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.
Recent work and money expended on CB's machine. News of town. James South intends to sell his instruments.
Observed two known satellites of Uranus, confirming William Herschel's observations. States, 'I am sure there are more than two.'
Remarks on Saturn and measurable discs of stars.
Sending the Gold Medal awarded to CH by the Astronomical Society and also a pair of bracelets from his mother; will send the indexes later. Just erected James South's large equatorial.
Is glad Thomas Brisbane was in the chair at the meeting. Will be pleased to join the party on Friday. The Parramatta observations. Someone to supervise their publication. His own recent observations.
Accepts invitation to WF's party on 19th, but will miss reading of Adam Sedgwick's and R. I. Murchison's paper. Chemical composition of 'Fish limestone.'
Response to a positive letter from ME, which was sent in response to JH's sending her portions of his essay on light.
Sending DB a draft of a paper; comments on quality of a chromatic lens (that of [Charles] Tulley's telescope using Pierre Guinand's glass).
Thanks for remainder of WH's essay on 'Systems of Rays.' Recalls error-ridden copy of JH's Light given to WH; sends correction. Wishes to propose WH for membership in Astronomical Society.
JH played no role in the awarding of an Astronomical Society medal to CH. Sent to CH a few copies of JH's Light. His catalogs of double stars and nebulae are progressing well.
Describes the tests JH made on a small glass prism of not very high quality, which JH has left at the Royal Institution.
Declines offer by Archbishop of Canterbury to join provisional committee to govern newly proposed King's College.
Charles Babbage has every reason to be grateful for FB's letter to the Times. Richard Sheepshanks and the observations. The ring of Saturn. Has been observing lots of Wilhelm Struve's double stars.
Has found some errors in the sheets of computations HK sent. Lists these. Comments on astronomical work of [William] Richardson and on the reading of 'The repeal of the Longitude Acts Bill.'
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.
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.
Discusses atmospheric refraction, Francis Bacon's distinction between argument and testimony, and the manner in which the Board of Longitude was dissolved.
Further regarding Richard Taylor the printer. Reports on observations of Mars by William Pearson. JH's new micrometer is aiding his observations of double stars.
[Richard] Taylor is very anxious that the Astronomical Society reconsider its decision to discontinue his services as printer of the Society's publications. Suggests presentation of a gift to William Stratford for his services as secretary of the Astronomical Society.
