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.
JH's article on 'Meteorology' [for the Admiralty Manual] is finished; JH will make some comments on aneroid barometers in the preface.
M. McCann sent his paper to JH for communication to the R.S.L., which he did, but does not know the outcome of it. Was unable to report on it as his own knowledge was not modern enough.
JH replies to RS's 1849-1-15.
Says he will guardedly write in his Outlines Astr. what he has to say about Neptune and the controversy surrounding its discovery. States that he eschews formulae.
Further to reception of results from FA [see JH's 1848-12-23].
Arrangements about how the R.A.S. meeting will proceed.
Asks WW, as one of the trustees of JH's marriage settlement, to sign some legal documents.
Returns H. P. Brougham's (Baron Brougham and Vaux) paper. Does not recall any similar theories, but does not think his own theories are shaken by those of Brougham. Finds that AD has already done extensive work on the calendar.
Received news today of JS's arrival in Bombay. Describes conflict as 'Armageddon.' Family news. John Stewart returned from China and leaves soon to meet Matilda [Grahame] in Paris. [Richard] Jones's concern for JS is genuine. Eneas Mackintosh obtained cadetship for JH's son John at Addiscombe.
On return of a paper, and approval of AD's method of resolving fractions.
Tells GA about the internal counterpoise system in use in some German telescope mountings, and includes a diagram; JH knows nothing about chilling speculum metal [see GA's 1849-3-7].
About an astronomer for the Madras observatory. Suggests ways to reduce glare and so improve measurements [see RS's 1849-3-4].
Arrangements about JH coming to London to go with SC to see John Russell (1st Earl Russell) [see SC's 1849-3-17].
Has just been able to consult Sir William Herschel's papers. Regarding Yvon Villarceau's method of measuring the orbits. May be like his own, which he briefly outlines.
Sends AD part of JH's paper on double stars; concerned about AD's dating it on arrival.
Found his letter on return from London. Would be pleased for UL to submit part of his letter of 19 Mar. to the Institute. Further comments on part of this letter.
Another part of JH's double star paper; question of priority between JH and Yvon Villarceau.
Correction to JH's paper on double stars [see JH's 1849-3-26 & 1849-3-25].
Correction to paper on double stars following up JH's 1849-3-26; a terrible pun sent on by JH's wife, Margaret.
Some concerns about GA's intent of attaching magnetic and meteorological observations to the R.A.S.'s Astronomical Observations [see GA's 1849-3-28].
