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.
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.
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.
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.
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.
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.
Encloses letter from G. B. Airy. Suggests new method of magnetic observation.
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.
Presents data on various disturbances. Awaits advice from C. F. Gauss. Discusses determination of intervals between observations. Mentions proposal to continue observations for 3 years.
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.
Advice for standardizing observations, to be given to the Physical Committee of the R.S.L.
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.
On discrepancy of data from G. B. Airy and Humphrey Lloyd. Captain Boileau and John Caldecott exchange instruments to normalize data. Will send letters from Airy, [A. T.] Kupffer, Lloyd, ES, and JH to John Lubbock and the R.S.L. Council concerning the discrepancies.
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.
Congratulates JH on his latest child. Notes that data from James Ross show great disturbances at the Kerguelen station simultaneously with Toronto and Greenwich. Has sent various data to C. F. Gauss. Wilhelm Weber reports a new magnetic station at Havana recording by the British system. Notes Ross's dip data supports Gauss's theoretical expectations.
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 plans for publishing magnetic storm data. Mentions transportable magnetic instruments and their use for a travelling observatory on an expedition to the Falkland Islands.
Norwegian government plans to support a magnetic observatory. Discusses details concerning R.S.L. logistical support and sources for instruments and training. Encloses Wilhelm Weber's letter concerning the instruments. Notes Charles Riddell's return and Lieutenant Younghusband's continued good work.
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.
