The majorityof the cases of sigmoidospasm are associ-ated with a contracture of the iliac colon;however, they may exist independentlyof each other. The iliac colon is ofextreme interest; it is always palpable;under normal conditions it can be madeto contract under the palpating fingers asa rather firm finger-like cord. The con- is partly converted into sodium sulphateand magnesium carbonate, substanceswhich increase the contractile phase ofperistalsis, according to Meltzer.12 Theremaining unconverted portion of mag-nesium sulphate stimulates the inhibitoryor relaxing phase of peristalsis, thus pro-ducing the well-known rush movement of adose of epsom salts. Meltzers definitionot tonus is as follows: The resultant

In spasmoi the iliac colon we find the presence of afinger-like cord which cannot be made torelax and which is often tender to pressure.The iliac colon can be reached by meetingthe magnesium sulphate solution by meansof the sigmoidoscope and a soft rubbertube, with the patient in the knee-chestposture. Recently we have been working withatonic conditions of the rectosigmoidapparatus and iliac colon. When magne-sium sulphate is taken into the stomach it effect of the antagonistic action may bemanifest at the same place and at thesame time. This is tonus. The degree ofcharacter of t
