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.
Will see him in London. Is getting on with his supplement. Has seen CB's latest paper in the R.S.P.T. Regarding Mr. Hirsch's theories on equations.
Is overwhelmed with work in algebra, studying S. F. Lacroix's work, grinding and polishing mirrors for JH's father. Sends thanks to Whitfield family for songs. Comments on controversial Cambridge news. Sends news of friends.
Asks about WW's mathematical investigations. JH's book on algebra is progressing. Describes mathematical investigations by [Edward] Bromhead in calculus of factors. Misses Cambridge.
Agrees to write several articles on mathematics, and one on astronomy based on William Herschel's work.
Is pursuing mathematical investigations with Charles Babbage. Asks WW to check whether George Peacock is progressing in printing the Supplement to Lacroix's volume.
Has been trying his hand at functions; quotes some. Hopes to visit him at Torquay. Push on with the supplement.
Sends one mathematical article on isoperimetrical problems and asks to write the article on variations as well.
Discusses plans for an edition of the mathematical writings of the late William Spence, to be edited by JH.
Regarding his projected supplement. Calculus of deviations. Naming of periodical functions. [John?] Spence's manuscript.
Poses mathematical problems for 'polar equations of conic sections.'
Discusses editorial actions taken by JH in editing mathematical manuscripts of William Spence, including materials recently sent to JH by JG.
Invites WW and [Thomas] Leybourn to join JH for dinner while Charles Babbage is visiting JH at Slough.
Asks about Cambridge friends, and that JW check on various items JH left there. Sends news, especially on 'mineralogizing' with [I. H.?] Jephson and Charles Babbage. Comments on recent deaths of J. A. Deluc, and of Princess Charlotte.
Regarding W. G. Horner's paper. Printing of their book. Is preparing a paper to submit to the R.S.L. on a mathematical subject. Will be in town shortly and will visit his laboratory. Has received more sheets of [John?] Spence's essays.
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.
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.
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.
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.
Thanks WW for and expresses agreement with WW's analysis of Simon Stevin. Describes experiments JH is conducting on the polarization of light.
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.'
