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.
Raises with GA the likelihood of an error in a date of a transit of Mercury in a paper by F. A. Winnecke.
Offers some possible explanation for what the unnamed observer saw [see GA's 1860-3-1].
Is preparing a list of nebulae and their positions; does GA think anyone would print them?
Suggests preparing an estimate of the cost of preparing and printing a nebula catalogue so JH can approach the R.S.L. [see GA's 1862-1-24].
Ready to send nebula data to GA for reduction; question of dates need decisions [see GA's 1862-1-30].
Is sending first part of observational data for nebula catalogue [see GA's 1862-3-31].
Forgot, in earlier note [see JH's 1862-4-2], to indicate agreement with GA's suggestions [see GA's 1862-3-31].
Responds carefully to the question of observational, and reduction, dates [see GA's 1862-4-12].
Has now sent the last of the nebula observations to be reduced for printing [see GA's 1862-4-16].
Approves of form for reduced observations [see GA's 1862-4-24] and sends GA payment against expenses.
Provides final intended structure of the nebula catalogue page [see GA's 1862-4-26].
Provides the information in response to GA's request for the position of one nebula [see GA's 1862-5-27].
The R.S.L. grant is almost used up; how much more money will be needed for the nebula catalogue [see GA's 1862-6-25]?
In view of the additional costs, should the nebula catalogue be reduced to a 'working list', or should JH go back to the R.S.L. for more money [see GA's 1862-6-29]?
Seeks state of the nebula catalogue so an accurate estimate of the remaining costs may be made [see GA's 1862-8-1].
Expects R.S.L. to provide additional money, but JH will finish work himself rather than go over the amount granted [see GA's 1862-8-12].
Is working on the descriptions of the nebulae for the catalogue [see GA's 1862-9-2].
Asks GA for a copy of G. F. J. A. Auwers's nebula catalogue [see GA's 1862-11-17], and a sample of the nebula listing for JH's catalogue.
Anxious to receive final sheets of nebula catalogue from GA [see GA's 1862-11-19], as JH wants to enter the descriptions and complete the work.
Once again anxious about completion of nebula catalogue, and about cost over run [see Edward Stone's 1863-1-14].
