The Right Ascensions, in Time, and Polar Distances of 46 prin- 

 cipal Jixed Stars, for the \st of January 1821. 



The zenith distance, or co-altitude, of any of these stars, may 

 readily be obtained, by subtracting the co-latitude of the place 

 from the star's polar distance, if this distance be greater than 

 the 00-latitude; but if less, subtract it from the co-latitude.
