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.
Indicates the best way for the glass subcommittee [of the R.S.L.] to deal with the results of glass experiments at the Royal Institution [see MF's 1827-11-3].
Informs MF that JH has been called to serve on a grand jury and so may have to miss some glass subcommittee meetings. [This note enclosed the letter written by JH on 1827-11-6.]
Describes the tests JH made on a small glass prism of not very high quality, which JH has left at the Royal Institution.
Sends MF some older samples of imperfect glass. Talks about the way in which different kinds of glass should be layered in lenses.
Sends a note with a letter from W. H. Wollaston to JH, dealing with glass making experiments.
Chemical constitution of meteorites. JH suspects lead-iron alloy. Believes this has not been proposed before. Send specimen for JH's analysis.
Rearranges a meeting of [the R. S. L.'s Glass Committee] to take place at the Pellat and Green's Glass House in Holland St.
Comments on the intent of remarks appended to a paper of MF's.
Suggests change in composition of a pot to be made by [Apsley] Pellatt for an experiment.
Hopes to meet JH in London, and to finish building for R.S.L. soon. Discusses various prisms for experiments. Mentions 'neat' process for drawing uranium from iron.
Proposes an adjustment in the proportions of the ingredients in the next glass-making experiment.
Discusses origin and reactions of enclosed borate of lead. Postscripts on parallel strata in glass.
Thanks for the copy of his paper and errata. Received a packet of specimens of glass, which he presumes came from MF. Regarding the specific gravity of some of the specimens. Comments on further experiments to be made.
Has read his paper on vaporization with much interest and can see no objections to its arguments. Comments on some of the details.
[More detailed version of JH's 1826-5-26]. Has mentioned it to Humphry Davy.
Hears that the Board of Longitude is to be dissolved; it will therefore be necessary to seek a new source of income for the continuance of the Optical Glass experiments. Will be guided by MF's wish whether to continue the experiments. Charles Anderson has showed him curious experiments with the fusion of Fluor with clay.
