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.
Compliments WS on a written address. Describes how to set up a telescope to avoid unnecessary vibration; includes diagram.
Discusses the naming of a Plateau of Brussels. Discusses names to go on list; gives JH's and Michael Faraday's recommendations.
Thanks WS for 'kind expressions on my behalf.' Believes these may be the last words he may write.
Success of C. P. Smyth's Teneriffe expedition pleases JH; anxious for declination of nebulae taken from high altitudes. Upset over G. J. Stoney's reproduction of JH's collimating telescope without giving him credit.
Agrees to support C. P. Smyth for membership in R.S.L. Objects to C. P. Smyth's statement regarding his discoveries observing at high altitudes. Stresses importance of variable star work.
Has heard WS is publishing an English translation of François Arago's astronomical writings. Urges against including Arago's lectures if the Italian translation is indicative of their level of accuracy. Lists numerous errors in that edition. [Marked 'not sent.' Note added to CDraft (RS:HS 25.13.13) states: 'A letter differently worded but noting some of these points, but not all (for particular reasons) if I remember right was sent.'
Pleased that WS included François Arago's lectures in his compilation. Believes the Italian edition could have been better edited. Remarks on the Leviathan problem.
Makes suggestion on freeing the Leviathan from its trapped position.
Wishes to put WS's final version of Gamma Virginis orbit in new edition of his catalogue. Asks questions about Mediterranean.
Sends apologies to William Lassell for omission of discovery credit.
