The movements of surviving small intestine of cavies fed on adequate diets and on diets consisting chiefly of cereals were studied. In normally‐fed animals three types of rhythm were found: ( a ) fine contractions; ( b ) tonus movements of short duration; and ( c ) large sharp contractions‐the ( a ) movements preponderating and being very often superimposed on those of the ( b ) and sometimes of the ( c ) type. In animals fed on deficient rations various degrees of disordered rhythm were found of a hypersensitive or a hyposensitive type. The responses to adrenaline, bicarbonate, and phosphates were generally different from those found in normal animals.
