As we will referto this very important point, the centerof oscillation, later, we deem it advisableto make its location very clear to themind of the reader. A line (c) drawn downward and hack-ward, at an angle of 60° from line b,through the condyle, indicated by thewhite cross, will merge into the centerof oscillation. And a line (d) drawnfrom the center of oscillation downwardand forward, at an angle of 00° fromline b, will intersect the point where linea crosses the occlusal plane (e). Thesetwo lines, c and d, form two sides of aperfect hexagon. The angle of thishexagon, opposite that shown at the Fig. 9.
