t the arms ofthe fluorometer cast but a single shadowupon the field of the fluoroscopy thenmove the limb or body until the shadow ofthe object or fragments of the bones infracture, etc., sought, are brought to theshadow of the now coincident arms ofthe fluorometer appliance. The operatorwill here observe that if the limb or bodywere severed at this point the object wouldbe found in the indicated cross section.At this point place one of the sights onthe arm of the fluorometer nearest the take the straight connected instrument,and place it over the arms of the fluoro-meter to ascertain the distance from eitherof the two points. Place the tube underthe aperture in the table, at a safe distance,and repeat the same procedure, and markthe final position with silver nitrate, etc.,as before, on the cross section as indi-cated. The object sought will be foundat the intersection of the horizontal andperpendicular lines. The markings haveto correspond exactly with the fluoromet-ric measurements.
