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.
Regrets he will be unable to visit Cork for the B.A.A.S. meeting, but is conscious of the honor of the invitation.
Encloses bill, which JH signed, received from J. C. Stewart. JH and family visited Dover with G. B. Airy's family, where JH witnessed noiseless explosion of 18,000 pounds of powder distributed over 18 acres.
Comments on book on etymology forwarded by Sherwood & Co. [see 1843-5-26].
Discusses deficiencies in astronomical equipment at Cape's observatory, and troubles in observing comets, double stars, and other phenomena. Hopes equipment can be updated.
Completed 'one of the most curious products' of JH's Cape Results: the map and catalog of the 'Nubecula major' region.
Reaches conclusion about Gamma Virginis. States in regard to shape of orbit, 'We are all wrong.' Believes the orbit is less than 150 years. Claims that many errors exist in British measurements made between 1829 and 1834.
Sends JH's 1817 observations; cannot locate any he made in 1811. Tells WS Gamma Virginis measurements will take more time.
Will review all Gamma Virginis observations before revising orbit. Catalogue of major nebulae complete; will work on minor nebulae next.
Is expecting to be summoned to Slough, about repossessing JH's [and William Herschel's] old premises; this will affect JH's availability for a meeting [see GA's 1843-6-24].
Asks GA on behalf of F. W. Bessel, for unreduced positions of a star that FB wishes to examine for annual parallax.
Apologizes for confusion about F. W. Bessel's request [see GA's 1843-6-6], but JH had neglected to check date on FB's letter.
Thanks FB for some papers; raises questions relating to remodelling the constellations of the southern sky.
