PITKIN, M. D., BUFFALO, N. Y. Since the discovery of the utility ofthe Roentgen ray in the practice of medi-cine for diagnostic purposes, static ma-chines of many kinds and descriptionshave been brought forward as generatorsof the lightning current employed to ex-cite the Crookes tube for their produc-tion. Having employed considerable timeand means to determine the relativemerits of these instruments, let me rap-idly pass in review the results of our in-vestigations. A cheap machine is dear at any price,poor in construction and meager in out-put, it endangers the patients body toelectrical burns which may even jeop-ardize his life. The Toeplar Static Electrical Machineis the easiest to excite and maintain in astate of charge but as this type of instru-ment often reverses its polarity while ino
