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.
Sending the results of his calculations of the parallaxes of the southern stars. Has recommended these stars to Thomas Maclear to observe.
Was hoping to send him some positive paper, but has been unable to prepare this due to a medical problem. Did make a sheet or two today. Returns some of the specimens JH sent him but would like to keep those made by JH himself.
It is a long time since he thanked him for the assistance in becoming a member of the R.S.L. and the R.A.S. Doubtless his work at the Cape was a great success. Hoped to visit England again but seems improbable now. Sends J. F. Encke's memoir for the R.S.L., R.A.S. and JH. Is very interested in his memoir on the variable light of Orionis. C. F. Gauss continues his magnetism.
Asks whether JH will be prepared to give the committee report on systems of simultaneous magnetical and meteorological observations at the B.A.A.S. meeting on 23 June.
Asks whether JH will be prepared to present the committee report on N. L. Lacaille's stars at the B.A.A.S. meeting on 23 June.
GP's views on continuation of magnetic observatories in colonies.
Has been trying to make other metallo-cyanides at JH's request, but without success.
Sends JH the current position of Gamma Virginis.
Suggests new method of gold plating the telescopic mirrors to prevent oxidation. Mentions having tried to galvanize the mirrors with 'Galvana plastik.'
Thanks for assistance in preparing trip. JH's daughters will probably not stay in Brussels long. Mentions his first engraving for Cape observations of nebulae is to be engraved this very day. Three quarters of his reductions of the southern sweeps are completed.
Thanks JH for interest taken in periodic phenomena. Discusses train information and preferred hotel accommodations for JH's visit.
Proposes meeting times in town. Suggests that JF observe the upcoming total eclipse astronomically. Agrees with JF's seemingly 'cold &c' circular on scientific partnerships, while regretting that it needed to be written.
About the length of a Board of Visitors' meeting, and about arrangements afterward.
Sets up approximate meeting time, depending on his family's timely departure to Antwerp, with JF at the R.S.L. apartments.
Some information about Charles Piazzi Smyth. JH needs information about some of RH's photographic paper, which JH has tried but without success.
Thanks WS for C. P. Smyth drawings of Cape monument and Gamma Virginis observations. Notes J. H. Mädler's work on double stars and the doubt that they obey the inverse square law. Discusses use of photography in astronomy.
Will JH be prepared to present report on 'Nomenclature of Stars' at Manchester meeting in June?
Would like to see him for a few minutes to discuss a paper he is preparing for the R.S.L. on actinometer observations.
No meeting of the R.S.L. on the 19th but could arrange to see him before dinner. Hopes to spend the summer amongst the glaciers.
