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.
Amuses himself in his spare time with astronomy. Would like advice on the composition of the metal for the speculum. Hears that Miss Caroline Herschel is in good health.
Thanks for letter and advice. Has been able to get copies of William Parsons' (3rd Earl of Rosse) papers. Would like advice on the size of the grinding tool. Hopes to avail himself of JH's invitation to visit Collingwood.
Has now succeeded in grinding his 20" speculum and it is ready for polishing. Would like to see the mounting of JH's telescope as it is not clear from the engraving.
Is grateful for JH's offer of assistance and proposes to visit him next Wednesday. Congratulations on the addition to his family.
Has been unable to return the papers as he has been so busy. Proposes making working drawings as he suggests. Will take the papers to the Dover Railway to ensure their safety.
Encloses the tickets for the Philharmonic concerts and gives details of the program. Is going to cast another 20" speculum in a few days.
Did not realize that JH would leave town so quickly. Cast a 10" speculum successfully after William Parsons' (3rd Earl of Rosse) plan. Is having difficulty with his grinding and polishing and would welcome JH's advice.
