Measurements have been made on the dielectric properties of some of the natural crystals, and it has been shown that the values of the constants are changed upon exposure to ultraviolet light. The most important of these properties are dielectric constant, phase angle, and resistance, all of which show this variation when exposed to the short wave-lengths.
