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.
Giving the plan of the Observatory.
Seems clear that JH's 'falling star' [see JH's 1845-4-29] was the same one reported by a correspondent of GA's as having been seen in Nottingham; in a postscript JH is not so sure.
Accepts GP's invitation to visit him at Ely Cathedral after the B.A.A.S. meeting at Cambridge. Asks advice on whether it would be proper for JH to read his address at the meeting.
Alerts WW, who was coming to visit the Herschels, that scarlet fever has arrived at JH's household. Comments onWW's writings about glacial theory.
Invites Whewells to visit for a luncheon. Thanks WW for and comments on WW's publications on glaciers. Comments on Richard Jones.
On the subsuming of one scientific society by another; comments favorably on the Memoirs of the Cambridge University Philosophical Society and asks AD to help fill in JH's missing items.
Remarks on observation of new comet. Discord in R.A.S. follows Francis Baily's death. C. P. Smyth will leave Cape after being appointed Astronomer Royal to Scotland. Glass for Cape equatorial tested. JH has no success appealing for continuation of Colonial Survey. Southern constellation reform compromised.
Describes testing William Simms's object glass and then gives details of the equatorial mounting GA used; offers to send carpenter to JH to construct mounting so JH can test object glass [diagram].
Critiques JD's paper on plant chemistry, contrasting 'luminous, colorific, calorific, & chemical or photographic' rays. Physics of light. [Letter continues two months later.] JH is done with photography. Has no desire to claim priorities in that field. Entrusts future to JD and others.
Note sent with package from [J. F.] Encke of Berlin.
Comments about engaging a gardener, concerns about Peter Stewart, and waiting for council and committee meetings [of the R.S.L.?]. The Physical Committee meeting was deferred because of a transit of Mercury.
Doubtful over WS's angle for Gamma Virginis; urges precision in measurement. Hopes to obtain moon map from R.A.S. during next visit to London. Unable to solve Aristarchus puzzle.
Sends Gamma Virginis data. Will report Aurora Borealis observations to R.A.S.
Announces change in meeting time of Council on 14 May.
Announces 15 May meeting of Physics Committee.
Several items of R.S.L. business.
Hears from the Dean of Ely that JH is busy writing his B.A.A.S. oration. Sent a new volume yesterday. Wished JH had been at RM's soiree on Wednesday.
Encloses transcript of letter dealing with object-glasses. Has given notice that he has withdrawn from the Physical Committee of the R.S.L.
Provides detailed information about JH's responsibilities as President of the B.A.A.S.
Gives reasons why telescope for Cape Observatory should be as perfect as possible. Doubts that its 'finder' is adequate.
