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.
Observed a bright nebulous mass this evening. Gives readings for it. The comet is proceeding North. Has notified the Times.
If not too busy JH would have doubtless seen the recent comet on several evenings. Gives latest observations of Saturn and its satellites.
Sending paper by Andrew Ross, who would be glad of any comments. [William] Simms informs him that he has improved his 8" object glasses. Gives recent observations for Enceladus.
Measurements and diagrams of WD's 8.5-foot telescope, dome, and other structures at Camden Lodge [to be duplicated for shipment to Cape of Good Hope observatory]. Laments deaths of Julia Cornwallis and J. L. Felix Mendelssohn-Bartholdy.
Will certainly help him regarding the Cape dome. Gives details of his mounting. Sends a copy of his observations.
Has repaired the damage to his equatorial. Observed another of Wilhelm Struve's double stars last evening. Compares some of their star readings.
Should Mr. Morris, carpenter at Cranbrook, include canvas for covering dome, or will that be available at Cape Town? Improvements in WD's dome should be incorporated into Cape dome. Apologizes for WD's carelessness in managing telescope when JH visited.
Mr. Morris, the Cranbrook carpenter, has the plan and specification ready. Would JH like to see it before sending it to the Admiralty, presumably through Francis Beaufort?
Has found that Orionus is a double star. Compares William Lassell's and Wilhelm Struve's observations of various stars.
Admiralty have applied to Mr. Morris for the drawing of the stone pillar for the Cape equatorial by Georg Merz. Suggests that the type in use at Pulkowa be used. Weather prevented outing to Bodiam.
Returning JH's proof sheet with errors noted in pencil. Gives some of his recent observations on the satellites of Saturn.
Has experienced bad weather since the discovery of Saturn's 8th satellite. William Lassell proposes to call it Hyperion. Wishes Starfield Observatory was situated in a clearer atmosphere.
Recently observed Hyperion very faintly. Gives observation and drawings. The recent bad weather has prevented important observations.
Was grateful for C. R. Darwin's note. Glad to hear of the improved health of Sir J. Dundas. Gives recent observations of Alpha Virginis.
Sending a copy of the Torquay directory where Edward Vivian's comparison of thermometer readings are given. The climate of Torquay does not suit them; Mrs. Dawes is going north for a few weeks. Would like a comparison of the state of the weather for various parts of the country.
Regarding a certain Mr. Ray who applied for the position at Ormskirk. Is thinking about the removal of his observatory. His illness has upset his plans.
Concerning his recent visit to Starfield and the observations made by William Lassell with his 20 foot. Regarding the rings of Saturn. Has not heard of the Craig telescope.
Observed increased breadth of Saturn's ring on 25 and 29 Nov. 1850, confirmed by William Lassell on 3 Dec. Independent discovery of inner ring at Harvard University on 15 Nov. was announced in the Times on 3 Dec. Sent WD's notes to R.A.S. to establish independent discovery, but R.A.S.M.N. reported this erroneously.
Wishes WD had heeded JH's advice [in JH's 1851-1-18] regarding report of WD's discovery to R.A.S. Description of Saturn's inner ring.
Suggesting someone suitable as a Greek scholar. News of his relations. Is pleased she likes his description of the solar eclipse. Regarding the priority of the discovery of the faint rings of Saturn.
