It was too cloudy for any worthwhile observations to be made during the recent eclipse. Looking forward to the publication of JH's work. Outlines his own recent and projected work. Thomas Brisbane observed the eclipse at Cork.

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 extremely sorry to hear the news of the death of William Herschel. Regarding F. W. Bessel's polar distances in relation to his own, and possible reasons for their difference. Has been working on the Greenwich observations.
Has just received his letter and Struve's observations. Comments on these and those of F. W. Bessel.
Mislaid the copy of one of JB's mss. and would be grateful if he knows of its whereabouts. In the course of his travels in Europe he has seen some astronomical instruments, which will in time surpass any British made ones and especially those of G. B. Amici and Josef Fraunhofer.
Has only fragments of the paper for which JH inquires; original was left for W. H. Wollaston to amend. Thanks for congratulations on the award of the Copley Medal. Was interested to hear about the new German astronomical instruments.
Notes and comparisons for their recent observations of stars. Was interested in the account of Henry Kater's collimator and hopes it will be adapted for Greenwich.
Thanks for his valuable communications. His theory regarding the method of determining the difference of parallax is ingenious. Regarding the difference in observations of certain stars between Dublin and Greenwich. Returns G. A. A. Plana's letter and comments on this. Has not yet printed his paper on fixed stars.
