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.
Should Mr. Morris, carpenter at Cranbrook, include canvas for covering dome, or will that be available at Cape Town? Improvements in WD's dome should be incorporated into Cape dome. Apologizes for WD's carelessness in managing telescope when JH visited.
Admiralty lords paid £316 to JH's account at Drummond's [Bank] for dome to house Cape of Good Hope telescope.
Proved accuracy of Leonhard Euler's values for Bernoulli's 27th number. Plans to test number 29. Will investigate Thomas Clausen's theorem, the generality of which JH appears to have disproved.
Acknowledges receipt of JH's Cape Results by Royal Society of Sciences of Göttingen.
Thanks JH for letter of 7 December, inviting him to Collingwood for Christmas. Apologizes for not coming. Received bad domestic news and was robbed. Will testify at Old Bailey.
Caroline Herschel, JH's aunt, is very ill, and not expected to live much longer. AK expresses some concern about some financial matters.
Preparing instruments and instructions for various expeditions. Discusses ES's wife's translation of [Alexander von] Humboldt's Cosmos and the [R.S.L.] Council.
Informs JH that RS will present a case for more than one medal to be awarded.
Is willing to assist JH, but feels that the Admiralty must instruct GA to do so [see JH's 1847-12-23].
Has sent out a number of circulars to JH as a member of the Royal Observatory's Board of Visitors.
Gratitude for receipt of JH's Cape Results by university library.
Will look into the affair of the overpayment of the telescope. Regarding geographical and hydrographical desiderata for the Admiralty Manual.
Has been requested by George Eden (1st Earl of Auckland) to contribute the botanical section to the manual to which JH alludes. Comments on this and the requirements for a manual of this type.
Is honored at George Eden's (2nd Baron Auckland) request for meteorological directions for atmospheric waves and barometric fluctuations. Will there be any engravings in the Admiralty Manual? The three annual barometric movements have occurred this year.
[George Eden] Lord Auckland seeks meteorological 'reports.' CW will contribute instructions on atmospheric electricity, photometry, and optical meteorology. W. R. Birt will report on meteorological instruments and wind observations.
Has just seen his letter [apparently requesting an article on mineralogy for the Admiralty Manual] on returning to his office. Is very busy at the moment with a survey of coal for George Eden (Earl of Auckland), but could probably help, given time.
Gratitude for receipt of JH's Cape Results by observatory of Central High School of Philadelphia.
Asks: for name of instrument maker JH recommends for construction of actinometers; which hydrogrameters should be taken to Mackenzie's River; and whether JH has any experiments he would like done in America.
Introducing Benjamin Travers, who intends visiting the Cape of Good Hope. Would welcome advice from JH.
Has now sent the letters and circulars to the various people in connection with the Admiralty Manual. Has not sent one to W. R. Birt, but will do so if JH thinks it advisable.
