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.

Did not contemplate gratuitous contributions from JH.
Regarding JH's comments on a paper of Francis Abbott read at the R.A.S.'s meeting on 12 June. Believes the paragraph in question came from a paper of Sir William Herschel. Understands that Lieut. John Herschel has just examined this nebula.
Is preparing a sketch of Sir John Lubbock for a weekly, and would be glad of JH's opinion regarding Lubbock as a man of science and his advanced political views.
Can he publish JH's statement regarding John Lubbock? Outlines the wishes of other scientists regarding the printing of their views.
Sending his impression, formed during a recent visit to Dublin, of the Great Telescope destined for Melbourne. Considers it a triumph of mechanical invention.
The Archbishop [of Canterbury, C. T. Longley] will be lunching with EL on the 24th and if JH is able will he join them for lunch.
Much obliged for calling his attention to M. C. E. Du Four's paper, though he cannot reconcile the general reasoning. Comments on the effect of the Sirocco on the Föhn of the Alps.
Sends Captain [P. F.] Shortland's account of his recent soundings and temperatures of the sea. Comments on these readings in the light of theory. What does JH think of the matter.
Has read with great interest JH's paper on the musical scales. Comments on JH's paper and expounds some of his own theories on the musical scales. Would like JH's comments on his paper.
Appreciates JH's beautiful simplification of the numerals in musical arithmetic. Wishes JH would give up the point of the variability of the supertonic and transfer it to the submediant. Agrees with JH over the need for a keyboard instrument possessing a perfect chromatic scale in any particular key.
Comments on double star observations and some papers on the subject.
About the location of several different sets of double star observations.
Comments on the quality of some of the double star observations in print.
Forwards a drawing of the great nebula of Orion, which he has just received from Angelo Secchi for JH. Quotes Secchi's remarks.
Thanks for his communication regarding the reported changes in Eta Argus, and also Lieut. John Herschel's letter from Bangalore. These will form a valuable addition to the next R.A.S.M.N.
While in Switzerland requested his wife to send to JH a little tract on Count de S. Robert's hypsometrical investigations. Found that Robert's formulae worked correctly for ordinary European heights. Realizes that JH demolished Robert's theories, but Robert also showed observations on P. S. Laplace's theories.
Tyndall wishes to resign his lectureship at the Royal Institution. If Alexander [Herschel] would like this position, RM can recommend his appointment to the Governors.
Outlines the constitution of the Royal School of Mines. Now finds he has to consult other professors before he can recommend Alexander [Herschel] for a Lectureship.
Has heard from Mrs. Greig [wife of Woronzow Greig] that JH has consented to read the proof sheets of Mrs. Mary Somerville's work on molecular science. Sends the first 44 pages and would be pleased for any comments. Mrs. Somerville is in Naples.
