Scheat, in the constellation Pegasus, about 3 degrees to the North ; 

 its altitude on the meridian was about 52 degrees ; the centre of 

 the luminous fluid then passed directly over the star Altair, in the 

 constellation of the Eagle, passing by the stars Delta and Epsilon, 

 in the constellation of Ophiuchi, reaching the western horizon 

 about 8 degrees South of the West. It greatest altitude, 56 degrees, 

 obtained in 25 degrees of azimuth East of the meridian, or the 

 highest point of its centre, was nearly in the direction of South- 

 south-east ; when most brilliant and best defined, its width was from 

 2 to 3 degrees, from which it varied to 8 or 10 degrees during the 

 latter part of the time of its appearance : it finally went off about 

 nine o'clock. It resembled a narrow stratum of white smoke, and 

 appeared to pass through the air with considerable velocity. If 

 this luminous matter was at any very considerable height above the 

 earth's surface, its apparent velocity was much increased by the 

 earth's annual and diurnal motion from West to East, in a contrary 

 direction to its apparent motion." 



ON CERTAIN ERRATA IN DR. MACKAY's TABLES OF VERSED 

 SINES. BY MR. GEORGE INNES. 



To the Editors of the Philosophical Magazine and Annals. 



Gentlemen, — I have lately seen a loose MS. containing errata in 

 Dr. Mackay's Tables of Versed Sines, in a copy of his Treatise on the 

 Longitude, extending from 16° 0' 40" to 44° 29' 10". As I am aware 

 that there are errors in other parts of this table, I suspect that it is 

 only a small portion of the list which I have seen, and that the other 

 part may have dropt out of the book. I would therefore request that 

 any of your correspondents who may be in possession of the other 

 part, will have the goodness to send it for insertion in your valuable 

 Journal.
