Then say, as 43 20000000 years to the number of 

 revolutions in that cycle, so is the time expired to the 

 longitude.

 but the motion of Jupiter's aphelion being retrograde 

 we must deduct this longitude from twelve signs; 

 and we shall have, 5s. 20' i4' 41" &c. the longi- 

 tude required. 



Again, let the longitude of the Moon's ascending 

 node, at the end of the year 49OO of the Call yug be 

 required.

LENGTH OF THE HINDU YEAR. 



35. Hitherto I have supposed the length of 

 the Hindu year to be 365'^ Id'" 31' 31" 24'", the 

 same as in the Sarya Siddlianta ; and all the preced- 

 ing calculations respecting the motions of the planets, 

 &c. are made on that supposition. It is, however, 

 to be observed, that when a Hindu astronomer forms 

 a new system conformably to the positions of the 

 planets, &c. in his time, he must likewise deter-
