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.

Has a few pounds surplus from the subscription for JH's vase and wonders if it could be used to supply a plinth for the pedestal. Does JH agree? Perhaps Lady Herschel can supply the wording.
Along with the Lord Advocate and other Scotch members of the House of Commons had an interview with [Thomas Spring-?] Rice concerning the enclosed memorial (Observatory of the University). Comments on their proposed plan for the work of the university.
Wants to withhold description of 'developing' process until it is perfected to obviate others using it. Also refers to second process to make 'positive' and 'negative.'
Some comments on JH's light and photography experiments, especially effects of different kinds of glass and fixing with ferrocyanate.
Describes mediocre results obtained using ferrocyanate of potash for fixing image. Mentions some other methods, including his favorite, common salt. Asks JH to keep these secret.
More about paper being published in both the R.S.P.T. and Athenaeum.
Finally had success washing with ferrocyanate. Wants to present note of 'his' processes to R.S.L. and so to the world.
Wishes to communicate to J. B. Biot, and so to Academie des sciences, JH's two 'beautiful' fixing methods, by hyposulfite and ferrocyanate.
Questions JH's intent to display 'photogenic drawings' to R.S.L.
Discusses own efforts in meteorology. Must wait to print second edition of work on storms. Appreciates nomination for R.S.L., but has little time for such pursuits.
Asks permission to use information from JH's letter in Astronomische Nachrichten. Believes [Alexander von] Humboldt can explain observational anomalies that JH notes.
Sends JH pamphlet on intimate connection between a country's zoology and its political statistics. Regrets that JH wished not to be nominated for presidency of R.S.L. on returning from Cape.
Asks JH to keep him updated on English research of the dynamics of light. Currently considering the 'propagation' of light waves, as distinguished from their mere 'preservation'; asks whether this is a new study.
Awaits decision on his fate as Lieutenant Governor at the Cape.
Further observations on the alterations at Cape Town Observatory. Any news of the measuring bars?
Thomas Maclear's assistant and equipment arranged. Observations on copper horse-shoe bars applied to the end of his magnet.
Inquires about appropriate person to add to the Cape Observatory staff, if FB can persuade the Admiralty of the need. Thanks JH for his comments on chloride of silver; were much better than W. H. F. Talbot's.
Unable to see him as he has another meeting to attend. Regarding the loan of the R.A.S.'s theodolite to Thomas Maclear. Two foreign members have been proposed for the R.A.S.
Will compare the standards later. Has sent the theodolite to the Admiralty and received a letter of thanks. Thomas Maclear's paper on N. L. Lacaille's star positions will be read at the next meeting of the R.A.S.
