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 evaporation of water as a source of electricity. Magnetic results in relation to the North Atlantic.
Encloses printed copies of letters received from Johann Lamont regarding apparatus for examining Galvanic currents in the earth; would like his comments on them. Gave lecture in Manchester on the eclipse.
Encourages GA to develop some experiments to study the electrical phenomenon [see GA's 1861-9-23] more carefully.
Not surprised that actual costs [of publishing JH's catalogue of nebulae] departed from estimates. Reports vote by [R.S.L.] committee. Does not believe publication will be expensive.
Has sent an R.S.L. membership application certificate for GA to sign and send on.
Is preparing a list of nebulae and their positions; does GA think anyone would print them?
[Responding to JH's 1862-1-23], states that R.A.S. finances not sufficient to publish JH's 'Catalogue of Nebulae,' but R.S.L. is 'rolling in wealth.' Work could be done at [Greenwich Observatory], where GA is already printing 'Skeleton Forms for Precessions.' Forwarded R.S.L. certificate for [E. J.] Lowe to W. H. Smyth.
Suggests preparing an estimate of the cost of preparing and printing a nebula catalogue so JH can approach the R.S.L. [see GA's 1862-1-24].
Estimates seven weeks and £10 to compute JH's nebulae data. Suggests JH use new 'Skeleton Form.'
Returned JH's 'original sheets of nebulae.' Kept sheets of calculations. Will write about money accounts later. Lord Palmerston's communication about Thomas Maclear's pension.
Ready to send nebula data to GA for reduction; question of dates need decisions [see GA's 1862-1-30].
Send quickly JH's manuscript of 'Catalogue of Nebulae.' It will provide work for computer whom GA was about to lay off. Prefers reducing JH's data to 1860's. GA's improvement on F. W. Bessel's reduction formula.
Is sending first part of observational data for nebula catalogue [see GA's 1862-3-31].
Forgot, in earlier note [see JH's 1862-4-2], to indicate agreement with GA's suggestions [see GA's 1862-3-31].
Material sent by JH [see JH's 1862-4-2] arrived safely.
Acknowledgment of receipt of more material from JH [see GA's 1862-4-3].
Needs to know, from JH, the date of the nebula observations [see GA's 1862-4-9].
Responds carefully to the question of observational, and reduction, dates [see GA's 1862-4-12].
Acknowledges receipt of more material from JH [see JH's 1862-4-13].
Has received notice from the Foreign Office that the Russian Government has sanctioned the establishment of a magnetic and meteorological observatory at Pekin.
