Approves of proposal by A. T. Kupffer and Edward Sabine for international magnetic congress under JH's leadership. [Reply to JH's 1844-7-22 to HL.]
Approves of proposal by A. T. Kupffer and Edward Sabine for international magnetic congress under JH's leadership. [Reply to JH's 1844-7-22 to HL.]
As secretary of Wernerian Club, CM requests information from JH on atmospheres of moon and planets.
Agrees to host congress at Cambridge to assess data from [magnetic and meteorological] observations. Suggests adding D. F. J. Arago to list. Will include this in GP's address to B.A.A.S at York. [JH annotation: List of five members.]
GP prefers to meet on Saturday at Somerset House, rather than on Friday as JH proposed.
JH appointed to a committee with G. B. Airy and William Stratford on the reduction of the calculations of N. L. Lacaille's stars.
JH, William Whewell, George Peacock, Humphrey Lloyd, and Edward Sabine are appointed by the B.A.A.S. to study systems of simultaneous magnetical and meteorological observations. They will be granted £50.
Funding for magnetic and meteorological instruments for Ceylon, which would be valuable addition to H.E.I.C. observatories. Compares [barometric] curves from America and Europe. Magnetometers for [Nossrey?] were paid for out of R.S.L.'s Donation Fund.
B.A.A.S. should not assume publication of meteorological observations if L. A. J. Quetelet gives these up. Johann Lamont in Munich is better qualified. Received from John Caldecott five years of meteorological observations at Trevandrum [India]. George Peacock has invited B.A.A.S. to meet at Cambridge in 1845.
Add to [ES's] enclosed letter, which ES will explain more fully at committee meeting next week.
Colonial governor at Ceylon will grant £150 annually for operation of magnetic observatory at Colombo, directed by Royal Artillery officers already there, if [R.S.L.] will supply instruments. Proposes seeking money for instruments from Wollaston Fund.
Appropriate use of Wollaston Fund for supporting research. Possible sources of instruments for new magnetic and meteorological observatory at St. John's, Newfoundland.
A. T. Kupffer proposes international meeting of authorities in terrestrial magnetism. ES suggests combining this with 1845 meeting of B.A.A.S. at Cambridge. Plans for publishing observations before Cambridge meeting.
Ship is ordered for Lt. Clark's excursion. Feels certain that Lord Stanley has consulted colonial governor.
JH is premature in concluding that international meeting of magnetic researchers would result in appeal to British government for funds to continue B.A.A.S. observatories beyond 1845. ES has not reviewed later observations [1842-43] and cannot judge whether observations have met original goals of R.S.L. and B.A.A.S. Agreement by Robert Peel and F. I. Brunnov on need for longer period of observations. Affirms value of JH's role in evaluating results of survey.
ES agreed to superintend publication of magnetic observations only because Humphrey Lloyd refused to do so any further. Format intended for each volume. Gratitude for JH's contributions to magnetic research. [P.S.: Provision of instruments to U.S. observers.]
Informed A. T. Kupffer that JH will preside at 1845 B.A.A.S. meeting and invited Kupffer to attend. Activities of [James] Renwick and A. D. Bache in trigonometrical survey of U.S.
Let George Peacock take care of inviting foreign magnetic researchers to B.A.A.S meeting at Cambridge. ES could prepare report on results of British government observatories by next February.
Sends copy of ES's memorandum to George Peacock describing progress in publication of magnetic and meteorological observations. Encloses copies of observations from Antarctic survey and Ceylon. Reasons for H.E.I.C.'s hesitation to expand survey by C. M. Elliott. Praises C. J. B. Riddell's book, which described portable magnetic apparatus that is now requested by observers worldwide. Recent changes in other instruments. Reimbursement for instruments provided to observatory in Newfoundland. Recent results of surveys on Continent, in Canada, and by Capt. Blackwood in Torres Straits.
Forwarded to George Peacock JH's letter of 11 Sept. Karl Kreil will send self-registering instruments that ES ordered for Kew observatory. Influence of vapor pressure on barometer readings. Introduction of hygrometers.
George Peacock returned JH's papers, with letter by Peacock. ES forwards these to JH.
