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.
Asks JH to write an abstract of the discourse JH presented to R.A.S. Moon model is on display at R.A.S.
Asks JH's advice on the purchase of the lunar model. Anxious to see JH's new method of calculating double star orbits.
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.
Receives report on poor state of Paramatta Observatory. Encloses letter from Thomas Brisbane, who believes James Dunlop should be removed from his post of authority there.
Sends copy of James Graham's letter concerning transfer of Paramatta Observatory to government authority. Thanks JH for advice on the matter. Discusses methods of magnitude estimation.
Sends copy of J. R. Hind's observations of Gamma Virginis; believes they are 'too slow.' Also sends report of the Charter Committee of the R.S.L. Believes R.S.L. not selective enough. Has difficultly using JH's method of magnitude determination.
Encloses copy of 29 July 1846 letter from G. B. Airy, who refuses to act on any further recommendations from Board of Visitors so long as James South is member of Board. Insinuations by South in R. H. Inglis's motion before House of Commons are deemed malevolent by Airy, who no longer considers South competent to guide scientific inquiry.
Discusses magnitude determination. Refers to incident in which one of WS's sons will be removed from his position but not given poor references. W. S. Jacob sends double star measurements.
Discusses controversy over the discovery of Neptune. Astronomical committee of R.S.L. advised to award U. J. J. Leverrier the Copley Medal.
Lunar model will be placed in Somerset House.
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.
Sends angular results from various astronomers using similar epoches.
Gratitude for [Cape Results]. Feels JH 'let off [James] Dunlop in a softer stile than he deserves.'
Compiles published work, unpublished work, and lectures; asks JH to proof the compilation. Discusses meetings of R.S.L. concerning charter by-laws.
Discusses the site of Cold Harbor. Visits the small personal observatory of J. G. Barclay, who WS thinks will produce good work.
