Pre- sumably, all the eyestalks contain both substances but in differing amounts. These substances are certainly antagonistic to each other. The results from the experi- ment of gel nitration of the supraesophageal ganglia with the circumesophageal connectives attached (Fig. 5) revealed that this antagonism can be strong enough to inhibit completely the response to one of the substances. z ° 6 c/l Q.
