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.
Is grateful for the interest he takes in her son and for his letter. Comments on the German war. Has a house full of visitors. It has been very cold and they have been without water.
Sends an abstract of his research entitled 'The Effects of Tide on Planetary Motion.'
Has sent a work on the metric system in France, which includes JH's own valuable lecture.
Sending a long letter proving one of JH's theories regarding the sun and confirmation of one of William Herschel's observations concerning Saturn.
Thanks for JH's remarks on his own 'What is matter'; comments on these. Also regarding JH's theory of the sun's repulsive force and William Herschel's observations on the strange shape of Saturn.
Writes to thank WR for the paper on the thermodynamic theory of waves he sent; JH is too ill to respond or even to deal with the analysis in the paper. Nonetheless, JH does make some suggestions for WR's consideration.
Will mention JH's subject for investigation to Sir William Thomson. Is busy with Committee on Ships of War.
Requests publication of a notice of the recalculation by H. J. R. Petersen of the Gaussian constants of terrestrial magnetism.
Has sent a note to Nature stating the details of the grant paid by the B.A.A.S. to H. J. R. Petersen for magnetic observations.
Comments on use of 'air' lens rather than glass in some circumstances.
Is grateful for his comments on his own paper on vision. Would he refer him to the work by Mr. Chopal on lens.
Thanking him for his paper on heat developed in combination of acids and bases. Commenting on the various makes of calorimeters.
Note to accompany a translation of one of GE's writings; also comments on the 'reform' of the German language.
Has sent JH a copy of his new book [The Sun].
Comments on spelling reform being attempted in Germany and the United States, and being proposed in England.
Replying to JH's letter of 24 Jan. 1871. Thanking him for his suggestions. Has not seen JH's Cape Observations. Has seen report of R. W. Bunsen's experiments. Comments on these experiments.
Would like his views on the correct definition of a billion, to settle an argument.
Queries regarding the red glow seen during an eclipse of the sun.
Thanks RP for sending RP's Sun. Suggests a theory that the solar corona, rather than originating in the earth's atmosphere, is produced by reflection from meteoric dust. Informs RP that he has completed a catalogue of all observations of double stars.
Raises objections to JH's theory of the solar corona. Discusses possible existence of extensive meteoric dust in the solar system. Requests permission to dedicate a book on sidereal astronomy to JH. Asks JH whether his father in later years always used a front focus for his large telescopes and whether he saw the supposed four additional Uranian satellites with his 40-foot reflector.
