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.
Asserts that a process for obtaining 'Turnbull's blue' recently published in PN was discovered and published in 1842 by JH. Adds a second case in which JH anticipated another author's result.
Responds to GS's letters of 1864-2-4 about procedures for printing JH's 'Catalogue of Nebulae' and receipt of William Herschel's manuscripts .
Further about nebulae catalogue [see JH's 1864-2-5].
JH declines to negotiate further about FT's continuing occupancy of Herschel House.
Comments and will consider writing on article subjects proposed by Dr. [Norman?] McLeod. Requests Hebrew version of Genesis, chapter 1, with pronunciation and translation guides.
As JH has made minor changes in many calculated results, the proof sheets cannot be easily compared with the calculation sheets [see GA's 1864-2-6].
Is trying to discover the train connections that will allow JH to come to a meeting of the Standards Committee without coming to London overnight. 'Catalogue of Nebulae' is now in proof state [see GA's 1863-10-9] and needs to be checked.
Is now too ill to come to the meeting of the Standards Committee; replies to GA's queries about how to clean up the pound [see GA's 1864-2-8].
Charles Pritchard was wrong in ascribing priority for diagonal reflecting telescope in Pritchard's address to R.A.S. As early as 1825, JH was first to use diagonal reflector. Describes its construction.
Did not insinuate that RH plagiarized JH's idea of 'diagonal reflector,' but feels justified in defending JH's claim to being first to apply it.
Responds to WW's comments on parts of JH's translation of Homer's Iliad. Is sending his rendering of Book V. Has been ill.
