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.
Writes 'in haste' to thank JF for a pair of papers. Comments on Louis Daguerre's pictures in Paris.
Thanks JF for second edition of work on the Alps. Praises first edition.
Expresses appreciation for JF's publication on glaciers.
Suggests that JF use his instruments to compare the force of solar radiation at high and low elevations. Delineates possible methods for this experimentation, and lists results of similar experiments. Includes further information on the actinometer.
Congratulates JF on obtaining, after some difficulty, the Chair of Natural Philosophy at Edinburgh. Accepts offer to discuss meteorology with JF's relation Leslie Melville[?], and hopes to mention his actinometer.
Discusses reduction of barometric observations. Praises the Cape's climate.
Wishes JF well in [Edinburgh] and leaves addresses where JH may be reached [at the Cape].
On the preparation of paper to exhibit a thermal spectrum.
Thanks for JH's letters and the paper on photography with special reference to the effects of heat. Was present at the R.S.L. during consideration of a national observatory. Would like JH's opinion. Is working on a supplementary report on meteorology.
Hopes to add JF's name to B.A.A.S. Meteorological Committee, and to see JF at Cambridge meeting of the committee.
Is grateful for JH's letter and commendation regarding application for a government pension; will endeavor to carry out his recommendations.
Would like to know the degree of sensibility to heat of JH's paper. The paper of W. H. F. Talbot is useless for his purpose as only violet heat affects it. Did JH use a flint glass prism for his spectrum experiments? Has he ever used photography to show the impression of polarization and diffraction?
Thanks JF for papers and requests copies of those JH has borrowed; comments on JH's observations on solar heat, light, and lines in spectra.
Was pleased by JH's favorable opinion of his paper on the Vivarais. Finds JH's arguments concerning [John] Michell's theory of probabilities unconvincing. Will soon write a paper on the problems.
Regrets he has not been able to find anyone suitable for the chair of chemistry and natural philosophy at Sydney University.
Comments, after delays due to busyness, on JH's queries on the calibration of actinometers and gives results of experiments.
Gratitude for gift of JH's Cape Results. Just returned from geological tour of highlands with [Bernhard] Studer from Bern [Switzerland]. Hopes to purchase Madame Witte's 'model of the Moon...for Edinburgh,' if it has not been bought in London. Observed Neptune at Oxford in company with U. J. J. Leverrier, J. C. Adams, and Wilhelm Struve.
[Responding to JF's 1849-11-23], JH cautiously discusses various considerations bearing on the idea of sending an astronomer and a large reflecting telescope to the Cape.
When they last met, JH had promised to show him some of the wonders of his 20-ft. reflector. Is in town for a few days and would welcome the chance of visiting him.
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.
