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.
[Form letter] Schedule of meetings for Institution of Civil Engineers. As honorary member, JH is invited to attend.
Is grateful for his letter and will study the memoirs to which he refers. The Editor would also like a photograph; can JH oblige?
JH is 'shaky & feeble.' Pleased with biography of ED's brother Thomas. JH's son John and bride departed today for India. Deaths of JH's contemporaries. Describes Constance Herschel's whooping cough.
Writes to inquire as to the exact definition of the gallon and the pound, and the circumstances under which the appropriate measures would be made.
Believes Michael Faraday's boro-silicate of lead has not been used for telescopes, but JH and others have tried using it for other optical purposes. Describes method for producing veinless flint glass.
Provides JH with best definition that GA has available for the gallon [see JH's 1867-11-3], noting that methods for establishing standards are revised, even if the standards supposedly are not.
Plans for refracting telescope TW is constructing. Diagrams and questions about lens construction.
Feels that he has been quoted out of context, making it appear that JH favors the introduction of the metric system in India. This being not the case, JH then proceeds to show how the British system of measures is related to terrestrial measurements, especially the length of the earth's polar axis. In so doing, JH argues for the greater accuracy in the definition of the British units, as compared to the metric.
Has nothing of Mendelsohn to send to JW. Has R.S.L. letters, but JH does not want to part with them.
Offers advice to president of committee for adoption of uniform system of weights and measures for India.
Soliciting articles for People's Magazine.
Sending details of his theory on meteorology and cometography and inviting JH's comments.
Sends JH a copy of 'Enoch.' Thanks JH for his helpful criticisms.
About some instruments to be taken to India by JH's son John.
Does not know if equipment from R.S.L. reached JH's son John at Southampton [see GS's 1867-11-18].
Please transmit enclosed recommendations by JH to Richard Strachey or other members of committee to establish uniform system of weights and measures for India.
News of the forthcoming marriage of his daughter. Everyone seems to be mad on making ice.
Impressed by JH's argument against French metric system. Will forward JH's letter to Richard Strachey or, if Strachey is in Abyssinia, to committee for weights and measures in India.
Describes a method JH devised of producing 'autographic representations of fungi on glass.'
Reports his opposition, shared by JH, to Britain and India adopting the metric system. Discusses WH's wife, Emma, WH's brother John, a coming solar eclipse, and a theory of gravity.
