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.
Provides information [see GA's 1840-8-13] based on equipping the Breslau Observatory; also comments on lawyers, meteor showers, and photography.
Has passed on GA's note to Edward Sabine; cannot write more because his hand shakes too much, having just made a snow-man for the children.
Sends a letter from Humphrey Lloyd for GA's comments.
Thanks GA for his comments [see GA's 1842-1-18]; hopes that GA would be willing to have such statements, and other similar statements, made public.
Asks GA's opinion as to whether Ordinance observatories should make their magnetic observations on a 3-minute or 5-minute system.
Is organizing a committee to revise the instructions for observers at magnetic observatories; GA is on it.
Suggests to GA that his observations [see GA's 1847-11-1] might rather support than destroy the theory of the thermo-electric origin of terrestrial magnetism.
Passes along a report that someone took a 4-foot telescope to the top of Snowdon [mountain], from where he could see the eight satellites of Saturn and the rings of Neptune.
Expresses unease about P. S. Laplace's formulation of the barometric determination of height; in a postscript comments that Michael Faraday's lecture on conservation of force is a 'strange production.'
Has received GA's paper on spectral lines and is amazed that it is possible to see a spectrum in the light from faint nebulae.
About observing a grain-shaped spot on the sun; greetings to Friedrich Winnecke.
Sends GA [see GA's 1863-11-21] JH's copy of the Melbourne telescope correspondence and reports; needs information from GA and Edwin Dunkin about the sun's motion, although JH questions some of Dunkin's work.
Thanks GA for the papers sent; asks GA to review enclosed note on solar motion [see JH's 1863-11-22].
Has received the papers [see GA's 1851-10-7]; Sydney University seeks assistance in finding professors. What should the response be?
An invitation sent out by JH to invite all search committee members [Sydney Trust] to JH's house [see GA's 1851-10-16].
Note with copies of an advertising circular about the Sydney University professorships [see JH's 1851-10-16].
Information about some candidates for Sydney University professorships [see JH's 1851-10-29].
Comments on several nebulae, and on GA's receiving an honorary degree [from Cambridge University].
Partly identical to JH's 1851-11-16, but with different information about some candidates.
A note about the receipt of papers from Richard Sheepshanks.
