Again, in practice, I proceed as follows:The patients knees are flexed. An 8 by 10plate is placed crosswise under, sav. the right raised. The cylinder is now tilted about 10 to25 degrees to point up under the ribs, andfixed in this position, and pushed up underthe ribs as far toward the patients head ashe will allow, and fixed in this position. Fin-ally, the tube and cylinder, sliding on thehorizontal arm of the tube-stand, are movedas far towards the right as the patient will. Fig. 3.

The cylinder is thentilted between 5° and 10°, so as to point to-ward the right. At this angle it is loweredonto the patient slightly to the right of themedian line, brought down with a fine ad-justment device as tight as the patient wUeasily allows and fixed so that it cannot be allow, and fixed in this position. This lastmovement will pull the ribs over to a con-siderable degree and it is necessary to in-struct the patient not to turn toward theright side, and not to allow his back to slipon the table with an inclination to follow themovement of the tube. With everything fixedand rigid, the exposure is made. While the preparation of the patient isimportant, it is not essential in every case. ii8 Technique of Roen
