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.

Wrote to JC's brother-in-law, H. T. Prinsep, who promised that JH's 'nephew' will receive direct appointment when nephew comes of age. Gratitude for JH's friendship of 14 years. JC's husband is in Ceylon. Invites JH and wife to visit JC. Names other recent visitors.
Observed increased breadth of Saturn's ring on 25 and 29 Nov. 1850, confirmed by William Lassell on 3 Dec. Independent discovery of inner ring at Harvard University on 15 Nov. was announced in the Times on 3 Dec. Sent WD's notes to R.A.S. to establish independent discovery, but R.A.S.M.N. reported this erroneously.
Is very appreciative of JH's letter of condolence at the death of H. C. Schumacher; also clarifies how Schumacher's responsibilities are being carried out.
Gold from America is not identified by its local source, so quantity of California gold can only be estimated. Contact W. D. Haggard or Matthew Marshall for information.
Happy to assist JH in researching fluctuations in global supplies of gold and silver. Lists sources of information.
Needs to know how much gold from California has entered England.
Asks that JC hold JH excused from appearing tomorrow, because JH has a severe cold.
Wishes WD had heeded JH's advice [in JH's 1851-1-18] regarding report of WD's discovery to R.A.S. Description of Saturn's inner ring.
Does not believe JH can help RH in some delicate matter. JH talks about photographic chemistry, including passing on information from A. C. Becquerel.
Receives workload from H. D. Harness. Discusses the striking of the commemorative Waterloo Medal.
Will continue to write in Italian so JH can censor the translation of the letters when giving information to other officials at the Mint.
Sends information on imported California gold as JH requested.
Gave permission for F. M. Russell [wife of prime minister] to tour Mint on 30 Jan. Do not be concerned over Benedetto Pistrucci's remarks; JH's note accompanying Pistrucci's letter will be sufficient for Treasury to understand the situation. P.S.: Suggests letting Lady Russell see studio of [William] Wyon.
Letter from Benedetto Pistrucci incorrectly quotes JH as stating that no Mint officer except Pistrucci is capable of handling dies. W. T. Brande may interpret this as lack of JH's confidence in Brande's abilities.
Sent papers to Mint in response to JH's questions. Will soon send information on circulation of Bank of France.
Asks JH and H. D. Harness to meet CW on Monday.
Sends 1849-50 silver prices.
Wants BP's opinion on the number of casts that should be made for medal.
Two books arrived for the Mint library. When are JH and HH scheduled to visit Chancellor of Exchequer [Charles Wood]?
