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.

Is glad he likes the idea of projecting more than a hemisphere. Compares his own projection and a stereoscopic projection and comments on the results. Is now having another projection made that should give an accurate map of America.
Is grateful for his valuable remarks on the various projections of the sphere. Thinks the projection devised by JH to be well suited for isothermal lines. Has constructed a chart of the polar regions for the same purpose. Will try JH's projection.

At the last meeting of the B.A.A.S. a resolution was adopted calling for the continuance of the Magnetical Observations. Would work through the joint R.S.L. and R.A.S. committees as before. Would JH agree to continue as chairman? Let him know at the Athenaeum where he returns in a few days.
