Utilizing exponentially increasing currents of various time constants, the authors stimulated the sciatic nerve of Bufo vulgaris and measured its threshold voltage (V). And then the rheobasic voltage V_0 was determined. The accommodation curve which indicates the relation between V/V_0 and time constants of stimulating currents was pursued, and from this curve the accommodation constant λ was calculated. Its mean value was 103.23±36.03 msec or 287.81±55.53msec, each corresponding to smaller or larger time constant. The values obtained were smaller than that of muscle, which was measured in the same experimental condition as the authors' by Sirasawa in this instutite. The authors could elucidate the reason why "Einschleichen" occurs more easily in nerve than in muscle.
