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 gift of flower roots; she will take great care of them on her arrival at Sydney.
Is pleased to hear the Herschels are contemplating their return but regrets it will not be via Rio. J. D. Forbes is progressing well, may be in danger of overwork. Thomas Henderson too is doing good work at the Observatory. Gives results of lunar eclipses of Oct. 1837.
The zenith sector was brought by the Wellesley and is now at the Observatory. Outlines some observations he hopes to make with it. Is about to write to R. Thom[p]son. Has some important matters to discuss with JH when he calls.
Thanks for the interesting account of the star whose variability has now been established. Used the 3 1/2 foot last night and definition was good. Returns JH's letter to [James?] Dunlop and thinks there should be no offense taken. Opening for the Zenith is being enlarged. Measured JH's azimuth East and West yesterday.
Thanks for the perusal of Capt. J. A. Lloyd's papers. Comments on Lloyd's work at Mauritius. Does not think a mural circle necessary for the observatory at Mauritius. Regarding the Parade base line at the Cape. Not easy to put the guns into the ground.
Availed himself of the calm weather to finish the parade measurement. Gives an account of the work.
Talks about the very hot weather, and some matters of business that JH needs to work out with TM.
About the remarkably bright variable star, Eta Argus.
Some minor matters of astronomical business followed by an extended list of principles on which a constellation reform might be undertaken.
Describes his observational activities, especially the discovery of the variable nature of Eta Argo, and the rediscovery of the sixth satellite of Saturn.
JH's observations disagree with JD's 'Catalogues of Nebulae and Double Stars' [observed at Paramatta, Australia]. Believes errors lie in JD's work. Will send copy of JH's catalogue as soon as it is printed. [8pp of notes extracted by JH from JD's catalog; 7 pp of JH's comments, written in another hand, about these notes.]
More about lack of success of exhibition, and about publication of observations [see AS's 1837-8-27].
Observations regarding the nebulous star 1281.
Is sending him a letter of Basil Hall. William Whewell is preparing another paper on the tides and is hoping for data from JH when he returns. Hears that JH will be home in June. Looks forward to seeing him again.
Gives latitude of 'this observatory' used in reduction of 'Comet stars.' Will accept systematic correction in all data to compensate for differences between TM's and Thomas Henderson's data. Instruments are erratic since telescope was moved. Using transit instrument only for sun, planets, and [reduction of Thomas] Brisbane's stars.
Intricate enquiries at Paramatta observatory are a waste of time. Instruments are not first class. Energy would be better spent cataloguing smaller magnitude stars and measuring double stars. Urges triangulation survey, important for Asian and Pacific geography, and investigation of weights and measures, to avoid litigation as Australia develops.
Reports observations of the 'remarkable' increase in magnitude of the 'nebulous' star Eta Argus.
Reports observations of the 'remarkable' increase in magnitude of the 'nebulous' star Eta Argus.
An extended statement of the importance of the observatory at Parramatta, Australia.
