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.
Regarding F. W. Bessel's doubt concerning the law of gravitation.
Thanks for prompt reply. Does know something about blood and circulation, but may not have expressed himself clearly. Thinks Michael Faraday has made important discoveries in magnetism and electricity.
Comments, after delays due to busyness, on JH's queries on the calibration of actinometers and gives results of experiments.
About observations of the seventh satellite of Saturn, and using William Parsons' (3rd Earl of Rosse) 'machine'.
Agrees wholeheartedly with JH's recommendation for his paper. Will rewrite it if necessary. Hopes JH will produce a second edition of his work on finite differences.
As secretary of newly formed 'Mechanic's Institute' in Slough, HW invites JH to preside at 18 Feb. meeting.
Discovered a telescopic comet in Cepheus. Gives readings.
Encloses application for meteorological and magnetic observatories from governor of New Brunswick. May establish observations in all colonies for limited time. Puzzled over [John] Lefroy's results from Athabasca.
Wishes to use remarks JH made at Kew Observatory in 1846 for a Royal Society publication. Asks JH to read transcript for accuracy.
As disturbed about the medal situation as JH [see JH's 1847-2-8]; the solution seems to be to award two medals.
Is sending papers, from an American, for JH's opinion.
Asks JH to suggest candidates for a professorship at the South African College.
As secretary, GY requests JH's presence at first soirée of Whittington Club [for journalists]. Will JH accept election as vice president?
Reports to JH on the discussion, about the medal problem, at an R.A.S. meeting [see JH's 1847-2-11].
Regarding his Copley medal, has written a letter of thanks to the Society. Does not doubt that the new planet will be discovered.
More information on the activity of the R.A.S. in trying to resolve the medal problem [see GA's 1847-2-13].
Has been preparing famine food, such as hay biscuits.
Apologizes to JH for worrying him about the printing of J. J. L. Lalande's Catalogue of Those Stars in the Histoire céleste française....
Discusses the cost of printing and publishing J. J. L. Lalande's Catalogue of Those Stars in the Histoire céleste française and of N. L. Lacaille's Catalogue of 9766 Stars in the Southern Hemisphere [for which JH wrote the Preface]. Hopes to have both books published by the end of April.
Copies of 1847-2-20 letter will be sent to observatories utilizing actinometers. Earlier series will be replaced with accurate figures. Suggests method to measure temperature in actinometers.
