Stomach Meter Aids Study of Digestion (May, 1939)
Stomach Meter Aids Study of Digestion
Subjects who don’t amind the inconvenience of dining after having swallowed an electrode at the end of a long rubber tube, are solving mysteries of digestion at the Philadelphia College of Osteopathy. Through the tube, wires lead to an electric meter that constantly records acidity changes in the stomach. One enthusiastic volunteer actually ate his way through college; paid two dollars every time he gulped down the “antimony gastric electrode,” he also got his meals free, thus saving on his board bill.
