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.
EW and daughter look forward to visiting Slough on Monday with Mr. Beckwith.
Needs the Ephemerides for 1769. Can he ask [James?] Graham[e] for any old pamphlets. Is expecting William Whewell and George Peacock and would be glad if JH can come as well.
Received JH's letter [29 Apr. 1821] with 'Memoirs of Astronomical Society' and observations of recent solar eclipse. Has not published eclipse calculations. Convinced that moon's diameter is accurately determined. Latitudes, longitudes for sites in Finland. 1820-22 observations from Ã…bo. Design of new Ã…bo observatory. New instruments from Munich.
Encloses list of books on Ireland as requested. Her brother is in London. Hopes that JH will visit them should he come to Ireland.
Regarding the construction of the model machine. Things appertaining to the Netherlands. Regarding his new chemical theory.
Has no errands for JH in Holland or Flanders. Asks for details on JH's and Charles Babbage's method of determining heights by barometrical observations. Hopes to use this to confirm TY's method by 'my formula deduced from refraction.'
Received JH's letter from Calais. Visitors to Slough. Marquess of Londonderry committed suicide.
William Herschel is dangerously ill. Hurry home.
Books per N. M. Rothschild have not yet arrived. Has arranged a standing order for the Vienna Observations. The Robert Molyneux clock can be dispatched at once. Agrees with JH that double stars are the test of a good telescope.
William Herschel is getting weaker, but is not in pain. Lady Mary Herschel is anxious for JH's arrival.
Invitation to JH to meet some friends of AL's.
