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 regulations of bequest, which will benefit chemistry and physics. Discusses relationship between solar spot period and magnetic disturbances. Wants JH's comments on paper regarding this topic.
Believes similarity of period of solar spots and that of terrestrial magnetic variation is more than coincidental.
Discusses magnetic observations from Toronto and Hobarton from the 1840s. Attempting to determine when range of variation was greatest.
Glad JH is recovering and free from official duties [at the Mint]. Discusses his upcoming papers regarding magnetism.
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.
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.
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.
Glad JH is reviewing advancement of science by R.S.L. members. Disappointed that little was accomplished in certain areas where more was expected.
Discusses ellipticity and results of [G. B.] Airy and [F. W.] Bessel. Also, [Alexander von] Humboldt's magnetic results.
Wife not well enough to visit Collingwood. ES may come next week. University of Kasan Observatory may assist British endeavors. Mr. Bolyani is very capable.
Would be glad to accompany JH to Kew to see instruments.
Will travel to Kew Tuesday. Encloses answer to Duke of Newcastle regarding proposal for colonies. Welcomes any comments from JH.
Encloses letter from Colonial Office to R.S.L., which was referred to ES because [B. C.] Brodie was out of town. Brodie hopes to see JH when JH comes to London.
Discusses [Angelo] Secchi's letter. Can supply the Jesuits in Cuba with magnetic apparatus they need. Discusses Secchi's views on cause of earthquakes and volcanic eruptions.
Must postpone meeting at Kew Observatory because of a severe cold. Asks JH to choose a later date.
Sends section X and earlier paper on Kew and Nertschinsk disturbances, which supply key to theory of magnetic disturbances.
Returns polar maps. Advises on methods of map projection, favoring polar projection. Working on new maps.
Glad to have seen Lady Herschel and children. Is recovering slowly. Thanks JH for interest in [Francis] Ronalds's work. Discusses paper ES has submitted for R.S.P.T.
Hopes JH will present application of Kew Committee for financial aid at next council meeting. Includes suggestions for maximizing credibility of application.
