object was to try " with how little expense and trouble, compared 

 with, that which is encountered in the use of a circular instrument, 

 a very fair latitude may be obtained." 



Of twenty different observations, two were rejected as evidently 

 affected by errors of level ; the remaining eighteen gave results, of 

 which the extremes differed by six seconds of space. The mean 

 was 5 1° 15' 56", being 2" less than that obtained from the Ordnance 

 map by Lieut. Murpiiy. The latitude and longitude, from the lat- 

 ter, are 



51° 15' 58" N. and 0" 1"' 9^- 3 W. 



IV. Observations of occultations made at Ashurst, by Mr. Snow. 

 These are, April 6, 1835, immersion of k Geminorum; April 12, 



immersion of Saturn's centre; April 1(5, emersion of 6 Ophiuchi j 

 August 14, immersion ofw Arietis. 



V. Observations made as Trinity College, Cambridge, by Mr. 

 Rothman, 



These are Oct. 7, 183-4, emersion of 9 Ophiuchi ; and several im- 

 mersions and emersions of Jupiter s satellites, in October and De- 

 cember, 1835. 



VI. Observations made at Fort Charles, Port Royal, Jamaica, by 

 Captain Sir Everard Home, Bart., and Mr. Drury, of His Majesty's 

 ship Racehorse. Communicated by the Rev. G. Fisher. 



These consist of observations of the end of the solar eclipse of 

 Nov. 30, 1834, and of eclipses of J2<pi<er's satellites. Mr. Fisher has 

 annexed an observation of his own of the occultation of Saturn, on 

 April 12, 1835. 



VIL Transits of the moon and stars observed at Argos, at the 

 observatory of General Gordon. By Mr. James Robertson. 



These observations were made in the last quarter of ISS^ and the 

 first of 1835. 



The longitude of the Acropolis at Argos has been deduced in the 

 French survey of the Morea. According to the estimation of the 

 relative positions of the Acropolis and Gen. Gordon's Observatory, 

 the longitude of the latter, as determined from the moon culminating 

 stars, exceeds that obtained from the survey by 5' 3G"'4 of space. 

 The observatory is a small low building, in the garden of Gen. Gordon 

 at Argos ; the transit instrument is by Jones, and is firmly fixed on a 

 stone pillar ; the clock is by Lepaute, has a mercurial pendulum, and 

 gees tolerably well ; the telescope with which the. satellites oi Jupiter 

 were observed is by Harris, of 3| feet focal length, and the power 

 used was about 130. 



VIII, Various observations, made at the Royal Observatory, 

 Edinburgh. By Professor Henderson. 



These consist of occultations, and of eclipses of Jupiter's satellites, 

 in 1834-35 ; and observations of Pallas, Ceres, and Saturn, at tlieir 

 last oppositions. 



IX. Extract of a letter from Dr. Pearson to Francis Baily, Esq., 

 containing an observation of Halley's Comet -. 



" On the !9th of October I liad an opportunity of directing a 

 tolescojie to the Comet, as it passed k Ophiuchi, to the north side of
