﻿OF THE HINDUS. 279 



The moon's longitude subtracted from the sun's, 

 leaves 5 s 27 34' 17", or 10654 17", which, divided 

 by 720', the minutes in a mean tit' hi, quotes four- 

 teen even tit'his expired, and the fraction, or remain- 

 der 574' 1 7", is the portion expired of the 15th, or 

 purnima tit' hi, which subtracted from 720', leaves 

 145' 43" remaining unexpired of the same; which, 

 divided by the moon's motion per danda from the sun, 

 will give the time remaining unexpired from midnight 

 to the instant of the full moon with as much preci- 

 sion as the Hindu astronomy requires. Deduct the 

 sun's motion 60" 24"' per danda from the moon's 

 740'' 42'", the remainder 680" 8'", is the moon's mo- 

 tion from the sun ; by this divide the part remaining 

 unexpired of the purnima tifhl 145' 43".

therefore 12 dandas, 51 pahs after midnight will be 

 the end of the purnima tit' hi, or instant of opposition 

 of the sun and moon. 



FIFTH OPERATION. 



Having the instant of opposition as above, to find 

 the true longitude and motion of the sun and moon, 

 the latitude of the latter, and the place of the node. 



D. P. 



'Add the mean motion of each for 12 51 to the mean 

 place, found before for the true midnight ; and for the 

 mean places so found, compute again the anomalistic 

 equations. This being but a repetition of operation, 

 the third is unnecessary to be detailed. The several 

 particulars are as follows :
