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.
Outlining the circumstances in which J. N. Vallot was elected an Associate of the Astronomical Society. Has only received one letter from Vallot.
The Miss Edgeworths will prolong their visit until Friday in order to visit Slough. George Dollond has sent the radii of the crown lens. Will JH breakfast with the Katers on Friday?
The Miss Edgeworths have changed their plans again in order to visit Portsmouth, but will arrive at Slough on Sunday morning. Hopes the Herschels can still breakfast with the Katers on Friday.
Sends a copy of Volume 1 of the Transactions of the Astronomical Society, and makes arrangements for future volumes.
Thanks for sending your catalogues. Requests duplicates. Has made annotations indicating the 'quantity which Mr. [F. W.] Bessel's Instrument places the stars to the south of my determinations.' Cannot yet explain discrepancy. Unable to determine a parallactic shift for Alpha Lyrae, Alpha Aquila, or Gamma Draconis.
Thanks JH for extract from a letter from [J. J.] Littrow. Discusses in detail positional determinations of various stars he has made, attempting to determine whether errors of either observations or computation have entered into his results. Reports that in general there is substantial agreement between determinations made by JP and those made by John Brinkley at Ireland's Royal Observatory. Mentions solar observations at Greenwich.
Mentions meeting [W.] Herschel in 1816. Recalls receiving catalog from Caroline Herschel, which he then gave to the Munich observatory. Looks forward to meeting JH and 'sharing love of truth.' Sends chemistry and physics papers. Discusses code for electromagnetic signals and its origin.
Will not be able to pay a visit as children have whooping cough. Has been demonstrating his calculating machine. Hopes to see him at the Greenwich visitation.
JH has been appointed a Lay-fellow. It entails no duties. The present body regards it as an honor to retain JH's name.
Further regarding the transmission of papers abroad. Encloses a copy of his own paper on the formula of J. J. Littrow. Astronomical matters.
Received MB's notice that JH was appointed fellow of Saint John's College. Will visit Cambridge if William Herschel's health permits.
Examine reflecting theodolite by [?] Schenk, now at Edward Troughton's. Arrangements for Madeira expedition. James South is willing to make observations there. 'Bowdich (the African)' is now at Teneriffe or Madeira and needs employment. William Herschel's health.
Requests corrections on a paper JS was publishing with JH. Urges JS to use less excessive language.
Thanks for the publications sent; lists materials JH is sending JL. Asks about quality of Josef Fraunhofer's large telescopes. JH read part of JL's letter of 2 Jan. 1822 at Astronomical Society meeting. Discusses proper motion of sun, JL's work on latitude of the pole star, observatory clocks, micrometers, and the Cambridge Observatory.
Discusses the pros and cons of GE's proposal that [J. C.?] Schenck, a Swiss maker of optical instruments, set up a business in London. JH is not sure that JH ascended Mt. Rosa, but is certain of JH's barometric reading. Interested in GE's method of estimating air temperature.
Would like very much to see JH as soon as possible. Has an instrument of [J. C.?] Schenk to show him. There is one on the way to him now from Paris.
Cannot leave the instrument with Edward Troughton later than Saturday. Perhaps Troughton had better leave the instrument in the box until GE calls.
[J. C.?] Schenk has reason to be grateful to JH for all his assistance. Schenck's friends can now judge whether it will be expedient to bring Schenk to London to set up in business. Awaits anxiously the verdict of Edward Troughton.
The comet is not visible. All is ready for its observation. How is the Cambridge observatory progressing? Comet still not visible. Wishes he had a good telescope.
Has received letters from the Admiralty, which have allayed all his previous distress. Is to receive two telescopes. Weather has been unsuitable for observations.
