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.
Invites JH to R.A.S. dinner on 9 Jan. to meet Sir G. C. Lewis.
Concerning Thomas Maclear.
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.
Is sending JH the completed sheets of nebula reductions for printing [see JH's 1863-2-6].
Once again anxious about completion of nebula catalogue, and about cost over run [see Edward Stone's 1863-1-14].
Sends a final accounting for the calculating work done at the Royal Observatory on JH's nebula catalogue [see JH's 1863-2-7].
Acknowledges receipt of nebula catalogue sheets from GA [see GA's 1863-2-6]; apologizes for JH's anxious letter [see JH's 1863-2-6].
Giving results (including diagram) of a comparison of earth currents and magnetometer disturbances.
Offers a few ideas to GA [see GA's 1863-2-9], but does not have a coherent explanation.
Has found a few minor errors in the calculations checked so far [see GA's 1863-2-6]; comments on magnetic tracings JH received from GA.
Will take into account JH's suggestions [see JH's 1863-2-13] and see where this leads.
Is JH interested in seeing G. F. J. A. Auwers's catalogue of JH's and William Herschel's nebulae?
Did JH receive G. F. J. A. von Auwers's catalog of JH's and William Herschel's nebulae?
Might have saved JH some work if he had known what G. F. J. A. Auwers was doing [see GA's 1863-2-20]; has found some more errors in nebula calculations.
Sends copy of G. F. J. A. von Auwers's catalog of JH's and William Herschel's nebulae. Observatory has another copy. Notes odd lines seen in 'Refraction Spectra of 11 stars.'
Refraction spectra of six stars exhibit lines corresponding with 'Solar Line F.'
Expect some errors in calculations of positions for JH's catalogue of nebulae. Suggestions on format.
Does JH need the original calculation sheets to deal with the errors in the nebula catalogue [see GA's 1863-2-23]?
Explains how to detect errors in catalogued positions of stars. List of new nebulae in [G. F. J. A.] Auwers's catalogue.
Sends GA a list of errors found in the sheets for the nebula catalogue [see GA 1863-5-14].
