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.
Made a 'mess' of the tidal observation and meteorological observations that he took earlier in the week.
Too ill to attend the South African Institution meeting; asks JH to turn in the packet containing TM's and JH's meteorological observations.
Actinometer observations during the eclipse.
Finishing his copy of the panorama taken from the summit of Paarl rock. Needs TM's star reductions as soon as possible.
Thanks TM for the right ascension reductions. Saw the comet [Halley's] last night, but it was dimmer than before.
Asks for TM's barometer and thermometer readings for 20-28 September.
Feeling very ill. Discusses adjustments to TM's transit instrument.
Measurement of h Centauri.
Found the 'real' h Centauri; unsure what star is the 'false' h Centauri. Saw the largest sunspot that JH has ever seen. Saddened to learn that TM's son [George] is seriously ill.
Wants to invite members of the Beagle to dinner.
Sending the chronometer.
Polishing telescope mirrors.
Asks TM to attend a meeting of the Cape of Good Hope Association for Exploring Central Africa.
Asks TM to set JH's chronometer and barometer.
Oppressive heat prevents JH from visiting. Sending a list of furniture from Major John Ross's house, which JH definitely will purchase.
Saw a 'small round perfectly defined body' last night that looks like a planet.
Found a 'very fine' planetary nebula. Unable to learn anything conclusive from TM's microscope readings. JH's observation tower is erected and is currently being plastered.
Happy that TM is handling his facial paralysis so well; JH believes that it is due primarily to anxiety and overwork.
Gives location of a planetary nebula.
Predicting poor weather, JH advises TM not to go to the Grove tomorrow.
