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.
Reports Charles Bonne's voyage to Mont Javoul and discovery that the rockets there had been sent off too early, accounting for the previous failures. Reports subsequent successes. Conveys his plans to arrive at Teneriffe.
An account of the rocket experiments and P. S. Laplace's letter will be left at the R.S.L. Finds in Laplace's letter encouragement for the corroboration regarding the measurement of latitudinal degrees. Dismisses Laplace's opinions that the climate of Spitzbergen is too unfavorable for experimentation and expounds on the many reasons to favor this town.

Completing the catalogue of 2500 nebulae. Impressed with a French biography of William Herschel, although CH notes a few occasions where 'too great a stress is laid on the assistance of others.'
