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.
Is working on a compilation of the measures of double stars. If [Rudolf] Wolf's period of 11.11 years is correct, why should 1810-11, a minimum, mark the first observations of solar spots?
Sends [William Whewell's] 'Isle of Sirens' and an acknowledgement to it in 'skimble skamble Hexameters.' Is eager to receive solar photographs and will send others by Professor [George?] Morton.
Discusses discrepencies between his observations for September and WS's photograph. It seems the new spots result from Jupiter being in opposition.
Describes the similarities between JH's sketches and WS's photographs of sunspots. Has greater faith in own observations. Wishes WS would add Julian dates. Sends Professor [George?] Morton's photographs.
Has been translating into Latin 'your Dean's "Kentish Fire."' Has good Latin versions of [Oliver Goldsmith's] 'Edwin and Angelina' by Lord Stratford de Recliffe and of [Thomas] Gray's 'Elegy' by 'Chief Justice [Henry Thomas?] Cockburn.' Sends his 'Genevieve.'
Has autographs that display the activity of the sun. Sends sonnets he has written. Asks JH to mention distribution of nebulae at R.A.S.
