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.
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.
Has repaired the damage to his equatorial. Observed another of Wilhelm Struve's double stars last evening. Compares some of their star readings.
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.
It appears that Mineralogy has been assigned to him in the new manual. Comments on this and would like to know who will be writing the chapter on Geology as it is likely to overlap.
Congratulations on success [of JH's Cape Results], and happy new year. Encloses letter from Austrian ambassador with Emperor's testimonial to JH. Exchanged private notes with Count Jarnac regarding French king's intention to reward JH. Hopes that British government will permit JH to accept special honor from Louis Phillipe.
Acknowledges receipt of JH's Cape Results by Royal Society of Sciences of Göttingen.
Thanks JH for the gift of JH's Cape Results.
Gratitude for receipt of JH's Cape Results by university library.
Thanks JH for the gift of the Cape Results, and comments on his impending move to Lausanne.
Gratitude for receipt of JH's Cape Results [transmitted via George Bancroft].
Gratitude for receipt of JH's Cape Results by observatory of Central High School of Philadelphia.
Error in Leonhard Euler's value for Bernoulli's 21st number. Promotes HW's method of continued subtraction as a reliable means of proving accuracy of values for higher Bernoulli numbers.
Destroy all HW's letters claiming errors in Leonhard Euler's values for Bernoulli's numbers. Mr. Hensley of Trinity College found weakness in HW's continued subtraction method. Clarifies symbols HW used to represent P. S. Laplace's expressions of Bernoulli's numbers.
Continues explicating P. S. Laplace's formula for determining Bernoulli's numbers. Concerned that JH sees HW claiming too much for HW's continued subtraction method.
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.
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.
Demonstrates property of 'Coefficients of the terms of the Numerators of the Fractions which generate the odd powers of the Numbers of the Natural Series.' Claims this method can compute Bernoulli's numbers 37, 39, and 41.
[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.
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.'
All scientists named by GE, except [Adam] Sedgwick, will contribute to Admiralty Manual, but only one has a paper already prepared.
