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.
The continuation of magnetic and meteorological observatories is under question, and CW's instrument for observing atmospheric electricity should be part of the discussion.
Makes some amendments in JH's request for information [see JH's 1845-4-6].
Wants to know if GA's opinions [see GA's 1845-4-1] are available for public information, or only for JH.
Is very critical of a series of three foreign memoirs that JH believes certainly should not be published. Concludes with a strange postscript on catalepsy.
Responds to recently printed letter by James South. Denies South's assertion and confirms that William Herschel did discover two interior satellites of Saturn with 40-feet reflector telescope in 1789.
Privately acknowledges lack of clarity in William Herschel's report of discovering Saturn's inner rings, but JH was hurt by James South's public refutation of that discovery and by [T. R.] Robinson's abrupt refusal to communicate. Reviews WH's papers to demonstrate falsity of South's claim. Asks TM's opinion.
About a letter of recommendation JH is preparing for Robert Hunt.
Seeks GA's assistance in solving a puzzle in the mathematics of rotating bodies.
[Robert Chambers's] Vestiges of Creation is shallow and full of errors. Tells AS not to spare it when he reviews it. Discusses various topics including the nebular hypothesis, P. S. Laplace, central heat in gravitation, and the density of planets. Also, the 'nonsensical calculations' of Auguste Comte's astronomy.
Discusses procedures that should be followed when the Committee on Physics is summoned to deal with a 'momentous' matter, i.e., the discontinuation of the magnetic observatories.
On Francis Baily's titles and on how to get a print with Baily's picture, autograph, and name in regular capitals. Explains remarks he made in a controversy with T. R. Robinson and published in the Athenaeum [Autumn, 1843] about JH's father's telescopes.
Provides the best values available for dispersion and separation, which will allow GA to calculate what he needs [see GA's 1845-4-4].
Expresses his pleasure at RH's new position at the Museum of Economic Geology.
Sends P. H. L. Boguslawski's address. Asks WS to send J. H. Mädler's chart to P[eter] Stewart.
Regarding the deed for CB's brother-in-law. Is reading G. W. Leibniz's metaphysical works.
Mostly about the health of JH and his wife, Margaret.
CG having now received the Greenwich and Toronto observations, JH invites CG to write further material for the forthcoming publication.
