Gf S i xt v Years, V*$? 



The numbers 22 and 1875 ufed in this computation are evidently derived 

 from the planetary periods, as given by A'ryabhatta, which according 

 to^T-ARA'HAMiHiRA are, of Jupiter ; 564224 mean revolutions in 4^0000 

 fokr years : but 364224 revolutions o^ Jupiter contain 4370688 of his 

 years, which exceed the correfpondent folar years 4320000 by 50688, and 

 thofe two numbers reduced to their loweft terms are 1875 anc ^ 22 * or ? * n 

 1875 folar years, there is an excefs of 22 Vribafpati years ; and hence the 

 ufe of thofe numbers is obvious. The additive number 4892, by the Hindu 

 aftronomers termed cfhepa, adjufts the computation to the commencement of 

 the era Jdca y which began when the 3179th year expired of the ■ cali yug, ■ 

 and it mows ihat 2 years, 3 months, and 13 days were then expired of the 

 current cycle of Jupiter, or 3 m nths and 13 days of the year Sucla, which 

 is the third of that cycle; A computation by the Surya Siddbdnta for the 

 fame period,' with a correction of bija, as in the foregoing example, makes 

 2 months, 9 days, 56 dandas, and \<l pdas to ha-ve^been elapfed of that 

 year, and that confequently there were 57 years, 9 months, 20 days, 3 

 dandas, and 12 pains then wanting to complete the cycle, .inftead of 43 , 

 years, as it is ftated in the PhilofophLal Tranfa&ions j and, by the fame 

 rule, the yeax of Christ 1784 correfponded-wkh the 48th and 4,9th of the 

 cycle, or Auanda and Rac/hafa, ■ 



This mode of computation difagrees with the date of a grant of land ; 

 mentioned in Vol. I. page 363 of the Aiiitick Refearthes ; for >fica 939 l 

 muft have ended in the 3d month of the 53d year of ■■ the Vribafpati cycle 1 

 but, as the grant in queftion appears to have been made iivthe vicinity of < 

 Bombay, the difference may be accounted for in a manner, that will equally 

 explain the difagreement noticed by Mr. Marsden between his authori- • 

 Sies and the* Banares almanack. We learn from Vara'hamiiura's com-
