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.
Suggests John Lubbock's improvements in calculating planetary perturbations be discussed at a R.A.S. meeting. Plans to bring subject before the Council.
Is obliged by his note and will accordingly write to Richard Sheepshanks. Spot on the sun was very visible to the naked eye recently. Looks forward to seeing JH.
Verified Leonhard Euler's values for Bernoulli's numbers up to B=25 by method previously outlined and to be stated fully in this letter. Mr. Hensley [of Trinity College] proposes to revise incorrect values given in Penny Cyclopaedia. Computing a Bernoulli number by P. S. Laplace's formula takes three days. HW's method of continued subtraction requires only 24 hours.
Received three bills for £316 from Georg Merz and Sons, but JH's balance is only £19.
Thanks JH for suggestion on his method of Great Circle sailing. Further enquires over some cartographic matters.
Thanks JH for the gift of JH's Cape Results.
Requests reimbursement for £316 JH paid to [Georg] Merz for two bills owed by astronomer royal.
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.
Will edit a manual [Admiralty Manual] of Scientific Desiderata and Queries as requested by [George Eden,] Lord Auckland. Is AS preparing any material for this work? What is its content and when will it be ready?
Has been requested to prepare a manual of scientific instructions for the use of ship's officers, and is asking GA to prepare a section on astronomy.
Lord Auckland [George Eden] has asked JH to edit Admiralty Manual and proposed that WH write section on botany. Would WH do this and when could WH complete it?
Lord Auckland [George Eden] asked JH to edit [Admiralty Manual] for officers on surveying and exploring expeditions. Charles Wheatstone will prepare instructions for meteorological observations. Asks WB to write instructions on detecting 'atmospheric waves and barometric fluctuations.'
Is editing a manual for surveying and exploring expeditions. Asks WW to do section on tides.
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.
