VICRAMADITYA AND SALIVAIIANA. 243 



Savan, or natural days, contained in a Calpa, was 

 1,577,9 16,4.30,000 instead of 1,577,917,828,000, as 

 given in the Sihya-Sidd/ianta. 



In other words, the solar sidereal year, instead of 



D D P V 



containing 3^5 15 31 31 24", was estimated to con- 

 n D p V 



tain 365 15 30 I9 30"'; and, therefore, we must mul- 

 tiply 1,577,916,450,000, by 1,972,944,000, and divide 

 by 432,000,000 ; the quotient will be found to agree 

 exactly with the number of days mentioned by 

 Albumazar; that is, it will be 720,634,442,715, 

 without any fraction. 



It is therefore probable, that the true reading of 

 the passage quoted should be, " the Hindus reckon, 

 from the creation to the Cali-yuga (or the flood) 

 720,634,442,715 days; and from the flood to the 

 Hejra, 3725 years." 



It may, farther, with confidence be inferred, that 

 JlL Anquetil du Perrotis conclusion, with respect to 

 the late introduction of the yugas, which are the 

 component parts of the Calpa, into the Hindu astro- 

 nomy, is unfounded ; and that the invention of those 

 periods, and the a}:^lication of them to computations, 

 by the Hindus, must be referred to an antiquity 

 which has not yet been ascertained.
