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.
Congratulates him on his discovery of the parallax of Alpha Centauri. Comments on this and makes suggestions for further examination.
Declines to review WC's recent work, and then JH justifies his position for the rest of the letter.
On RM's stepping down as president of Geological Society. Where exactly abroad will RM pursue enquiries?

Is confident that by summer his sweeps will all be reduced and arranged in three catalogs for JH's Cape Results.
Thanks GA for exercising GA's usual discretion in the matter of the funding of Charles Babbage's calculating machine [see GA's 1842-9-26].
