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.
About the establishment of a standard yard, and how the Kew Committee should proceed [see JH's 1851-11-5]; RS also plans to prepare standard thermometers. Received notice of William Lassell's discovery of more satellites of Uranus.
Tells JH of RS's dealings with the Kew Observatory Committee; comments further on standard thermometers.
Asks JH to sign certificate for membership in R.S.L. for William Simms.
Thanks JH for his attention to his request. Has inquired about the etiquette of members of the Council signing certificates: it is done, though not regularly.
Argues cogently against the policy of the Council [see JH's 1852-1-16]; is continuing his work on the standard yard.
Suggests that JH assist William Lassell's travels to Malta by asking for a letter of introduction from the Duke of Northumberland; is concerned about the precarious position of the observatory at Altona, and of the Astronomische Nachrichten published there.
Make a few suggestions about JH's letter to Adolph Petersen [see JH's 1852-5-19].
