Urged by G. B. Airy, ES withdraws earlier letter to JH and encloses letter with ES's opinions regarding continuance of [magnetic and meteorological] observations.

Asks JH to inspect first magnetic and meteorological observations from [Tasmania] and Toronto. Hopes North American observations will be increased.

Will send JH's report to JH in August. J. C. Ross will not be at Cork meeting, but JH may announce there that first year of Ross's observations at sea will appear in R.S.P.T.

Forwarded letters to William Whewell, as JH requested. Will show copies of them to G. B. Airy. Completing volume of J. C. Ross's second crossing. Willing to take charge of W. R. Birt's models.

Payment for instruments sent to Breslau observatory. Received proofs of JH's paper, which does justice to Humphrey Lloyd. Spoke to Lord Melbourne about establishing a magnetical and meteorological observatory in vicinity of London. Compares expenses for permanent and temporary observatories.

Encloses bill from W. H. Allen & Co. regarding Breslau observatory. [JH annotation: Details of bill.]

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.

Received letter from J. H. Lefroy in Athabasca [Canada]. Extract of C. J. B. Riddell's winter magnetic operations and summer plans along Red River.
