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.
Has received JL's memoir on the tides. JH would like to amalgamate certain portions with a memoir from William Whewell. JH adds some comments on photographic experiments he has made.
On the 'misfortunes & mishaps' of the Aden magnetic observatory and on the proper care of magnetical instruments.
Has read over all JH's report. Makes suggestions for alterations and omissions to bring it into line with the wishes of Council.
Sends a copy of his work on the tides. S. D. Poisson's theory is noticed near the end of the 2nd volume of Mécanique. Thinks some experiments are necessary to find the effect of the sun on climate. Has received a note from the Treasury.
Would like JH to amalgamate William Whewell's and JL's memoirs. Thought the principle of universal gravitation was conceded by all. Treasury have sent back the bills and want the Antarctic ones separated from the Observatories ones. Should take notice of the effect of iron steams [on instruments?].
