But they have been made unusuallylarge and of the very best Iridio-Platinum obtainable. Aside from thecontacts, the only parts which may need renewing are the springs,which once in a great while crystallize and break under the strain ofconstant bending. The contacts should last for a year with constant use, while thesprings are likely never to need renewing. In short we recommend the Roentgen Self-Starting Me-cKanical Interrtipter as the most efficient, most reliable, andmost satisfactory of the various mechanical interrupters which areoffered to-day.

Tij COMPLETE interrupter with adjustable condenser and switchesKA as shown can readily be adapted to coils whose operation is ^^ rendered unsatisfactory because of the inefficiency of the in-terrupter. The output of an induction coil, operated by the ordinarymechanical interrupter, can be materially increased if the RoentgenMechanical Interrupter be used in its place. James Q.
