The action potentials of cat's ureter, in situ, accompanying spontaneous peristalsis were recorded and an electrophysiological character of the ureteral muscle-cell was studied. 1) The features of the bipolar action potential were same as those reported by other investigators, and further studies on them were laid aside. 2) The monopolar action potential was three-phasic : i.e. the first positive-, socond negative- and the last one ware interpreted as the ”field-effect” caused by the coming and foregoing impulse, respectively. The second negative wave indicated the action potential of the muscle0calls around the exploring electrode. 3) The monophasic sction potential could not be recorded through the suction electrode. Comparing it to the similar experiment on the frog's heart, this finding was thought to be caused by an insufficient suction or by the histological difference betweed the two preparations. 4) The tip of glass capillary electrode whixh was filled with Ringer's solution or with 3-molar KCl solution, was artificially brolen and inserted into the ureter. The records obtained by using this capillary as an exploring electrode were monophasic, and the possibility to see the monophasic action potential by these procedure was discussed.
