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.
Was interested to receive the information regarding another missing nebula; would like to mention it at the R.A.S. The late George Bishop's observatory is now being rebuilt at Twickenham. Will return N. R. Pogson's table of Julian dates tomorrow. Has adopted the first of JH's suggestions.
Returns N. R. Pogson's tables. Has received a communication from [W.?] Lummis concerning a dark spot on the sun's disc. Has been unable to make any calculations yet.
Sending JH some crystals for examination. The quartz crystals show spirals. Invites JH to supply information concerning the crystals.
Sends sketch of reflecting camera and describes its composition. Can now make reflectors under 7 inches very inexpensively.
Informs JH of his grief over losing his son and his wife. His other son has left the military and now is helping AQ. Talks of Prince Albert's death. Asks JH not to forget AQ.
Condolences on death of AQ's wife and son. Having lost a daughter, JH sympathizes. Discusses merits of Prince Albert. Lists Belgian Academy memoirs possessed to date. Mentions work on a general index catalogue of nebula. [J. R.] Hind's nebulae and others are disappearing.
Remarks on JT's papers on radiant heat and related role of moisture. Will send requested sample of rock salt. Explains difficulties using it and hopes JT will have better success, perhaps even repeating JH's experiments.
Finds JH's approval incredibly gratifying. Thanks for gift of rock salt. Is sending unscientific book; trusts JH's interests are broad enough to appreciate it.
Thanks for volume on physical geography and for encouragement at start of GS's career. Hopes JH will approve of GS's latest work.
Is sending first part of observational data for nebula catalogue [see GA's 1862-3-31].
Forgot, in earlier note [see JH's 1862-4-2], to indicate agreement with GA's suggestions [see GA's 1862-3-31].
Material sent by JH [see JH's 1862-4-2] arrived safely.
Acknowledgment of receipt of more material from JH [see GA's 1862-4-3].
Needs to know, from JH, the date of the nebula observations [see GA's 1862-4-9].
Responds carefully to the question of observational, and reduction, dates [see GA's 1862-4-12].
Acknowledges receipt of more material from JH [see JH's 1862-4-13].
Has now sent the last of the nebula observations to be reduced for printing [see GA's 1862-4-16].
Sends JH a copy of the form to be used for reduced observations [see JH's 1862-4-17].
Approves of form for reduced observations [see GA's 1862-4-24] and sends GA payment against expenses.
Acknowledges receipt of payment [see JH's 1862-4-25]; asks for final approval of printing structure for the nebula catalogue.
