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.
Asking for introductions to certain men of science in Paris. Revision of his views on his figure of the earth, and casting doubt on Edward Sabine's pendulum observations.
Sending his paper on the 'Figure of the Earth.' Description of work at Greenwich Observatory. Remarks on projected expedition to Falmouth and Ashbourne.
Instructions regarding the printing of his paper the 'Figure of the Earth' in the transactions. Details of the disappointing expedition to Falmouth.
Thanking him for his letters of introduction to Paris. Remarks on one of GA's papers; one of his calculations incorrect.
Information on a Mr. Atkinson. Remarks on dispersion of rays in glass.
Further regarding parcels of books sent to G. S. G. Santini of Padova. Details and comments on telescopes used for observations.
