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.
Of JG's travels and the people he meets [letter completed 1828-5-17 in Nantes].
Believes it was not our Captain Foster to whom the advertisement alluded. Singular way in which Mr. Barrowcliff discharges his trust.
Is sending copies of a memoir on the triangulation of Savoy, prepared by GP and [Mr. ?] Carlini. Is including copies for other scientists and organizations.
Has not heard from [University of Virginia]. Position of lecturer in mathematics and natural philosophy has opened at Dollar Institution in Edinburgh. WR asks for recommendation for the position from JH.
Has not heard from America. Discusses paper on electric conduction. Wishes to move further south. Thanks JH for securing WR's election to R.S.L.
Accepts JH's extension of Class I double stars. Comments on comparison of these and suggests comparison of respective scales might be mutually useful. Includes continuation of work on micrometer measurements of Saturn. Notices strange eccentricity of Saturn's rings. Is considering comparing his degree-measurements with Finland and Lapland.
Regarding Joseph Clement and the work on his machine. Account of his recent excursions.
Regarding the meeting, and the papers read last Friday. Invitation to dine with him and Sir Thomas Brisbane. Regarding Brisbane's observations. Various Astronomical Society affairs.
T. M. Brisbane is in town. Can JH meet him? JH's computations of definite integrals are simpler, more direct than P. S. Laplace's and more conclusive than Leonhard Euler's. Comments on W. H. F. Talbot's letters demonstrating Josef Fraunhofer's theorem.
Abandons TY's argument on Mr. Roberts's object glass. Asks JH's help in understanding A. J. Fresnel's calculations of diffraction and Josef Fraunhofer's discontinuous functions.
Board of Longitude would approve providing Lieutenant Forbes with apparatus JH suggested. Inappropriate for any member to address Admiralty separately. Payment of expenses to committee members.
Is grateful for JH's invitation to her brother to visit him. Would like advice on a suitable mathematics tutor for her brother.
Is about to leave for England with Alphonse de Candolle. Gives news of his latest astronomical observations. Lists people he has met or hopes to meet.
