IS. The mean longitude of the Sun, Moon, and 

 planets, in the Hindu sphere, at the end of the year 

 4900 of the Call 2/ug, being thus determined, we 

 must now find the quantities of the mean annual mo- 

 tions, that will j;ist give these positions, reckoning 

 from the commencement of the Call i/iig, as an epoch 

 ot assumed mean conjunction. 



14. The length of the Hindu year, according to 

 the Siiryci Siddhdnta, is 365 diiys 15^'"' 31' 31" 24'", 

 in which time the Sun is supposed to make one com- 

 plete revolution in his orbit. The mean motions of 

 the Sun, Moon, and planets, in that space of time by 

 De la Lanj)e's tables, are as follows;

15. These motions being reduced to the Hindu 

 sphere, by deducting the difference between the 

 spheres at the end of one complete Hindu ycaY = 

 68" 40'",26 ; we shall have their respective mean 

 annual motions in the Hindu sphere, as follows :
