The Sir John Herschel Collection
The preparation of the print Calendar of the Correspondence of Sir John Herschel (Michael J. Crowe ed., David R. Dyck and James J. Kevin assoc. eds, Cambridge, England: Cambridge Univ. Press, 1998, viii + 828 pp) which was funded by the National Science Foundation, took ten years. It was accomplished by a team of seventeen professors, visiting scholars, graduate students, advanced undergraduates, and staff working at the University of Notre Dame.
The first online version of Calendar was created in 2009 by Dr Marvin Bolt and Steven Lucy, working at the Webster Institute of the Adler Planetarium, and it is that data that has now been reformatted for incorporation into Ɛpsilon.
Further information about Herschel, his correspondence, and the editorial method is available online here: http://historydb.adlerplanetarium.org/herschel/?p=intro
No texts of Herschel’s letters are currently available through Ɛpsilon.
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.
J. H. Lefroy returned from McKenzie River [Canada] having established at least 350 magnetic stations between there and Red River, 'a fine pendant for [J. C.] Ross's survey' in southern hemisphere.' If expedition continues through winter, it will provide excellent survey of North American disturbances.
Sent out copies of JH's remarks on Toronto actinometer. Expects that observations recommended by JH will be made next summer. Replacement for J. H. Kay's broken actinometer will arrive [in Tasmania] next June. Possible remedies to declination readings.
Francis Baily contracted with RT to print N. L. Lacaille's catalog of stars and J. J. L. Lalande's Histoire céleste. Account was suspended after Baily's death until B.A.A.S. meeting in York approved its continuation. Requests £300 from JH, chairman of grant committee.
Sends JH a letter from Thomas Maclear, in line with Francis Beaufort's instructions.
Sends TT some specimens of the plant tritonia uvaria.
A note of thanks upon receipt of the thirteenth volume of the observations of the Cambridge Observatory.
Describes activities at Charles Pritchard's school, including lessons in botany. Also reports that one fellow student is very ill.
