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.
Relates the details of his accident. Gives equations and theorems.
Has had some more tourmaline sent. Gives some more equations. Chemical experiments.
Has dispatched the tourmaline. His chemical experiments. Circulating functions solving chance problems. [Letter postmarked 1819-3-29.]
Has received papers from J. B. Biot. Has been to the Customs and Excise. Functional equations.
Has just returned from Lincolnshire. Will shortly be visiting Torquay. Would like to call on him if convenient. Has heard of a vacant professorship at Edinburgh University and may try for it. Gives an equation of W. H. Wollaston's.
Is going to Edinburgh to apply for the post left vacant by John Playfair's death. Would JH and his father give him certificates and references? [Note by Mrs. CB to the effect that her husband has heard that James Ivory will not be contesting the professorship at Edinburgh].
Apologizes for the long delay in answering his letter. Relates experiences and hopes of success in his effort to obtain the position of professor at the University.
Has just returned from Edinburgh and found JH's letter awaiting him. Relates various experiences in Edinburgh. Recent discoveries in his chemical experiments.
Would he like to come for a trip down the river to see W. E. Parry's Expedition ships? Query regarding quartz crystals. Date for Pearsonian dinner.
Chemical news: decomposition of 'sulphuret of carbon' by J. J. Berzelius and Alexander Marcet. Analysis of 'azotane' and discovery of 'iode' by Humphry Davy. Congratulations on results of CB's examination.
Feigned reproach for CB's return to 'the Analytics.' Inquires about CB's 'Devonshire Ghost at Chudleigh.' Results of JH's chemistry experiments. Derides scientists who promote theory of 'akasch' as the one and only form of matter. Met Alexander Marcet in Greenwich.
Gratitude for CB's friendship. Chemical supplies and instruments. Describes synthesis of 'Sulphurane' [S2Cl2] and other experiments. Theories of combustion and acids. [Letter continued on 1813-9-21:] JH avidly studying law, against father's wishes.
CB has founded 'a calculus totally new and immensely powerful.'
Attending E. D. Clarke's mineralogy lectures. JH's analysis of dioptase.
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.
Made apparatus for showing rings between 'two Tourmalines.' JH's process for making hyposulfurous acid. Praises W. H. Wollaston's analysis of CB's 'Tonquinate.'
Sent JH's paper on mother-of-pearl and paper on hyposulfurous acid to David Brewster. Tell Brewster of JH's discovery of optical structure in crystals of bicarbonate of potash. Would Brewster accept paper from JH enlarging the definition of crystals?
JH understands CB to be a candidate for a professorial chair, and JH writes a warm letter of support.
