Forsters p. consists of a semi-circle of 12 in. radius, which is graduated on its inner surface indegrees and is fastened at its vertex to a vertical rod, so as to de-scribe a hemisphere when rotated. In the centre of this sphereshould be the nodal point of the eye to be examined. Thereis erected opposite the first rod a shorter rod, with a hollowed-out chin-rest. From this runs upward a narrow rod, bent at theend, which end stands exactly i m. below and i in. in front of thecentre of the arc of the p. To this end is fitted the lower orbitalmargin, which should also be i in. below and i in. in front of thenodal point. From the foot of this rod, and rotating around it,runs a wire bent as a quadrant, on the end of which is a .smallmovable ivory ball.
