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 JH's reply. Wishes she had obtained the autographs of Sir William and Caroline Herschel.
It was a great pleasure to receive JH's letter. Sees that he still remembers the day at Portsmouth. Hopes to collect and publish her father's letters and now returns those written to JH.
A note to accompany a paper by FP on the prediction of occultations and eclipses.
Thanks CP for sending volumes of Astronomische Nachrichten. JH notes missing copies in his collection, and asks how he might best obtain these volumes.
Is supplying JH with copies of his missing journals [see JH's 1869-1], and will send more later.
Thanks JH for the memoirs he sent to CP, who will reciprocate with some of his own.
Comments on exchange of astronomical works with JH. CP expects to improve the observatory library now that the Prussians have taken over Altona. Is making arrangements to carry out some pendulum experiments.
Inquires about the mathematical nature of the chords of music, offering some ideas of his own.
Comments on the mathematical ratios in chords at some length, in answer to RP's 1869-11-18.
More on the mathematical ratios of musical chords, and of dissonance [see JH's 1869-11-24].
Encloses letter regarding coinage under discussion in Parliament.
Explains cause of DS's double vision. Suggests corrective lenses [diagrams].
Cannot recall details or find documents regarding promotion of Charles Sterry to HF's assistant assayer in 1851. Remembers that Henry Bingley declined that position; it was then proper for HF to recommend someone.
Sees no likelihood that private meeting would resolve issue between JH and JS. JS misunderstood JH's argument on valuation of British coins and currency. Encloses JS's note to Editor of the Times.
Correction to be made in JH's biographical sketch of William Whewell.
Thanks for catching JH's error. Will write to the Times and substitute 'Mr. Smith, M.P.' for 'Col. Smith.' JH does not understand 'tariff of conversion' or how it will simplify calling in old coins. Prefers 'Binary system' to 'absolutely demonetizing silver.'
Forwarded both of John's papers on solar observations to William Huggins. Comments on solar prominences and spots, and on Eta Argus. Concern for Esther's fever. Report of 'great meteor' seen at Collingwood. Alexander Herschel came home from Glasgow with new device called 'bicycle' that amuses neighbors. Explains optics problem in telescopes. English system of measures.
Glad for Mary's recovery. Congratulations on John's promotion to captain. Suggests method to study solar prominences without spectroscope. [Letter continues 15 June:] Alexander Herschel reports that G. B. Airy tried this method unsuccessfully long ago, but JH is sure it will work.
Comments on WJH's appointment as judge in India. Contrasts legal practices in England and India. Reviews calamities WJH witnessed in India. Alexander Herschel is lecturing about eclipse at Royal Institution and Leamington. Family news. P.S.: Please write to W. E. Hearn in Melbourne regarding Hearn's book Government of England.
Glad that Emma's jaundice is over. Criticises metric system of measure. Encloses JH's response to Mr. Yates's letter in the Times on Geometrical British System. Upset by present resistance to anything English. This is what 'lost us...Neptune.' Would like to see Arabic translation of Outlines Astr. Relieved that 'shabby' French translation by [L. M. J.] Chevigné was stopped. Failure of gold standard in India. French and English coins. Suggestions on WJH's effort to introduce oaths into Indian justice system. Popularity of velocipedes [bicycles]. Family news.
