Third—The distortion caused by theposition of the subject and the distortioncaused by the radiation of the energy,having been eliminated, the Fluoro-meter provides an acurate cross-sectionof the body or limb, and supplies anabsolutely correct right-angle, at theintersection of the lines of which theforeign object will be found in the bodyor limb. In its last analysis the Fluorometer cross-section is obtained, the two armsof the Fluorometer will present the char-acteristic single shadow on the field of thelluoroscope. Attachable to the arms ofthe Fluorometer are two pins or means of these sights, the foreignobject having been brought in line withthem and the proper adjustment havingbeen made, a correct line is produced,with the sights and foreign object coin-cident. By means of a metallic gratingof inch mesh, which is placed adjacentto one side of the body and consequently. consists, essentially, in a set of carefullydesigned metallic angle pieces, whichconform generally to the shape of thebody or limb, and which in their usein connection with the x-ray, are sus-ceptible of being squared with a simpleand conveniently adjustable table. Thepatient being laid on the table anda fluorometer appliance adjusted, asshown in the accompanying engrav-ing, the Fluorometer is brought withthe body, into the parallelism of the is, when the proper position of the one side of the Fluorometer, exactmeasurement can be made with the eyefrom the base line of the Fluorometerand from points on the circumferenceof the body, to the foreign object. Then,without moving the body or the Fluoro-meter, the tube is placed directly overthe subject for the purpose of obtain-ing the vertical line. By means of anadjustable cross piece which is placedover the arms of the Fluorometer,exactly the same result in a verticalway is obtained by viewing the subj
