First Edition, offprint issue. Cannon was the first to use x rays to study the digestive system; his work laid the foundations of gastrointestinal radiology. The present paper, written while Cannon was still a medical student, describes Cannon's first experiments with x-rays to examine the mechanism of swallowing, including his first public demonstration, by means of x-rays, of the phenomena of deglutition. This ground-breaking work was undertaken less than a year after Roentgen's discovery of the x-ray. DSB.
