o The time of the southing or meridian transits of the fixed fars in pa. 46, may be found thus. On the noon of the day, preceding the night in which you want to know the time of the southing of any of those stars, find the

Sun's place in the Ephemeris, and with it take out of the above table his right afcnfion in time; this you may do by inspection to a minute, which will be sufficient for vour present purpose: Then from the right-afcenfion of

the star in pa. 46, subtract the right-ascension of the Sun, the remainder will be the estimate time of the far's southing, and will not differ from the true time above 2 or 3 minutes at most, which may be near enough for ordinary vses. But when great exactnels is required, reduce the Sun's place to

this efimate time, and with it find in the above table his right ascension to seconds, which being subtracted from that of the star, the remainder will be

This table shewing the mean langitudes of 60 stars to the beginning of the year 1780, their mean longitudes for any other time may be found if 50 leconds be added for 'ach succeeding, and subtracted for each preceding year, and proportionably for a part of a vear. Thus, to find the longitude of the firft ftar d, or s piscium, for Feb. 15, 1782, or a years and one eighb after the tabular time; here 2 times 501 sec. make 1' 47", which being added to the tabular longitude, gives 11° 6' 35" for the longitude repaired at the given time. The latitudes vary not.
