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.
Would support the application for a grant [see JH's 1870-5-12], but would like to see some changes in the way calculations are made.
Refers to several items of correspondence, and then comments on the calculation of Gaussian earth-constants to a higher power than has been done to date.
Assures RP that he is not upset at RP for publicly questioning some of JH's ideas. Continues discussion of point in perturbation theory for Uranus.
The Council of the R.A.S. would like JH's opinion on the accompanying paper and drawing by Francis Abbott, and whether it should appear in the R.A.S.M.N.
Admits JH is correct in suggested correction of RP's statement regarding perturbations of Uranus. Suggests that JH urge astronomers to observe the solar corona carefully.
Giving his opinion on a paper and drawing of [Francis] Abbott.
Further report on a paper and drawing of [Francis] Abbot [very similar to WH's 1870-5-18].
Expresses skepticism on the claims made by F. Abbott, observing from Tasmania, of the detection of changes in the Eta Argus nebula. Compares Abbott's drawings with drawings made by JH and and by JH's son John.
Will visit JH on 27 May.
About an application to the B.A.A.S. for a grant to fund the calculations related to reducing the magnetic observations of 1847-48.
Apologizes for delay in responding to JH. Wrote to JH yesterday about AM's plan to visit Collingwood.
Appreciates JH's opinion regarding variability of climate, although it disagrees with his own. His views are not provable and the question remains one of probability.
[Richard?] Proctor [?] agrees with JR's views on Cosmical Climates. Re-presents his theory because he feels he did not state it fairly in his earlier [1870-5-27] letter.
Sending letter from a firm of stockbrokers giving a reply to JH's query regarding the East India Dock shares.
Is grateful for his letter. Sends a report of the Geological Institute, which includes JH's notes on the founding of the Cambridge Analytical Society. Sends his own report on Homeric irons and on the R.S.L. catalogue of scientific papers. Austrian science was at a low ebb but is now improving.
Continues to explain matters in perturbation theory. Stresses need for careful observations in solar eclipses. Doubts the existence of the hypothetical intermercurial planet Vulcan.
Admits his misstatement in RP's Other Worlds than Ours concerning perturbation of outer planets. Shares JH's doubts about existence of Vulcan. Speculates on the extent of meteoric material in the solar system. Comments negatively on J. Norman Lockyer's views on meteors.
Regarding Alexander Herschel's paper on acoustical oscillations recently sent to G. A. Erman.
Thanks for work on diamagnetism and magne-crystallic action [Researches on Diamagnetism (1870)], which JH is excited to read. Mentions long-abandoned plans for magnetization experiments. Envies those who can see JT's 'magic' experiments at Royal Institution.
Gratified by JH's 'sympathy and approbation,' and that JH's writing and spirit remain 'firm' and 'fresh.'
