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 letter from J. H. Lefroy in Athabasca [Canada]. Extract of C. J. B. Riddell's winter magnetic operations and summer plans along Red River.
Has been unable to reply to JH's note as he was ill. There will be a special General meeting of the society in November to hear the memoir of Francis Baily. Will send all the information as soon as possible. Has invented a new algebraic symbol.
A note accompanying a draft of the report on magnetic observations to date at British stations, and a circular to be sent out.
Hopes JH will write a memoir of Francis Baily.
Has sent a pamphlet on Education to the R.S.L. to be transmitted to JH. Explains the mechanism of his new anemometer. Is most interested in the causes of falling stars and their relation to meteorites. Has he seen [Robert?] Hunt's book on Light? Does he know where a description of William Parsons' (3rd Earl of Rosse) large telescope is to be found?
Glad to hear that there is a possibility that JH will visit York. Another expected visitor will be T. Donkin, brother of Bryan Donkin.
Begs JH to read enclosed [Essay on the Standard and Measure of Value, 2nd ed. 1832] by John Taylor and reconsider assisting the working classes.
Magnetic phenomena move in opposite directions in the northern and southern hemispheres. This contradicts a report made by JH. Asks permission to omit JH's statements concerning this issue.
Discusses publication of James Grahame's [History of the United States of North America] revised. Includes circular describing Grahame, his project and the cost of the books.
Advises that JH has been elected President of the B.A.A.S. for its meeting at Cambridge in 1845; also some comments on the magnetic survey.
