If a normalgall-bladder is distended with bile, itshould show a projecting bulge at the levelof the ninth costal cartilage. The densitymay not be greater than that of the liver. In the majority of pathological condi-tions affecting the gall-bladder, includingbiliary calculi, the accompanying cholo-cvstitis leads to a thickening of the whole between the twelfth rib and the space between the inner border of thepyriform gall-bladder shadow and the outerborder of the psoas shadow is much greaterthan that between the kidney and thepsoas. Very considerable variations arefound in the relation of the gall-bladder tothe bony landmarks, and this is notalways due to the varying position of thegall-bladder, for the twelfth rib may belong and very oblique, so that the costo-vertebral angle is narrow. The gall-bladdershadow is then in relation to the twelfthrib and the last costal space. The long axis. Fig. 12.

This thickened wallwill show in a skiagram which is of theproper quality. Where the shadows of a collection of gall-stones are demonstrated, the shape of theorgan may be distinguished. The positionof the gall-bladder varies more than thatof the kidney in different individuals. Itmay occupy the space between the twelfthrib and the outer border of the psoasmuscle usually occupied by the shadow is an elongated pear-shapewith the apex abo^e. It lies nearer to thetwelfth rib than does the kidney shadow,and its long axis is not parallel to the outerborder of the psoas muscle shadow, as inthat of the kidney, but bisects the angle
