PLATE XX. 



Fiq. 



-. 8, I. A jet of water under the influence of a vibrating tuning-fork 

 (384 vibrations per sec.), showing successive stages in 

 the formation of drops, and their phases of vibration. 

 The point of disintegration has been considerably raised 

 by the action of the tuning-fork, as may be seen by 

 comparison with fig. 1, which represents the jet before 

 the application of the tuning-fork.
