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.
Suggests new method of gold plating the telescopic mirrors to prevent oxidation. Mentions having tried to galvanize the mirrors with 'Galvana plastik.'
Tells JH that his travels will take him to London. Requests time and day when they can meet personally in Kent.
Tells JH that his invitation to visit came too late. Regrets deeply not having the opportunity to meet, but expects to do so next year. Hopes to present two works to JH at that time. Mentions working with the talented P. L. Seidel, his assistant.
Tells JH of [P. L. von] Seidel's success in comparing luminosity of stars by means of a photometer. The results match those of JH. Sends JH a copy requesting that the form be ignored and it be communicated to the R.A.S.
Thanks for suggestion of gold plating the telescope mirrors. Mentions idea of mounting a reflector horizontally but finds its execution 'insufferable'. Thanks for work on photometric measurement of light of stars. Disagrees on some results. Encloses new photographic specimens.
