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.
Found Encke's Comet the night before last. Has not had a chance to see Halley's Comet. Will JH come to the Observatory? There are no fleas.
Is glad JH has given his opinion to Francis Beaufort on the subject of observations of the first class. Encke's comet is invisible in the 14-ft. within the range of 10 degrees. Last two nights were very favorable. Has seen Encke's comet three times, and it appears just as he saw it in England.
Is intrigued by the apparent displacement of several planetary nebulae from the positions found in the catalogues of other observers. Does not know what to think.
Discusses printing costs. Heard that Halley's Comet was seen with the naked eye in Cape Town; JH is excited about his own prospects of seeing the comet.
Still struggling with the problems inherent in using the mural circle; the comet has apparently been seen by JH's mechanic, John Stone, prior to having been sighted by TM.
Busy taking the means of TM's reduced star observations. Angry that John Stone and James Rance saw Halley's Comet and never told JH.
Warns that 'a share in a new planet is advertised and that those who will bid must be on the alert.'
Hopes that TM can explain the errors in JH's star reductions. Saw Halley's Comet last night; comments that 'its tail was again fine and head very bright.'
Asks TM to measure the position of some stars that are difficult for JH to observe.
In some places, Halley's Comet will be seen in or near its perihelion during the solar eclipse.
Actinometer observations during the eclipse.
Asks TM to come over and to select the trees for the Time Ball.
Asks TM to inquire of Captain F. W. Grey of the Jupiter about N. L. Lacaille's mural quadrant, which was supposedly aboard the ship two years ago.
Is TM planning to go to Paarl?
Uncertain when they are traveling to Paarl.
Finishing his copy of the panorama taken from the summit of Paarl rock. Needs TM's star reductions as soon as possible.
Invites TM to come see Halley's Comet in JH's large reflector. JH reports his observations of the comet.
Sends a list of additional stars to be measured for JH to use as standards.
About an anomaly in one of JH's lists of observations.
Calculates the location of the comet [Halley's].
