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.
In case he has not received a letter from Berlin he sends details of the planet of U. J. J. Leverrier.
Hopes his friends will support the publication of his Barometrographia, which will be exhibited at the forthcoming B.A.A.S. meeting.
Will distribute the prospectuses of LH's book as desired, but regrets he will be unable to subscribe for a copy himself as its price is too expensive for his means. Pleased to hear of his good health.
Regarding Benjamin Peirce's Elementary Treatise on Sound. Can lend him his own copy if JH has no copy.
Talks about considerations to be taken into account when building telescope specula, especially large ones.
Details of WL's observations of the seventh satellite of Saturn.
Believes that the observations WL has made are quite sufficient to establish the existence of the seventh satellite of Saturn.
Would like to see C. F. Schönbein's invention tried but has not the means to afford any assistance at the moment. Understands that Edward Sabine is to introduce Schönbein to the Master General of Ordnance, so he will be in good hands.
Protests erroneous impression in today's report of JH's conduct at closing meeting of B.A.A.S. Does not know what gave rise to T. D. Morris-Stirling's remarks regarding electric telegraph. Witnesses confirm that JH did not malign British science. [JH annotation: Printed 21 Sept. 1846.]
Received copy of TM's letter to the Times and sends copy of JH's letter to the Times. Recounts words that JH and TM used; wishes 'foam' had been used instead of 'scum,' to prevent misunderstanding [at B.A.A.S. meeting].
Invites JH to join SB and Mr. Bold at 'our stable' tomorrow evening. Hopes [J. B. A.] Dumas will arrive from Paris then.
Sends results of RM's experiment on wave motion and earthquakes that RM will report at B.A.A.S. meeting in Southampton. Proposes new committee to implement RM's project.
[Marked 'Private.'] Encloses copy of TM's letter to the Times responding to news report of TM's altercation with JH and [T. R.] Robinson at B.A.A.S. meeting.
Challenges JH's letter in the Times today justifying JH's remarks at B.A.A.S. that Charles Wheatstone invented electric telegraph. Believes Wheatstone 'pilfered' invention from Mr. Baines.
Returns two papers, which had been missent, thus preventing JH from communicating them at a meeting.
To help RM, who must speak about [F. W.] Bessel, writes of Bessel's astronomical accomplishments.
On fitness of Michael Faraday, as a chemist and physicist, to chair B.A.A.S. section. Remarks on [H. C.] Oersted's identifying electricity and magnetism, and connection between Oersted's and Faraday's work. Further comments on Faraday's work, and on instances of rash observation ultimately proving correct.
WS has been quite ill for nearly a month. Sends the rest of the proof sheets of the catalogue [J. J. L.] Lalande's Catalogue of Those Stars in the Histoire céleste française... or of N. L. Lacaille's Catalogue of 9766 Stars in the Southern Hemisphere.]
Is about to leave for a journey through Belgium and Germany for the purpose of studying collegiate education on behalf of the Irish government. Would welcome any letters of introduction from JH.
Thanks JH for spotting error in a publication about the Edinburgh Observatory. Discusses 'the planet that is expected to be found beyond Uranus.' Asks JH to help him send astronomical news to Thomas Maclear.
