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.
Will be out of town for next [R.S.L.?] council meeting. Comments on glass subcommittee report.
Thanks for the works. How can he send some for the R.S.L. and Astronomical Society?
It appears that J. T. Cooper would be willing to work in the performing of glass experiments. If this seems acceptable, then a meeting of the glass committee should be called.
Is sailing for Buenos Ayres in a few days' time. Would like to thank JH for his kindness; would also like to see him, if convenient, before he departs.
Introducing his friend Mr. De Lavigne, who is visiting England. Mentioned him in his memoir on the Measure of the Arc.... Gives news of his own astronomical work. Edward Sabine arrives at the end of the month. Has obtained remarkable results with his two pendulums.
Has received the actinometer safely by the hand of Mr. De Lavigne, also the instructions. Hopes to use it in the Alps, and will send some observations. De Lavigne was enchanted with England.
Has just returned from the Alps, where he worked on the glacier at Chamouny and in the St. Bernard. Comments on his work and on the work of the actinometer. Regrets to hear of the death of Mrs. Babbage.
Outlines the difficulties he has had to return JH's actinometer. Gives details of his observations in the Alps. Comments on the chronometer used.
Sending observations of his barometrical observations made during the summer at Chamouny. Comments on them and the work of [Alfred?] Gautier.
Sends copies of a paper to JH and D. F. J. Arago on a chemical experiment being conducted at the Institute of France. Asks JH to present it to the R.S.L.
Informs HK that JH intends to resign as secretary of the R.S.L.
Discusses comet observations, together with variations from different observers. HO offers some historical fragments about the planet Venus, and about the Lilienthal telescope.
Comments on the observations JH has made with his 20-foot telescope, especially nebulae. HO provides some of his own observational data of Comet Encke.
Is afraid JH will decline the invitation to be a candidate for the Lucasian professorship, so it is assumed Charles Babbage will be elected.
Urges JH to miss the next R.S.L. Council meeting, as many friends have been to see Charles Babbage, and are proposing to make the meeting difficult. GB suggests that JH remain at Slough because of his mother's illness.
Informs DG that JH is resigning as secretary of R.S.L. [at the anniversary date?] and expresses great regret that some regard the position of secretary not as an elected position, but in the patronage of the President.
Thanks JH for his assistance with edition of William Herschel's writings [see JH's 1824-6-30]. JP indicates volume two is ready for submission to printer.
Needs money to employ men working on Charles Babbage's calculating machine.
Dionysius Lardner is candidate for Dublin Observatory. Please send Edward Sabine's paper on longitude.
Comments on [Pierrre] Guinand's glass making process. Believes the glass made Guinand's way will be too expensive [see JH's 1827-10-20].
