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.
Sends JH a mathematical theorem.
On the deviation from the perpendicular of falling bodies.
JH's letter grieves him, but he will convey his decision to the Trustees. Has just heard of the death of the Archbishop [of Canterbury, William Howley].
Has written a letter to Mrs. James Maclaren and enclosed three orders of admission to the British Museum.
Sending a letter on the Orthography of the African language from a friend of his, the Rev. Henry Venn. Would be grateful if JH could help him.
Does JH intend visiting the R.S.L. on Thursday and probably the R.S.L. Club dinner on that day? If so, will he breakfast with him?
Encloses a letter from W. J. Burchell, the African traveller, showing the variability of Argus. Has added a 10 foot telescope to the instruments at the Observatory.
Apologizes for having questioned GA's proposal [see GA's 1848-5-6], which is very good and should work well.
Presumes they are at Adam Sedgwick's. Supposes they will come to Broxbourne by the 11 o'clock train from Norwich and will arrange for it to be met. Expects a new theory of the earth's crust from JH. Mrs. Jeff[re]y is seriously ill, which delays the Jeff[re]ys at Haileybury.
Louisa and Johnny [Herschel] are well. Called at India House to see Mr. Hooper. Gives requirements of the various examinations and thinks Willy [Herschel] would do well to stay with [Charles] Pritchard, while Johnny can remain and study at home.
Col. Ouseley had a son at Addiscombe. Has ascertained the relative value of the various branches of study in the final examination. Gives table of values. Hears that military drawing puzzles some. Children are well. If Johnny [Herschel] draws as well as Louisa [Herschel] at 14 he will do well.
Wants to send JH a remembrance which his Aunt Caroline wanted JH to have. The obituaries in some of the papers are inadequate. The astronomical journals need to be provided with suitable information about Caroline Herschel.
Thanks Margaret Brodie Herschel for a gift. Talks about some legal matters related to the death of JH's aunt Caroline Herschel. AK is much concerned with political turmoil around her. Apparently Dr. Mühry died soon after the death of Caroline Herschel.
Concerned about the sending and receiving of some of Caroline Herschel's bequests to JH. AK also talks about arrangements for some other people following Caroline Herschel's death.
Has sent his observations on Saturn and Neptune to the R.A.S. and encloses a copy for JH. Weather has been unsuitable for many observations recently. Has not heard of any observations of a second satellite of Neptune.
Has received a letter from W. C. Bond of the Cambridge Observatory (U.S.A.), who speaks of the satellite of Neptune. Bond also sends details of the stars around Orion. Relates his own work on the specula of telescopes. Intends to submit a paper on this to the R.A.S.
Outlining the apparent controversy between himself and W. C. Bond over the discovery of the satellites.
Further regarding W. C. Bond's discovery of the Neptunian satellites.
Criteria for deciding who can claim to be the discoverer of the satellite. [This letter marked 'not sent on second thoughts; see RS:HS 23.41 for letter sent.]
Asks for CW's contribution to the Admiralty's scientific manual.
