Savart Bell and Resonator

The hemispherical bell is made to vibrate by stroking it with a violin bow. If the resonating cylinder is turned toward the bell and its length adjusted by the slide until its resonate frequency matches that of the bell, the sound is intensified. The cylinder can be moved away from the bell and tilted up and down.

This piece of equipment cost $20 when it was purchased from Queen & Co. of Philadelphia.
