लिप्तास् तत्त्वयमैर् भक्ता *लब्धम् ज्यापिण्डिकम् गताम् । (C लब्धा ज्यापिण्डिका गताः) गतगम्यान्तराभ्यस्तम् विभजेत् तत्त्वलोचनैः॥(२२५)
(Reduce the given degrees &c., to minutes.) Divide the minutes by 225: and the sine (in S'lokas 17—22) corresponding to the quotient is called the gata (the past) sine, (and the next sine is called the gamya to be past sine): multiply (the remainder in the said division) by the difference between the gata and gamya sine and divide the product by 225.

Add the quotient to the sine past: (the sum will be the sine required). This is the Rule for finding the right sines (of the given degrees &c.) In the same way, the versed sines (of the given degrees &c.) can be found.

Subtract the (next less) sine (from the given sine); multiply the remainder by 225 and divide the product by the difference (between the next less and greater sines): add the quotient to the product of 225, and that number (which corresponds to the next less sine); the sum will be (the number of minutes contained in) the arc (required).

There are fourteen degrees (of the concentric) in the periphery of the Manda or first epicycle of the Sun, and thirty-two degrees (in the periphery of the 1st epicycle) of the Moon, when these epicycles are described at the end of an even quadrant (of the concentric or on the Line of the Apsides.) But when they are described at the end of an odd quadrant (of the concentric, or on the diameter of the concentric perpendicular to the Line of the Apsides) the degrees in both are diminished by twenty minutes; (then the degrees in the periphery of the Sun's epicycle=13° 40′ and in that of the Moon's=31° 40′.)

There are 75, 30, 33, 12 and 49, (degrees of the concentric in the peripheries of the first epicycles of Mars, Mercury, Jupiter, Venus and Saturn respectively) at the end of an even quadrant (of the concentric, but) at the end of an odd quadrant, there are 72, 28, 32, 11, 48 (degrees of the concentric.)
