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 magnetic observations from Toronto and Hobarton from the 1840s. Attempting to determine when range of variation was greatest.
Stopped compilation of comet orbits because it had already been done. Would provide money from donation fund to distribute copies of this information.
Hopes JH will present application of Kew Committee for financial aid at next council meeting. Includes suggestions for maximizing credibility of application.
Discusses auroral observation. Will reply to [John] Lefroy's letter soon. Wants grant proposals sent to outlying R.S.L. members for comments. Cannot attend Kew Committee meeting.
Recommends use of photography to prepare records of sunspot activity. Makes suggestions on how this could be done most effectively.
Glad JH is recovering and free from official duties [at the Mint]. Discusses his upcoming papers regarding magnetism.
Comments on a proposed grant to publish T. R. Robinson's Armagh observations.
Returns polar maps. Advises on methods of map projection, favoring polar projection. Working on new maps.
Writing article [for Encyclopaedia Britannica] on meteorology. Asks questions regarding work of [H. W.] Dove and [Thomas?] Taylor regarding cyclone and storm theory. Discusses barometric fluctuation.
Discusses [H. W.] Dove's works regarding rotating storms. New information from Russian observatories gives a more complete understanding of the phenomenon. Has not seen Keith Johnson's new edition of Physical Atlas.
Thanks ES for his paper. Sun spot activity should increase in 1857. Discusses his own earlier ideas concerning relationship between sun spots and Aurora Borealis.
Glad to know which of ES's papers JH has. Sends another along with maps from [Keith] Johnson's Physical Atlas. Discusses JH's ideas regarding relationship between solar spots and magnetic disturbances.
Mentions [P.] Plantamour's memoir on barometer and a criticism by Mr. Dilams[?]. Comprehending why variations of magnetic disturbances correspond in period with terrestrial year is difficult.
Discusses advantages of different magnetic charts. Grateful for [P.] Plantamour's observations. Satisfied with [J. R.] Wolf's period of 11.11 years for solar spots.
Heard ES recommended JH write an article for Edinburgh Review on terrestrial magnetism. Asks what he should read to write this article. Photographs ES sent of sun not promising.
Asks JH to read ES's publications for the R.S.L. proceedings concerning colonial magnetic observations. Wishes JH could see R.S.L.'s recent accomplishments in magnetism.
Willing to write article if Quarterly [Review] will publish it, if he may take his time writing, and if ES will provide aid regarding meteorology and magnetism.
Glad JH is reviewing advancement of science by R.S.L. members. Disappointed that little was accomplished in certain areas where more was expected.
Thanks ES for receipt of information about magnetic curves and the work of [A. D.] Bache. JH is glad to hear ES is back to active work again, but JH says he is too ill to go to the B.A.A.S. meeting [in Aberdeen].
Sends section X and earlier paper on Kew and Nertschinsk disturbances, which supply key to theory of magnetic disturbances.
