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.

Wishes to have mentioned to the Physical Section of the B.A.A.S. that JH has discovered that the extreme red rays [infra-red?] of the sun do not darken photographic paper, but tend to whiten it.
Asks JL to take on the preparations for the magnetic observations, including the instructing of ships' personnel.
About times at which magnetic observations should be made at each observation station.
Report to B.A.A.S. on progress and expenses in reduction of stars in N. L. Lacaille's Coelum australe stelliferum.

The 20-ft. reflecting telescope used at Cape Town was delivered safely to Slough.
F. E. Wilmot arrives in Cape Town for direction of the Magnetic Observatory.
Sympathizes with GA in the family sorrow [deaths of GA's sons Arthur and George]; JH complains that house hunting, and other matters, are keeping him from important work.
