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 interpolated the hourly tidal observations for Simon's Bay.
Describes in detail efforts, only partially successful, made by Thomas Maclear and JH to record tidal data at Simon's Bay and Table Bay. Gives some interpretation of the data.
Busy interpolating the Simon's Bay tidal series; JH then intends to study Table Bay and to compare the results. Asked William Whewell to back an application to the British Admiralty for a tide clock to be erected at Simon's Bay as a permanent tide station.
Sends TM some tide observations, and some calculations done on them.
Glad the government has recognized Mrs. Somerville's work. Discusses the hostility toward natives at the Cape and criticizes actions of colonists. Astronomical observing conditions at Cape are very good.
Kaffirs dispossessed by colonists. Condemns 'Colonial insolence.' Editor John Fairbairn, detested by colonists, exposed this in South African Commercial Advertiser.
Reports on efforts made in June 1835 by JH and Thomas Maclear to have tidal observations made at Simon's Bay and Table Bay. Reports briefly on JH's astronomical observations. Describes increasing tensions with the Caffers [Kaffirs] in the Cape region.
Describes his comparison of the tidal series at Simon's Bay and Table Bay. Sending his barometer to TM.
Reports having read the record JH sent of [tidal] observations and comments on it.
Sending some observations of double stars. Has had some of the sheets of the Brisbane Catalogue. His recent observations. Domestic affairs in the Cape of Good Hope.
Believes that TM is the first to see the return of Halley's Comet [see TM's 1835-9-1].
Comments on CW's work on light and on the velocity of electricity. JH's ruminations lead him to the idea of motion pictures.
Sends information about where to look for Encke's comet.
Congratulates GA on being honored by H. M. Government [GA was offered a knighthood, which he declined], and of being appointed Astronomer Royal, and further tells GA about some of JH's observations, and the instruments in use [letter finished 11 Oct.].
Has not had any success in finding comets.
JH is chagrined to note that he forgot to observe the equinox, after having impressed on any and all the need to do so.
Found Encke's Comet the night before last. Has not had a chance to see Halley's Comet. Will JH come to the Observatory? There are no fleas.
Has received the letters and parcels safely. Is starting reducing his sweeps. Observations in Dublin Observatory. Comments on the various functions of observatories. News of scientific events at the Cape and various expeditions in progress.
Is glad JH has given his opinion to Francis Beaufort on the subject of observations of the first class. Encke's comet is invisible in the 14-ft. within the range of 10 degrees. Last two nights were very favorable. Has seen Encke's comet three times, and it appears just as he saw it in England.
C. P. Smyth has arrived. Remarks on the Brisbane Catalogue. Thanks for his meteorological observations. His own meteorological observations. Affairs in the Cape.
