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.
Thanks WH for materials WH sent, including information about scientific activity in Vienna and papers on meteorites. Recounts some of the history of the Analytical Society. Discusses meteorites and also Homeric references to iron.
Thanks for his pamphlet on 'Trade Unions and the Cost of Labour.' Comments on this.
Examples from Iliad and other sources to show that military offensive tactic called 'Vertical Fire' did not originate with [L. N. M.] Carnot, as Mr. Mallet claimed in recent issue of Budget.
No permanent optical solution to DS's double vision. Remarks on description by DS's son of cavalry duty in Ireland and Canada.
Inquires about other sunspot observations made by JH.
Asks whether WS has photographs of the sun for 21 and 22 April. Notes how curious sunspot activity has been. Doubts that such is reconcilable with the notion of 'meteoric in-falls.'
Writes to compare notes on sunspot observations.
Comments on the effect of great temperature variations on the speculum of a telescope.
ES has been forwarded letter explaining why 'great telescope' at Melbourne will not work and suggesting construction corrections, on which JH, who believes such 'a priori condemnation' unjustified, comments herein.
Is returning March heliographs. Discusses the appearance of the spots. Has not received the April heliographs.
Wants to compare Mr. Titterton's photographs of the spot groups to [Warren] de La Rue's. Has tried to determine if some localities regularly have spots.
Thanks for the photographs WD sent for the dates requested in JH's 1870-4-23.
Thanks for sending G. A. Erman's two papers on terrestrial magnetism and letter to JH. Will forward these to G. G. Stokes with recommendation that B.A.A.S. continue funding for reduction work of H. J. R. Petersen. Awaits AM's visit to Collingwood.
Forwards letter from G. A. Erman of Berlin requesting that B.A.A.S. fund [H. J. R.] Petersen's study of terrestrial magnetism.
Writes to support grant request from Georg Erman of Berlin to allow Erman to do calculations on magnetism observations from circumnavigation of world.
Thanks RP for sending RP's Other Worlds than Ours and supplies comments, some favorable, on numerous claims made therein, e.g., on RP's theory that Jupiter and Saturn are hot and to some degree luminous.
About a grant to support [H. J. R.] Petersen while he carries out the reduction of terrestrial magnetic observations.
The research shows no particularly 'maculiferous' area on the sun, but WS may, as WS requested, present 'data' to the R.A.S. Has noticed two new spots on helioautographs on 20 and 27 April.
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.
Giving his opinion on a paper and drawing of [Francis] Abbott.
