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.
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?
Mr. Murray will bring to DB two papers by JH, one on hyposulfurous acid and one on mathematical analysis, plus requested abstract of JH's and William Herschel's 'last papers' in R.S.P.T.
Grateful for WW's comments on investigations of [Simon] Stevin. JH's work on polarization of light. Discovery of multiple axes of polarization was preempted by David Brewster. Diagrams polarization of niter crystals and Iceland spar.
Will sail tomorrow for Calais. Could not find Mr. Armstrong in Dover.
Arrival in France. Travel companions. JH and Charles Babbage will go to Institute tomorrow to visit J. B. Biot, S. D. Poisson, and other mathematicians.
Working in law office of [F. W.?] Sanders. Attended R.S.L. last night. T. W. Hornbuckle offered JH position as subtutor at St. John's College, but JH declined. Describes paper on minerals that JH submitted through E. D. Clarke to Geological Society. Charles Babbage just made creative mathematical discovery.
Copy of JH's midsummer examination questions—17 on Greek drama, 22 on Mechanics—at St. John's College. Currently reading P. S. Laplace's Système du monde, which confirms WH's theory of galaxy formation. T. W. Hornbuckle reports that money has been received from Bruce & Co.
Duties at St. John's College. James Grahame's father is arriving from Glasgow. [James] Wood is working to get Grahame into college. Ask cousin [Mary Baldwin] for address for Mr. Rogers. Recalls JH's summer vacation.
JH's hypothesis on nebular vortex and formation of solar system. Has other ideas about molecular forces and comet tails, but will wait to learn whether WH wants to hear them. JH burned over 100 pages of notes on these speculations. Will return to Slough in mid-December.
Describes JH's public Latin examination in algebra yesterday. James Grahame and sister were dangerously ill, but Grahame returned to Cambridge. [Addendum:] Newspaper clipping naming students (including JH) who received B.A. degrees at Cambridge on 16 Jan. 1813.
Two weeks of examinations begin tomorrow. Experiments writing with glass pen. Describes glassmaker's methods. Suggests application to micrometers.
