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 a paper of his brother, Christopher Kemplay, on a theory respecting comets. Has already submitted it to James Challis, who objects to some points. Would be glad of JH's comments.
Invites JH to 10 May anniversary dinner of Literary Fund Society.
Asks JH about a comet JH had been observing. Notes the publication of J. S. Mill's System of Logic, describing it as closer to JH's than to WW's position.
There is to be another cliff-blasting. Gives details of travel arrangements.
Has received the two memoires on photographic processes and rays of the solar spectrum. Presumes JH has now received his own work on Physical researches. Comments on various electrical experiments.
Regarding the recent comet, believes it to be the one of 1668. Does not feel competent to comment on the proposal to change the names and boundaries of the constellations.
Offers JH information about, and maps of, Switzerland, as GA understands JH is going there.
Sends some specimens of photographs he has made by using bichromate of potash and an acid solution of nitrate of mercury. Gives details of a luminous phenomena he has seen in the S.W. and would like an explanation of it from JH.
Refers JH to page 18 of memoir of Manchester Literary and Philosophical Society, in which JJ, using 'the magnetic electrical machine,' succeeded in proving 'that heat may be generated by mechanical power without accompanying chemical change.'
Gives his proposal for the amendment of nomenclature for the northern constellations. F. W. A. Argelander's new celestial atlas. Regarding JH's southern map. The letter from the B.A.A.S. has been sent to Sir Robert Peel.
Introducing Professor Emile Plantamour, who is visiting England. Read JH's article on the rays of the solar spectrum with pleasure. Sends some articles by Plantamour from recent journals.
Met JH when he was residing in the Auvergnes. Since then he has had to leave France and now resides in England, where he is making a living teaching French and writing books. Would be grateful if he could add JH's name as a subscriber to a forthcoming work.
Unable to write before as he was packing for his journey home. Regrets none of his northern friends had seen the comet. Its orbit has been calculated as 35.3 years. Remarks on the tail of the comet.
Acknowledges with pleasure JH's kind note. Owes much to JH's book in the chapter on experimental methods. JH will doubtless find Auguste Comte's book worth reading. Would like a note of any errors in JM's book.
Urges JH to study a temporary index made by William Herschel that contains observations about types of zodiacal light.
Wishes JH had added his name at the head of the list of subscribers. Thinks he is being too cautious. AJ is responsible for the whole of the work though it appears under two authors.
Has been able to obtain some deodar seeds from Ireland. Sends them, together with some seeds of the Himalayan cypress. Hopes they will prove a success.
Thanks JH for earlier letter. Discusses JH's work on chemical action of light, with which he is familiar. Sends some papers for JH's comments.
Sends comet observations from W. S. Jacob. Obtains 'another excellent epoch of Gamma Virginis.'
Regarding Captain [Charles ?] Gray's letter. Robert Peel has written asking Francis Baily and W. H. Miller to do the 'Standards.'
