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.
Summary of research on terrestrial magnetism in other countries. Will send paper on magnetic storms to JH.
Sends sample sheets of magnetic reductions from continual observations photographed at Kew. Explains reduction formulas. Will send to JH new paper by ES on lunar diurnal variation. Carlo Matteucci reports interest by new government in Naples in reviving meteorological observatory there.
Asks JH to comment on ES's paper, which will be read to R.S.L. on 10 Jan. Corrects errors in two earlier letters to JH. Will adopt 'Photograms' instead of 'Photographs.'
[Form Letter] GA's address, as Astronomer Royal, to Board of Visitors. Progress report on F. G. W. Struve's proposal for joint French-English-Belgian triangulation survey.
Sends 'something about the Moon.' It is all the printer has produced so far.
Comments on, and encloses, a letter from JH's son William James, who has accepted responsibility for trying to resolve a grave situation [in India].
Does not wish to forward some letters of AS's brother, Richard, as JH has made marginal notes he would not wish others to read.
Urges JH to attend the next meeting of the Board of Visitors of the Royal Observatory, especially as GA believes some of the members of the Board do not understand the scientific problem [?].
Circular letter advising of the availability of back copies of various Royal Observatory printed observations.
Comments on the publication of several volumes.
Dissatisfied with [F. W. A.] Angelander's nomenclature of variable stars; seeks JH's approval of NP's nomenclature for the new 'Hartwell Atlas of Variable Stars.'
Agrees with NP's proposed method of designating variable stars. Offers some suggestions from JH's own experience.
Thanks JH for supporting his proposed method of designating variable stars, adding that G. B. Airy, J. R. Hind, and W. H. Smyth also accept it. Hopes to succeed M. J. Johnson as director of Oxford's Radcliffe Observatory.
Has heard that JH's son [Alexander] is observing variable stars at Charles Pritchard's school. Gives latest data on these stars. Suggests other variables to observe. Has adopted JH's proposal of using Julian day numbers for dating variables in his catalogue of variables.
Thanks JH for 'testimonial' to the Radcliffe Observatory on his behalf, but the response is not encouraging. Describes the tribulations of his career in astronomy. Makes further suggestions regarding the variable stars being observed by JH's son [Alexander].
Regrets that JH's son Alexander is quitting astronomy. Asks JH to support his effort to obtain position at Madras Observatory. Announces first project would be survey of southern heavens in completion of [F. W. A.] Argelander's new atlas.
Supplies what is in effect a testimonial to NP's abilities for use in NP's quest to become director of the Madras Observatory.
Announces success in securing directorship of Madras Observatory, thanks to JH and G. B. Airy. Cannot now change the names for asteroids Hestia or Isis. Asks for suggestions on names in the case of future discoveries.
Congratulates NP on appointment to Madras Observatory. States that he will use both Isis and Hestia nomenclature without misgiving. Furnishes names from Greek mythology for NP to use for asteroid discoveries.
Describes, using a diagram, how the solar protuberances appeared to him as a color-blind person when he observed a solar eclipse.
