OPERATION VIII. To find the Azimuth of any Star.
FInd but the Lions Heart's Bearing, or his then true Place in the Heavens as before, and the String will cut the Hori∣zon on its true Azimuth. Now if you see the Star, you may perform this Operation without any of the former Postulats; for placing your Globe on a Meridian Line, and holding your String streight from the Zenith, do but move it in that posture by the direction of your Eye (as we show'd you in the first Section) till it be in the same Plane with the Star, and the Degrees of the Horizon under your String, give you the re∣quired Azimuth, which will now be about 45 Degrees West∣ward.
