Hence the apparent Time may be found from an observed Altitude of a known fixed Star, suppose one contained in Page 7, of the Requisite Tables, as will be explained hereafter. The Suns right Ascension in Time is also useful for computing the Time of the Moon and Planets passing the Meridian, as will be shown under their proper Articles. -. . The Suns Declination is necessary to find the Latitude, whether at Sea or Land, from the Meridian Altitude observed: it is also requisite for finding the Latitude from Two Altitudes observed, with the Interval of Time measured by a watch; it serves for computing the Suns Azimuth, having his Altitude and the Latitude of the Place given, in order to find the Variation of the Compass; it is required, jointly with the Latitude of the Place and the Suns horary Angle, to compute his Altitude if neglected to be observed at the time of taking the Moons Distance from the Sun for finding the Longitude, being useful to facilitate the Calculations of the Effect of Refraction and Parallax upon the Distance; it is also necessary to calculate the apparent Time from an observed Altitude of the Sun at a Distance from the Meridian, the Latitude being given; or to compute the Time of the Suns Setting or Rising; which, though a less accurate Method than the former of obtaining the Time, may yet be useful when that cannot be had. For any of these purposes the Suns Declination must be found to the Time, given nearly, reduced to the Meridian of Greenwich, making Proportion according to the Daily Increase or Decrease, in like Manner as was shown with respect to the Suns Longitude. .
