Abstract
1. Sodium phenobarbital in most instances when injected intravenously in large doses, causes a lowering of general tonus of the Thiry-Vella loop of intestine in non-anesthetized dogs.
2. Morphine sulphate counteracts the effect of sodium phenobarbital and in most instances sodium phenobarbital will lower the increased general tonus produced in the gut by a previous injection of morphine.
3. Morphine sulphate causes an increase in the general tonus of the intestine even though the tonus has been lowered by a previous injection of pituitary extract.
4. Pituitary extract temporarily lowers the increased general tonus of the intestine produced by the injection of morphine sulphate.
