This has worked out as agreat success as .the impulsive waivegiven the current by the slate wheelpropels the gas through the opening,and prevents any inverse current fromgoing through the tube. It has sincebeen found not necessary to use the slatewheel, as the trouble is avoided bydrilling the hole through the porcelainon an angle and not directly through.This fact was accidently discovered. My friend, Dr. Lester Custer, ofDayton, Ohio, has solved the problemof the Lodge type of interrupters byusing a quarter of a barrel, which islined with lead, for one electrode, andfilling that with bottles which he con-structed of porcelain, walls of differentthickness through which he drilledholes upon an angle and of different 02 WISCONSIN MEDICAL RECORDER
