Another problem in connection with the Moon that has puzzled astronomers for a long time and is still in the region of experimental science is what is known as the Secular equation. It is found that by taking the present mean motion of the Moon and applying the various equations, found necessary to bring the calculations into line with observations of the Moon’s position in the zodiac, a considerable difference is found to exist between the calculated place of the Moon and its recorded position at the time of ancient eclipses. According to our modern Tables, ancient eclipses happened sooner than they should have done, or, in other words, the Moon was more advanced in its orbit than our Tables require. The inference is that the Moon was formerly moving quicker in a smaller orbit than now, or conversely, the Moon is now receding and getting farther from the Earth. Consequently its action on the tides must be diminishing, and also its action on the equatorial mass of the Earth, which is considered to be the chief factor in the production of what is called the Precession of the Equinoxes. Yet whereas by one statement the disturbance due to the Moon is diminishing, another statement shows that the Precession of the Equinoxes is increasing! =Voila le debacle.= All these anomalies and contradictions are due, as I shall show in my new Tables and Thesis, to the importation of false factors into the problem of the Moon’s motion, which, in fact, is extremely simple, perfectly regular, and affected only by its anomaly or distance from the aphelion and, where the time equation is employed, by the increase of radius. Jupiter and Venus have no more action on the Moon than have Mars and Saturn, in fact none at all, and the only body that has any action upon the lunar orb is the Sun, which it exerts indirectly through its action on the Earth. These problems need not, however, vex the minds of the student of Astrology. It is sufficient for him that he has the place of the Moon calculated for him in the ephemeris reduced from the Nautical or other official Almanac. It is important, however, that he should know that such problems exist.
