The popularity of theMurphy button gives frequent opportunities to observe its char-acteristic shadow while it travels through the intestinal tract. 132 THE RONTGEN RAYS Tumours of the Stomach are representable only if their textureshows a considerable degree of density. The outlines of the stom-ach can be mapped out if the viscus is filled with salts, such as sub-nitrate of bismuth, that are impermeable to the rays. The intro-duction of a soft rubber tube the lumen of which is filled withmercury is, however, preferable. A rubber tube containing a thin,flexible steel wire in a spiral form, as advised by the author, per-mits the rapid representation of the outlines of the stomach. Thestoppage of this tube indicates its arrival at the large curvature ofthe stoma
