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.
Has heard about William Whewell's accident. Hopes he will recover, but knows his advanced age may hinder this. Wishes WS to send news of progress.
Thinks William Whewell's excitement may be a 'precursor to exhaustion.' The hope of recovery is very slight. JH is interested in Whewell's article on Plato.
Thanks WS for communicating the events of William Whewell's last days.
Discusses how to denote the positions of the celestial bodies in solar photographs. Advocates a system that shows differences of heliocentric longitude on the sides of the sun.
Helioautographs are beautiful. Advises keeping original plan for presentation. Says 'Clarke's' [Harvey Carlisle's] article on William Whewell in MacMillan's is satisfactory. Describes an 'absurd paragraph' regarding Whewell in François Moigno's Mondes.
Says the plan for the exhibition is ingenious. Discusses the 11 year cycle of sunspots and says the sun was spotless the previous day.
Congratulates WS on his recovery. Thanks him for the meteor observations. The evidence points to an 11 rather than a 10 year period [in sunspots?].
