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.
Has JH's memoir on elliptical orbits of Saturn. Asks for JH's indulgence with lack of astronomy in annals. AQ has no big instruments. Has planted thermometers for experiments. Finally received transit instrument from [H. P.] Gambey.
Even though JH has not written, AQ has received news from JH's compatriots. Asks about JH's health. Has not really used equatorial. Continues work on terrestrial magnetism and includes observations. Asks if JH has received last part of translation of JH's work on optics.
Wonders if JH has received AQ's letters and works sent to the Cape. Sends more. Has been doing meteorological observations. Will send some if JH wishes. Mural circle and transit instrument finally in place. Problems with equatorial; therefore missed Halley's Comet.
Still has not heard from JH. Has put much effort into horary observations of solstices and equinoxes. Sends JH articles by AQ on temperatures of earth. Will send magnetic observations.
Expresses regret for not writing earlier. Thanks AQ for meteorological observations. Has complete series of observations from March 1835 to December 1836. Thanks AQ for reports on papers sent. Will depart in early 1838 and requests duplicates of all observations sent: one to England, one to the Cape. Apprises AQ of JH's work on double stars and nebulae.
Attached circular from Meteorological Committee of South African Literary and Philosophical Institution stating a change from 36 to 24 hours of hourly observation at solstices and equinoxes. Letter to AQ thanks for great work and requests AQ continue.
Welcomes JH back to England. Proof that AQ never ceased thinking of JH is that AQ never quit his horary observations. Has sent books to R.S.L. for JH. Has restarted his notices on meteors. Is determining their longitude in relation to Greenwich. [Richard] Sheepshanks brought AQ JH's portrait and bust.
Thanks for two letters. Updates JH on observatories participating in horary observations. Proposes to reduce observations. Sends second part of Brussel's annals and other works. Discusses a phenomenon on 10 August. Mentions several observations of the Aurorae Borealis.
Sends latest publications. Has received highly surprizing letter on meteors by Mr. Wood. Discusses 'famous apparitions.'
Thanks for duplicates of horary observations. Requests that AQ and his associates cease them after December 1838. Questions 'whether any and what' corrections are applied to observations. Has successfully seen second satellite of Saturn.
Has received JH's letter of 29 October. No need to thank for meteorological observations. Done in interest of science. Sends measurements of December 1837 and other bulletins. Asks JH to send his extra copy of AQ's Correspondence mathématique of July 1838 to [J. D.] Robertson. Asks more about satellites of Saturn. Thanks for information on meteors.
Thanks AQ for meteorological observations for September 1838 and other materials sent. Singles 12 and 13 November as extraordinarily clear. Observed a 'paucity of shooting stars' and an Aurora Borealis.
Discusses observation of meteors. Sends observations of last solstice and details of that night's constellations. Offers results of observations of occultation of Gamma[?] Tauri[?].
Sends continuation of Belgian meteorological observations. Just finished magnetic observations. Plans to continue certain ones. Regrets being alone, without aids, 'in front of the transit instrument, the mural circle and the equatorial.'
JH's brother-in-law John Stewart, who is delivering this letter, seeks admission to a printing establishment. Asks AQ to aid JS. Lists recently received letters. Glad that AQ has [C. F.] Gauss's apparatus. Discusses an experiment in photography.
Addresses a few last words before departing for Italy with his wife. Sends 3 memoirs just published. Will be in Paris to observe meteors. Proposes to redo terrestrial magnetism observations in Italy.
Is comparing 'points and measures' of new stations with [François] Arago. Also busy with daguerreotypes. Thanks for encouragements. Has necessary instruments for meteorological and magnetical observations. Mentions work done and astronomers met on Italy trip. Discusses Prince Albert.
Herschelian Telescope Song in English and Latin, translated by [T. I. M.?] Forster into Latin. Requiem of 40-foot reflector sung at New Year's Eve 1839-40.
Sends publications from Royal Academy and Brussels Observatory. Asks 'particular indulgence' for one about vapors. Is now able to do observations required by R.S.L. A Gauss instrument has been mounted. Gives times of observations each day. Continues horary observations.
Still waits for the instrument that Edward Sabine had built. Wishes to make actinometer observations but has no instrument. Asks JH to have one made. Sends observations from Italy trip to Sabine to present to R.S.L. Continues horary observations.
