COMPUTATION OF THE ECLIPSE. 



Let it be premised that the position of the sun, 

 moon, and nodes, by calculation, will on the first of 

 next Vaisacli be as here represented in the Hindu 

 manner, excepting the characters of the signs. 



By inspection of the figure, and by considering 

 the motion of the sun, moon, and nodes, it appears 

 that, when the sun comes to the sign Tula, Libra, 

 corresponding with the month of Cartic, the descend- 

 ing node will have gone back to Aries ; and that con- 

 sequently a lunar eclipse may be expected to happen 

 at the end of the purnima tifhi, or time of full moon, 

 in that month.
