The annual Equation of the mean Motion of the Sun depends on the Eccentricity of the Earth’s Orbit; and is greatest when it is 1 Degree 11’.
The greatest annual Equation of the Moon’s mean Motion is 11’, 40”. of its Apogee 2° 4’, and of its Node 9’, 30”. See NODE, etc.
These four annual Equations are always proportionable; so that when any of them is at the greatest, the three others are also greatest.
