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.
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.
Forwards request of the Secretary of the Treasury for justification of public monies for expenses incurred for magnetic and meteorological observations of the Antarctic expedition. Brief note from JH should suffice for House approval. Note should mention G. B. Airy's request concerning the reduction of the Greenwich lunar and planetary observations and Francis Beaufort's concerning navigation. ES promoted to Lieutenant Colonel.
Quotes passage from C. E. Trevelyan (Treasury Office) to [Hussey] Vivian concerning the number of copies of published data and the number of magnetic observatories. Requests JH's perusal and advice. Includes letter from [A. T.] Kupffer on latest observations.
Relates discussion with [Hussey] Vivian on magnetic survey of Africa and Treasury support thereof. Discusses administration of various stations.
Discusses the reductions and publication of magnetic observations from various stations. Describes report of the Antarctic expedition and the determination of the magnetic pole. Endorses proposal for Canadian Survey. Discusses survey of South Africa and British Guiana.
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.
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.
No summary available.
Expresses his approval of James Ross's Antarctic survey, providing some of the details of it and his determination of the south magnetic pole. Gives details of Ross's plans.
Mentions a deletion of part of James Ross's dispatch. Clerk is receiving instructions from Charles Riddell before sailing to the Cape of Good Hope, from which observatory he expects a report in eight months. Asks whether the R.S.L. should request government funding for Cape observations and experiments. Wonders if astronomical and magnetic observers there could assist each other. Requests information on the atmosphere.
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.
Speculation about land masses and climate in Arctic regions. Extols James Ross's talents. Discusses John Dalton's pension and who should be devoting efforts for approving pensions.
