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.
Has received GA's manuscript instructions for ship's officers [see GA's 1848-1-9]; there is no hurry on the remaining pages.
Thanks GA for his contributions to some material JH is compiling; asks about date of Board of Visitors meeting.
Comments on all of GA's instructions for ship's officers [see JH's 1848-1-10], mostly suggesting some additions about meteor showers.
Thinks the building changes proposed [see GA's 1848-1-21] are fine; explains JH's position on the whole matter.
JH comments on quality of Georg Merz object glasses.
Agrees that some of JH's suggestions about meteor showers were probably unnecessary [see GA's 1848-1-29].
Is aware of T. J. Hussey's drawings [see GA's 1848-2-1]; needs information about P. A. Hansen's lunar theory for an appreciation JH is to provide.
Surprised by GA's unhappiness with George Merz [see GA's 1848-2-17]; suggests GA seek information from Thomas Maclear at the Cape, who is getting a new telescope from George Merz.
Willing to let GA choose the best objective lens [see GA's 1848-4-5]; then JH offers another possibility; all are ill at Collingwood.
Does not believe that GA's proposal [see GA's 1848-5-4] will work.
Apologizes for having questioned GA's proposal [see GA's 1848-5-6], which is very good and should work well.
Agrees that no requests for additional observations should be made of Thomas Maclear; Admiralty Manual is about to be printed [see GA's 1848-7-15].
Forwards a letter about the Venus parallax expedition [see GA's 1848-9-21], and adds some comments.
Reports that William Lassell has written to say he has discovered the 8th satellite of Saturn.
Personally would like to have F. W. A. Argelander's work printed [see GA's 1848-9-13], but will need to get a wider opinion; also asks about sharing money available from the Admiralty [see GA's 1845-10-24].
JH has revised his account of the moon's motions given in JH's Treatise Astr. in preparation for JH's Outlines Astr.
Remarks in response to GA's 1848-10-4..
Regarding Isaac Newton's theory of the motion of the moon's apse. Concerning the reliability of J. H. Seyfforth's theories. Status of the Ipswich Philosophical Society.
JH begs to differ with GA and Isaac Newton on the moon's motions [see GA's 1848-10-13]; warns GA against accepting J. H. Seyffert's work as accurate.
Still arguing that Isaac Newton is not correct concerning the moon's motions [see GA's 1848-10-24].
