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.

Regrets a week has elapsed before replying to her letter, but is pleased that Miss Mathilde Oersted had so high a regard for his speech concerning her illustrious father.
Thanks for RJ's 'unwearied vigour and activity of mind.'
Replies to several queries about papers of JH. JH describes the accidental production of some interesting copper salt crystals.

Is willing to assist in obtaining letters of introduction for WL's projected trip to Malta.
Points out deviations from policies recommended in 1848 by Mint Commission. Supports consolidation of supervisory positions. Protests C. E. Trevelyan's idea that JH's scientific pursuits in spare time as Master of Mint must be directed to public projects.
Is concerned about the possibility that the observatory at Altona will be discontinued or moved.
The balances in the Mint are not adequate for the work WM wants to do.
Identifies WM as a committee member for the R.S.L.; raises the question of standard weights in relation to weighing gold bullion.
Asks GP to participate in the marriage ceremony of JH's daughter Caroline.
Suggestions and diagrams for projecting sound great distances by means of small arms and parabolic reflectors.
RB's certificates were issued in 1825 by now-abolished Mint Board. Explains reorganized administration of Mint.
[Marked 'Private.'] JH found passage in Treasury's letter to Benedetto Pistrucci that could contradict the denial by Lord Maryborough [William Wellesley-Pole] of Pistrucci 's claim to lifetime job and salary at Mint.
[Marked 'Private.'] Found written evidence of the denial in 1825 by Lord Maryborough [William Wellesley-Pole] of lifetime tenure at Mint for Benedetto Pistrucci. Suggests contacting [W. R.] Hamilton for clarification.
Returns letter from C. E. Trevelyan. Awaits final conclusion in difficult case of Benedetto Pistrucci.
Moneyer's former policy has resulted in two pay scales for Mint employees. Asks help in standardizing pay scale. Repair cost for air pump may be double original estimate. Treasury rejected JH's appeal on behalf of F. R. Brande; plans to appeal to Chancellor of Exchequer.
Instructions for assaying Indian coins.
JH made clear on 13 Mar. that HF's position in reorganized Mint would be that of newly entering junior clerk and that F. R. Brande's position warranted more seniority.
Will give every consideration to case of Benedetto Pistrucci, but Engraving department is long overdue for changes to bring it into conformity with all other departments in reorganized Mint.
