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. unknown books
