Questions dates in William Herschel's observations. Wishes JH luck on completing translation of Iliad.
Suggests Moyes Publishing Company to JH. Observes Encke's Comet. Visited by W. R. Hamilton and John Russell.
John Lee has obtained transit circle for Astronomical Society. WS suggests someone other than Thomas Maclear operate it so Maclear has time for occultation project. Details observations of aurora.
Sights bright patch on moon; asks JH to confirm the observation.
Unable to spot Biela's Comet. Outstanding observing conditions allow WS to sight normally difficult objects. Makes suggestions concerning JH's rotating roof plans.
Thanks JH for recommendation of C. P. Smyth. James South returns from Ireland; reports great observing conditions there.
Lunar model will be placed in Somerset House.
Sends observations of the double stars, which JH had suggested.
Reports conflicting observations of Gamma Virginis. Uses JH's method of measuring double star positions.
Sends correction to data for Gamma Virginis. Asks if JH has 'considered the puzzle of Aristarchus [lunar crater]' discussed in WS's Cycle of Celestial Objects.
Finds mistake in JH publication [Outlines Astr.] that assigned discovery of Hyperion to W. R. Dawes and G. P. Bond without crediting William Lassell.
Studies sidereal chromatics. Asks if William Herschel recorded colors of Beta Cygni in a 1779 observation.
Very impressed after meeting W. R. Dawes and discussing double stars with him. Asks JH to send Gamma Virginis observations from Cape.
Awaits copy of JH's Telescope. Problems with by-laws of R.A.S.
Sends JH copy of his work on Mediterranean; answers some of JH's questions.
Double star orbits not ready; R.A.S. waiting for JH's new calculating method. Reads accounts of Biela's Comet. Describes Edinburgh Observatory in detail.
Studies two possible orbits of Gamma Virginis; sends complete descriptions of both, including calculation of the apparent and actual ellipse. The first orbit combines the data of other astronomers.
Pleased that JH has received knighthood. Observes Alpha1 Capricorni in attempts to see a double star. Thanks JH for double star observation outlines; asks for a 'large supply' of them.
Sends micrometer observations of stars suggested by JH.
