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.
How does one jog the memory of the First Lord of the Treasury [see GA's 1845-10-3]?
Is very critical of a series of three foreign memoirs that JH believes certainly should not be published.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.
Do as JM suggests. Further comments on JH's dispute with the theories of Auguste Comte.
S. J. A. Compton [Lord Northampton] has addressed a private letter to Robert Peel [see GA's 1845-10-9].
AS JH understands the matter [see GG's 1845-12-23], GG is the only knowledgeable member of the committee, and so it will be up to GG to present information and propose some means of moving ahead. JH makes some critical remarks about the nature of B.A.A.S. committees.
Robert Peel has suggested that the Admiralty has money available to pay for improvements in scientific instruments of value to navigation.
Encourages GA to ask the Admiralty about the implications of Robert Peel's statements [see JH's 1845-9-29 or earlier].
Asks WP to recall the particulars of an experimental session [see WP's 1823-3-11] where JH tried to demonstrate the polarization of light by an electrical current in a coil of wire.
Sends copies of plates and details about them, and expects printing of JH's Cape Results to begin early in 1846.
Is now finally empowered to order the telescope he inquired about [see JH's 1843-9-2].
Some modifications to the telescope ordered [see JH's 1845-11-7].
Gives reasons why telescope for Cape Observatory should be as perfect as possible. Doubts that its 'finder' is adequate.
Results of testing at Collingwood by JH and W. R. Dawes of two 8-inch object glasses made by William Simms for Cape of Good Hope observatory.
Supplement to JH's report [see JH's 1845-10-10] on object glasses for Cape Observatory. Different results at lower powers when observing planets.
B.A.A.S. resolutions include closing H.E.I.C. magnetic and meteorological observatories at Simla and Singapore but continuing those in Bombay and Madras. Propose magnetic survey of India Sea.
Rejoices that RH is studying orbit of Mu2 Bootis. Suggests way to simplify calculations. Compares orbits for Gamma Virginis calculated by various observers. Notice of systematic errors.
Responds to recently printed letter by James South. Denies South's assertion and confirms that William Herschel did discover two interior satellites of Saturn with 40-feet reflector telescope in 1789.
Privately acknowledges lack of clarity in William Herschel's report of discovering Saturn's inner rings, but JH was hurt by James South's public refutation of that discovery and by [T. R.] Robinson's abrupt refusal to communicate. Reviews WH's papers to demonstrate falsity of South's claim. Asks TM's opinion.
Encourages board of directors to pay for publication of magnetic and meteorological observations made at four H.E.I.C. observatories. Names countries that participated in global survey.
Will write to Court of Directors to ask H.E.I.C. to publish observations from Indian observatories. Needs to know where observations are stored, whether Humphrey Lloyd has reduced them, ES's reasons for making this request, best method for preparing data, and probable expense. Must go to Slough tomorrow to do business with former tenant.
