In the study of the diarrheas accompanying gastric achylia, it is essential that we have a rational conception of that condition. It is my intention in this paper to consider first some studies which we have carried out on achylia and then to follow it by our observations on the form of diarrhea accompanying that condition. In a former contribution, I pointed out the fact that by means of fractional analysis, it was possible to throw considerable light on certain phases of achylia and to make two broad distinctions, namely, a differentiation between true and false, or spurious, achylia, the former being a condition which persists throughout the entire stage of gastric digestion, the latter being simply a form of delayed gastric secretion,
since after a period of one hour and a half there is to be found a perceptible secretion. If this method had been employed in previous studies
