Static Shock, or the Leyden-Jar Spark.—This method of appli-cation is accomplished by first otfacJivu/ a pair of Leyden Jars to thepoles of the machine, and connecting their outer covering of tin-foil b>j abrass rod. The poles of the machine are then brought into close approxima-tion; because the strength of the shock is modified (1) by the size of thejars^ and (2) hy the separation of the poles.
