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.
Excellent weather for observations of variable colors [in stars].
Sends JH copy of his address to Royal Geographical Society. Inquires about a means to make astronomical instruments steadier with poles devised by JH.
Writes that he was not aware of W. R. Dawes's hand in discovery of Hyperion; will note this in R.S.L. records.
JH's letter of recommendation for C. P. Smyth misdirected. Little time remains for nomination.
Thanks JH for advice on several persons and for suggestion concerning the Leviathan. Remarks on R. C. Carrington's circumpolar star work. Writes to R.S.L. Council concerning François Arago's nomination for medal.
'Making perhaps my last attack' on Gamma Virginis. Night air is increasingly detrimental to health.
Visited Liverpool for inspection of School Frigate. Observed Triton. C. P. Smyth will install large telescope at Alta Vista; WS sends excerpt from son's letter. C. P. Smyth also works on spectral line observations.
Finds mistake in JH publication [Outlines Astr.] that assigned discovery of Hyperion to W. R. Dawes and G. P. Bond without crediting William Lassell.
Sends JH copy of his work on Mediterranean; answers some of JH's questions.
Thanks JH for a copy of the new edition of Outlines Astr.
Asks JH to recommend C. P. Smyth for R.S.L. fellowship. Will avoid R.S.L. meetings due to declining health. Considers a second edition of Cycle of Celestial Objects.
Thanks JH for discovering an important error in a work WS asked him to proof read. Asks JH about a variable in Canis Minor over which there is some debate.
Elaborates on JH's questions concerning the Mediterranean. Refers him to Capt. [T. A. B.] Spratt.
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.
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.
Discusses the naming of a Plateau of Brussels. Discusses names to go on list; gives JH's and Michael Faraday's recommendations.
Compliments WS on a written address. Describes how to set up a telescope to avoid unnecessary vibration; includes diagram.
Sends apologies to William Lassell for omission of discovery credit.
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.'
Wishes to put WS's final version of Gamma Virginis orbit in new edition of his catalogue. Asks questions about Mediterranean.
