                                Sketch of an experiment to detect the playing of a musical box using an Alison differential stethoscope. The experimenter is holding the stethoscope tubes on the dry and wet surface of a tilted dinner plate to show that water augmented faint sounds. The musical box is in the foreground of the picture.
