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.
Encloses note about transportation of rockets, telescope, and chronometer, with suggested schedule for experiments.
Reports on his meeting with Charles Bonne and their subsequent failure to see any signals the first night from either Mont Javoul or La Canche. Worries that the distances are too great for measurements so close to the sea. Speaks of similar measurements between Paris and Strasburg.
Reports his 'entire failure' with Charles Bonne to see signals from both La Canche and Mont Javoul on the same night. Tells of moving the telescopes to Tuniers on 1825-7-15. Speaks of similar experiments elsewhere, which also failed. Concludes that distance is not the only factor in distinguishing signals. Plans to visit JH on 1825-7-25.
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.
