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.
Comments on MF's experimental results when an electromagnetic field affects polarized light.
Has just seen mention of MF's latest experiments showing the connection of light and magnetism. Comments on these. Proves some of his own theories to be correct.
His letter was a great encouragement and pleasure. Comments on his own and JH's experiments with light and magnetism. Contemplates a further series of experiments but requests JH not to mention it. Is at Brighton for a rest.
Sends details of an experiment he would like MF to carry out. Cannot do it himself as he has no suitable glass.
Has received his letter and suggestions for the experiment. Has ordered the glass from Newman. Is very busy so may not be able to carry out the experiment for a week or more. JH must keep the results secret for the time being.
Has procured some glass rod fit for the experiment. Comments on the results. [Robert] Hunt has been working on crystallization and magnets and has told him of JH's interest. Grieves to hear of his illness. His paper in JH's hands will be left for the time being until he has more time.
Has opened the sealed paper MF sent, and JH is now returning it.
Has a sufficient quantity of heavy glass at his disposal and offers some to JH.
Will be showing some experiments in the laboratory next Monday to G. B. Airy, François Marcet, and a few others; JH would be welcome.
Leopold Gmelin's Handbuch der Chemie contains all JH requires. If he does not have access to it will send it to the R.S.L. for him.
Finds he made an error last night due to his bad memory. The Duke was asking for JH; hopes he met him after Richard Owen's discourse.
Enclosing the tickets. Hopes the whiskey will be good.
Thanks MF for sending a 'healing liquid.'
No doubt he is aware of F. A. Nobert's work on glass. Has received from him a paper, which he intends communicating to the R.S.L. Thinks JH may like to see it.
The accompanying book was addressed to MF but inscribed to JH, so he considers it belongs to JH.
Did as JH wished with the papers. Is busy with magnetism and lines of force. Sends a couple of printings.
Has not read up the different treatises on elementary chemistry but gives three authors: George Fowne, Thomas Graham, and W. T. Brande. Has sent [Rudolf?] Wolfe's letter to Edward Sabine.
Sending a letter he has received from [Rudolf?] Wolfe. Will send it to the R.S.L. or the R.A.S after JH has seen it, whichever he thinks best.
On the periodicity of sun spots.
More on lacunae in JH's set of MF's writings [see JH's 1838-10-3].
