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.
Discusses the purchase price of Mme. Witte's lunar model.
Asks JH's advice on the purchase of the lunar model. Anxious to see JH's new method of calculating double star orbits.
Suggests trustees of British Museum make an offer for Mme. Witte's lunar model. Cape Results at press. Observed double comet.
Double star orbits not ready; R.A.S. waiting for JH's new calculating method. Reads accounts of Biela's Comet. Describes Edinburgh Observatory in detail.
Believes Beta Ursae Minoris to be a slow variable star. Remarks on diminution of the star's brightness between 1840 and 1841.
Receives report on poor state of Paramatta Observatory. Encloses letter from Thomas Brisbane, who believes James Dunlop should be removed from his post of authority there.
Suggests method to check the effectiveness of James Dunlop's work at Paramatta Obsrvatory..
Sends copy of James Graham's letter concerning transfer of Paramatta Observatory to government authority. Thanks JH for advice on the matter. Discusses methods of magnitude estimation.
Sends copy of J. R. Hind's observations of Gamma Virginis; believes they are 'too slow.' Also sends report of the Charter Committee of the R.S.L. Believes R.S.L. not selective enough. Has difficultly using JH's method of magnitude determination.
Encloses copy of 29 July 1846 letter from G. B. Airy, who refuses to act on any further recommendations from Board of Visitors so long as James South is member of Board. Insinuations by South in R. H. Inglis's motion before House of Commons are deemed malevolent by Airy, who no longer considers South competent to guide scientific inquiry.
Received WS's note about G. B. Airy's action regarding new warrant for Board of Visitors. Feels that Airy's cooperation is necessary in light of anomalous position of one board member. Recommends referring matter to Admiralty.
Discusses magnitude determination. Refers to incident in which one of WS's sons will be removed from his position but not given poor references. W. S. Jacob sends double star measurements.
Discusses controversy over the discovery of Neptune. Astronomical committee of R.S.L. advised to award U. J. J. Leverrier the Copley Medal.
Lunar model will be placed in Somerset House.
Believes council should decide the handling of the medal over the discovery of Neptune. Thinks that if J. C. Adams receives a medal, U. J. J. Leverrier should receive 'the more prominent distinction.'
Discusses Neptune discovery controversy; believes both scientists should receive medals.
Plans to write John Russell in an effort to secure a pension for Thomas Maclear; asks for R.A.S. and WS's support. Asks WS to obtain some facts relevant to pension request.
Asks WS if possible to enclose a note by Francis Beaufort to John Russell concerning request for pension for Thomas Maclear. Lays aside double star observations; continues work on orbit equation.
Asks WS to take the chair at the next meeting of the R.A.S [probably concerning the Adams-Leverrier dispute].
Proposal of giving medals to both J. C. Adams and U. J. J. Leverrier by William Whewell turned down by R.A.S.
