 four sines (in a quadrant of a circle whose radius is 3438). These are as follows.

to. 225, 449, 671, 890, 1105, 1315, 1520, 1719, 1910, 2093, 2267, 2431, 2585, 2728, 2859, 2978, 3084, 3177, 3256, 3321, 3372, 3409, 3431, 3438. Subtract these sines separately from the Radius 3438 in the inverse order, the remainders will be the versed sines (for every 3$3⁄4$°).

to. There are 7, 29, 66, 117, 182, 261, 354, 460, 579, 710, 853, 1007, 1171, 1315, 1528, 1719, 1918, 2123, 2333, 2548, 2767, 2989, 3213, 3438, versed sines (in a quadrant).

. The sine of the (mean) greatest declination, (of each of the planets)=1307 (the sine of 24°).

Multiply the sine (of the longitude of a planet) by the said sine 1307; divide product by the radius 3438; find the arc whose sine is equal to the quotient. This arc is the (mean ) declination (of the planet required).

. Subtract the place of the planet from those of the and : and the remainders are the . From the determine the quadrant (in which the Kendra ends,) and the sines of the  and (of the ).

. The sine of the (of the arc which terminates) in an odd quadrant (i. e. 1st and 3rd,) is the sine of that part of
