Comments on the operational and organizational details of the magnetic and meteorological observatories, and on the supervisory committee's [the Physical Committee of the R.S.L.] responsibilities.
Insists on inclusion of all data and graphs in the publication of the accumulated magnetic observations, made as part of 'perhaps the very greatest scientific operation ... ever ... undertaken....' Urges that funding be sought from the government.
Provides examples to justify governmental support of various magnetic and meteorological observations. States that 'Terrestrial magnetism ... of all sciences of observation holds out the greatest present prospect of decisive reduction under ... exact theory.' Mentions work by N. L. Lacaille and Thomas Maclear at the Cape.
Advice for standardizing observations, to be given to the Physical Committee of the R.S.L.
Encloses letter on and discusses extent of government aid for proposed Hammerfest magnetic observatory and various alternatives with regard to it.
Sends [James Clark] Ross's journal and revised B.A.A.S. magnetic report. Discusses proposals for observation in Africa. ES will send various instruments to Africa.
Sends letter from [A. T.] Kupffer regarding magnetic observations. Discusses Great Toronto Disturbance of 18 November and observation of it at Greenwich, St. Helena, and St. Petersburg.
Thinks enclosed letter should be appended to [James] Farquharson's report on aurora. Wants to bring magnetometer to Alford. Hopes JH has [Humphrey] Lloyd's article regarding instruments.
Discusses proposed temperature experiments involving balloons. Prince Edward Island would be good observatory but funds are lacking. [C. F.] Gauss's article translated for Scientific Memoirs.
Wants JH to include [J. C.] Ross's instructions in his forthcoming report. Encloses tract on station errors. Discusses [Elias] Loomis's findings regarding errors in measurement.
Will be happy to send particulars from [C. F.] Gauss's information. [Humphrey] Lloyd's instrument records changes in horizontal intensity best. Wants to employ magnetometers in New York.
Corrects information from an earlier letter. [John] Caldecott stated that diurnal curve of declination changed with monsoon at Trivandum. Discusses [William] Allen and observation with transportable magnetometer.
Sends JH some actinometer observations and a letter from G. B. Airy to forward to Humphrey Lloyd. Also some observations of shooting stars made by [James] Farquharson.
Discusses problem involving JH, George Peacock, Humphrey Lloyd, and Wilhelm Weber regarding the price of magnetometers. Also mentions reports of magnetic observations in Russia and at the Cape of Good Hope.
Asks JH's advice on the publication of various observations. Is also awaiting advice from Humphrey Lloyd.
Relates Humphrey Lloyd's complaint that JH sent Mr. Meyerstein's letter by mistake. Asks JH to forward [A. T.] Kupffer's letter along with those enclosed from Charles Riddell on the magnetism survey in America. Asks for JH's advice on the publication of the observations.
Assures JH that he will publish magnetic observations as JH desires. [Hussey] Vivian awaits the estimate of cost of publication. Encloses circular sent to the British magnetic observatories. Informs JH that the Niger and Guiana magnetometers have arrived safely. They should provide interesting comparisons with other observatories.
Has learned of the availability of a house at Kew, which could be used as a magnetic and meteorological observatory. Dr. Robinson has received the instruments.
Francis Beaufort will send JH sheets from James Ross covering trip from the Cape to Van Diemen's Land. Laments Charles Riddell's leave of absence but acknowledges replacement Lieutenant Younghusband's skill. States that C. F. Gauss has informed him by letter of the location of the south magnetic pole. Informs of [Edward] Belcher's letter concerning various magnetic stations in the South Pacific.
