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.
Has requested Admiralty funding for the proposed telescope [see GA's 1845-11-2]; GA does not like the mounting the telescope is to be given; has gathered, from Otto Struve, that it does not work well at Pulkowa Observatory.
Is returning JH's report on William Simms's object glass [see GA's 1845-10-14]; GA reiterates Otto Struve's statement about the mounting at Pulkowa Observatory [see GA's 1845-12-1].
Passing on information received from a O. M. Mitchel[l] of Cincinnati regarding Antares, and the surface of the sun.
A note enclosing a copy of a letter from the Admiralty, on which JH is requested to comment.
Is skeptical of the American observations [see GA's 1845-12-8], and reports other observations communicated to JH.
Regarding estimates and payment for a parallectical mounting.
The Admiralty has approved the purchase of the telescope for the Cape Observatory [see GA's 1845-12-1].
A note of instructions about paying for the Cape telescope [see GA's 1845-12-20].
Regarding the condition for determining the best possible orbit for a double star.
Will consider GA's objections [see GA's 1845-12-27] when JH works further on double star orbits.
