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.
Encourages GA to consider favorably the offer of Hugh Percy [Duke of Northumberland] of donating a telescope to Cambridge Observatory.
Does not believe that GA's proposal [see GA's 1848-5-4] will work.
Details about proposals for magnetic expeditions, as they are to be presented to British government [see GA's 1838-11-12]. Also included is a copy of the resolutions passed at a B.A.A.S. meeting on 25 Aug. 1828.
Comments on a proposed request for a government grant to establish a magnetic and meteorological institute.
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.
Nine conditions under which JH will accept and test instruments constructed for Cape [of Good Hope] observatory, including the assistance of Mr. Davies in evaluating these.
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].
Recommends buying optics for 7.5-inch telescope from Metz and Mahlers in Munich and having those mounted in London.
Gives detailed, official, replies to the questions in the magnetic committee circular [see JH's 1844-12-5].
Illegible.
A note to accompany some letters being returned to GA.
Has received a request from the Admiralty to order a new telescope for the Cape observatory; at the same time, JH has received an unsolicited offer of a lens. JH seeks advice and information from GA.
Will try to organize an international magnetic conference at the B.A.A.S. meeting in 1845, if GA agrees.
Apologizes for having questioned GA's proposal [see GA's 1848-5-6], which is very good and should work well.
Cannot explain why GA's letter did not reach JH.
Changing a date of meeting for the magnetic committee of the B.A.A.S., and inviting GA to be there.
Believes he has discovered a second satellite of Neptune; gives readings.
Thanks GA for offer of accommodation [see GA's 1844-11-2], but JH says he must stay with Miss [Elizabeth] Baily at Tavistock Place.
Magnetic questions have been sent to foreign observers but not the British. Why?
