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.
Informs JH that his comments against sending a major telescope to India were decisive [see JH's 1866-8-11 & 1866-9-4]; biggest cost impediment was salary of observer.
In response to ES's 1866-12-6, JH sees no benefit in a great equatorial telescope in India being an itinerant instrument.
Comments on the state of William Whewell's health, and about the theories of E. F. W. Klinkerfüss [see JH's 1866-2-27].
Asks JH to recommend a reviewer for a popular book on astronomy.
Thanks JH for recommendation [see GS's 1866-3-2].
Declines to be involved in another [scientific ?] undertaking, as JH's health is too precarious.
Is sending WH papers and material on weights and measures. Proceeds to argue strongly against any introduction of the metric system into India.

Trying to ascertain the time for the eclipse of Jupiter's satellites. Wants to know the proper correction for his own telescope.
Sends observations of circumpolar nebulae originally published in the Astronomische Nachrichten. Hopes calculating their motion will eventually be possible. Wants JH's opinion on GR's work.
Asks JH to give 2 or 3 lectures on astronomy in the upcoming course at his school. JH declines the offer in an attached draft of a response.
Sends observations of additional circumpolar nebulae. Notes differences between his observations and those of JH. Hopes to determine positions of very faint nebulae in the future.
Comments on the quality of the star catalogue of Charles Rümker [see John Wrottesley's 1866-4-16].
Criticizes Charles Rümker's catalogue of southern stars.
Need to meet to discuss the question of publishing Charles Rümker's star catalogue [see JH's 1866-4-20].
