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 for the extract of his paper. Comments on this and his own discoveries on the polarization of light. His fees for the articles will pay his subscription to the Royal Society of Edinburgh.
It has been a long time since he last heard from him. Very busy with professional pursuits. Congratulations on receiving the Copley medal. Would like an abstract of his article on aberrations in chromatic lenses. Comments on this.
Has been unable to answer his letters due to the King's visit. Refrained from writing on hearing of the death of W. Herschel. His paper on the absorption of light will appear in the next number of the Transactions of the Royal Society of Edinburgh. Comments on this. Grateful for any astronomical news. Advice welcomed on memoir of W. Herschel.
Regarding the change of ownership and policy of the Edinburgh Philosophical Journal. Would like a paper from him for the first number. Marked 'Private.'
Regarding corrections requested by JH in a printed article. Ill health and overwork applies to him also. Pleased to hear of the work of the Optical Glass Committee. Comments on this.
Would have answered his last letter sooner but has been confined to his house. Encloses specimen of calcareous spar. Has in the past carried out many experiments on this substance. Is he satisfied with a statement in the Optical Glass report? Missing Transactions for the library.
Thanks for paper on light, which he has only just read as it was mislaid. Grateful for the acknowledgement of his scientific labors. Comments and queries regarding the paper in the light of his own experiments. Wishes to reprint parts of it so would be grateful for several plates.
Letter to [Edinburgh Philosophical] Journal calling attention to 1809 article by [Paul] Erman of Berlin, which some say anticipated JH's 1824 Bakerian lecture on 'Motions produced in fluid conductors when transmitting the Electric current.' JH compares both papers, admits Erman's priority on some theoretical points but claims originality for JH's experiments.
Arrangements for paying dues to the Royal Society of Edinburgh; some comments about light passing through crystals.
Clarifies areas of disagreement with DB in JH's explanation of the results of colored tints of light passing through polarizing crystals.
Sending all his papers on the deviations of tints, suitably amended to give DB due acknowledgement. Queries regarding some of DB's statements. Supports his theories in a new paper he has written for the Cambridge Philosophical Society.
Accompanies a paper JH was submitting to the Royal Society of Edinburgh. Discusses motion of light rays in Apophyllite and various optical writings of DB.
Some comments on sun spots based on William Herschel's ideas; considering a collection of William Herschel's writings but publishers not interested.
Forwarding to DB, through Hans Christian Oersted, a paper on caloric by Marc Seguin.
Some comments on observations by Continental observers; matters related to sending books and papers.
Praises old Edinburgh Philosophical Journal. Promises to send DB some materials for publication.
Has received copies of reprints from Lyell. Points out errors in a printed paper of his. Has been unwell and very busy of late. Would like to add DB's name to the Optical Glass Committee.
Asks DB to sign a certificate for the candidature of William Ritchie for admission to R.S.L.
Sending DB a draft of a paper; comments on quality of a chromatic lens (that of [Charles] Tulley's telescope using Pierre Guinand's glass).
Sends an abstract of his paper on observations relating to the practical construction of telescopes [JH's 'Practical Rules,' 1822]. Would like 25 copies for distribution. His recent experiments with polarized light.
