" From the 138 observations made with both circles, 



Parallax = &96. Weight 77*55 observations. 

 Coefficient of Aberration = 20*48. ... 72*44 

 " From the 112 observations made with the new circle, 



Parallax = 6*93. Weight 72*99 observations. 

 Coefficient of Aberration == 20*52. ... 66*27 



" If the coefficient of aberration be assumed = 20"*36, as in the 

 Astronomical Society's Catalogue, then, from all the observations 

 with both circles, parallax = 0"*98, the separate results for the two 

 stars being 0"*95 and 1"*00; and, from all the observations with the 

 new circle, parallax = 0"*99, the separate results being 0"*98 and 

 0"*99. 



" I believe that the observations are still continued to be made at 

 the Cape ; and I will write to Mr. Maclear immediately, requesting 

 him to send the additional observations. 



" The two stars appear to be approaching each other, the dif- 

 ference of declination being in 1826 = 18", in 1833 = 15", and in 

 1840 ss 11". When all the observations are collected, an attempt 

 may be made to determine the orbits, and thence the masses of the 

 stars. 



" I will as early as possible prepare a detailed memoir on the 

 subject, and transmit it to the Admiralty for presentation to the 

 Astronomical Society. — I am, &c. " T. Henuekson." 



III. Positions of 78 Fixed Stars contained in the A. S. C, repre- 

 sented by Mr. Baily as not determined with sufficient accuracy, de- 

 duced from Observations made with the Meridian Circle of the Ob- 

 servatory of Kremsmunster. By M. Roller, Director of the Obser- 

 vatory. 



IV. Observations of Falling Stars made at Hereford on the night 

 of Nov. 12, 1841. By Henry Lawson, Esq. 



Three observers were employed in watching for these phenomena, 

 from seven o'clock in the evening till half-past four o'clock of the 

 following morning, each taking a distinct portion of the heavens. 

 The whole number observed was 79, and the greatest number ob- 

 served in any one hour was 20, between the hours of three and four 

 in the morning. The result the author considers to be so far satis- 

 factory, that it tends to confirm the fact of the appearance, at about 

 this period, of a greater number of meteors than usual. 



V. A List of Falling Stars observed Nov. 12, 1841, at St. Helena. 

 By J. H. Lefroy, Esq., R.A., Director of the Magnetic Observatory at 

 Longwood. 



The whole number observed was 102, between the hours of eight 

 in the evening and five of the following morning. The Greenwich 

 mean solar time of the appearance of each is noted to the nearest 

 second, and the place of its appearance as referred to the bright stars 

 nearest it. The direction of the motion of each is also given, with 

 remarks on its appearance, rapidity, and other circumstances con- 

 nected with the phenomenon.
