Abstract
The intestinal movement, when incurred, was observed through the abdominal window of the rabbit sensitized with mucus membrane of rabbit. The following results were thus obtained
1. The intestinal movement in vivo at the time when the same extract was given again to the parentally and orally sensitized rabbit was found accelerated, and the intestinal hyperaemia was marked generally.
2. The degree of the acceleration of the intestinal movement, when incurred, was more marked on the orally sensitized rabbit than that of the parentally sensitized one.
3. The antibody level in the blood was negative without distinction of the method of sensitization.
