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.
Suggests change in composition of a pot to be made by [Apsley] Pellatt for an experiment.
Has been trying to see him, unsuccessfully, about the affairs of the Optical Glass Committee. Hopes that JH will not resign from the Committee now that he is no longer Secretary at the R.S.L.
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.
A furnace for glass making is under construction at the Royal Institution.
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.]
Sends a note with a letter from W. H. Wollaston to JH, dealing with glass making experiments.
Describes the tests JH made on a small glass prism of not very high quality, which JH has left at the Royal Institution.
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.
The furnace is breaking away at the top, and he encloses Joshua Ramsay's estimate for its repair. Thinks the present a suitable time for the repairs. Would JH speak to the Council?
Sends MF some older samples of imperfect glass. Talks about the way in which different kinds of glass should be layered in lenses.
Has made a piece of glass 5" square, which George Dollond reports is good. Proposes making a furnace at the Royal Institution. Does JH have any objections?
Writes a letter of introduction for a friend [Dr. Robinson] of a friend to MF. Comments favorably on MF's electromagnetic research.
Has received his letter introducing Dr. Robinson, but thinks that the latter is not a worthwhile person to know. Is pleased that JH likes his recent experiments. Owes a debt to JH's Prelim. Discourse.
Apologizes for sending a letter of introduction for someone recommended to JH, without first getting to know the third party.
Asks for copies of some of MF's writings to complete JH's set.
Esteems it a great honor to receive JH's request. Has searched through all his papers but has a spare copy only of the Third series. Is thinking of reprinting the whole series in one volume.
Saturday's experiments have brought a severe inflammation of the eyes so has been unable to use the aerolite. Returns it, but will try some experiments later if JH sends it back.
As JH has tried many varnishes he wonders if he has ever tried shellac. Has tried it on specimens of brass. Many thanks for his invitation.
Comments on MF's experimental results when an electromagnetic field affects polarized light.
