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.

Excerpts from a letter to the R.S.L. that accompanied copies of GP's work on lunar theory.
In his travels, GP met James Stewart (Margaret Herschel's brother); gives GP's assessment of James Stewart. Comments on JH's intended voyage to the Cape, and wishes him well.
Comments on communications with the Cape. James Stewart (Margaret Herschel's brother) is well liked by the family. GP is sending on his meteorological observations, noting that he has reduced his emphasis on astronomy. Is working on a long memoir on integral calculus. [Many parts of the letter are illegible.]
Has made meteorological observations as desired by JH, and has sent and received various sets of such observations. Would like to come to England to visit JH, but first wants to find a husband for his only daughter. GP's assistant at the observatory died and he is looking for a replacement. [Many parts of the letter are illegible.]
Reports on sending and receiving barometric and magnetic observations. GP's 20 year old daughter is still not married [see GP's 1838-1-6], but GP believes her chances are improving.
