44. minutes, The Globe and Quadrant of Altitude Recti∣fied, as by Prob. 1. I bring the Quadrant of Altitude to 85. de∣grees 15. minutes of the Horizon, the measure of the Angle C: Then I turn the Globe till 79. degrees 15. minutes of the first Meridian (which is the measure of the Leg A B) touch the Qua∣drant of Altitude, so is the Triangle made on the Globe. The Arch of the Equinoctial comprehended between the first Meridian and the Brasen Meridian shews the length of the Leg C A 23. de∣grees 8. minutes; the Arch of the Quadrant of Altitude com∣prehended between the Zenith and the first Meridian, shall shew the length of the Hypothenusa C B 80. degrees 8. minutes: The Right Angle made at the Intersection of the Equinoctial and the Brasen Meridian is 90. degrees: And to find the measure of the Angle B, you must turn the Triangle, as you were directed in Prob. 1:
