The sciatic nerve or sartorius muscle was stimulated by rectangular shock, and anodal break excitation was observed. For to exclude the cathodal stimulating effect, the authors employed the following methods. The nerve was crushed between the anode and cathode, so that the impuls evoked at cathode could not propagate to the anodal side. The muscle was cut at its end with burned knife edge, and the cathode was placed on that injured surface, for to inhibit the cathodal excitation. Strength (V) duration (t) curve was hyperbolic and valid to WEISS's experimental formula. HILL's accommodation constant λ was calculated from the experimental results. Its numerical value was 5.864±1.086 msec. for nerve and 11.2±5.7msec. for muscle. HILL's theory of electrical stimulation published in 1936 postulate the relation V/V_0=1/1-e^<-t/λ> in case of anodal break excitation. This theoretical formula was valid very well for the present experimental data.
