Atkinsons Toepler electric machine is an electro-static machine, of A-106 McCLURE. high tension and large quantity, whose sensitiveness to atmosphericinfluences does not interfere with its practical working. It is made withtwo circular plates of glass, one stationary, the other revolving close infront of it; two sets of combs and two Le3^den jars, with a switch betweenthem. To the back of the stationary plate are attached two sets of paperand tin-foil inductors, connected with which are two wire brushes, and tothe front of the revolving plate are attached six metal carriers with.

Opposite parts of the plates and opposite inductors andcarriers become oppositely electrified, condensation takes place in the jars,and sparks pass between the sliding electrodes, which may be increasedto seven inches or more in length. Electricity is generated at once, andthe electric charge constantly sustained by the friction of the carriers STATIC ELECTRICITY AND MAGNETISM. A-107 and brushes ; heuce the machine remains in practical working-order underthe most unfavorable atmospheric conditions. The switch, as seen in the cut, is placed between the Leyden jars,and in connection with their outer coatings, so that the induced currentbetween them is controlled by the operator. As
