I. Catalogue of 76 stars. By R. Snow, Esq. 



This catalogue is an experiment towards determining how nearly 

 the results of a small transit may be brought to accord with those of 

 large observatories. The instruments employed were a 20-inch transit, 

 on a cast-iron stand and a brickwork pier, and a sidereal chronome- 

 ter beating half-seconds. When seven wires were not used (which 

 was generally the case) those employed were reduced individually to 

 the mean of the seven by a subsidiary table obtained from 1 transits 

 of Polaris, and 20 of h Urste Minoris. 



Mr. Snow enters into the detail of his method of observing, and 

 the results are as follow. Of the 76 stars, 67 are in the Greenwich 

 catalogue of 1 1 12 stars, of which 5 absolutely agree with the Green- 

 wich observations, 41 differ by less than s , 1, 17 by more than s , 1 

 and less than S ,2, and 4 by more than S ,2 j the greatest difference 

 being S ,26. The plus and minus errors are equally divided, the sum 

 of 3 1 of the first being 2 3 ,95, and of 3 1 of the second, 3 S ,03 ; giving, 

 when signs of errors are taken into account, — S ,0012 as the mean 

 difference of the two catalogues. 



II. Immersion of £ Libra, July 15, 1834,— of e Capricorni, Sep- 

 tember 17, 1834, — and of p Arietis, February 4, 1835, observed at 

 Ashurst. By R. Snow, Esq, 



Hi. Opposition of Vesta, in November 1834, observed at Edin- 

 burgh. By Mr. Henderson. 



IV. Opposition of Jupiter, in November 1834, observed at Edin- 

 burgh- By Mr. Henderson. 



V. Inferior conjunction of Venus, in December 1834, observed at 

 Edinb ur gh- By Mr. Henderson. 



VI. Opposition of Mars, in January 1835, observed at Edinburgh. 

 By Mr. Henderson. 



VII. Observations by the Transit and Mural Circle of Mars and 

 stars in his parallel, made at Paramatta, from October to December 

 1832 Bv M'« Dunlop. Communicated by Sir Thomas Brisbane. 



VIII. Observed Right Ascensions and South Polar Distances of 

 Vesta and stars in her parallel, with the transits of the stars on which 

 the right ascensions depend j observed at Paramatta, in July 1833. 

 By Mr. Dunlop. Communicated by Sir Thomas Brisbane. 



IX Observations of a Comet in 1833, and of another in 1834, 

 observed at Paramatta by Mr. Dunlop ; with Remarks by Mr. Hen- 

 derson, in a letter to Sir Thomas Brisbane. Communicated by Sir 

 Thomas Brisbane. 



The comet of 1833 was very small, and was observed from Sep- 

 tember 30 to October 16. That of 1834 was observed from March
