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.
Encourages GA to ask the Admiralty about the implications of Robert Peel's statements [see JH's 1845-9-29 or earlier].
Will now work with S. J. A. Compton, the President of the R.S.L., to try to get fair treatment for another applicant for the Admiralty money [see GA's 1848-9-25].
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.
Further clarification to JH's 1848-10-26.
Reliability of measuring instruments used in scientific and public surveys. Approves George Peacock's suggestion to revise survey tables for use by non-scientist surveyors. Schools should teach only legalized systems of weights, measures, and money.
Has not heard from Thomas Maclear [see GA's 1844-3-12]; has the Cape equatorial object glass been dealt with?
Tells GA about a new comet becoming visible.
Some concerns about GA's intent of attaching magnetic and meteorological observations to the R.A.S.'s Astronomical Observations [see GA's 1849-3-28].
Has requested of Admiralty £485 for equatorial telescope, from Merz in Munich, for Cape of Good Hope Observatory. Ask JH to estimate cost for 'next year's Estimates.'
Admiralty has approved equatorial telescope for Cape of Good Hope Observatory. Advise JH to order it from Munich.
Seems clear that JH's 'falling star' [see JH's 1845-4-29] was the same one reported by a correspondent of GA's as having been seen in Nottingham; in a postscript JH is not so sure.
Gives formula for defining the measure of the scale of an actinometer.
There is a need for a meeting of the Committee of Physics [R.S.L.] to discuss the current method of making temperature corrections for magnetic observations.
A committee meeting is being called [see JH's 1846-10-22].
Provides information [see GA's 1840-8-13] based on equipping the Breslau Observatory; also comments on lawyers, meteor showers, and photography.
Has passed on GA's note to Edward Sabine; cannot write more because his hand shakes too much, having just made a snow-man for the children.
Sends a letter from Humphrey Lloyd for GA's comments.
Thanks GA for his comments [see GA's 1842-1-18]; hopes that GA would be willing to have such statements, and other similar statements, made public.
