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 grateful for his comments on his own theories regarding the flat 7th as a harmonic. Enlarges on this theme.
Invites the Somervilles to dinner the following week.
Is preparing to observe the occultation of Aldebaran. Seeks JH's comments on GP's position on the perturbations of Jupiter and Saturn compared to P. S. Laplace's work on the same subject. Comments further on the sending and receiving of packages of memoirs.
Is sending papers for the Astronomical Society Memoirs, on telescope lenses and the construction of telescopes, planetary observations, and the use of equatorial telescopes. Is anxious to see JH's writings on light and his nebulae catalogue.
Wants JH to return the last 8-10 pages of her manuscript. She wishes to correct and improve it.
If Margaret Brodie Herschel is too ill, do not travel to London for MPH's sake. Will send Mrs. Moorsom to Slough.
