The thresholds of double-condenser discharge current were measured on the sciatic nerve of <I>Bufe vulgaris</I>. The stimulating current produced by two-condensers discharge is consisted of two portions, i.e. ascending and descending portions. When the ascending time of stimulating current is short, the threshold is high, and the prolongation of the ascending time causes to lower the threshold values, and when an adequate value is chosen as the ascending time, the threshold becomes minimal. And further prolongation of the ascending time over that adequate value, the thresholds are elevated again.<BR>The wave form of the stimulating current which shows the minimal threshold value, does not coincide to that of action current. It was elucidated that the stimulating action was caused only by the ascending portion of the double condenser discharge current, and not by the descending porton.
