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.
Urging JH to recommend the services of Lieut. James Bance to Gilbert Elliot (2nd Earl of Minto).
Too ill to attend the South African Institution meeting; asks JH to turn in the packet containing TM's and JH's meteorological observations.
Expects an occultation of Jupiter this evening. Hopes JH enjoyed the fine cool breeze of last evening. Another English vessel reported. N.S. Wales acacias are showing signs of ambition.
Readings for the occultation of Jupiter.
Describing JH's observations and comparing notes.
Wind is likely to be higher in the evening. Would like JH's views on the effect that the motion of the center of the mural circle has on the readings of the microscopes. Wind was too high last night to observe Zeta Octantes.
Responds to TM's query in his 1835-1-17 about the effect that motion of the center of the mural circle would have on the microscopic readings.
Suggests a means of resolving TM's problem with the mural circle.
Additional approaches to resolving TM's mural circle problem [see JH's 1835-2-5].
Has just finished the observations of Mars and the circle is free from any particular use. Further comments on his query regarding the motion of the center of the mural circle. Would like JH's assistance on the examination. Has had some brass ingots stolen from the observatory.
Sends the projection of Monday's readings and one of those from the lever of contact for comparison; comments on this.
Has replied to Richard Sheepshanks in the Memoirs of the Astronomical Society. Is surprised how near he got to the general figure described by the Circle Centre. Comments on calculations he intends to carry out. Cannot say decidedly that Zeta Octantes is double; it is doubtful seen through the 8-ft. transit.
More on the mural circle [see JH's 1835-2-7].
Found two planetary nebulae not listed in any catalog; hopes to show them to JH tonight.
Apologizes for his erroneous reduction. Thanks TM for his list of 'Zenith points.'
Has been unable to locate the planetary nebulae; did JH give their places correctly, or is the instrument unequal to the task? Sends a comparison of John Pond's declinations and the Cape Zenith distances. Comments on the latitude of the Cape. The Hungerford got off yesterday.
Reports on location of a planetary nebula. Expresses thanks for book by [Robert] Woodhouse.
Some comments about constant error in TM's observations.
Much obliged for JH looking over the observations. Comments on these and the accuracy of the Cape circle and mural circle. Will send his observations on Crucis.
Encloses the Brisbane observations. Appears to be a discrepancy in some of the stars.
