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.
Hopes JE will write to JH at Cape. Responds to JE's comments on JH's method of dealing with double stars. Thanks for generous comments on JH's Prelim. Discourse.
Tried unsuccessfully to observe Encke's Comet; succeeded in observing Halley's Comet, which JH discusses. Mentions JH's graphical method of treating orbits of double stars, JH's plans to return to England, moon maps, and sunspots.
Asks JE to express JH's gratitude to the Royal Academy of Berlin for electing JH a foreign member. Discusses JE's observations of divisions in the ring of Saturn, JH's sightings of Saturn's satellites, the British Antarctic expedition, and comets.
Asks if JE or the Academy of Sciences wish to participate in the British plan to make worldwide magnetic observations.
Thanks for his letter, which had been forwarded to his old address. Is pleased he intends working on double stars, though 70 Ophiuchi may prove difficult. Will send some of his own readings for double stars. Like him, he is astonished at the acrimony of the attack on Thomas Young and the Nautical Almanac.
