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.
Thanks JH for reply to letter questioning color experiment in JH's Familiar Lectures. Will conduct the experiment that JH suggests in the book.
Discusses an experiment, described by JH in JH's Familiar Lectures, involving applying colors to paper. FP finds that his results differ from JH's.
Sends him a vocabulary of Aboriginal dialects and University calendar. The response to his questionnaire has been very disappointing.
Comments on observations of meteors, comets, and the transit of Mercury.
JT's paper on polarization of sky light suggests that neutral points are functions of cloud density. This verifies JH's earlier explanation of blue sky color. Incomplete polarization. Cause of blue color in water. Corrects note on W. A. Miller's observations of rainbows.
Has received HT's pamphlet on crime and its prevention and punishment. Praises it and questions some particulars.
There having been reports of changes in the nebula around Eta Argus, JH sends the R.A.S. a letter from JH's son John [see JH's son's 1868-11-23] reporting his observations of that object. JH adds his comments.
