the crysto-scope. With, the other eye (the room not being darkened) he can lookdirectly at the wound. The current is interrupted and closed by the helpof a pedal. The tube is enclosed in a box, containing below a diaphragm,capable of effecting so small an opening that only a limited field of opera-tion is illuminated. In this way, and by a plate of lead glass inserted inthe front wall of the box, the operator is protected. The box is fixed ona support connected with one leg of the table, and revolves horizontally.Thus, it can be turned aside with a sterilized cloth, and when its use is 298 ELECTEO-THEEAPEUTICS. again required it can be turned back, and it will be at once over theformer position, above the fluoroscope. The forearms of the operator restcomfortably on movable supports. The illustration (Fig. 176) shows the path of the rays emanatingfrom the anode of the tube E, that is in the box BK. Through the open-ing B, in the diaphragm, we see the body K, containing the foreign body

Upon the fluoroscope L, inserted on the table O, this picture is ob-liquely reflected by the mirror S, in the dark chamber D, into the tele-scopic tube T. In that case the anode focus and the centre of the fluo-roscope M, marked by a little shot pasted on it, lie vertically one belowthe other. Thus it becomes easy to adjust any other body orthodiagraph-ically in line with the normal ray, as, for instance, the foreign body Fcontained in the hand K. If you move the point of a knife into theilluminated picture until its shadow covers that of the shot and alsothe foreign body that has previously been adjusted, then the point of theblade must be exactly above that of the foreign body. THE CLINICAL APPLICATIONS. 299 For the determination of the location of a foreign body, whetherin the eyeball or orbital cavitj, take two separate skiagraphs, with the - acLuiy■ ! patient t-;^^
