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.
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.
Thanks for his help regarding his nephew. Hopes mild weather has not upset JH. Doubtless he has seen notes of the various observations of Saturn in R.A.S.M.N.
Will be happy to place his diagrams of the sun at JH's disposal should he wish to include them in the new edition of his book. Gives recent observations made by his Clarke object glass.
Would like his opinion on a divided glass, double image micrometer before he submits it to an optician. George Dollond has lent him some divided glasses of long focus. Would like to borrow G. B. Amici's micrometer if JH could spare it.
Is much obliged for the loan of G. B. Amici's micrometer. Comments on some of his readings with it. Is sorry to hear of the ill-health of Lady Herschel.
Is grateful for the gift of the instrument and hopes to put it to good use. Will report on it when he has mastered its use. Hopes the country air is improving JH's health.
Results of observations using the G. B. Amici micrometer.
Is grateful for the copy of his Essays. Query about measuring the focal length of a double object glass. Gives results of his recent observations. Hopes accounts of JH's son are good.
Discusses his telescopes and their dimensions. Wants to obtain an object glass of an 8-in. aperture.
