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.
Asks the Physical Committee (Chair, JH) of the R.S.L. to note the concurrent disturbances of magnetometers and the appearance of aurora borealis, and to make a long term study of this relationship.
Points out an error in the instructions for magnetic observers provided for the Antarctic expedition.
Last letter to JH was private [see GA's 1845-4-1].
Gives detailed, official, replies to the questions in the magnetic committee circular [see JH's 1844-12-5].
Illegible.
Cannot explain why GA's letter did not reach JH.
Magnetic questions have been sent to foreign observers but not the British. Why?
Is not clear what the statement from Robert Peel means [see JH's 1845-9-29 or earlier].
Explains how the money from the Admiralty came to be awarded as it was [see JH's 1848-9-24].
Seeks opinions on discontinuing use of 25-foot zenith tube and altering form of printed observations for transit instrument and mural circle.
Sends GA's correspondence on the subject of the Admiralty grant, with further explanatory comments [see JH's 1848-10-28].
A note to accompany further copies of correspondence to the Admiralty [see GA's 1848-10-30].
Informs JH that GA (and his assistants) have been making pendulum observations in a coal pit.
Expresses some concerns about GA's having indicated support for a particular candidate for the Board of Visitors. [Very faint.]
Acknowledges receipt of JH's 1850-5-28; GA will pass on the news to some others.
Asks JH for comments on GA's proposals for the Standards Commission [see JH's 1840-7-29]; GA comments on some time spent recently in Glasgow and surrounding regions.
Considers paper by [Baden] Powell to be worthless. Sent it to JH today care of Mrs. Stewart.
Asks JH's opinion about GA's plan not to print a separate volume of magnetic and meteorological observations for 1848.
Will reconsider the proposal about printing observations [see JH's 1849-3-29], and get back to JH.
Is sending on G. G. Stokes instructions about polarization; several expeditions have left for more southerly locations to observe the upcoming solar eclipse.
