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.

Refers to a variety of salts and their reaction to light in the production of photographs. JH hopes that [?] still intends to publish his work in this area.
Finds GA's measurements of Gamma Virginis far away from JH's own, and instructs GA in the best way to measure double star positions.
Devises and suggests mode of micrometric measurement of angles.
Sends calculations of Gamma Virginis and determines its eccentricity. Believes the orbit is highly elongated, like that of a comet.
Has received the maps. Gives F. W. Bessel's views on the re-arrangement of the constellations which has been proposed. Comments on FB's memorandum.
Comments on calculation of orbit of Gamma Virginis; requests any observations EC has of that star.
Received copies of barometer observations. Searching for original data (lists stations) that JH sent to WB. Invites additions to JH's report. Please send account of expenses.
Yesterday's letter was mistakenly sent to WB's former address. Sends copy.
JH's theory of barometric waves. Comparison with ocean tides. Non-trade winds follow laws of periodicity and are predictable, accounting for previously unexplained phenomena. Attributes rotating storms to interference of two or more wave trains. Will propose WB as director of new B.A.A.S. project to discover laws of weather behavior. Sends payment for WB's expenses. Never saw anything more beautiful than WB's 'Symmetrical Barometric Curve.'
Declines WP's invitation to attend Cork B.A.A.S. meeting and afterwards to visit WP and to see his reflecting telescopes. Informs WP that [C. A. von] Steinheil had written JH about a process of 'Electro-gilding' mirrors for telescopes.
