To apply this rule in finding the Vrihafpati year for a given time, as for 

 the commencement of the current year of the caliyug, or when 4892 years 

 of that era were expired, correfpondent with the 10th of 1 aft April* we have 

 the following data.* The revolutions, or mean motion of Jupiter 364220 

 in 4320000 folar years j and the term expired of the call yug 4892 years, 

 which, for the reafon given in Vol. II. page 244, may in this cafe be ufed 

 to fa ve trouble, inftead of the period expired of the Calpa : then, as 4320000

 II. page 275) a correction of bija is here to be applied to Jupiter's mean 

 place at the rate of 8 revolutions in the maha yug fubftractive. But 8 revo- 

 lutions in 4320000 years are as i° to 1500 years j therefore, by a fliorter

 the firft, falls on Dundubhi, which is the 56th of the cycle; and, of this
