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.
Welcome back to London. Explain CB's demonstration of 'theorem in transcendental arithmetic.' JH's observations of 'new acid' [hyposulfurous] and optical phenomena in 'chrystals of nitre.'
Cannot meet CB in London this week. Has verified composition of [hyposulfurous] acid. Encloses crystal of 'sulpho=sulphite of lime.'
Fifth [1817] edition of Thomas Thomson's System of Chemistry shows previous discovery of JH's 'new acid,' but its reported composition is wrong.
Would like comments on the accompanying paper on functional equations. Stephen Lee [of the R.S.L.] has revived the reading of Isaac Newton in Paris.
Comments on his paper sent previously [see JH's 1818-3-10]. Time has been taken up with mineralogy. Is sending some samples.
Please send the third volume of J. E. Montucla's Histoire de mathématiques. Is running into difficulties with his history of mathematics owing to lack of translations. Regarding kaleidoscopes. Has been reading David Brewster's experiments on Mother of pearl.
Cannot help him with the Commercium epistolicum [by Pierre Fermat]. Leaving town for a few days. Regarding the kaleidoscope.
Thanking him for the third volume of J. E. Montucla's Histoire de mathématiques. Gives functional equations for his comments. Is afraid that he will not be able to visit Cornwall this summer.
Wishes to leave town and spend a few weeks in Torquay. Would JH join him? Has new theorem on functions.
Gives some analytical equations for his comments.
Wants his support for his own application for a post on the Board of Longitude.
When he comes up to town would he please bring Biot's work. Wants to show JH a paper on series. Has just had a visit from Edward Sabine, newly returned from Greenland.
Astronomer Royal's post at Greenwich vacant; hopes JH will try for it. Has not been successful in getting on the Board of Longitude. Hopes to spend a fortnight in Paris after Christmas.
Thanks CB for his advice about applying for the post of Astronomer Royal when it becomes vacant, but does not think himself qualified. Will not be able to come to London this weekend. Regarding his new acid.
Urges JH to apply for the Greenwich post. Quotes extract from Thomas Thomson on chemistry. Gives equations for his comments. Has found a new method of producing household gas.
Thanking CB for CB's further remarks on the Greenwich post. Further regarding his new acid.
Remarks on CB's article on analysis and the examples used. Hopes to see him at Christmas; then they can talk about the projected visit to Paris.
Regarding one of JH's papers in the Analytical. P.S. dated 19 Dec.: Is glad to hear he would like to go to Paris.
Hopes CB will visit Slough soon to discuss the proposed trip to Paris. Gives a sketch of his investigations on theorems connected with series.
Will visit him at Christmas. Regarding the theorem quoted by JH [see JH's 1818-12-20].
