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.

Sends to HL a sheet of curves laid down by [Charles] Riddell, comparing Brussels declination observations with those made in Toronto. JH frequently refers to HL's work on the subject of terrestrial magnetism.
Recommends printing all three papers sent to JH—G. B. Airy's on spectral bands, [Robert] Hunt's on influence of iodine on photographic papers, and that by Lord Oxmantown [William Parsons] on large reflecting telescopes.
Believes that R.S.L.'s request for £3000 grant to establish permanent magnetic and meteorological observatory is too hasty. Urges caution. Points out potential problems.
R.S.L. will deviate from its intellectual purpose whenever it meddles in practical observations. Proper role for R.S.L. is to suggest goals and methods and to reward discoveries. Recommends discontinuing meteorological observations at Somerset House; other stations now provide better data. If R.S.L. insists on establishing a meteorological register, JH suggests one like that of J. F. Daniell.
In light of minutes of R.S.L. Council meeting, outlines vision of permanent national physical observatory and, more importantly, an experimental institute or college. Hopes Edward Sabine will be interested.
Invitation to Hawkhurst. Has plenty of R.S.L. work to keep him from his observational work. Question of a new observatory. Has had letter from Wilhelm Struve regarding the fifteen-inch object glass.
Thanks AD for a correction in one of JH's writings; tries to explain the partial echo that occurs when blowing across the end of an open pipe.
Has no objection to the recipient's republication of the 'Examples of the Differ. & Integl Calculus by Mr. Peacock,' to which JH contributed.
Praises various photographs by WT and notes changes in some. Recounts optical experiments, recent and planned, by JH on rock-salt.
Gives JH's new address in Hawkhurst. Bring Mr. Bunt's planetarium when WW comes to Hawkhurst. Announces new photographic results.
