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.

Comments on a proposed grant to publish T. R. Robinson's Armagh observations.
Writing article [for Encyclopaedia Britannica] on meteorology. Asks questions regarding work of [H. W.] Dove and [Thomas?] Taylor regarding cyclone and storm theory. Discusses barometric fluctuation.
Thanks ES for his paper. Sun spot activity should increase in 1857. Discusses his own earlier ideas concerning relationship between sun spots and Aurora Borealis.
Discusses advantages of different magnetic charts. Grateful for [P.] Plantamour's observations. Satisfied with [J. R.] Wolf's period of 11.11 years for solar spots.
Heard ES recommended JH write an article for Edinburgh Review on terrestrial magnetism. Asks what he should read to write this article. Photographs ES sent of sun not promising.
Willing to write article if Quarterly [Review] will publish it, if he may take his time writing, and if ES will provide aid regarding meteorology and magnetism.
Thanks ES for receipt of information about magnetic curves and the work of [A. D.] Bache. JH is glad to hear ES is back to active work again, but JH says he is too ill to go to the B.A.A.S. meeting [in Aberdeen].
[Extract] Learned that JH was appointed by R.S.L. to committee to cooperate with B.A.A.S. to promote continuance of terrestrial magnetism survey. Asks ES to send committee summary of results already obtained and ES's opinion of how best to conduct future observations.
JH's improved health would allow him, if asked, to chair the Chemical Section at the B.A.A.S meeting. Notes that JH, G. B. Airy, William Whewell, and George Peacock have been appointed to a committee to cooperate with the B.A.A.S. committee dealing with the continuation of terrestrial magnetism observations.
Is glad to sign certificate. Complains about tendency of Alexander von Humboldt, whose volume Mrs. Sabine is translating, to ignore other scientists' work.
Must hold to 1/290 as measure of ellipticity. Committee agrees to recommend continuance of magnetic observations if JH will continue to do what he has done in the past.
Describes in detail proceedings of a committee meeting, particularly noting remarks made about ES and stressing committee's wish to see evidence of progress.
Sends G. B. Airy's remarks concerning ES's last communication. Discusses future of observatories. Asks ES to indicate which observatories he feels are most important.
Invites ES and his wife [at St. Leonard's] to visit . JH is impressed with ES's ability to develop a working plan for terrestrial magnetism observations. Is prepared to write a review article [about magnetism?] if invited, but JH refuses to write such articles and offer them 'for acceptance or rejection.'
Has incorporated ES's suggestions into the draft report about [the University of] Kasan.
Regarding report on magnetic observatories to be laid before R.S.L. president and council.
Discusses desirability of middle latitude stations in North America. Impressed by the work of [A. D.] Bache.
JH cannot attend Aberdeen [B.A.A.S.] meeting due to severe illness. Will try to sketch draft of response to application to British and foreign governments for cooperation in magnetic projects.
Requests information concerning a letter to the Treasury, which ES had asked JH to write, regarding funding for [meteorological] stations in Vancouver, Shanghai, Newfoundland, and the Falkland Islands.
