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.
'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.
Asks JH's opinion of placement of some of William Herschel's documents. Agrees with JH on Neptune case, although he claims to have difficulty formulating an argument.
N. R. Pogson appointed to Madras Observatory. Appointment includes a pension, so a civil pension will not be necessary.
Questions dates in William Herschel's observations. Wishes JH luck on completing translation of Iliad.
Suggests Moyes Publishing Company to JH. Observes Encke's Comet. Visited by W. R. Hamilton and John Russell.
John Lee has obtained transit circle for Astronomical Society. WS suggests someone other than Thomas Maclear operate it so Maclear has time for occultation project. Details observations of aurora.
Sights bright patch on moon; asks JH to confirm the observation.
Unable to spot Biela's Comet. Outstanding observing conditions allow WS to sight normally difficult objects. Makes suggestions concerning JH's rotating roof plans.
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 observations of the double stars, which JH had suggested.
Reports conflicting observations of Gamma Virginis. Uses JH's method of measuring double star positions.
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.
Finds mistake in JH publication [Outlines Astr.] that assigned discovery of Hyperion to W. R. Dawes and G. P. Bond without crediting William Lassell.
Studies sidereal chromatics. Asks if William Herschel recorded colors of Beta Cygni in a 1779 observation.
Very impressed after meeting W. R. Dawes and discussing double stars with him. Asks JH to send Gamma Virginis observations from Cape.
Awaits copy of JH's Telescope. Problems with by-laws of R.A.S.
