Abstract
WRITTEN round the practical use of quartz in vibrating systems, this monograph will be of interest to many classes of readers. It describes the preparation of suitable pieces of crystal from the natural material—apparently by no means a difficult operation—the connexions and mathematical theory of circuits involving these, and the physics of quartz. We should like to direct special attention to the illustrations, and particularly to the photographs of the electrical discharges which vibrating crystals can set up in a partial vacuum, and of the interference fringes seen with a crystal oscillator close to optical flat. It would be difficult to devise more beautiful demonstrations of the modes of vibration of rods and plates. Including as it does an extensive bibliography, the book serves a useful purpose in co-ordinating existing results, and can scarcely fail to stimulate further research.
