Motion of arm by moving weights from — to + =6,27 
+ to — =' 6,13 
Time of vibration at -J- = y' 6" 
— = 7 6 
In the next experiment, the balls, before the motion of the 
weights, were made to rest as near as possible to the sides of 
the case, but on the contrary side from what they did in the 
9th, 10th, and 1 ith experiments. 
experiment xv. May 27. 
Weights in negative position.
