Having rectified the Globe for the Lati-tude, the Zenith, and the Sun’s Place, turnthe Globe and the Quadrant of Altitude, sotyBthat the Sun’s Place may cut the given De-gree of Altitude: then the Index will shewpe Hour, and the Quadrant will cut theAzimuth in the Horizon. Thus, ifatZcw-h, on the iothof August, the Sun’s Alti-tude be 36 Degrees in the Forenoon, the[Hour of the Day will be IX, and the Sun’sAzimuth about 58 Degrees from the South[Part of the Meridian.

Me Sun’s Azimuth being given, to place theMeridian of the Globe due North andSouth , or to find a Meridian Line whenthe Sun shines.

Let the Sun’s Azimuth be 30 DegreesRouth-Easterly, set the Horizon of the GlobeBpon a Level, and bring the North PolePto the Zenith; then turn the Horizonlabout until the Shade of the Axis cutsl JS many Hours as is equivalent to the Azi-muth, (allowing 15 Degrees to an Hour)the North-West Part of the Hour-Circle,
