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.
Details about JH's upcoming voyage from Portsmouth [to Cape of Good Hope] and about an expedition going north from the Cape into Central Africa.
Thanks for sending results about conical polarization and introductory lecture on astronomy communicated through Francis Beaufort. Had hoped to send WH JH's yet to be printed catalogue of double stars.
On learning that JH's trip to the Cape will be delayed somewhat, invites JH to dine with R.S.L. Club in October.
Praises JH's Prelim. Discourse and work in general. Wishes well at the Cape.
About observing binary stars. JH has decided not to accept the offer of passage on a war ship to the Cape of Good Hope, as he wishes to be beholden to no one for the results of the expedition.
Congratulates JF on obtaining, after some difficulty, the Chair of Natural Philosophy at Edinburgh. Accepts offer to discuss meteorology with JF's relation Leslie Melville[?], and hopes to mention his actinometer.
Wishes JF well in [Edinburgh] and leaves addresses where JH may be reached [at the Cape].
Asks JH to review a publication RS was preparing. Comments on James South's claim concerning supposed defects in the telescope made for him by Edward Troughton. Suggests JH intercede with the government to get it to support G. B. Airy's reduction of the Greenwich planetary observations.
JH preparing for his journey to Cape Town. Compiling a catalog of nebulae and clusters. Sending to CH a comparison of a new set of elements of Gamma Virginis and a set of observations of it from 1720-1833; JH asks CH to send a copy to Carl Gauss.
Sent to CH JH's fifth catalog of double stars. JH will send to CH his new nebulae observations very soon.
Ready to embark to Cape Town; JH expects to arrive at the end of January. Sent out the last proof sheet of JH's nebulae catalog last night.
Feeling simply 'dismal.'
Wishes JH well on his upcoming trip to the Cape of Good Hope. Asks JH to study the lower part of the Scorpion, for William Herschel was mystified by the 'uncommon appearance of that part of the heavens.' [Written as a postscript to a letter by Margaret Herschel.]
Rev. Humphrey Lloyd's paper on conical refraction agreed with WH's conclusions.
JH reports the birth of his son William James Herschel.
JH explains how CH's money will be allotted to her while JH is in Cape Town. Margaret Herschel writes CH a note describing JH's new son William.
Mentions to CH that 2000 of the nebulae and all of the engravings are printed.
Sailing to Cape Town, JH reports sighting an English ship.
Asks for reply to specific questions regarding telescope quality and price [see JH's 1833-8-29].
Will be able to receive JH during Cambridge trip.
