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.
Is grateful to JH for proposing EL as a candidate for the R.S.L. Has been experimenting with ozone; comments on his observations.
A daughter of Thomas Maclear is to spend several days with JH and his family before returning to the Cape.
Sending him [Balfour] Stewart's certificate in the hopes that he will add his name to it. Hopes to show him his experiments when he has the time.
Estimates seven weeks and £10 to compute JH's nebulae data. Suggests JH use new 'Skeleton Form.'
Has been considering how to incorporate JH's suggestions regarding the insertion of the Julian dates in the Nautical Almanac. Would like his views. Quotes extracts from a letter of U. J. J. Leverrier.
On a static measure for gravity.
Is going to Kashmir for a geological survey. Wonders if while he is there he can carry out any meteorological research.
Returned JH's 'original sheets of nebulae.' Kept sheets of calculations. Will write about money accounts later. Lord Palmerston's communication about Thomas Maclear's pension.
Many years ago he read a paper to the Royal Scottish Society of Arts on the merits of JH's telescope compared with that of William Parsons (3rd Earl of Rosse); this paper has never been printed. Gives details of his own optical work.
Hears that his chance of success at the R.S.L. is good. [John?] Lee will forward the certificate to JH for presentation to the R.S.L.
Glad that JH approves introducing Julian dates. Notes their use in American lunar tables. Positions of three new nebulae.
JH will be pleased with Mr. de Souza's and [Charles] Smallwood's letters. American and Havana instruments were dispatched. [Hermann] Schlagintweit has made interesting magnetic survey of India.
Is grateful for JH's letter and pamphlet. Worked on portraiture before Mr. Baird and assisted him later. Outlines the various lenses he used and made for other people. Is pleased JH has a good opinion of the work of [W. B.?] Rogers. Is he familiar with the works of [Thomas?] Dicks in astronomy?
Describes procedures, apparatus, and calculations for determining the static gravity of the earth. Thanks JH for some of his writings, and comments that JH, like Newton, has discovered the mind of the Creator and passed this on to humanity.
Asks JH's help in efforts to publish a complete edition of writings of physicist Augustin Fresnel.
Has now had ample time in which to study JH's pamphlet. Comments on various points. Has constructed a 4 1/2" aperture achromatic telescope, but the buyer went bankrupt. Would welcome assistance from JH.
Will present to R.S.L. Council JH's application for money for reducing JH's catalogue of nebulae.
Thanks for his letter, which he will communicate to the Lit. and Phil. Soc. Regarding the views of William Hopkins. JH's theories regarding the effects of the sun spots are similar to a recent Frenchman's.
Board of Guardians have invited the Parish to consider the proposed new Assessment Bill. Sends a copy and would like JH's comments.
Sending two very singular empirical laws relating to the solar system and inviting JH's comments on them.
