Can JH deputize for him at the Astronomical Society meeting?
Further eclipse observations from around the world [see HW's 1820-7-30].
Sends three chronometers set to Blackman St. time. Confirm them by a transit of Arcturus tomorrow, then return them to JS at Blackman St. Gives times for next rocket firings.
William Herschel is glad that JH declined offer for WH to become commissioner of longitude. Hopes JH enjoys visit with James South and family.
Thanks for the kind reception afforded him at Slough. Sends a copy of [J. H.?] Schröder's paper on the discoveries of William Herschel. Also sends some observations of the late solar eclipse made in Holland.
Sir Edward Codrington will take charge of chronometer for Captain Copeland if delivered to Codrington at Portsmouth.
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.
Invites JH to the London Institution to meet Humphry Davy.
Meeting at Dr. George Pearson's on Friday next.
