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.

Is preparing a new edition of his book Le ciel, which J. N. Lockyer is translating into English. Would like to reproduce new information on shooting stars and meteors and would like JH's assistance.

Is happy that his discovery of 70 Ophiuchi was included in JH's catalogue of double stars. Thanks for correction on a logarithm of the focal point equation; intends to change this in Astronomische Nachrichten.
Thanks for the additional information regarding Argus by Elias Loomis and J. Tebbutt; it will appear in the next R.A.S.M.N.

J.] Chevigné was stopped. Failure of gold standard in India. French and English coins. Suggestions on WJH's effort to introduce oaths into Indian justice system. Popularity of velocipedes [bicycles]. Family news.
Has read the syllabus of GA's lectures on magnetism; it reminds JH of his attempt to solve the problem of 'Mahomet's coffin', which JH still believes would work.
