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.
Concerning the method of observation by direct and reflected vision.
Will forward Cape Results to F. B. G. Nicolai at Mannheim Observatory.
Thanks GB for making exception. Will send copies [of JH's Cape Results] immediately to American legation. Offers personal copy to GB. Notes national and private efforts at astronomy in America.
About observing stars with the transit circle, and timing the annulus [of an eclipse?].
Was too cloudy to observe the eclipse; very worried about the health of Thomas Maclear.
Gratitude for receipt of JH's Cape Results.
American ambassador George Bancroft gave permission for envoy to transmit official copies [of JH's Cape Results; see SE's 1847-9-23 and 9-28]. Smith, Elder & Co. retrieved all letters written to American recipients before these were sent from American consulate. Gratified to receive JH's permission to publish [JH's Cape Results]. Already have several orders. Encloses Bancroft's letter.
