The skiagraphshows the trouble to come from an im-perfectly filled tooth. The apex wasamputated at a point where the root-filling stopped, as seen by this same andthe result was a perfect cure. Fig. 15shows another case before and afterroot amputation The bone fills inaround these amputated roots, makingthem very firm and serviceable.2238 Euclid ave., Cleveland, O.

The bete noir of the operator of aHoltz static machine, is the frequentloss of charge during the warmer monthsof the year, when the atmosphere con-tains a high degree of fractional satura-tion of moisture, which renders the airmore conductive of the high tensionelectrical currents. This variety of static machine has nopower to bring itself into primary ac-tion. It, therefore, requires charging,priming or exciting by some secondaryapparatus. Usually a small Toepler orWimshurst static machine is employedfor the purpose. (An entirely new andoriginal method of overcoming loss ofcharge, invented by the writer, will bedemonstrated to the members of TheRoentgen Ray Society when they meetin Buffalo next September.) Some makers inclose the charger inthe same case with the Holtz machine,placing it at one end thereof, where, bythe employment of switches or otherdev
