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.
Several items of R.S.L. business.
Provides detailed information about JH's responsibilities as President of the B.A.A.S.
Further arrangements about the B.A.A.S. meeting [see GP's 1845-5-10].
Still more about B.A.A.S. meeting arrangements, especially about the magnetic survey {see GP's 1845-5-23].
Brief note alerting JH to the presence of a foreign visitor.
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.
WP identifies date and people present at the time of the experiment referred to by JH in his 1845-11-9.
Sends copies of plates and details about them, and expects printing of JH's Cape Results to begin early in 1846.
Is sending JH some powder that HP thinks might be a good compound for polishing telescope specula.
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.
Invites JH to come to the magnetic conference meeting being held at the B.A.A.S. meeting.
