278. All these things will be made plain by putting small patches on the Ecliptic of a Globe, as far from one another as the Moon moves from any Point of the celestial Ecliptic in 24 hours, which at a mean rate is [62]13-1/6 degrees; and then in turning the globe round, observe the rising and setting of the patches in the Horizon, as the Index points out the different times in the hour circle. A few of these patches are represented by dots at _0_ _1_ _2_ _3_ &c. on the Ecliptic, which has the position _LUI_ when Aries rises in the East; and by the dots _0_ _1_ _2_ _3_, &c. when Libra rises in the East, at which time the Ecliptic has the position _EU_♑: making an angle of 62 degrees with the Horizon in the latter case, and an angle of no more than 15 degrees with it in the former; supposing the Globe rectified to the Latitude of _London_. 279. Having rectified the Globe, turn it until the patch at _0_, about the beginning of ♓ Pisces on the half _LUI_ of the Ecliptic, comes to the Eastern side of the Horizon; and then keeping the ball steady, set the hour Index to XII, because _that_ hour may perhaps be more easily remembred than any other. Then, turn the Globe round westward, and in that time, suppose the patch _0_ to have moved thence to _1_, 13-1/6 degrees, whilst the Earth turns once round its Axis, and you will see that _1_ rises only about 20 minutes later than _0_ did on the day before. Turn the Globe round again, and in that time suppose the same patch to have moved from _1_ to _2_; and it will rise only 20 minutes later by the hour-index than it did at _1_ on the day or turn before. At the end of the next turn, suppose the patch to have gone from _2_ to _3_ at _U_, and it will rise 20 minutes later than it did at _2_. And so on for six turns, in which time there will scarce be two hours difference: Nor would there have been so much if the 6 degrees of the Sun’s motion in that time had been allowed for. At the first Turn the patch rises south of the East, at the middle Turn due East, and at the last Turn north of the East. But these patches will be 9 hours of setting on the western side of the Horizon, which shews that the Moon will be so much later of setting in that week in which she moves through these two Signs. The cause of this difference is evident; for Pisces and Aries make only an Angle of 15 degrees with the Horizon when they rise; but they make an Angle of 62 degrees with it when they set § 275. As the Signs Taurus, Gemini, Cancer, Leo, Virgo, and Libra rise successively, the Angle increases gradually which they make with the Horizon; and decreases in the same proportion as they set. And for that reason, the Moon differs gradually more in the time of her rising every day whilst she is in these Signs, and less in her setting: After which, through the other six Signs, _viz._ Scorpio, Sagittary, Capricorn, Aquarius, Pisces, and Aries, the rising difference becomes less every day, until it be at
