They are compact and simple in con- struction, and, as they work expansively, are most economical. They are recommended as specially suited for electrical purposes, on. account of their extreme regularity, and wherever great speed is required they are invaluable. These Engines are in operation at West Corridor (Space 18); The “Brush.” Co., North End; The British Electric Light Co. (Ground Floor East, Space 3); stand in North.
