The stomach-tube should not be too small; for an adult it should be from 30 to 35 French scale. It should not be too flexible; it should support its own weight held in the upright position for the length of twelve indies without bending. It should have the largest caliber possible without making it liable to bend sharply at an angle when pressed on. A good deal depends on the quality of the rubber; much depends on the character of the tabe. It should have no pumping apparatus connected with it and it should be about 54 inches long.
On the introduction of the tube it is occasionally grasped by the esophagus about 8 or 10 inches from the teeth, if this delay is temporary, it depends on spasm, and one may expect to find either cardiospasmus or stricture at the cardia.
