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.
Preparing for total eclipse of sun in 1868. Conferred with William Huggins about making spectroscopic analysis of red protuberances. Asks JH's opinion.
Will not apply to government for money to purchase telescope for observing [1868] eclipse. William Huggins believes that larger telescope is needed. Would JH's son [John] make these observations [for R.S.L.]?
Asks JH's opinion on matter of purchase of expensive telescope for solar eclipse (1868) and other observations by William Huggins.
Sends list of tutors at Trinity College contemporary with William Whewell; comments on telescope needed for eclipse viewing.
About some instruments to be taken to India by JH's son John.
Wrote to G. G. Stokes and agreed to seek the permission requested by R.S.L. Will arrange for personal interview with Stokes. Is this 'independent of [Charles] Tennant's proposal'? Outlines survey plans if given charge of large instrument.
Response to a letter from JH to G. G. Stokes [1867-5-5] seen by GA, on the problem of the effect of the telescope on illumination from a light source, especially related to a solar eclipse.
Asking for answers to specific questions in hydrodynamics, which may be related to a future patent application.
Note accompanying a copy of a paper by AS.
Returns JH's letter from G. G. Stokes about eclipse spectroscopy; GA has written to Stokes as well and encloses a copy of this letter.
Provides JH with best definition that GA has available for the gallon [see JH's 1867-11-3], noting that methods for establishing standards are revised, even if the standards supposedly are not.
Writes to acknowledge receipt of letter [see JH's 1864-11-25], but it will take time to work through JH's calculations carefully.
Thanks JH for his useful letter [see JH's 1867-12-2]; it will be of value to the Commission on Weights and Measures.
Thanks JH for his clear letter [see JH's 1867-12-3] about the pound weight standards.
Wants to send JH and [John] Stewart memoirs of her father, [Josiah] Quincy. Praises JH's Iliad translation) and his Cape Results. Introduces her nephew, General [?] Quincy.
Sent her father's [Josiah Quincy] memoirs to London as JH directed. Praises JH's Iliad translation, Cape Results, and astronomical career.
Asks if JH received a copy of the memoirs of her father [Josiah Quincy]. They will be a 'valuable addition to the history of the U.S.'
Thanks JH for translation of [Friedrich] Schiller's 'The Walk.' Reform bill will again be before the House tomorrow. Denounces mischief of the Radicals.
Asks JH to sign memorial for [John?] Stevelly. Discusses excited reaction to [Michel] Chasles claims regarding Blaise Pascal and Isaac Newton.
Will forward information on spectrum analysis when he receives it. Asks if JH is interested in studying the photochemistry of the sun during the upcoming eclipse.
