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.
The reductions are essentially complete; encourages JH in his part of the work and concludes 'It will be a noble work' [see JH's 1862-11-5].
Asks GA for a copy of G. F. J. A. Auwers's nebula catalogue [see GA's 1862-11-17], and a sample of the nebula listing for JH's catalogue.
Regarding financial affairs. Is having trouble with his eyes. Has done little of late.
Sends a copy of the first part of A. D'Orsan's new work on Our Satellite. Intends to bring it to the notice of the R.A.S. at their next meeting.
Thanks for letter. Further regarding Our Satellite by A. D'Orsan and its similarity to a work of Warren de La Rue.
Comments on the recent meeting at the R.A.S. when A. D'Orsan's book was shown.
Comments on some papers of JD relating to the theory of rain.
Is grateful for his comments on his paper. Will adapt them to his own hypothesis.
Little work remaining in calculations for JH's nebulae. Likes JH's plan to represent 'the quantification of different qualifications' by numbers. Hold payment until work is done. Astounding disturbances in 'magnetic curves' (1841-1857). GA now accepts usefulness of magnetic observatories.
Astronomische Nachrichten 1392 compares positions of forty nebulae by G. F. J. A. von Auwers, H. L. d'Arrest, and P. E. Laugier. Calculations for JH's [Catalogue of] Nebulae are complete and ready for inspection.
Compares positions for variable nebula in Taurus reported by several astronomers. Plans to incorporate JH's suggestion regarding Julian calendar into more convenient table of dates.
Best candidate for WL's assistant seems to be [Albert] Marth of Durham. Describes new planetary nebula.
Accounts for money spent in reducing JH's catalogue of nebulae. Encloses sample page from catalogue and Astronomische Nachrichten No. 1392 [see JH's 1862-11-18].
Please send receipt for £20.
Comments on HW's The Earth and Its Mechanism. HW erred by taking at face value François Arago's 'enormous blunder' of proving rotation from diurnal aberration.
Calls attention to a report of a lake in Central America that 'gives rise to two rivers.'
Regrets the delay in his reply, but JH's letter was misdirected. It appears that his own theories are neither original nor correct and thanks him for his opinions.
Recognizes the force of JH's arguments but wrote his paper not for a reputation in science but for protection of his character as a gentleman.
Sending the results of some recent balloon flights. Comments on these. Would be pleased to see Alexander Herschel when he is free.
