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.
Is sending a packet and several letters. Events at the last council meeting. Will read Ernesto Capocci's letter at the next meeting of the R.A.S.
Is sending some drawings of the comet, which had been mislaid. Thomas Maclear's paper is being referred to JH for his corrections. Will discuss which drawings are to be included.
On the variability of the star Alpha Cassiopeia.
Has marked Thomas Maclear's paper and returned it to Thomas Galloway.
Has been unable to carry out many observations so has not written. Hears Kew Observatory is vacant with the death of S. P. Rigaud, and would like JH's support for his application for this appointment. Has been approached about taking charge of the projected Manchester Observatory. Has written to G. B. Airy for support.
JH's letter has gone a long way to destroying his hopes for success at Kew. A great pity that the Observatory could not be put to good use. Must soon obtain employment more congenial to his tastes and this would seem an ideal position.
Encloses statutes of General Shipwreck Relief Society, which JH is interested in joining.
Has been getting information about the area with a view to buying a house there; met J. W. Lubbock and was very shocked by Lubbock's unhealthy appearance.
Translation of a work by C. F. Gauss and Wilhelm Weber will provide the information requested. Hopes [William Cranch] B[ond] will participate in magnetic observations. Explains 'Copper Dampers.'
Comments on several approaches to fixing images on paper, especially using pure water as a fixing agent. Has developed a new sensitive paper but is keeping it secret until perfected. Is leaving for Continent on 1 May.
JH reports his discovery of a highly sensitive paper. Tint continues to deepen with time, as bromine does not. Not prepared to reveal process at present. Is off to Paris.
Forwarding Thomas Maclear's paper on N. L. Lacaille's Stations for JH's Report. Would he also mark any unnecessary passages or drawings.
