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.
Supplement to JH's report [see JH's 1845-10-10] on object glasses for Cape Observatory. Different results at lower powers when observing planets.
Thanks JH for his report on William Simms's object glass trials [see GA's 1845-9-29], together with some other astronomical matters, including reference to a letter from F. W. Bessel.
Wants JH to write the communication to Sir Robert Peel regarding the science conference. Foreign members are particularly anxious that JH do this.
