This Graduation of the Circumference of a Circle is effected by the aid of an instrument called a trisector which I contrived with the view of trisecting an angle by its assistance, but subsequently perceived that it could help to divide an angle into 5 equal angles, and recently discovered that it could contribute towards dividing the circumference of a circle into 360 equal degrees or arcs.
