Thus, if you turn your face towards the North, you will find the North Pole of the globe points to the _Pole-Star_; then you may observe two Stars somewhat less bright than the Pole-Star, almost in a right line with it, and four more which form a sort of _quadrangle_; these seven Stars make the constellation called the _Little Bear_; the Pole Star being in the tip of the tail. In this neighbourhood you will observe seven bright Stars, which are commonly called _Charles’s Wane_; these are the bright Stars in the _Great Bear_, and form much such another figure with those before-mentioned in the _little Bear_: The two foremost of the square lie almost in a right line with the Pole Star, and are called the _Pointers_, so that knowing the Pointers, you may easily find the Pole-Star. Thus the rest of the Stars in this constellation, and all the Stars in the neighbouring constellations may be easily found, by observing how the unknown Stars lie either in _quadrangles_, _triangles_, or strait lines from those that are already known upon the globe.
After the same manner the globe being rectified, you may distinguish those Stars that are to the Southward of you, and be soon acquainted with all the Stars that are visible in our hemisphere.
The globe being rectified to the latitude of any place, if you turn it round its axis, all those Stars that do not go below the horizon during a whole revolution of the globe, never set in that place; and those that do not come above the horizon never rise.
PROB. XXXVII. _The latitude of the place being given; to find the Amplitude, Oblique Ascension and Descension, Ascensional Difference, Semi-diurnal Arch, and the time of continuance above the horizon, of any given point in the heavens._
Having rectified the globe for the latitude, and brought the given point to the meridian, set the index to the hour of 12; then turn the globe until the given point be brought to the Eastern side of the horizon, and that degree of the equinoctial which is cut by the horizon at that time, will be the _Oblique Ascension_; and where the given point cuts the horizon, is the _Amplitude Ortive_: If the globe be turned about until the given point be brought to the Western side of the horizon, it will there show the _Amplitude Occasive_; and where the horizon cuts the equinoctial at that time, is the _Oblique Descension_.
