nually ; and not 54", as found in some Hindu books. 

 Hence it follows, that if the motion of the aphelion 

 of a planet, was exactly 58" 40'" 15" 3b% in the Eu- 

 ropean sphere, it would have none in that of the 

 Hindus; but would be considered as fixed. And, 

 if the motion was less, then it would be retrograde ; 

 as is the case with the aphelia of Mercury, Venus, 

 and Jupiter. 



33. From the motions above determined (§ 3l), 

 we obtain the following revolutions ofthe aphelia and 

 nodes in a Calpa, requisite to give their positions by 

 direct computation. 



These numbers differ widely from those given in the 

 Suryd Siddhdnta (§ 26), owing to the slow motions 

 assigned to the apsides and nodes, in that work. 



34. The revolutions of the apsides and nodes in 

 a Calpa, being thus ascertained, the following ex- 

 amples will shew their applications and use. 



Example. Let it be required to determine by 

 computation, the longitudes of the Sun's apogee. 

 Moon's apogee, and the aphelion of Jupiter, in the 

 Hindu sphere, at the end of the 4^v00of the Caliyug.
