218 ON THE HINDU 



Now, taking the nearest entire numbers (ex- 

 cept for Mars, w^hich in order to increase its mo- 

 tion a little, take the next greater number), and 

 we shall have 



Tt . .' By the Surya 



Irom computation. ' Siddhania. 



Sun, 1080000 Kevolut. lOSOOOO Revolut. 



The numbers from computation being the same 

 as in the Surijci Siddhmta^ the mean motions and 

 positions of the planets, to be from thence de- 

 duced, must necessarily be the same also. 



If the numbers above found, be multiphed by 

 4, we shall have the revolutions of the planets in 

 a Mahd Fug, or 4320000 years : and if the revo- 

 lutions in a Afdha Vug, be multiphed by 1000, we 

 get the revolutions in a Calpa. 



The mode of applying the above numbers to 

 practice, must be sufficiently obvious from the 

 manner in "which they are determined, as well as 

 from the rule laid down at page 211. I shall, 

 however, add here a few examples. 



1st. Let it be required to determine the Moon's 

 mean longitude, at the end of the year 4100 of 

 the Call Vug. —
