Part 32

The first, second, third, and fourth Tables may be continued, by means of the sixth, to any length of time: for, by adding 12 Lunations to the mean time of the New or Full Moon which happens next after the 11th day of _March_, and then, casting out 365 days in common years, and 366 days in leap-years, we have the mean time of New or Full Moon in _March_ the following year. But when the mean New or Full Moon happens on or before the 11th of _March_, there must be 13 Lunations added to carry it to _March_ again. The Anomalies, Sun’s distance from the Node, and Longitude of the Sun, are found the same way, by adding them for 12 or 13 Lunations. But the retrograde Motion of the Node for these Lunations must be subtracted from it’s longitude from Aries in _March_, to have it’s Longitude or Place in the _March_ following.
