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.
Sends letter from Mr. Rüppell, who wishes to get a copy of R.A.S. medal.
Adds clock to telescope, enhancing distance measuring power. Search for Halley's Comet begins. Reports double star data; observes nebulae in JH's Catalogue of Nebulae. R.A.S. location moved to Somerset House. Quarrel between James South and Richard Sheepshanks being arbitrated.
Describes factors that led to C. P. Smyth's appointment to Cape. Uses rock crystal prism for double star observations. Continues observing JH's nebulae with equatorial clock. Approves of proposal for worldwide meteorological observations; will distribute brochures.
R.A.S. making exception in letting J. H. Mädler's chart be removed for JH. Continues observation of Gamma Virginis.
Discusses importance of Gamma Virginis: 'I consider it a grand key to several important physical points.' W. R. Dawes claims to have observed a third Uranian satellite.
Pleased with JH Gamma Virginis observations. 'Lunar affair' disappoints WS. Cycle of Celestial Objects being translated into Italian.
May include JH's position on Neptune discovery in a new edition of Cycle of Celestial Objects. Will review objects catalogued in the volume with refractor.
Has difficulty observing sun spots. Thomas Maclear sends WS information for next year's occultation of Alpha Tauri. Completes rotating roof for personal observatory.
Discusses controversy over the discovery of Neptune. Astronomical committee of R.S.L. advised to award U. J. J. Leverrier the Copley Medal.
Presents JH with R.A.S. medal for Catalogue of Nebulae.
Plans study of Joseph Bianchi's New Sidereal Catalogue. Sends Bianchi excerpt describing double star of Gamma Virginis.
Sends early nineteenth-century astronomical observations. Francis Baily receives £500 from Parliament to enlarge stellar catalogue. Otto Struve's observations of Gamma Virginis agree with JH's.
Thanks JH for a copy of the new edition of Outlines Astr.
Sends Gamma Virginis observations. Devotes time to nautical astronomy; experiments with formulae for calculating occultations. Takes interest in eclipse of Jovian satellites.
Apologizes for controversy at meeting with James South over the transit circle.
