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.
Will leave London for several weeks when ES's wife is well. Alexander von Humboldt is pleased with English translation of Cosmos. Preparations for magnetic research in Australia, Bavaria, [British] Guiana, and Mauritius. [JH annotation: Routing list to G. B. Airy, George Peacock, and William Whewell.]
Prospects for making magnetic and meteorological observations at Peking, which is more desirable than Shanghai or Hong Kong. Hopes for popular review of subject in Quarterly [Review].
Forwards latest computations of lunar diurnal variation in horizontal force of terrestrial magnetism at Cape of Good Hope. Describes method used by Archibald Smith to distinguish lunar from terrestrial magnetism.
Regrets being absent when JH and sons called at [JG]'s home. Hopes to show JH some peculiar electrical phenomena that [JG] observed. Encloses two letters from [W. H.] Miller.
Summarizes for JH the more extensive report appended, which recommends to the R.S.L. and the B.A.A.S. the establishment of magnetic observatories in several Colonial locations.
The Treasury has, with great reluctance, agreed to establish one magnetic observatory at Peking, rather than the extensive plans proposed [see Edward Sabine's 1858-6-26].
Given the Treasury stance [see Richard Owen's 1858-12-18], GA sees little point in setting up one station [see JH's 1858-12-18].
Wants someone else to take responsibility for committee on magnetic observations [see JH's 1858-1-25]; GA proposes Edward Sabine.
Would support the establishment of Colonial magnetic and meteorological observatories if Edward Sabine were to continue to study the observations made [see GA's 1858-1-29].
Sends JH some responses to a letter from Edward Sabine on Colonial observatories [see GA's 1858-3-13].
Reacts to JH's suggestions [see JH's 1858-5-[10]] for altering GA's responses [see GA's 1858-5-4] to Edward Sabine's report on magnetic observatories [includes a silly riddle, apparently passed on from Augustus De Morgan].
Provides a more detailed response to Edward Sabine's report on magnetic observatories [see GA's 1858-5-12].
Has looked at the magnetic observations made at the Cape, and comments on their usefulness.
If magnetic observation stations are to be set up and staffed, then personnel should be considered soon.
Supports JH's intentions [see JH's 1858-6-26] and Edward Sabine's proposals about magnetic observations, but displays little faith in the effectiveness of the B.A.A.S.
Is unhappy with one aspect of Edward Sabine's report [see ES's 1858-6-26], specifically the number of days each year when simultaneous observations will be made at all stations.
Indicates GA's intention of being at the Leeds meeting [of the B.A.A.S.].
Thanks JH for his comments on PR's plan for London drainage. Asks another question regarding the system.
Asks for JH's autograph. Aspires to be an astronomer. Was impressed by JH's feeling for humanity at the Leed's Young Men's Christian Institute.
Acknowledges JH's letter and thanks him for it. Praises JH profusely.
