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.
A letter accompanying a 'fair copy' of the Report of the Standards Commission; GA indicates he has incorporated the views of all members of the Commission.
Another copy of the Report of the Standards Commission is being circulated [see GA's 1841-12-25] and needs JH's signature; J. E. Drinkwater is sending in a personal report complaining about the Commission's conservatism.
Sends JH the current position of Gamma Virginis.
A new committee on standards is to be created to oversee the preparation and measuring of appropriate standard measures; seeks JH's opinion about asking Francis Baily and W. H. Miller to do the accurate weighing and measuring.
A notice of meeting of the Standards Committee.
Provides JH with the measurements from a series of observations of Gamma Virginis.
Provides JH with information and advice about large lenses, which JH is considering for a Cape of Good Hope Observatory equatorial telescope.
Describes some available glass discs, which might do for making lenses for a large refracting telescope [see GA's 1843-8-30].
A notice of meeting of the Standards Committee, together with an indication of business to be conducted at that meeting.
Does not believe that a magnetic congress held at this time would be productive or representative; a better job could be done by letter.
Expands on GA's proposed letter writing scheme in place of holding a magnetic congress [see GA's 1844-7-30].
A note accompanying a draft of the report on magnetic observations to date at British stations, and a circular to be sent out.
Has sent on the draft report on magnetic observations to W. S. Stratford for completion [see JH's 1844-10-13].
Accepts JH's invitation to attend the meeting [see JH's 1844-11-1], and offers JH accommodation for the night.
Comments on the various responses to the circulated questions about magnetic observations [see JH's 1844-12-5].
Describes testing William Simms's object glass and then gives details of the equatorial mounting GA used; offers to send carpenter to JH to construct mounting so JH can test object glass [diagram].
Is anxious to know whether JH has used William Simms's object glass, and seeks JH's opinion.
Provides JH with the latest Royal Observatory values for Gamma Virginis [see JH's 1845-9-30], and advises JH to change his method of measuring double stars.
Still trying to solve the problem of jogging Robert Peel's memory [see JH's 1845-10-8].
Thanks JH for his report on William Simms's object glass trials [see GA's 1845-9-29], together with some other astronomical matters, including reference to a letter from F. W. Bessel.
