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 accepting dedication. This has brought AQ utmost pleasure. Has dedicated few works. Expresses his esteem for JH's character and talent.
Gratified by JH's 'sympathy and approbation,' and that JH's writing and spirit remain 'firm' and 'fresh.'
Thanks for work on diamagnetism and magne-crystallic action [Researches on Diamagnetism (1870)], which JH is excited to read. Mentions long-abandoned plans for magnetization experiments. Envies those who can see JT's 'magic' experiments at Royal Institution.
JS thanks HM for having copied out for JS a letter of JH's apparently regarding JS's paper. JS admits 'It never occurred to me even in dream to get the opinion of Sir John Herschel on my poor essay.'
Thanks JH for favorable opinion of JS's paper, as expressed to Hugh Martin. Comments on JH's remarks on allotropy, and on connection between physics and life. Believes Germans preeminent in physiology.
Thanks for paper on action of rays 'of high refrangibility' on gases and vapors. Attempts to understand reflection of wave motion on particles with diameters 'incomparably smaller' than length of wave.
ES has been forwarded letter explaining why 'great telescope' at Melbourne will not work and suggesting construction corrections, on which JH, who believes such 'a priori condemnation' unjustified, comments herein.
Cannot attend Eclipse Committee meeting but suggests that an observer carefully look for planets interior to Mercury's orbit, which would, if existing, reach conjunction during total solar eclipses.
Approves of ES's actinometric methods, but wonders about absorbent power of alcoholic liquid. Laments 'sad conclusion' to career of 'Hansa,' and hopes her companion is more successful.
Discusses significance of Col. Napier's pendulum observations to research on earth's constitution and gravitation.
Thanks for suggestion-filled letter. Remarks on blue color of water.
Thanks for many works, especially double star catalogs, about which JH requests further information, and which will help JH's attempt to compile digest of all measures of all known double stars.
Thanks for telegram and has dispatched papers about absorption power of actinometer liquid. Hopes letter written in Lady Sabine's handwriting does not indicate serious illness of ES.
Thanks JH for mention of him in Outlines Astr. Sends detailed observations of Alpha Centauri system.
Sends an abstract of his research entitled 'The Effects of Tide on Planetary Motion.'
Is preparing a catalogue of all double star observations, and is having much difficulty with the observations of J. H. Mädler.
Expresses concern over Church of England schools. Suggests appeal to raise funds.
Acknowledges JH's comparison of Barclay Observatory results with those of other observatories. Sends more observations.
Tests several possible rules for curving lenses including W. L. Newman's and [Thomas] Cooke's. Tries to put W. L. Newman's rules for lens thickness-to-curvature ratios in a simpler equation.
Has JH seen R. A. Proctor's theory regarding the Milky Way?
