By comparing the errors given in the preceding 

 table at the different periods, with each other, it 

 will appear, that they were least between seven and 

 eight hundred years ago ; which clearly demon- 

 strates that the Siirija Siddhanta, was written at or 

 near that time. For all astronomical works, whe- 

 ther founded on real or artificial. systems, must ne- 

 cessariU' give the positions of the planets nearer the 

 truth, at, or about the time in which they were 

 originally framed, than at any other distant period 

 whate\'er either before or after. 



With respect to the errors in the places of the 

 planets as computed from the Sarija Siddhanta, they 

 are not to be attributed to incorrect observations;
