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.
[A. C.] Petersen [?] claims to have found a new comet near JH's nebula #379. Look for it, but do not announce this discovery.
Asks JH to accept sunspot observations made over 14 years by the late [J. W.] Pastorff of Altona Observatory. Accompanying micrometrical measurements are worthless due to mounting of telescope.
Sends [J. W.] Pastorff's solar observations [see HS's 1850-4-16] as JH's own property.
Reports that [Annibal] de Gasparis has discovered a new asteroid, Parthenope. Gasparis credits JH with the discovery because JH had proposed the name Parthenope when AG had discovered Hygeia.
Alexander von Humboldt requests that JH answer questions about 'coal sacks (plur.)' [Coal Sack of the Southern heavens].
