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.
Regarding the strange appearance of the comet of Biela. Will observe the double star as soon as he has an opportunity.
Is obliged for his notice of the separation of Biela's comet; has sent extracts to H. C. Schumacher. Sends some observations made that evening. [Francesco] de Vico announces a new comet; so far he has been unable to trace it.
Has not been able to secure any angles of Gamma Virginis due to poor weather. Perplexed over the difference between J. H. Mädler and W. R. Dawes. George Bishop will be pleased to send any measures he may require.
Sends his observations of y Cygni. Comments on the differences in the readings of various observers. Still unable to observe the double star JH requested, but the weather has been poor.
Obtained first rate measures of the double star on 31 May, but since then the atmosphere has been hazy and so unable to send any further measures. Thinks it worthwhile to observe all the stars in Cassiopeia and Ophiuchus.
Elements of the new comet observed at Regent's Park.
In case he has not received a letter from Berlin he sends details of the planet of U. J. J. Leverrier.
