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.
Believes he has discovered a second satellite of Neptune; gives readings.
Sends on announcement of 'new planet Parthenope' from Annibal de Gasparis at Naples.
Is just leaving for France, and has time only for a few thoughts in response to GA's 1850-8-18.
Will be very busy learning his new job for a while, so GA should start working with other committee members; JH makes some suggestions about eclipse observation [see GA's 1850-12-14].
A note accompanying a letter that seems to come from François Arago, and that seems to JH to show a disturbed state of mind; asks GA for his opinion.
Asks GA for help in identifying an astronomer for the observatory at Trivandrum, India.
Thanks GA for his 1850-4-1, and provides details of a likely candidate.
