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 current debate over placement of telescope in India. Discusses various possibilities for telescope.
Sends copy of B.A.A.S. resolution regarding telescope in India. ES and R.S.L. colleagues agree to take no further steps in matter.
Glad to have met JH's son [John]. Describes benefits of [R.S.L.] meetings for cultivation of science.
Wants information regarding undulatory theory of light controversy and the role of Lord [Henry ] Brougham for his obituary. Congratulates good performance of JH's son [John?] in India.
Discusses [William] Sharpey's view of JH's opinion of [Henry] Brougham's optical writings. Asks for JH's advice on presenting meteorological observations. On observations of an eclipse.
Discusses papers concerning light on [William] Sharpey's list. Discusses, very critically, Henry Brougham's optical researches.
Asks JH to sign [C. P. B.] Walker's certificate for the R.S.L.
A metallic thermometer will be constructed at Kew Observatory to test JH's proposal. Experiments on Index of Friction of gases to be resumed at Kew.
Asks JH to send an actinometer to Kew. It will be forwarded with other meteorological instruments to the Paris Exhibition.
Describes pendulum design. Believes [Henry] Kater's is the best. Regrets Russians want to make own pendulum. Discusses nominees, including [G. P.] Bond, for R.S.L. foreign membership.
Thanks JH for information regarding Henry Brougham [see ES's 1868-9-29 & 1868-10-8]. Also for comment on polarization of aurora. Encloses Captain [John?] Hay's letter, but not plate.
JH will be pleased with Mr. de Souza's and [Charles] Smallwood's letters. American and Havana instruments were dispatched. [Hermann] Schlagintweit has made interesting magnetic survey of India.
Advises on the construction of the Melbourne reflecting telescope. Thinks [W. P.] Wilson should come to watch construction.
Encloses proposed resolution to controversy over whether to build railway tunnel under park. Will be unable to attend meeting because of chronic bronchitis.
JH's catalog of nebulae, reduced to 1880 as originally planned, is nearly complete and consumed all of £20 granted by R.S.L. Seeks £16 more to expand catalog and reduce data to 1860, as recommended by G. B. Airy.
Had hoped to attend ES's soiree, but has influenza. Praises ES's report on Mr. McClintock's magnetic observations at Port Barrow.
Gives reasons for and discusses technicalities of supporting pendulum experiments at astronomical and geodesical stations in Indian trigonometrical survey.
Discusses negotiations between government and R.S.L. regarding Meteorological Departments of Board of Trade.
Maintains that a first class refractor is not needed at Masouri in India [see ES's 1866-9-4]. No special characteristics there justify the great expense of such a project.
Forwarded JH's request for additional £16 [to publish map of nebulae] to [R.S.L. secretaries] William Sharpey and G. G. Stokes. Expects approval.
