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.
Believes JH expressed support for pension for surviving child of Thomas Henderson. Comments on this, stating his own view that she is already well provided for.
Discusses prospects for meteorological committee of B.A.A.S., on which they both will serve. Lacks time for it. Does not need hourly observations made by Committee of Physico-Mathematical Society of Edinburgh.
Gives JF permission to use JH's letter to JF's brother in any way JF sees fit to obtain the Chair of Natural Philosophy (at Edinburgh), but still does not wish directly to promote JF's selection. Briefly discusses results of JF's experiments with the actinometer.
Mentions letter from William Whewell sending JF JH's interesting but puzzling meteorological results. Will communicate them to a Dr. [John?] Davy at Malta. Has been busy preparing lectures. Made a short tour in England last summer. G. B. Airy has been awarded the Lalande Medal.
Unable to assist JH's friend Major [Abraham] Cloete as JF was away from home. Comments on results of JH's table and JF's own papers and scientific occupations. B.A.A.S. would welcome JH's ideas for meteorological work. S. D. Poisson has published a new work on heat, in which he attacks J. B. Fourier.
Discusses methods of magnetic observation, JH's actinometric readings in the Cape, and the need for more physical observatories.
Sympathizes with JH's feelings of regret over actinometer readings. Has procured a new thermometer and carried out experiments toward correction of actinometers.
Thanks for medal of the Royal Society of Edinburgh.
Comments on JH's Treatise Astr. in the Cabinet Cyclopaedia, mentioning its continued publication, misstatements he wishes to correct, and his addition of A. de Gasparis's newly-discovered planet [Hygeia].
Comments on JF's article about glaciers and particularly on the solid, liquid, and other states of matter.
Expresses thanks for several of JF's writings and relief at JF's good health. Comments on JH's own writing.
Outlines theory behind and method for preparing thermographic paper, which allows observers to determine 'what share each ray of the spectrum bears in producing the observed total effects.'
Sets up approximate meeting time, depending on his family's timely departure to Antwerp, with JF at the R.S.L. apartments.
Calls JF's attention to an article in which an answer is attempted to JF's objection to 'the argument from probability of a physical connection between individuals of a double star.'
Describes difficulties in attempting to produce good meteorological register and establish national meteorological observatory.
Requests information about actinometers in JF's possession, and provides further information regarding their use.
Sends new edition of JF's Travels [through the Alps of Savoy]. Hopes JH will examine the theoretical part.
Believes all actinometric measurements made are useless because they did not take into account the rate of expansion of the liquid, which is not constant.
In preparation for foreign travel, asks JH about instruments and method for measuring radiation.
Sends thanks and congratulations for paper verifying electric origins of all magnetism. Will give JF an actinometer with complete instructions. Includes some instructions for obtaining and using it. Sends regards to Mario Gemellaro, should JF go to Catania.
