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.
JH, William Whewell, George Peacock, Humphrey Lloyd, and Edward Sabine are appointed by the B.A.A.S. to study systems of simultaneous magnetical and meteorological observations. They will be granted £89.
Hopes royal observatory at Cape of Good Hope will relieve Ordnance department. U.S. government agreed to pay for publication of observations there. A. D. Bache favors continuance of hourly meteorological observations in U.S. for one year. G. A. Erman will attend meeting at Cambridge. German translations by ES's wife.
Urged by G. B. Airy, ES withdraws earlier letter to JH and encloses letter with ES's opinions regarding continuance of [magnetic and meteorological] observations.
Asks JH to inspect first magnetic and meteorological observations from [Tasmania] and Toronto. Hopes North American observations will be increased.
Encloses bill from W. H. Allen & Co. regarding Breslau observatory. [JH annotation: Details of bill.]
Encloses newspaper clipping that reports JH is member of commission of inquiry on weights and measures. Protests that the poor are defrauded more by false scales than by nonstandard weights. Proposes remedy.
GP's views on continuation of magnetic observatories in colonies.
A strong letter on behalf of the provision of financial support for Professor [James David] Forbes, along with JH's personal statement of belief in the need to free distinguished scientists from teaching duties.

Thanks JH for a copy of a paper on prismatic study of the sun's rays, and for accompanying photographs.
Sends several samples of ferrocyanide JH had requested.
