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.
Sending a copy of the English Universities. Has quoted JH in the third volume. Hopes that university reform will be a popular topic.
Agrees with JH opinions of Gamma Virginis orbit. Sends JH a drawing by C. P. Smyth of Halley's Comet.
Has received the maps. Gives F. W. Bessel's views on the re-arrangement of the constellations which has been proposed. Comments on FB's memorandum.
Enclosing the specimens of photographs by different methods; comments on the methods used. Encloses a paper by Were Fox.
Sends calculations of Gamma Virginis and determines its eccentricity. Believes the orbit is highly elongated, like that of a comet.
Should JH be attending the B.A.A.S. meeting at Cork, hopes he will visit WP and spend a few days with him. Gives news of the progress of his great telescope.
Pleased with JH's Gamma Virginis results. Mr. Visconti made head of Military Geographical Institute at Naples.
Provides JH with the measurements from a series of observations of Gamma Virginis.
Had to leave Calcutta owing to his health and was entrusted with a packet for JH from a Mr. McClelland, and has only now succeeded in tracking down JH's new address. Will remain in England for a few years. Hopes that JH's Cape labors are progressing.
Will send JH's report to JH in August. J. C. Ross will not be at Cork meeting, but JH may announce there that first year of Ross's observations at sea will appear in R.S.P.T.
Is much obliged for letter and pretty specimen of English hexameters. Is sad that there has been no success with the classical hexameter in our language. Comments on its use.
If not already invited, he would be very welcome to be their guest at Bristol when the new iron screw ship is named by the Prince Consort. Outlines method of reaching Bristol.
The committee report on simultaneous magnetical and meteorological observations will be read at the B.A.A.S. meeting in Cork on 17 Aug.
Declines WP's invitation to attend Cork B.A.A.S. meeting and afterwards to visit WP and to see his reflecting telescopes. Informs WP that [C. A. von] Steinheil had written JH about a process of 'Electro-gilding' mirrors for telescopes.
Comments on calculation of orbit of Gamma Virginis; requests any observations EC has of that star.
Finds GA's measurements of Gamma Virginis far away from JH's own, and instructs GA in the best way to measure double star positions.
Devises and suggests mode of micrometric measurement of angles.
Refers to a variety of salts and their reaction to light in the production of photographs. JH hopes that [?] still intends to publish his work in this area.
Was gratified to receive JH's letter and intends to avail himself of the invitation to visit Hawkhurst. Will be visiting General [Bell]. Gives observations of the comet.
Regarding the measurement of angles. Observations on a problem set by JH.
