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.
Reports on location of a planetary nebula. Expresses thanks for book by [Robert] Woodhouse.
Some comments about constant error in TM's observations.
Much obliged for JH looking over the observations. Comments on these and the accuracy of the Cape circle and mural circle. Will send his observations on Crucis.
Encloses the Brisbane observations. Appears to be a discrepancy in some of the stars.
Has arranged with Lady Herschel for Sir John to spend a night at the Observatory. Come early; then he can reverse the transit instrument. Is not satisfied with the performance of the transit clock. Intends to clean it. Is ready to adopt JH's suggestions for measuring the tides. Curious that JH and [T. G.?] Taylor should suggest similar plans for measuring the divisions of a mural circle.
About the difficulty of measuring high and low tide with the instruments available to TM; offers the design of an instrument that would measure the mid-point between high and low tides.
Has received letters and books from England. Leave of absence of William Meadows and nomination of Piazzi Smyth. Is preparing a packet of observations for England; has JH anything to send?
Acknowledges Lady Herschel's two notes and will communicate with her in the morning. Encloses the note of Mrs. Smyth [wife of W. H. Smyth?]. Hears that Dr. [John] Lee has been contesting Aylesbury, without success. Estimates for stable have been cut out.
Excited about JH's observations, and has shown them to several people.
Last night was a splendid night for observing. Will be pleased to place the barometer at Captain Richard Wolfe's disposal. Eclipse was interesting. Will call if he goes to Simon's Bay.
Has received some papers and newspapers. Four parcels are on their way to JH via H.M.S. Rattlesnake. Encloses a letter from William Wallace regarding the Edinburgh Observatory.
Sends his two mountain barometers; comments on them. Method of interpolating the clock errors graphically answers well.
William Whewell asked JH to compare their June tidal observations with those of the British Admiralty; JH will urge John Deas Thompson to be extra precise in his findings.
Captain John Stevens was at the Observatory yesterday and wishes to superintend the tidal observations himself. TM intends to make the observations personally, or with the assistance of T. W. Bowler. The lunar eclipse was uninteresting. Has had copies of G. B. Airy's papers; they are excellent.
Has received the box from H.M.S. Rattlesnake and lists the parcels for JH. T. W. Bowler commenced the tidal observations yesterday. Outlines the method used. Was beset by dogs on the way home. Expects to hear from the first ship of an Assistant.
Encloses a copy of the hourly observations. Comments on the tides of Table Bay.
Made a 'mess' of the tidal observation and meteorological observations that he took earlier in the week.
Attempting to correct the faulty tidal and meteorological observations that JH made earlier in the week.
Sent the barometric readings with Mr. Curnan's paper. Comments on the tidal observations. Send the tide book. William Lamb (2nd Viscount Melbourne) is reinstated.
Urges JH to observe Ceres. Describes TM's observations of it.
