Precept 1.
The Declination of the Sun or other Planet is found by the signe in the head or foot, and the degree on the right side, if the signe be in the foot, or on the left side if it be in the head: for the common angle gives the Decli∣nation sought, if you have respect, to your Planets proper latitude, and the proper part proportional.
For Example: Suppose the Moon were in 19 degrees 56 parts of Leo, and her declination were required, having North latitude 3 degrees. Her Declination in that latitude, in 19 degrees of Leo will be found 18. 02
| In 20 degrees it is | 17. 70 | |
| There difference is | 0. 32 | |
| Now then if one degree give | 0. 32 | 1. 5051499▪ |
| What shall | 0. 56 | 1. 7481880 |
| They give 18 ferè | 1. 2533379 |
Which being subtracted from 18. 02 because the Declination doth de∣crease, the Moons Declination will be found to be 17. 84
