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.

Note to correct calculations in an earlier letter [see JH's 1869-9-20].
Unable to make any observations at the moment as his observatory is being enlarged to receive his new large telescope. Thinks it would be a good idea to carry out observations on Mercury. Is not sorry to be able to rest his eyes from his trying spectrum experiments.
Burn his [last] letter as he made a blunder in his geometry. Cannot imagine how he made the blunder. Gives new formulae for observing Mercury.
Is much obliged for the more correct determination of Mercury. As soon as he gets his new apparatus he will try to obtain observations of the planet.
Is grateful for his letter. Is also pleased that the proportions between groups of planets and satellites merits his attention. Hopes to forward some tables on sunspots.
Sending tables showing the periodical occurrences of solar spots, earthquakes, volcanic eruptions, etc.; comments on his theories regarding these.
AL claims to be a relative; could JH help financially with the education of AL's sons?
Read JH's letter in the Times with great pleasure. Would like to see the gold question remain as at present. Has not been successful with the Wellingtonia seed; none has come up. Regrets to hear the change in the weather has brought on JH's bronchitis.
Encloses letter regarding coinage under discussion in Parliament.
Sees no likelihood that private meeting would resolve issue between JH and JS. JS misunderstood JH's argument on valuation of British coins and currency. Encloses JS's note to Editor of the Times.
Thanks for catching JH's error. Will write to the Times and substitute 'Mr. Smith, M.P.' for 'Col. Smith.' JH does not understand 'tariff of conversion' or how it will simplify calling in old coins. Prefers 'Binary system' to 'absolutely demonetizing silver.'
Encloses copy of JS's letter to the Times in response to JH's recently published objections to currency system in India. Wishes to meet JH and discuss issue in private, then publish joint statement on subject.
In recent letter to the Times regarding international coinage, JH attributed viewpoint to Col. [J. T.] Smith that was in fact expressed by J. B. Smith, M.P. for Stockport. CW's remarks on valuation of coins.
Still worried about the meaning of some terms in John Herschel's [JH's son] paper [see GS's 1869-7-20].
Agrees with GS's clarification of 'continuous spectra' and other terms [see GS's 1869-9-2]. Includes a copy of part of a letter from John Herschel [JH's son] about solar prominences.
Clarifications of some confusion in the proof copy of a paper by John Herschel [JH's son].
JH having declined offer from Clarendon Press to write a treatise on inductive logic, [Thomas] Fowler of Oxford, who had earlier written a book on deductive logic, drafted an inductive logic, relying heavily of JH's Prelim. Discourse and Familiar Lectures. Asks JH to make suggestions on the manuscript.
Describes celebration of [Alexander von] Humboldt's centennial in Boston. Sends photograph of total eclipse of sun, from Henry Morton, and various other articles. Praises science.
Writes of children's accomplishments. Discusses possible changes in nebula near Eta Argus.
