If a .JP solid circle be fixed in any one position and a tube be pivoted on its centre so as to move; and if the line C D be drawn upon the circle pointing towards any object Q in the heavens which lies in the plane of the circle, by turn ing the tube A B towards any other object P in the plane of the circle, the angle B 0 D will be the angle subtended by the two objects P and Q at the eye.
If P, P be consecutive positions of the same point, and the corresponding angle of rotation, then ultimately PP is at right angles to JP and equal to JP. ~O.
