Charles Grey, asking B.A.A.S. to inform Prince Albert of estimated expenses for proposed five-year survey of terrestrial magnetism. As president of joint committee of B.A.A.S. and R.S.L., JH should answer this. Entry of three U.S. observatories may eliminate need for observatory in Newfoundland. Recent visit to Kew by A. T. Kupffer suggests that Russian stations may soon have self-recording instruments. Proposes suspending observatory in Falkland Islands until colonies decide to join survey. Dutch observatory in Java. Describes buildings needed for observatories. Estimates expenses for six years.

Sent proof for vol. 2 of St. Helena observations to JH. JH's promised article in Edinburgh Review on progress in science of terrestrial magnetism. Embarrassing delay by government in responding to Prince Albert's request for five-year magnetic survey is resulting in loss of interest among prospective directors. Proposal by Americans to assume leadership of survey in North America. Dutch observatory in Java and Jesuit observatory in Cuba.

A. D. Bache reports that U.S. will establish magnetic observatory in Washington Territory. ES is preparing instructions for North American survey. Suggests change to JH's proposed article on terrestrial magnetism in Edinburgh Review.

[Government refusal to support five-year magnetic survey] has eliminated services of T. W. Blakiston and Thomas Hull as directors of two magnetic observatories. Instruments for Montreal observatory. Recent magnetic changes in North America. Success of elder B. C. Brodie's eye operation.
