In the three foregoing experiments, the index was purposely 
moved so that, before the beginning of the experiment, the 
balls rested as near the sides of the case as they could, without 
danger of touching it ; for it must be observed, that when the 
arm is at 35, they begin to touch. In the two following expe- 
riments, the index was in its usual position.
