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.

Thanks for sending his Physical Geography. Wonders whether a rainbow could be reflected to the eye from water. Startled to read J. R. Hind's letter about the comet.

Comments on whether a rainbow could be reflected to the eye from water. Comets approach quite near to the earth on many occasions. Regarding the development of South America.
Is grateful for JH's views on the rainbow question. Intends to send his comments to the London Review, if he has no objections. What effects would the Comet have if it hits the Earth? Mr. Wheelwright appears to be in error on his earthquake views.
Has checked over JH's letter on rainbows and will have it signed Herschel. Encloses a scrap about rain. Mr. Wheelwright's note is curious. Will send a copy of the London Review.
