ESTERASE OF BEHAVIOR of Anatomy, Duke University School of Medicine, Durham, North Carolina (Received for publication May 25, 1938) DESTRUCTIONof acetyl by the enzyme esterase is thought to account for the short duration of the effect of a nerve stimulus (Dale, 1936). It has been shown that acetyl is liberated sometime after a motor nerve to striated muscle is stimulated (Dale, Feldberg Vogt, 1936); the amount of esterase present in the superior cervical ganglion is sufficient to accomplish the destruction of the acetyl liberated, presumably within the refractory period of that ganglion (Glick, 1938). The inactivation of esterase by eserine is well known (Gaddum, 1935). The behavior of amphibian embryos poisoned with eserine during the swimming stage is characterized by a gradual paralysis of the skeletal musculature, by a gradual loss of irritability to mechanical stimulation by the development of contracture. A similar paralysis contracture have been observed in amphibian embryos in the early swimming stage after they had been made to swim continuously for a few minutes by repeated mechanical stimulation. Therefore, it would seem that the slow relaxation of young amphibian embryos in the flexure, âU,â coil stages, their quick fatigue through the early swimmin g
