    tinctl}^ visible ia the mirror below. This enables the operator to make a fluoroscopic examination of the part to be radiographed before adjusting the photographic plate for exposure. If the placiag of the patient is not satisfac- tory, as oljserved fluoroscopically, the position is altered until a proper posture is obtained. Thereupon the tray is lowered and the plate slid in through the window until it comes into position under the celluloid, controlled by the guides above referred to. The tray is now raised, so that the plate is brought within inch of the part to be radiograj)hed. The exposure is made and the tray is lowered. Tdie inclined plane on which the tray rests allows the tray and plate to slide out into the operator’s hand. Another plate is inserted, the tra}^ raised, another exposure made, and so on. For stereoscopic plates, two holders are placed on the tray in line with each other, so that when the frame is brought up parallel to the table top, the proximal plate comes under the celluloid opening, and the distal plate under the lead protection beyond. The focus tulje-stand is connected with the tray by means of a cord. The first exposure is noAv made. The tray is lowered, allowing the exposed plate to slide out under the proximal lead protection, and bringing the second plate under the celluloid diaphragm; and at the same time the tube-carrier is automatically shifted the proper distance. The second exposure is then made. The great advantage of this method is that there are no springs to stick, and the operator knows absolutely that the plates have been properly shifted. A vertical arrangement stands at the left end of the table. It contains a celluloid window, and a tra}^ with a fluorescent screen and mirror behind it, so that after making an examination in the horizontal position, the patient is radiograx^hed in front of the vertical opening by means of the same tube and tube-carrier before used. The x:»lates are changed from the cabinet^in a manner similar to that just described. The construction of this a|)paratus allows for teleradiography in both the prone and erect postures.
