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.
Prof. Barlow's paper on 'fluid refractor' leaves WS doubting JH's report of Beta Capricorni.
Thanks JH for Gamma Virginis observations, which are finally in accord with his. Sends observation of the double stars JH suggested watching. Works with Richard Sheepshanks. Francis Baily delivers details on Edinburgh meeting of philosophers. Sends news from Niccolo Cacciatore, who has returned to the Observatory in Naples.
JH letter on Gamma Virginis read at R.A.S. meeting. Niccolo Cacciatore appointed to new position at Palermo Observatory, where he plans to sell the Almanack. Many R.A.S. members experimenting with telescopic lenses.
Wants to know if JH has a larger telescope in operation; if so, will he confirm some observations. Asks JH to recommend an epoch.
Will observe transit [of Mercury] hoping it will provide good meridian data. Encloses sketch of telescope in Bedford.
Thanks JH for kindness to C. P. Smyth. Francis Baily re-elected president of R.A.S. W. S. Stratford prints a comet ephemeris.
Will be able to receive JH during Cambridge trip.
Sends best wishes for JH's journey to Cape. Regrets missing him at Bedford during Cambridge trip.
Meets Lord Bute at Oxford. Requests JH observe Gamma Virginis, Castor, and Polaris with WS's 10-ft. achromatic telescope.
Suggests Moyes Publishing Company to JH. Observes Encke's Comet. Visited by W. R. Hamilton and John Russell.
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.
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.
Very impressed after meeting W. R. Dawes and discussing double stars with him. Asks JH to send Gamma Virginis observations from Cape.
Pleased that JH has received knighthood. Observes Alpha1 Capricorni in attempts to see a double star. Thanks JH for double star observation outlines; asks for a 'large supply' of them.
Sends micrometer observations of stars suggested by JH.
Adds clock to telescope, enhancing distance measuring power. Search for Halley's Comet begins. Reports double star data; observes nebulae in JH's Catalogue of Nebulae. R.A.S. location moved to Somerset House. Quarrel between James South and Richard Sheepshanks being arbitrated.
Describes factors that led to C. P. Smyth's appointment to Cape. Uses rock crystal prism for double star observations. Continues observing JH's nebulae with equatorial clock. Approves of proposal for worldwide meteorological observations; will distribute brochures.
Has difficulty observing sun spots. Thomas Maclear sends WS information for next year's occultation of Alpha Tauri. Completes rotating roof for personal observatory.
