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.
JH has arranged for U. J. J. Leverrier, J. C. Adams, and Wilhelm Struve to visit JH together at Collingwood. JH is writing to invite JL to join them.
Promises to become more knowledgeable about [heat?] theory in order to be able to discuss it with JL. Cautions that the subject is an intricate one.
Mostly news of JH's family; JH inquires as to the state of health of JL's mother.
JH expresses some concern about the accuracy of a wet bulb thermometer, as he is not clear about the nature of the experimental base for its use.
Thanks for 'small, but intense' volume sent.
Is displeased by R.S.L. Council's seemingly rash resolution with regard to idea of permanent magnetic observatory.
Council passed 'with great unanimity' resolutions regarding permanent magnetic observatory to be established in London.
Thanks for letting JH know about honor accorded at 'the Anniversary' [Meeting]. Offers condolences on JL's 'late severe loss.'
Advice as to best way to present JL's method of calculating the orbits of comets to R.A.S. If JL desires R.A.S. to undertake calculations, might be some difficulty.
In light of minutes of R.S.L. Council meeting, outlines vision of permanent national physical observatory and, more importantly, an experimental institute or college. Hopes Edward Sabine will be interested.
Further remarks on council meeting about permanent magnetic observatory and G. B. Airy's answer [to invitation to head it?]. Awaits communication from William Lamb (Lord Melbourne).
Has talked to William Lamb (Lord Melbourne) about permanent magnetic and meteorological observatory. Was received 'as well as we could have anticipated,' but without definite answer. Thinks head for observatory should be appointed and give lectures.
Comments on several different reports; also on some experiments that lead JH to think much of the radiant energy of the Sun is absorbed in the atmosphere.
On the 'misfortunes & mishaps' of the Aden magnetic observatory and on the proper care of magnetical instruments.
Asks whether JL wishes to present method [see JH's 1847-12-4] at next R.A.S. meeting.
