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.
Is proposing to visit the continent after the Oxford meeting to make observations and intends taking some meteorological instruments. Would like JH's advice on some points regarding the large thermometer filled with a blue liquid.
In preparation for foreign travel, asks JH about instruments and method for measuring radiation.
Is grateful for JH's letter and offer of assistance. Will come to London earlier than expected so that he can call on him and discuss his problems before foreign travel. Would be glad of an introduction to Mario Gemmellaro and other scientists JH thinks would help him in his studies.
Regarding JH's actinometers, intends to compare their results when in Switzerland and would be pleased if JH has any determinations on them. Outlines the plan of his experiments. Thinks JH should publish an account of them before JF publishes the results of his experiments. Met L. A. J. Quetelet in Brussels. Intends visiting the Pyrenees.
Has postponed answering his letter until he has some worthwhile results to transmit. Local savants are unwilling to take much trouble but has met a German meteorologist, L. F. Kämtz, and together they have carried out observations on some of the mountains. Encloses some of the actinometer readings. Has 80 series of magnetic observations.
Returned suddenly from the continent and found JH's letter to his brother awaiting him. Outlines his reason for applying for the vacant post at the University and would welcome a testimonial from JH. Brewster is his chief rival. Gives a few observations on his recent trip to the continent.
Is sorry to trouble him again but would like a letter from JH that he can print with his testimonials, as David Brewster has now printed JH's letter, also [William?] Ritchie. Awaits the results before setting out for Europe.
