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.
Encloses a new prospectus of the Cabinet Cyclopaedia. Intends to write physical astronomy himself. William Whewell cannot write Sound. Has a stock in hand for three years.
Has some difficulty in producing his article on Light for the Cabinet Cyclopaedia as the publishers of the Encyclopaedia Metropolitana consider it would be harmful to their own publication.
Regrets to hear of JH's difficulties. Will consult the proprietors and let him know the answer later.
Has met the proprietors of the Cabinet Cyclopaedia. Would JH be agreeable to write an article on Astronomy or Optics, instead of Light? Will approach David Brewster regarding Light.
There is no truth in SL's statement to James Ivory regarding work on the figure of the earth belonging exclusively to JH. Has written to Ivory stating the facts of the misunderstanding.
When he last saw James Ivory at the British Museum, no mention was made of JH's name. Thinks the remarks of Ivory are caused by mental disease.
News that he has been elected an Associate of the Astronomical Society gives him pleasure. Does not have much time at the present to devote to astronomy. Hopes to visit England to obtain materials for a life of Edmund Halley.
Welcomes astronomical correspondence. Is grateful for having his name proposed as a member of the Astronomical Society. Comments on the work of the Observatory. Would like the memoir of Edward Troughton.
Sending his book on Theoretical and Practical Astronomy. Also sends books for Thomas Catton. Comments on some of the varying observations made at observatories.
Has he received the copies of the Vienna Observations? Encloses a small pamphlet of interest to mariners. What does he think of Josef Fraunhofer's micrometer for observing double stars? Is writing this letter on his birthday.
Sends books and observations for various observatories. Comments on recent astronomical work. Points out some discrepancies in John Pond's works. Praises the telescopes of Josef Fraunhofer.
Books per N. M. Rothschild have not yet arrived. Has arranged a standing order for the Vienna Observations. The Robert Molyneux clock can be dispatched at once. Agrees with JH that double stars are the test of a good telescope.
Has just heard that the ship carrying JL's clock arrived at Hamburg on the 5th. Gives the name of the Bank to which payment is to be made. Has used his Theory of Comets in a paper.
Has requested the government to forward payment for the clock. Regarding variations in the observations of F. W. Bessel, John Pond, etc. Has high opinion of Bessel's work. Has been sending books for Thomas Catton, but he never replies. How is Greenwich Observatory heated? Some observatories have troubles with dampness. Recommends book by K. W. Feuerbach.
Has received parcel from N. M. Rothschild. Hopes money for the Robert Molyneux clock will soon arrive. Encloses some items for him in Thomas Catton's parcel. Please accept Analytical Geometry. Hopes JL's two volumes on astronomy will be translated into English, and encloses copy of additions.
Thanks for books. Presumes Robert Molyneux has received payment for clock; this is a very good instrument, much better than [Thomas?] Young's. Encloses a work of his own, which he would like to see in the Transactions of the R.A.S. Sends propositions by a young Bavarian named K. W. Feuerbach.
Has doubtless received his Treatise on the Corrections of the Equatorials. Col. L. A. Fallon, head of the Austrian Survey, would like a Robert Molyneux clock. Can JH arrange to order one and send it via H. C. Schumacher. Encloses some notes on practical astronomy, which may be useful.
New Observatory is being planned on the lines of the new one being built at Obo in Finland. Would like an open letter from JH on the requirements for an observatory. Is there any news of the clock for [L. A.?] Fallon?
Approves of the plan for the observatory. Comments on some of the features. Good equatorial is a necessity. Will try to obtain a copy of the plan of the Cambridge Observatory.
Has sent money for Robert Molyneux clock care of Friess, the bankers. Is grateful for JH's trouble over the clock. Do not print certain observations he sent as they form the subject of an argument with F. X. von Zach.
