Abstract

A pH-telemeter was used to determine the hydrogenion concentration in the digestive tract of the dog continually. When a dog was starved, the pH ranged from 1.4 to 2.0 and from 5.5 to 7.9 in the stomach and intestine, respectively. When feed was given to this dog, the pH increased to 4.3 in the stomach, but showed no marked changes in the intestine. It also remained unchanged in the intestine even when a starved dog was fed after the radio capsule had been moved to this organ. This capsule stayed longer in the stomach when a dog was fed than when it was starved.
