﻿*3^ ON THE ASTRONOMICAL COMPUTATIONS 



*' Why the Munis, who certainly knew, did not 

 " give the particulate of tho :ions, may seem 



accountable, when the men Aryabhatta^ Brah- 



u magufta, and others have determined them. The 



wa?, that chose del are not in them- 



" selves uniform ; and to state their variations would 



u have been endless. It was therefore thought better, 



rcxami should be made, 



u and due corrections of the Bija introduced. A 

 " Ganita Sattra, whose rules are demonstrable, is 

 " true; and when conjunctions, oppositions, and 

 u other planetary phenomena, calculated by such 

 11 Sastras, arc found not to agree with observation, 

 " a proportionable Bija may be introduced without 

 " any derogation from their credit. It was therefore 

 " necessary, that this Sastra (the Surya Siddhanta) 

 riled in each Yug, and that other 

 " Sastra should be composed by the Mums. 



" The original Sutra then appears to be the Surya 

 " Siddhanta ; the second, the Brahma Siddhanta ; the 

 " third, the Paulastja Siddhanta ; the fourth, the Soma 

 " Siddhanta:' 



In the ' g table are given the periodical revo- 



lutions of th< , their nodes and apsides, accord- 



to the Surya Siddhanta. The correction', of Bija 

 at present u: contained in one column *, and 



the inclination of their orbits to the ecliptic in an- 

 'i be obliquity of the ecliptic is inserted ac-
