| VARIATION OF CAPACITY WITH TEMPERATURE OF PAPER CONDENSERS SS {S. Smith} STANDARD CONDENSER SEALED AT THE ENDS WITH STICKILENE VARNISH. IC.1 CONDENSER WITH CONNECTING STRIPS WRAPPED IN TINFOIL OF CONDENSER TO OBTAIN BETTER CONNECTIONS. OTHERWISE STANDARD. THE POINT 'L' ON EACH CURVE INDICATES THE TEMPERATURE AT WHICH THE CONDENSER BEGINS OR CEASES TO HAVE AN APPRECIABLE LEAKAGE, JUDGED BY ITS CAPABILITY OF HOLDING OR NOT HOLDING AN APPRECIABLE STATIC CHARGE.
