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.
JH's letter lays terrible responsibilities at his door. Should not neglect the offer. Regarding the Julian calendar.
Thanks for his pamphlet on 'Trade Unions and the Cost of Labour.' Comments on this.
Discusses her theory of aerolites and the zodiacal light. Used to visit his house at Slough.
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.
Thanks for his letter about her theory regarding aerolites. Has another query on this question.
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.'
Note to accompany forwarding of a letter; remarks on T. R. Robinson's upcoming cataract surgery.
Writes to compare notes on sunspot observations.
Has written to Kew Observatory to send on the photographs.
Is sending solar autographs. Notes that in groups of spots the larger precede the smaller spots. Can JH form any theories from this?
Detached postscript that discusses the margins of the two photographs, which seem to show that all planets are in the near hemisphere.
Would like him to accept the enclosed paper on the cause and effect of dew. Comments on various points.
The volumes of the Sinai photographs will be dispatched tomorrow. The cost of the survey has been covered by subscriptions and he will forward a statement of the account later.
Has no idea whether the sunspots appeared suddenly or gradually. The Kew people may be able to help in this matter. Comments on some more sunspots.
Sends two of his publications, one on terrestrial magnetism at Berlin. Comments on the results, and wonders if JH would enlist the help of the B.A.A.S. to finance further studies by H. J. R. Petersen.
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.
Sends map from his new atlas. Reports finding a region rich in bright stars in the northern hemisphere but distinct from the Milky Way. States that in a Royal Institution lecture, he will claim that telescopes cannot reach the limits of the sidereal system and that it is far more complex than traditionally assumed.
