ELECTRICITY AND THE GROWTH OF CHILDREN.

At the suggestion of Prof. Svante Arrhenius, an experiment is being tried in Stockholm on fifty school children. The children £.re divided into two groups identical in point of health, height, weight, etc., and are placed in two class-rooms of the same dimensions, and similarly situated as regards exposure to light. In each class-room, exactly the same teaching is given, but one of the class-rooms is subjected to electricity, while the other is not. As yet the experiment has not been drawn to a close, but it is reported that the "electrified children" have shown a greater mental and physical development than those in the other classroom.
