    tissues is readily determined from a study of the planes of shadow at the two exposures. When the skiagraphs of the case here reported were made, the anterior surface of the leg was placed upon the bottom of the right angle support of the apparatus, the plate to the inner side of the knee, one indicator-ball resting on the skin nearly in the center of the popliteal space. The skiagraph made ^yith the tube horizontal with the plane of the indi- cators is shown in Fig. 3, and the second skiagraph with the Fig. 2.—Dr. Sweet’s localization apparatus. tube a short distance above the first position is seen in Fio-. 4. Both negatives show the leg as viewed from the outer side, with the posterior surface of the leg uppermost. In determining the position of the bullet a spot is made upon paper to indicate the point on the skin at which one of the indicator-balls rested at the time of the exposures a second spot being made 2 inches from the first, to represent the fixed distance between the two balli. These are shown
