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.
Encloses transcript of letter dealing with object-glasses. Has given notice that he has withdrawn from the Physical Committee of the R.S.L.
Gives reasons why telescope for Cape Observatory should be as perfect as possible. Doubts that its 'finder' is adequate.
Hopes JH will be staying with him. Would like statement from JH regarding the Magnetic Observatory.

Arranging a meeting of the Magnetic Committee to set the agenda for the magnetic conference to be held during the B.A.A.S. meetings in Cambridge.
Asking him to arrange distribution of the R.A.S. catalogues as he is too busy. When is JH going to try William Simm's object planes?
No news yet about the request to Robert Peel for money for magnetic observations.
Encloses a copy of JH's 'letter of conditions.' Has been extremely busy.

Robert Peel has suggested that the Admiralty has money available to pay for improvements in scientific instruments of value to navigation.
Encourages GA to ask the Admiralty about the implications of Robert Peel's statements [see JH's 1845-9-29 or earlier].
Asks for new observational data on Gamma Virginis [see JH's 1843-7-18].
