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.

Apologizes for delay in writing. Describes JH's travels across Europe back to England. Is sending GP copies of JH's papers in physics, mathematics, and astronomy, especially double stars. Describes a new instrument, a floating collimator, described by Henry Kater at the R.S.L. [Rough notes for a later letter on the back of part of this one.]
Is helping another scientist bring to publication a work on triangulation in the Alps. Comments on JH's idea of suspending an extremely long plumb bob at a particular precipice in the Alps [Foucault pendulum?]. GP does not believe the results would warrant the expense. Comments on the floating collimator [see JH's 1825-1-14], noting that he does not find it very helpful.
Is preparing a paper on planetary perturbations, which GP would like to send to the Astronomical Society for publication. Comments on JH's ideas on the subject of perturbations. Would the paper being in French be a problem? Comments on Henry Kater's method for finding the zero point in his meridian circle.
Pleased that Astronomical Society will publish GP's memoir (in French) [see GP's 1825-5-27]. Adds some comments for clarification on points in paper and makes arrangements for copies of the paper.
Inquires about the arrival of the memoir sent by GP to JH [see GP's 1825-7-28].
Is very concerned because JH's recent letter did not comment on the arrival of GP's memoir [see GP's 1825-10-24]. Comments on printing and arrangements for copies.
Is pleased that GP's memoir has finally arrived in London [see GP's 1825-11-19]. Indicates arrangements for paying for copies. Comments on GP's astronomical observations of the last several years, and on his method of making reductions.
