Equinoctial 18°, or, 1 hour, 12 minutes in time, on April 9th—and 161° 30', or 10 hours, 46 minutes, in time, on September 2d.

Problem 5. To find the Declination, and right Aſcenſion of the fixed Stars, ſuppoſe Cor-Scorpio, and the Virgin Spike, and Cor-Leo—Bring each Star to the Meridian of the Index, North, and it gives the right Aſcenſion of Cor-Scorpio 244° 20', or 16 hours, 17 minutes, 20 ſeconds, in time, with 26° South Declination.—Obſerve the ſame rule with all the other Stars.

Problem 6. To find the Right Aſcenſion and Declination of the Moon, or a Planet, depends on two caſes, thus—Seek the Planet's Longitude and Latitude in the Nautical Ephemeris, for the time given.—So, Auguſt 7th, at noon, the Moon's Longitude is 22° 39' of Scorpio, or 7 ſigns, 22° 39', with 4° 57' South Latitude; then find this Point in the Zodiac on the Planisphere, and take the Right Aſcenſion and Declination of it, as in the laſt Problem by the Stars, and you will find the Moon's Right Aſcenſion 261° 40', or 17 hours, 27 minutes in time, and 27° 45' South Declination, as was required.

Problem 7. To find the Sun's Oblique Aſcenſion and Aſcenſional Difference on April 14th. Find his place in the Ecliptic 25° of Aries, bring it to the eaſtern Horizon, and you will ſee 11° of the Equinoctial riſe with it, which is the Oblique Aſcenſion required; then find the Sun's Right Aſcenſion as before, 23° 40' and ſub-
