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.
Been working on a new mirror for the 20-ft. telescope; very pleased with its performance. Asks CH to distribute his fourth catalog of double stars among the Prussian and German astronomers.
Sends volume of observations. Remarks on A. J. Fresnel's experiments. Lists errors in JH's treatise on light. Requests information on circular double refraction.
Thanks GA for the second volume of his observations; wishes the publications of the Astronomer Royal were as good; adds some comments on polarization of light by liquids, and then talks about observing Georgium Sidum [Uranus], and deals with the orbits of satellites of planets generally.
Is hesitating about a decision to come in to London, because his mother seems very ill.
About JH's mother's health, his coming to London, and daughter Caroline's vaccination. Is thinking about writing a 'discourse on science,' and complains about sitting up several nights, waiting for two stars to appear and now means 'to break the telescopes & melt the mirrors.' Found passage in Cicero to serve as motto for JH's Prelim. Discourse.
Expressing his grief over Isabella Stewart's approaching death. JH's mother is bearing the heat quite well. JH is busy observing again and his new mirror is excellent. Declines to sign [F. W.] Hope's certificate for R.S.L. because JH objects to council's current policies. Tell Peter Stewart that JH insists on paying for chinaware.
Inadvertently opened draft of Thomas Young's biography sent by HG, but sealed it immediately. Adamant that JH not see this before it is published. Will not change one word of JH's critique of Young's mathematics. If criticism offends Mrs. Young, then burn JH's manuscript.
Declines to write the Bridgewater Treatise on astronomy; also declines to comment on a paper due to lack of time and difficulty with the author.
