gineers and students. The author gives simple descriptions of the very latest Brush dynamos and a list of instructions for use in emergencies. A novel feature is a revolvable celluloid chart. This chart represents a Brush dynamo with a revolvable armature. It shows the manner of cutting the lines of force, the directions of the flow of current induced in the armature coils, the method of commuting the current, and the flow of current to the external circuit and return to the negative brush. The book has been approved by the Brush company. (N. W. Henley & Co., N. Y.)
