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.
Comparisons of the functioning of JH's barometer and that of TM.
Discusses JH's recent observations of Gamma Virginis.
Matters relating to providing observatory instruments to an expedition into Central Africa.
Informs TM that JH's 20-ft. telescope is fully in operation; invites TM to come and observe with it.
JH will break his rule about never going out when it is possible to sweep the sky, and dine with TM; will offer some help over mural circle problems.
Comments on social matters, and on what JH has been observing.
Oppressive heat prevents JH from visiting. Sending a list of furniture from Major John Ross's house, which JH definitely will purchase.
Saw a 'small round perfectly defined body' last night that looks like a planet.
Found a 'very fine' planetary nebula. Unable to learn anything conclusive from TM's microscope readings. JH's observation tower is erected and is currently being plastered.
Happy that TM is handling his facial paralysis so well; JH believes that it is due primarily to anxiety and overwork.
Gives location of a planetary nebula.
Predicting poor weather, JH advises TM not to go to the Grove tomorrow.
Invites TM to a meeting of the Meteorological Committee, which James Adamson, Abraham Cloete, and James Bance hope to attend.
Wants to learn more about JH's book-keeping system.
Thanks JH for reading Andrew Smith's letter.
