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.
Sends memoirs on magnetism of crystalline bodies. Notes that remarks on atomic mechanism of Iceland spar contrast with JH's views expressed in JH's Light.
Letter in application for Professorship of Experimental Philosophy and Chemistry at University College, Sydney.
Asks JH to keep memoirs JT sent with regard to JT's application for position at University of Sydney.
Thanks for papers on diamagnetism and lecture on 'slaty cleavage.' Compares with phenomenon of 'ringing coins' in mint. Explains with examples conformity of JT's views with JH's own on geological stratification. Praises simplicity yet completeness of JT's work.
Agrees with and asks permission to publish JH's letter in the Philosophical Magazine. Is going to Switzerland and Tyrol, where hopes to see phenomenon of glacial descent [see JH's 1856-7-31].
Clarifies letter on motion and structure modification of glaciers. JH thinks glacier ice unfavorable for exhibiting JT's phenomenon [see JT's 1856-7-30].
Sends sketch of lecture on structure and motion of glaciers. Wants to conduct experiments on physical properties of ice, and applying polarized light. Beyond paper, is interested in cleavage of ice.
Thanks for lecture on glacier cleavage. Wonders how 'regelation' occurs when two masses of ice at 32° are placed in contact.
Remarks on physical properties of ice and their bearing on glacial phenomena. Asks for help inventing term for idea of 'fracture and renewal' of glacial bendings.
Thanks for and comments on paper and lectures on 'diathermancy &c' of gases, scientific teaching, and solar chemistry. Regrets that JT mentioned all names connected with light research except JH's. Remarks on absorption of light, molecular vibrations.
Apologizes for not having seen JH's paper on spectra of colored flames and thus having overlooked JH's prior claims [see JH's 1861-7-21]. Will try to make amends.
Reply to JT's 'Remarks on Radiation and Absorption.' Calls non-absorption of air and vapor key to understanding meteorological phenomena. Remarks on 'radiant heat' from moon.
Gives account of observations on lunar radiation, including detailed description of experiments.
Does not believe surface of moon can radiate cold; perhaps new moon can. Explains this geometrically.
Clarifies that JT does not believe moon radiates cold itself, but effects are 'as if' it did. Relates this to atmosphere.
Finds JT's work on thermotics 'highly interesting,' although criticizes measurements of 'tenuity' of vapor, and explanation of scattering of sunlight and formation of corona around moon during eclipse.
Remarks on JT's papers on radiant heat and related role of moisture. Will send requested sample of rock salt. Explains difficulties using it and hopes JT will have better success, perhaps even repeating JH's experiments.
Finds JH's approval incredibly gratifying. Thanks for gift of rock salt. Is sending unscientific book; trusts JH's interests are broad enough to appreciate it.
Asks permission to print extract of JH's letter on heat spots of spectrum of rock salt sample. Hopes JH's son [Alexander] will speak at Royal Institution; JT would help with illustration. Wonders how blue color of water relates to sky color and polarization.
Likes JT's explanation of sky's blue color. Has difficulty with JT's explanation of polarization of skylight. Comments on absorptive powers of vapor and liquid.
