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.
Asks JH questions about a paper on the dispersion of light from beyond the visible violet end of spectrum.
Has been studying the spectral lines of 'invisible' rays.
Asks about problems in GS's paper that JH is reviewing. Remarks on spectral lines paper presented by Antoine Becquerel to Academie des sciences.
Surprised by length of spectrum produced by the combustion of metals, using electricity.
Writes to clarify his understanding of the word 'fluorescence.' Asks JH to review a paper on color-blindness.
Further thoughts [see GS's 1856-6-27] on the nature of fluorescence, including that it is a transient phosphorescence.
Continues comments on fluorescence from letter of 1856-7-8; then shows mathematically that JH's solution for the problem of Mahomet's coffin [see GS's 1856-7-1] will not work.
Comments on one of the magnetism experiments JH described in his letter of 1856-7-14.
Says that Council of R.S.L. will reconsider whether William Pole's paper on color-blindness should be published.
Comments on the effect of intensity of illumination on the distinctness of the spectrum.
Comments about reflective power of metals.
Further comments on subject of GS's 1859-11-10; comments on several experiments involving light and color.
Partial repeat of letter of 1859-11-10, together with some considerations about the molecular behavior producing fluorescence.
Referring to some experiments in sound, GS proceeds to provide the theoretical basis for them.
Enquires whether JH wants a paper published in R.S.P.T. or in R.S.L. Proceedings.
Further about the paper referred to in GS's 1860-6-15.
About a request of JH for some palladium from the R.S.L.
Note to accompany sending of palladium [see GS's 1861-3-14].
Responds to a letter from JH, which GS has forwarded to Edward Sabine.
Requests that JH return a paper sent to him.
