Most experi-menters believe that there is some formof tissue disorganization, but do notattempt to specify the nature of thechanges, except the collection of acid andalkali at the opposite electrodes. Effects Depending on Position of Elec-trode. When the electrodes are appliedto the neck and body the effects are moresevere (Exp. 6, 7, 9, 10) than when appliedto the ankles (Exp. 8).

High Tension Electric Shocks in Roentgen ologic Practice 369 currents applied to the ankles did notcause respiratory paralysis, but they wereof short duration—two seconds. SOURCE OF ELECTRICAL DANGERS Martin states that currents of highvoltage and high amperage are alwaysdangerous; currents of high voltage butlow amperage are not necessarily fatalunless the subject forms a short circuitto ground or between two high tension wires.Currents used in roentgen-ray work are ofvery high voltage, but of amperage mea-sured in thousandths of an ampere—verylow. Accordingly the source of high tensiondangers in roentgenologic practice are:(1) grounds and (2) unguarded wires andtube terminals. Grounds. The problem of grounds andhow to avoid them is not as simple as onemight suppose. It requires a considerationof not only what will happen when every-thing goes right, but also what mistakesthe operator is liable to make, whatmovements it is possible for the patientto make, and what accidents may h
