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.
Sends Gamma Virginis data. Will report Aurora Borealis observations to R.A.S.
Disappointed with format of Nautical Almanac. Arguments over this have caused many hard feeling among R.S.L. members. Details the controversy.
Thanks JH for recommendation of C. P. Smyth. James South returns from Ireland; reports great observing conditions there.
Lunar model will be placed in Somerset House.
Sends correction to data for Gamma Virginis. Asks if JH has 'considered the puzzle of Aristarchus [lunar crater]' discussed in WS's Cycle of Celestial Objects.
Double star orbits not ready; R.A.S. waiting for JH's new calculating method. Reads accounts of Biela's Comet. Describes Edinburgh Observatory in detail.
Studies two possible orbits of Gamma Virginis; sends complete descriptions of both, including calculation of the apparent and actual ellipse. The first orbit combines the data of other astronomers.
R.A.S. making exception in letting J. H. Mädler's chart be removed for JH. Continues observation of Gamma Virginis.
Discusses importance of Gamma Virginis: 'I consider it a grand key to several important physical points.' W. R. Dawes claims to have observed a third Uranian satellite.
Pleased with JH Gamma Virginis observations. 'Lunar affair' disappoints WS. Cycle of Celestial Objects being translated into Italian.
Discusses controversy over the discovery of Neptune. Astronomical committee of R.S.L. advised to award U. J. J. Leverrier the Copley Medal.
W. R. Dawes observes sub-division of Saturn's rings. WS continues observing double stars recommended by JH.
Asks JH for description of JH's 'little sweeper' telescope; plans to give a sketch of it in WS's book.
Receives report on poor state of Paramatta Observatory. Encloses letter from Thomas Brisbane, who believes James Dunlop should be removed from his post of authority there.
Sends copy of J. R. Hind's observations of Gamma Virginis; believes they are 'too slow.' Also sends report of the Charter Committee of the R.S.L. Believes R.S.L. not selective enough. Has difficultly using JH's method of magnitude determination.
Discusses magnitude determination. Refers to incident in which one of WS's sons will be removed from his position but not given poor references. W. S. Jacob sends double star measurements.
Gratitude for [Cape Results]. Feels JH 'let off [James] Dunlop in a softer stile than he deserves.'
