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.
Thanks JH for his comments on PR's plan for London drainage. Asks another question regarding the system.
Thanks TR for his paper on magnetism and his article on speculae. Discusses [J. P.] Gassiot's work on galvanic stratification. JH's health is better.
Thanks PR for the sewerage book. Suggests a method of disposing of sewage in the river. Concerned about solid waste, which he thinks should be used as fertilizer.
Asks for JH's autograph. Aspires to be an astronomer. Was impressed by JH's feeling for humanity at the Leed's Young Men's Christian Institute.
Acknowledges JH's letter and thanks him for it. Praises JH profusely.
Sends Mathematical Monthly. Asks for a list of JH's publications. Would also like a photograph and biographical sketch.
JH's improved health would allow him, if asked, to chair the Chemical Section at the B.A.A.S meeting. Notes that JH, G. B. Airy, William Whewell, and George Peacock have been appointed to a committee to cooperate with the B.A.A.S. committee dealing with the continuation of terrestrial magnetism observations.
Discusses ellipticity and results of [G. B.] Airy and [F. W.] Bessel. Also, [Alexander von] Humboldt's magnetic results.
Must hold to 1/290 as measure of ellipticity. Committee agrees to recommend continuance of magnetic observations if JH will continue to do what he has done in the past.
Sends G. B. Airy's remarks concerning ES's last communication. Discusses future of observatories. Asks ES to indicate which observatories he feels are most important.
Wife not well enough to visit Collingwood. ES may come next week. University of Kasan Observatory may assist British endeavors. Mr. Bolyani is very capable.
Sends section X and earlier paper on Kew and Nertschinsk disturbances, which supply key to theory of magnetic disturbances.
Sends vol. 4 of [Alexander von] Humboldt's Cosmos. Would like to share information gathered in India.
WS's brother-in-law [George Peacock] has died after an illness.
Feeling better, but writing still painful. Writing articles on meteorology and geology for Encyclopaedia Britannica. May use information from her Physical Geography.
Lists facts from various astronomical catalogues, such as the number of fixed, double, and binary stars. Discusses parallax. Thanks her for second edition of Physical Geography.
Enjoyed visit of Louisa [Herschel Marshall]. Wants copies of JH's new articles. Is witnessing a solar eclipse, in which half the disc was covered, as she writes.
Will ask Parisian doctors for information JH wanted and transmit it immediately. Hopes change of air will improve JH's health. Regrets JH is not closer to the capital so that the best doctors could help. Is writing Mr. Royer to ask him to write to JH.
Expects that JH has received instructions sent through Mr. Royer. Informs JH that HR is sick and will visit some friends to recuperate.
Has read with much pleasure JH's dissertation on meteorology published in the Encyclopaedia Britannica. Requests an English version. Sends several memoires on meteorology. Regrets not being able to send a complete set. Asks JH to send other works for the Observatory of Havana.
