to the Pole. Of the stars whose places have been thus determined, 

 believing that their positions may be of considerable use to astrono- 

 mers, Mr. Henderson now communicates a Catalogue, exhibiting 

 their mean positions reduced to the beginning of 1832 (fictitious year 

 of the Astronomical Society's Catalogue). This Catalogue, under 

 the title of " Positions of Stars near the South Pole for the begin- 

 ning of 1832," is given in the "Monthly Notices" of the Society for 

 May. 



Various Observations made at the Cape Observatory, by Mr. Hen- 

 derson, Mr. Meadows, and Mr. Fayrer : viz. observed right ascensions 

 of the moon and stars 1832, April 10 to October 17, inclusive} ob- 

 servations of the moon and stars, made with the mural circle, for the 

 determination of the moon's parallax; 1832, July 20, to January 2, 

 1833, — of Mars and stars, made with the mural circle, for the deter- 

 mination of the parallax of Mars : eclipses of Jupiter's satellite, 1 832, 

 April 12 to October 19; occultations of planets and fixed stars by 

 the moon, 1832, August 10 to October 31 ; and the transit of Mer- 

 cury, May 4 and 5, 1832. 



A paper on the Solar Parallax. By Mr. Shires. 



On the Determination of the true Heights of distant Mountains 

 from their apparent elevations above the sea. By G. Blackburne, B.A. 



The object of this investigation is to furnish a convenient formula 

 for the computation of the terrestrial refraction in terms of the di- 

 stance of the observer from the object, and the apparent elevation ; 

 and secondly, for the computation of the true height of the object 

 itself. 



June 14. — The following communications were read, some of 

 which we shall further notice in our next Number.
