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.
Thanks for the letter and his interest in the matter. Has written to W. H. Sykes relative to his astronomical qualifications.
Has never seen the great nebula of Andromeda satisfactorily resolved; comments on this and gives some of his observations. Will be going to Brighton and then take his family to London for Easter.
Thanks to JH for the copy of JH's Cape Results.
Would he trouble himself about the address only; all the rest will be arranged for him.
Will be pleased to supply the casts [of the bust of Francis Baily; see M. Grantham's [1849]-1-15]; charge is five guineas each.
Sends details of the progress of erecting the equatorial. William Mann is engaged on the Simon's Bay tide observations. The Madras Observatory post was offered to Mann but he declined it for health reasons. Comments on the affairs of [George Smalley], who is in financial difficulties. Not much news from the Cape. Comments on some of the educational news.
Regarding the work of Yvon Villarceau on double stars. Would like a reference from Sir William Herschel's paper.
Wishes to embody in his reports on atmospheric waves details of JH's work in this field. Would like his comments on his suggested wording. Can E. W. Brayley borrow Karl Kreil's book? Nothing from Madras yet.
Sends the proof of the lithograph from the Daguerreotype for JH's comments and additions.
Examined the nebula of Andromeda the night before last with his three-foot instrument. Comments on his observations and the sketch made by [W. C.?] Bond. Would require several good nights to make a sketch of value.
Has received his letter of the 20th and is anxious to know if E. W. Brayley can borrow Karl Kreil's book.
Encloses some sketches to show some remarkable changes in solar spots. Would he place the observations before the R.A.S. when finished with them.
Expresses appreciation for being elected an associate of the R.A.S.
Finds that some of the pages from the paper JH recently sent him are missing. Please send if he still has them. H. P. Brougham (Baron Brougham and Vaux) does not mean to attack the undulating theory. Regarding solar spots and the surface of the moon.
Shall send a catalogue of double stars observed by [W. S.] Jacob. Gives some information about several measurements to establish standards.
Has just received JH's letter giving details of an interesting auroral phenomenon. Has been experimenting with wire insulates. Henry Lawson has observed streams of red light resembling aurora.
Regarding the 'chilled' casting of a telescope.
Sends sample of photographic lenses ground by JJ. Asks JH for formula of curvature to admit more light.
It is now time that they speak to John Russell (1st Earl Russell) concerning [Francis?] Ronald[s]. Would next Friday suit him?
Regarding the early history of the calendar. Comments on the various versions.
