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.
Wrote and asked F. L. Chantrey to write to MH. Baby Caroline is fine. Condolences as MH attends to sister Isabella.
Isabella Stewart's death seems imminent. Should JH bring baby Caroline to London for funeral? Mrs. Moorsom reports that Lady Mary Herschel needed help of physician Mr. Fowler. Baby is fine.
About Isabella Stewart's health, MH's toothache, JH's mother's health, and MH's daughter Caroline's good health.
Is trying to help arrange for a cast to be made of Isabella Stewart's face on her death; MH's daughter Caroline is doing very well.
Advises WS on best ways to make a 'darkening glass' for solar observations. Also suggests method for delineating sunspots. Hopes WS will attend Nautical Almanac meeting and support his points. Completes two telescope mirrors and observes Uranian satellites. Asks WS to look for a double star between Beta1 and Beta2 Capricorni.
Will be very pleased to see him and hopes he will spend longer with him. Has just finished a new 20-foot mirror for his telescope. Regarding alterations in the Nautical Almanac.
Gives reason why he wishes to omit the F.R.S. from the title page. Gives layout of entry for the title page. Prints the slips into a book so would like them printed on one side only of the page.
John [Stewart] arrived with news that JH's basket never reached MH. JH will come to London tomorrow. Baby Caroline is at Windsor with grandmother Mary Herschel.
Discusses WS's observations of double stars and method of averaging positional determinations. Believes he has verified the two Uranian satellites observed by William Herschel.
[Responding to SR's 1830-9-6], provides information on James Bradley's observation; also notes a 'striking' anomaly in observation. Mentions study JH is doing on the Castor star system and JH's observations of Uranus's two moons.
Sending books for Wilhelm Struve. Would like to see the latter before he returns to Germany.
About the editing of JH's writings by W. H. Fitton, and about some errands to be done for JH.
[Responding to TH's 1830-9-10], JH notes that John Murray declined to publish an edition of William Herschel's papers. Believes if republished his father's writings should be corrected and annotated, which JH could not at present undertake.
Has not seen the letter in the Herald about the possibility of himself standing for the presidency of the R.S.L. Raises six queries regarding manufactures and other scientific facts.
Declines an opportunity to consult [with JH?].
About the sad state of the R.S.L. under the presidency of Davies Gilbert, and what is to be done to improve it.
Apologizes that JH has been to busy to study James Bradley's observations of double stars sent by SR. Has been busy writing on another subject.
About the pressure on JH to complete his book, Prelim. Discourse, and JH's plans about coming to London.
Cannot attend meeting [concerning the Nautical Almanac]. Makes numerous specific recommendations concerning its format and contents. Raises the theoretical question 'Does sidereal time flow uniformly?'
A note sent with a parcel to be delivered; JH's book is progressing well.
