* Phe right Afgenfion of this Star (independent of the Ann. War.) muft be increafed by 
‘an arithmetical progreffion, the firft term and common difference of which is 1.01, and the 
number of terms will be the years olapfed fince 1789 :—as for example, let it be required te 
findthe Right Afcenfion of the Pole Star, on the rft of January 1800. Then 1./01XT1== 
rx./1t1 the laf term, and 11./11. 441." or = 12."£2== the fum of the extremes ;—then 
W 
=x 11 = 66."66 which is the fum of the progreffion,—then the Annual Variation 
183/.03 X 11 = 2013”,83 = 3333.” this added to os. 12° 3% 7%. 6. will give 
os. 13° 5/ 40.” 39, and thisfum increafed by the fum of the progreflion 1/ 6." 66 will give 
os. 13. 6! 47. 05, forthe mean Right Afcenfion of the Star: but if the Right Afcenfion 
of the Pole Star is required before the beginniag of the year 1689, then the Ann. Var. and 
fum of the progreffion will be deductive.
