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.
JG is worried about the health of his daughter.
Did not pass near JH's place when he came home; otherwise he would have returned JH's mirror. Returns next Monday and will be pleased to call if JH can offer him a bed. The storm did no great damage here, but at Chislehurst it turned a house inside out.
Informs JH that JI had been warned off, by Stephen Lee, from writing about the figure of the earth because that was JH's territory.
Assures JI that JH could not, and would not, utter such threats, and has sent Stephen Lee a copy of this letter [see JI's 1828-7-10].
Sends Knowles's paper for his comments. The Board of Longitude has now been officially dissolved. Hopes the R.S.L. will not take on its work unless well paid by the government. Answers to JH's queries regarding the Nautical Almanac and other works of the Board of Longitude. Present time not good for state recognition of science.
Is engaged in preparing a new popular cyclopaedia, and would be pleased if JH would contribute an article on Light.
Sees no objection to JH publishing a larger work on Light later if desired. Gives the names of some of the contributors to the Cyclopaedia.
There is no truth in SL's statement to James Ivory regarding work on the figure of the earth belonging exclusively to JH. Has written to Ivory stating the facts of the misunderstanding.
When he last saw James Ivory at the British Museum, no mention was made of JH's name. Thinks the remarks of Ivory are caused by mental disease.
Has been overwhelmed with work, which accounts for the delay in writing. Thanks for communications. Both are now printed. Comments on some of the points raised.
JH very upset at the government abolishing the Board of Longitude; has many questions as to what will happen now.
Is sending the letter with the British ambassador [Augustus Foster] to the Court of Turin; Foster is much interested in science and in meeting JH. GP will be sending additional work that GP has done, and indicates further plans.
Wants to meet with JH, and needs more money to continue work on Charles Babbage's calculating machine.
Is concerned about the rapid rate of expenditure of the money on Charles Babbage's calculating machine. Recommends a reasonable rate of expenditure until Babbage returns home, which should be in about four months.
Suggests that phenomenon in observing Jupiter satellite was an optical illusion. Asks WS to observe spots on Mars to confirm observations of William Pearson. Asks WS to contribute to W. S. Stratford memorial.
Has been contemplating a larger work on Light, but thinks he may be able to write a shorter, more popular work for the Cabinet Cyclopaedia. Wonders who the other contributors will be.
Asks JH to report how James South's telescope performs. There was a defect in the settings of the telescope. Hopes JH's method of eliminating chromatic aberration improves the microscope.
Sends WS JH's 'Light' published in the Encyclopaedia Metropolitana. Mentions recalibration of his magnitude measurements of small stars near other small ones. Comments on results in WS's paper concerning Saturn's ring. Confirms sighting of 'well defined, equable, planetary disk.'
Lists contents of a letter sent on 1828-7-6. JH's Light and third catalogue of double stars sent. Details of nebulae included.
Requests permission to translate JH's work on light into German.
