In another paper they admitted that when they changed from dogs to cats they did not get good pinch reactions, according to the law, until they re membered that they had always given the dogs a preliminary dose of castor oil. Even when they gave this drug to the cats they did not get as typical reactions as they got in the dog, and they had difficulties again when they tried to use rabbits. It seems to me that if the law were valid it should be easily demonstrable in all laboratory animals without the help of drugs and denervations.
The duodenum was pinched gently with the fingers between the two balloons. Note the increase in amplitude and tonus in the oral balloon with temporary inhibition and then an increase of amplitude of contraction around the lower balloon. ) POLARITY OF THE SMALL BOWEL 47 Monaghan and Harris ( 1 9 3 4 ) and Forster and Hertzman, watching exteriorized bowel in man, could not see any wave of inhibition out ahead of the waves which passed every so often over segments of A B FIG. 16.

With this backing from three of the leading physiologists in the world it is not surprising that the law or reflex should promptly have become one of the foundation stones of physiology.
