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.
Received the enclosed communications by the steamer. Can JH send him a list of unobserved comet stars? Work on N. L. Lacaille's Observatory gives satisfaction. Regarding Capt. Mackonochee. Lacaille's angular measurements are not above suspicion. Observed the two rings of Saturn distinctly.
Will call on JH tomorrow as he intends visiting Simon's Bay. Is taking a proof sheet to Cape Town. There appears to be a great discrepancy between the Captain's statement and N. L. Lacaille's station. The latter's station at Rubeck Castel remains perfect.
The examination of the standard deal rod was commenced yesterday. Comments on the procedure and gives readings. The base line was levelled on Wednesday, Thursday, and Friday and he is now ready to measure it. Would like JH to be present if possible when he measures it. Had 25 visitors in one morning recently.
Returns JH's book of estimated magnitudes and would like it again when preparing his catalogue. Sends letters he received from Francis Beaufort and [Richard?] Jones. Is oppressed with business and an awful cough.
About the observation of sun spots and the second satellite of Saturn.
Asks TM to return JH's book of star magnitudes.
