168 REMARKS on the 



is fubject to great difturbances, from the action of Saturn, 

 which M. de la Lande does not profefs to have taken into 

 account, we will be inclined to appeal once more to M. DE la 

 Grange's formulas, before we pafs fentence againfl the Indian 

 aitronomy *. 



From one of thefe formulas, we find, that the true place of the 

 aphelion of Jupiter, at the time above mentioned, was y, 26% 

 50', 4c", which is but 10', 40", different from the tables of 

 Chrifnabouram. The French and Indian tables are therefore 

 both of them exact, and only differ becaufe they are adapted 

 to ages near five thoufand years diftant from one another. 



41. The equation of Saturn's centre is an inftance of the 

 fame kind. That equation, at prefent, is, according to M. de 

 la Lande, 6°, 23', 19" ; and hence, by means of one of the 

 formulas above mentioned, M. Bailly calculates, that, 3102 

 years before Christ, it was 7 , 41', 22" f. The tables of the 

 Brahmins make it 7 , 39', 44", which is lefs only by 1', 38", 

 than the preceding equation, though greater than that of the 

 prefent century by i°, 16', 25". 



42. M. Bailly remarks, that the equations for the other 

 planets are not given with equal accuracy, and afford no more 

 fuch inftances as the former. But it is curious to obferve, that 

 new refearches into the effects, of gravitation, have difcovered 

 new coincidences of the fame kind ; and that the two great 

 geometers, who have fhared between them the glory of per- 

 fecting the theory of dijlurbing forces^ have each contributed his 

 part to eftablifh the antiquity of the Indian aftronomy. Since 

 the publication of M. Bailly's work, two other inftances of 

 an exact agreement, between the elements of thefe tables, and 

 the conclufions deduced from the theory of gravity, have been 

 obferved, and communicated to him by M. de la Place, in a 

 letter, inferted in the Journal des Savans.
