﻿©F THE HINDUS, 2?I 



The ayanansa added to the sun's longitude in the 

 fibula sphere, gives his distance from the vernal 

 equinox : of the sum take the bhuja ; that is, if ic 

 exceeds three sines, subtract it from six sines ; if it ex- 

 ceeds six sines, subtract six from it; and if it ex- 

 ceeds nine sines, subtract it from twelve. The quan- 

 tity so found will be the sun's distance from the nearest 

 equinoctial point from which is found his declination — 

 as radius is to the paramapacramajya, or sine of the 

 greatest declination 24 , so is the sun's distance from 

 the nearest equinoctial point to the declination sought ; 

 which will agree with the table of declination in pre- 

 sent use, to be found in the tables oi Macaranda, and 

 calculated for the several degrees of the quadrant.. 

 The declination thus determined for one sign, two signs,.. 

 and three signs, is n°43', 20 38', and the greateft. 

 declination, or the angle of inclination of the ecliptic 

 and equator 24 . The co-sines of the same in the Hindu- 

 canon are 3366', 32iy'and 3141'; -ind, as the co-sine of 

 the declination for one sine, is to the co-sine of the 

 greateft declination, so is the sine of 30 to the sine 

 of the right ascension for a point of the ecliptic at that 

 disance from either of the two vishuvas, or equinoctial- 

 points. In this manner is found the right ascension 

 for the twelve signs of the ecliptic, reckoned from the 

 vernal ' equinox ; and also, by the same management 

 of triangles, the ascensional difference and oblique 

 ascension for any latitude : which several particulars* 

 are inserted in the Hhulu books, as in the following 

 table, which is calculated for Bhagalpur, on suppo-

sition that the palabha or equinoctial shadow is 5 30. 

 By the Lagna oiLanca* MadJiyama, or mean Lagna y 

 the Hindus mean those points of the equator which 

 rise respectively with each thirtieth degree of the 

 ecliptic counted from Aries in a right sphere, an- 

 swering to the right ascension in any latitude j by 

 the Lagna of a particular place, the oblique ascension, 

 or the divisions of the equator which rise in succession 

 with each sign in an oblique sphere, and by the chafer 

 the ascensional difference.
