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.
Wishes CH a happy 96th birthday. Reports that when Margaret Herschel's brother John Stewart was in Egypt, he saw a comet. JH remarks that 'there seems to be no end of the comets.'
JH expresses pleasure in receiving and reading extracts from CH's biography. Expects to begin printing his Cape Results by Christmas. In finalizing his Cape Results, JH has found that several Southern double stars moved in the five-year span of his observations.
George Airy, George Peacock, and [Adam] Sedgwick are visiting Collingwood for Christmas. Airy writes JH that an American astronomer named [Ormsby] 'Mitchell' has seen Antares double. JH reports that William Lassell and W. R. Dawes have observed the 7th Saturnian satellite and also another of the six satellites of the 'Georgium Sidus' [Uranus]. JH is confident that his Cape Results will go to the presses in January.
