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.
Wants to visit the Royal Mint; the coinage/weight question is more complex than GA imagined [see GA's 1853-3-15]; seeks JH's opinion on part of a letter to the Chancellor of the Exchequer.
Details of how coins are tested and stamped for weight. Procedures are not regulated, and variances are common. Encloses Mr. Miller's letter on decimal coinage. [JH annotation: 'Substance sent to Airy March 21 / 53 but altogether diff in form and wording.']
Responds with return of letter part and an invitation to the Royal Mint [see GA's 1853-3-21]; expands further on the coinage/weight problem.
Regrets will be unable to be steward at a 'Public dinner.'
