Fig. 25.—Tube-holder. A stand for the tube is necessary, and can be easily constructedby anyone possessing a little mechanical ingenuity. An ordinarylaboratory wooden retort-holder will be found to answer mostpurposes. When a patient is lying on a bed or couch, however,a larger holder will be required, such as the one shown inFig. 25. Many other excellent stands are in the market. The chiefrequisites are a firm, heavy base ; easy joints, capable of tightfixing and of ready extension in every direction, with arms ofsome non-conducting material, e.g., hard wood. The stand is oneof those details careful attention to which will be found essentialto the production of good work. As the tube hangs from the endof a long lever, it is readily made tremulous by the multiplicationof any motion communicated to its support. Clearly, a shakytube means a blurred photograph. 5—2 62 THE RONTGEN RAYS IN MEDICAL WORK

Fig. 27. — Rowlands Stand forTube and Conducting Wires. Suitable for bedside work. Fig. 26.—Stand (Watsons). ELECTRICAL APPARATUS AND METHODS 63 Operating-Table A simple operating-table can be made of a piece of board 6 feetlong, 2 feet broad, and 1 inch thick, mounted on firm supportsabout 18 inches high. The coil and tube-stand can be placed onthe floor, or on a second table close to the patient. By using thesmall mounted screen occasionally, it will be seen if the tube isemitting rays of good penetrating power—a simple precautionwhereby much subsequent disappointment may at times be pre-vented. If the process can be conducted in a dark room, theordinary screen will be available ; but if it be in a lighted room itis difficult for the inexperienced eye to determine whether thetube is at its best or not. In the latter case the fluoroscope,which, as already explained, is simply a screen mounted in astereoscopic camera, will be found of service.
