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.
Agrees with JH that the Government Observatories at the Cape and St. Helena require mature consideration. Greenwich observations are a different matter and were suggested by the R.S.L. Committee of Physics. Has directed the minute to be sent to JH. Has been studying the wet bulb question.
The magnetic and meteorological observatories were never part of any other system. Is not certain whether the Visitors had anything to do with these observatories. Captain Herbert in an Indian journal has proposed a formula for the wet bulb thermometer. Has arranged for the notice to be sent to JH.
The President was requested to write to the East India Company about the observatories. Continuance of the magnetic observations at Greenwich was referred to the Committee of Physics. Cannot find where Nicolas Clement-Desormes's observations are published. Has been studying the wet bulb problem. Capt. Herbert has denounced the article on hygrometry in Brewster's Encyclopaedia.
Has been with Philip Melvill of the East India Co. discussing the printing of the observations. Would it be a good use of JH's photographic papers to take a reverse of William Parsons' (3rd Earl of Rosse) drawings of nebulae? Cannot obtain Nicolas Clement-Desormes's or John Sharpe's papers. Doubts if the mode of measuring latent heat hitherto used can be recommended for accuracy.
Has received the books. Began with Karl Holtzmann's and finds the reasoning at fault. Comments on this. [Marked 'not sent.']
Question of procedure about considering the magnetic observations for publication.
Wants to know if GA's opinions [see GA's 1845-4-1] are available for public information, or only for JH.
Is trying to organize a meeting of the Magnetic Committee before the meeting of the B.A.A.S. in Cambridge, to deal with reporting and committee membership.
Further to arrangements about meeting [see JH's 1845-5-30].
Arranging a meeting of the Magnetic Committee to set the agenda for the magnetic conference to be held during the B.A.A.S. meetings in Cambridge.
Comments on WW's publication on education [Liberal Education, 1845 ?], especially as it applies to the teaching of mathematics. JH has been teaching JH's son William mechanics by WW's book on the subject.
No news yet about the request to Robert Peel for money for magnetic observations.
How does one jog the memory of the First Lord of the Treasury [see GA's 1845-10-3]?
About a number of astronomical matters, including double stars. Provides observations and calculations for Gamma Virginis. Also comments on lunar models.
Asks JH's opinion on a paper on magnetism by Karl Reichenbach, which has some 'very extraordinary' statements.
Regrets to learn that JH is still suffering. Advises him to come to London for examination.
Was gratified to hear of the improvement in JH's health. Hopes it will progress.
Is very critical of a series of three foreign memoirs that JH believes certainly should not be published. Concludes with a strange postscript on catalepsy.
Informs JH that he is to work with a committee of the B.A.A.S. to prepare a map of the distribution of coal around the world.
Expands on the work of the coal map committee [see JP's 1845-7] by sending along the resolution that created it.
