(For figures 54 to 64 the equation for the X-axis was ; the drawings were then reduced to |.) Let us now measure the amplitude, or maximum of vibration, for each group. For this we take half the distance between the extreme point below and the extreme point above. The results are ,,, , , , , , , Reduced to the size of the curves on the gramo- 20O t50 100 50.
