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.
Unable to give in a letter the practical geometrical results he has worked out from the laws of the king's chamber of the Great Pyramid. It would grace a history of Egyptian astronomy.
Thanks for his letter. Any astronomical observations can be recorded on a plane or spherical surface. 108 equal cubes will exactly fill the coffer in the king's chamber of the Great Pyramid.
Outlining a method for making star maps with a pyramid.
Encloses [a diagram] of the transverse section of the entrance of the Great Pyramid, with details of the travelling platform for making observations.
Has received colored tracing from Italy of drawings by Col. Beek. Compares them with what may be done using the Great Pyramid.
Sending a printed circular on his proposed change in the currency.
Pointing out an error by JH in assigning the authorship of a weather table to Sir William Herschel.
Sends a lithograph of the 4-ft. aperture equatorial. Has made no observations with it yet. Had difficulty with the surface of the speculum. Comments on the drawing and on the use of the instrument. Cannot recollect seeing any of the irregularities pointed out by JH in his letter.
Pointing out the reasons for some apparent discrepancies in the drawing of his telescope. The drawing was hurriedly done by his daughter.
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.
Is grateful for JH's kind invitation to Collingwood, but regrets he cannot find time to come as he sails on the day after tomorrow and has much business to fit in before then.
Has experienced an extraordinary meteorological year and been kept busy observing all the changes. Is to submit another certificate to the R.S.L. and would be pleased if JH would sign it.
Thanks for signing his certificate for the R.S.L. Has promise of support from members of Council. Has just contrived a new ozone box; gives details. Carrying out observations with underground thermometers.
Is giving a dinner for the Hawkhurst Rifle Volunteers and would welcome JH's presence.
Has today dispatched a parcel to JH containing a copy of a Chinese translation of JH's work on astronomy; thinks this work will be of great service to the Chinese.
Grateful for JH's congratulations. News of the education of his own sons. Pleased to hear of Warren de La Rue's success with photographing the pink projections during the total darkness. Recent astronomical observations. News of the Cape Electric Telegraph. Mr. Wollaston (a nephew of W. H. Wollaston) is about to make a survey for the telegraph wire. Gives details of the electric clock in connection with the transit circle.
John Murray has shown him JH's note. Is pleased to have an article from JH for the Quarterly Review on his observations. Hopes he will show the influence of the moon on the weather.
Thanks for his letter. Will look forward to receiving his article in time for the July issue of the Quarterly Review.
Has recently read in the papers JH's correspondence concerning the weather. Would like an article on this subject from JH for the Quarterly Review. Comments on the influence of the moon on the weather.
Has had a paper placed in his hands from an Icelandic Savant regarding drifts from Greenland. Thinks that JH may find this paper useful.
