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.
Has received colored tracing from Italy of drawings by Col. Beek. Compares them with what may be done using the Great Pyramid.
Was grateful for the copy of JH's article on the telescope. Sends parcels containing two specimens of 4-ft. specula; comments on these. Weather has been unsuitable for observations.
Has had a paper placed in his hands from an Icelandic Savant regarding drifts from Greenland. Thinks that JH may find this paper useful.
Can JH spare a few minutes one morning as he wishes to show him an invention to overcome seasickness; would like his comments.
Will not detain JH more than half an hour; if his invention is not similar to JH's it will amuse him. Gives his reasons for seasickness. Will call tomorrow.
Since they met yesterday he has thought of a further modification in the apparatus to prevent seasickness and would like JH's opinion.
Has overcome pitch and roll with his inventions. Instrument is quite simple. What is he to do with it now?
Has made a bad sketch of the instrument to prevent seasickness; comments on it.
Many thanks for JH's article on the telescope; will read it with much interest. Has employed an assistant to prepare drawings of the nebula. The six-foot reflector requires repolishing.
Is interested to hear of SN's anti-seasickness invention, especially as JH has just devised a swing-cot for the same purpose.
Please withdraw [?]'s name from ballot until JH can confer with him when [he] comes home on leave next year. Thanks for care that JS is showing to Alexander S. Herschel.
Summary of research on terrestrial magnetism in other countries. Will send paper on magnetic storms to JH.
Sends sample sheets of magnetic reductions from continual observations photographed at Kew. Explains reduction formulas. Will send to JH new paper by ES on lunar diurnal variation. Carlo Matteucci reports interest by new government in Naples in reviving meteorological observatory there.
Asks JH to comment on ES's paper, which will be read to R.S.L. on 10 Jan. Corrects errors in two earlier letters to JH. Will adopt 'Photograms' instead of 'Photographs.'
Sends his certificate for the R.S.L. to JH to sign.
A note with a copy of JH's article on telescopes for the Encyclopaedia Britannica, together with some papers to be forwarded to James Glaisher.
Thanks for declination readings from photograms at Kew. Thinks meteorological observatory on Vesuvius is good idea, but not sure a magnetic one is. Includes two charts of world.
Sends pictures of sun. Thanks JH for sparking his interest in the sun. Wants JH to direct the B.A.A.S.'s use of the Kew telescope to take pictures.
Has tried a number of different fractional projections, some more interesting than others [see GA's 1860-12-7].
Awaits copy of JH's Telescope. Problems with by-laws of R.A.S.
