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.
Received notes on omission of passage [1844-9-26] in good time. Asks JH to return proof of report. Regaining strength before going back to study Toronto volume.
Edinburgh [Review] named someone else as the person who found the true correction of the rate of pendulums on account of the atmospheric medium. ES actually discovered the correction first. Discusses [James] Ross's intensity ovals.
Sending proof copies of the report on the Toronto meteorological observations. Asks JH to make suggestions for corrections and improvements.
Obliged for JH's comments regarding pendulum apparatus. Discusses the article that wrongly attributes ES's discovery to [F. W.] Bessel and [Francis] Baily.
Sends actinometer observations of 1841 and 1842, which he will publish. Asks JH to look them over and make comments.
Discusses ES's experiments with convertible and travelling pendulums. Asks how 'für vaterländische Cultur' is to be translated for the list of societies.
Pleased that JH agrees on removal of tail pieces and moveable weights from pendulums. Discusses pendulum experiments in air and vacuums.
Discusses the best pendulum models inside and outside a vacuum apparatus. ES will be given credit for improving the manipulation of pendulums. Makes several other comments regarding pendulums.
Will attend to JH's wishes regarding the correspondence. Discusses the buoyancy correction for particular types of pendulums. Asks if JH has received the magnetic results from Geneva.
Sends 30 copies of JH's letters by coach. Will charge to the B.A.A.S. account.
Discusses prior meeting of B.A.A.S. to determine if [Cambridge] University would receive it. Says meeting went well. Asks if JH will agree to chair the B.A.A.S. meeting.

Introduces [Wilhelm] Döllen, who wishes to meet JH. WS recommends Munich glass for the Cape telescope.
Has worked hard to augment number of stations for horary observations. Now close to 80. Asks JH's advice whether the R.S.L. or B.A.A.S. would print his observations.
Thanks for letter regarding equinoxes and solstices. Intends to work on physical phenomena of globe. Resumes meteorological observations. Awaits Cape Results.
