Agrees with JH opinions of Gamma Virginis orbit. Sends JH a drawing by C. P. Smyth of Halley's Comet.
Agrees with JH opinions of Gamma Virginis orbit. Sends JH a drawing by C. P. Smyth of Halley's Comet.
J. R. Hind determined orbit of Mu2 Boötes using JH method.
Sends Gamma Virginis data. Will report Aurora Borealis observations to R.A.S.
Disappointed with format of Nautical Almanac. Arguments over this have caused many hard feeling among R.S.L. members. Details the controversy.
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 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.
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.
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.
Discusses controversy over the discovery of Neptune. Astronomical committee of R.S.L. advised to award U. J. J. Leverrier the Copley Medal.
W. R. Dawes observes sub-division of Saturn's rings. WS continues observing double stars recommended by JH.
Asks JH for description of JH's 'little sweeper' telescope; plans to give a sketch of it in WS's book.
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 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.
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.
Gratitude for [Cape Results]. Feels JH 'let off [James] Dunlop in a softer stile than he deserves.'
