38 of the Ecliptic, at an Angle of 5° 18' at the mot; the Moon never remains in the Ecliptic, but interects it twice in a month, in the points called her Nodes, or the Head and Tail of the Dragon; or, thee are the points in which the Moon's Orbit biects the Plane of the Ecliptic, and while he is in that half of her Orbit, which is on the South ide of the Ecliptic, he is aid to have South Latitude; and the point of the Ecliptic where the Moon paeth out of South, into North Latitude, is called her North Node, or Head of the Dragon, and then he hath North Latitude, till he arrives at her South Node, or, to the Dragon's Tail. The Nodes of the other Planets, according to Geocentric Viion, are, in thoe points of the Ecliptic where they have no Latitude, which are een in the Nautical Almanac. I need not premie farther, in order to this Problem.

Required the Moon's true place on Sept. 15th, 1802, at 7h 24m, P. M. Find in the Nautical, or in any good Ephemeris, her Longitude at noon on the 15th, 1s 10° 49', and ubtract it from her Longitude on the 16th, at noon, 1s 24° 41', and the difference is, 0s 13° 52'; then ay, by the rule of proportion, if 24h give this Arc 0s 13° 52', what will the time from noon, 7h 21m give?—Anwer, 4° 16', which, added to her Longitude the 15th, at noon, makes it 1s 15° 5', her true and corrected Longitude at the hour and minute required. But note! this is not the moon's true place in the Zodiac; for, against the 15th at noon, he hath 4° 33" North Latitude, which, ubtract from her Latitude the
