Page 32 - Poie, at different distances of the Star from the Meridian. As the pole star is generally known, that no opportunity, therefore, may be lost for determining the latitude, this table is inserted, the use of which is as follows : — Find the interval between the time of observation of the altitude of the pole star, and that of its passing the meridian, and take out the corresponding equation from the table ; which added to, or subtracted from the true altitude of the pole star, will give the latitude...
