While engaged in my work, which requires a large amount of gastric analysis, I have encountered many difficulties and inconveniences. These I shall briefly enumerate in order to emphasize the advantages which are obtained through the use of the apparatus and methods I am about to describe.
One of the greatest drawbacks of the old method is the difficulty of obtaining a satisfactory specimen of fasting content because of the frequent failure of the stomach tube to reach the lower level of the stomach.

This frequent failure to obtain a sufficiently large specimen is also characteristic of the use of the stomach tube after an Ewald test meal, a difficulty which
