  1. The acidulated water was caused to splash up against the membrane by the vibration of W and the membrane soon ceased to respond to the voice until tightened.

    2. Water Dish

  2. The more deeply the point P of the tuning-fork f (Fig 2) was immersed in the water the feebler the sound from S.

  3. A large number of experiments made to test the effect of varying the surface of W exposed to the liquid have convinced me that the amount of surface exposed at W has little or nothing to do with the effect. The sound proceeding from S was sensibly as loud when the mere point of W touched the water as when a large mass of metal (connected with W) was immersed in the water.
