81. From the revolutions of the Sun, Moon, and 

 planets, &c. in ^Calpa according to Brohma Gupta, 

 (§ 21), we obtain the following mean annual mo- 

 tions : 



which motions being reckoned from the commence- 

 ment of the Calpa of Brohmay gave the positions of 

 Sun, Moon and planets, with those of the Moon's 

 apogee and node in the time of the author of the 

 system, as near as he could determine them by ob- 

 servation. This Calpa of Brohma Gupta, is made 

 to commence with Sunday at the instant of Sun-rise 

 on the meridian of Lanka. 



82. The number of mean solar days assigned to 

 this Calpa/is 1577916450000: And the length of the 

 year therefore =HI|i^l^= 395°^ 15^°- 30' 22" 30'"; 

 hence we have the following mean motions of the 

 bun. Moon and planets, &c. from De la Lande's 

 tables, in that space of time.
