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.
Asks for latest chemical information on platina groups, or 'Platinoids.' In trying to remove platina from mineral specimens JH may have found new metal. Describes its characteristics. P.S.: Keep this information private.
Thanks for information [on latest platina research]. Has encountered 'a totally new metallic chemistry.' Searching for papers by Mr. Gros and Mr. Beiset. Describes JH's experiments with 'Platinoids,' which JH named like asteroids: Heberum, Astraeum, and Neptunium.
Encloses JH's letter of 11 Oct., which was not mailed to RK. Discovered traces of titanium in Astraeum. Puzzled by saline compounds that appear in JH's experiments with 'Platinoids.'
M. McCann sent his paper to JH for communication to the R.S.L., which he did, but does not know the outcome of it. Was unable to report on it as his own knowledge was not modern enough.
