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.
Hopes that JH will maintain the road from the canals to Hawkhurst as SM possesses a right of way over it.
Acknowledges with pleasure JH's kind note. Owes much to JH's book in the chapter on experimental methods. JH will doubtless find Auguste Comte's book worth reading. Would like a note of any errors in JM's book.
About the health of Caroline Herschel, and other news from Hanover.
Would like JH to peruse HM's work and publicize its considerable use to Robert Graham.
Reports on GM's health and immediate travel plans.
Gives his own ideas concerning the origin of diamonds and would like JH's comments. Would also like JH's views regarding the phosphorescent light that plays at night over the magnesite excavations.
Has now heard that the explosion at Dover is to take place on Thursday. Hopes to see JH there. If not, will call on him at Hawkhurst.
Has ventured on the risks of an election to the R.S.L. and would like JH's support and influence with those on the Council. Was prevented from visiting Dover. Sails for Canada on 4 Mar.
Should JH be attending the B.A.A.S. meeting at Cork, hopes he will visit WP and spend a few days with him. Gives news of the progress of his great telescope.
Explains how it comes about that GW is looking for a position at the British Museum.
Talks about British Museum business, including the purchase of fossils and the hiring of George R. Waterhouse.
Expresses GW's concern if the British Museum were to require him to pledge to do no remunerative work outside what they would pay GW to do. GW, however, is prepared to make that pledge, if necessary.
JH's account of a comet reminds WT of a strange sighting many years ago. Comments further on improvements in photography, both those made and those needed.
Sends deeds already signed by J. J. Guest. JH should sign and return them. [Annotation by unknown hand: Mrs. Hollier's marriage and settlement.]
Describes observing of comet that evening.
More on confused systems of star magnitudes used by Thomas Henderson.
Suggests 'amphitype' as name for JH's process whereby same picture can go from negative to positive. Further comments on comet sighting, and on some improvements to Daguerreotype.
Comments on JH's positive calotype. Suggests comet may be return of (J.-D.) Cassini's comet of 1668. Gives theorem for finding parabolic orbit of comet if two observations are made in the ecliptic.
Announces election of Marquis of Breadalbane [John Campbell] as lord rector of Marischal College for coming year. Thanks for JH's advice to college senate.
