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.

His eldest son, Henry Seymour King, will deliver the annual oration at Charterhouse on 12 Dec. Would give him great pleasure if JH could be present.
Obliged for JH's kind and complete reply to his query on zodiacal light. Hopes the diagram will be included in the next edition of JH's book. Would like to include JH's visiting card in his album.
Is sending on G. G. Stokes instructions about polarization; several expeditions have left for more southerly locations to observe the upcoming solar eclipse.
Discusses his thoughts on high powered definition and residual aberration in microscopes. Thinks they may be applicable to telescopes.
Thanks JH for writing. Complains of obstacles to his work. Happy to see JH recognizes work begun by Blaise Pascal and continued by famed mathematicians. Asks JH to respond to AQ's wish to dedicate his book [L'Anthropométric] to JH with only one word: 'J'accepte.'
Is working on humans and their proportions. Encloses brochures. Wishes to dedicate L'Anthropométric to JH.
Thanks for suggestion-filled letter. Remarks on blue color of water.
Is sending G. G. Stokes's instructions about polarization. Observation parties are off to Oran, Gibraltar and Cadiz.
Is sending two copies of his book on magnetism [Treatise on Magnetism (London, 1870)].
Sending his apologies for some errors he made in his calculations in his letter of 30 Nov.
Has made a trial of JH's lens but it was too large to be satisfactory. Regarding the 'graphoscope,' a new toy. Has been concerned with the manufacture of an improved form of opera glass. Present forms have many imperfections. Gives details of his own theories and sends one for JH's notice.
Thanks for his letter. Is glad the binoculars give a satisfactory performance, but regrets the width between the tubes does not suit JH's eyes. Will alter this and send a new pair later.
Moon not uniformly dark during last eclipse of sun. In 1858, Mr. Stuart saw same phenomenon, but JH, W. R. Dawes, and [James] Breen reported no such partial illumination. Suggests that this observation was due to refrangibility in medium, not to actual illumination of moon.
Sends an article from the Astronomische Nachrichten acknowledging the assistance of the B.A.A.S. to two Prussian scientists.
