It is to be observed that the use of the statute hour in connection with planetary action has arisen from the consideration of their universality, and an equatorial scheme in which the Sun rises at six o’clock approximately would thus yield a day of twelve hours, and each quadrant would embrace six hours of little more or less than sixty minutes each in duration. But the application of the statute hour to sunrise in high northern latitudes would appear to be without adequate foundation, and in effect we find that the results depending thereon are not consistent. It is these inconsistencies, arising from the introduction of new elements into the ancient scheme, and the general neglect into which the whole subject has fallen, that has given the impression that the ascriptions are fanciful and the matter not worth investigation. I know enough of the matter, however, to warrant my calling attention to these Planetary Hours as most worthy of close study by students of celestial influence. A considerable field of research lies open to the diligent student. It has to be finally determined, for instance, whether apparent sunrise is to be taken as the basis of the calculations or the true Sun’s centre rising. The latter is not subject to corrections for parallax, nutation, and aberration, but depends on the rising of the Sun’s longitude on the celestial horizon, the false horizon being ignored. The celestial horizon, it should be observed, is always 90° from the Zenith. The formula for this calculation is: Log. tang. latitude of place + log. tang. Sun’s declination = log. sine of Sun’s ascensional difference. For North declination add to 90° and for South declination subtract from 90°. The result is the semiarc diurnal of the Sun, and twice this is the diurnal arc or the time the Sun remains above the horizon. Convert to time at the rate of four minutes for every degree and four seconds for every minute of arc. We have then to determine whether sunrise is the correct starting point, or whether it should not be noon, as in agreement with the original Chaldean conception of the division of the circle into “evening” and “morning.” I may say that in my experience the count should be made from sunrise, that the true Sun’s centre rising should be taken, and that the Chaldean order of the Hours should be preserved. I have also found that the subdivisions play quite a minor part in the determination of results, and that all events falling within the limits of the Planetary Hour should be found subject to the ruler of that Hour, and only in a subsidiary degree to the ruler of the subdivision of the Hour. I may now pass to a consideration of another aspect of this interesting subject. CHAPTER XVII CELESTIAL MAGNETIC POLARITIES
