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 got his paper on shooting stars. Comments on JL's theories of meteors. Pleased to hear a favorable account of Montague Lubbock.

About the barometric formula for the measurement of heights.
Has received the books. Began with Karl Holtzmann's and finds the reasoning at fault. Comments on this. [Marked 'not sent.']
Asks JL to take on the preparations for the magnetic observations, including the instructing of ships' personnel.
R.S.L. business about an observatory at the North Cape in Sweden.

Arrangements for JL's presentation to be made to the R.A.S.
Is sending a letter of support for a neighbor for the position of commander of constabulary about to be established in Kent.
Has received JL's memoir on the tides. JH would like to amalgamate certain portions with a memoir from William Whewell. JH adds some comments on photographic experiments he has made.

Believes that R.S.L.'s request for £3000 grant to establish permanent magnetic and meteorological observatory is too hasty. Urges caution. Points out potential problems.
Explains JH's objections to JL's shadow-extinction hypothesis of meteors. Believes that several sorts of meteors—magnetoelectric, stony, vaporous, etc.—exist.
Is unable to come to London for the Standards Commission meeting and thus will also not be able to come to the dinner party. Encloses some recent photographs.
JH comments on JL's 'memoir on the heat of vapours,' indicating JH's dissatisfaction with the experimental basis (the experimental work of J. L. Gay-Lussac) for the conclusions. JH offers improvements in the construction and operation of the ice calorimeter.
