1:30 Figure 3. — A curve plotted fromthe data of one experiment.The time interval in hours andminutes is represented on theabscissa; the value of the thres-hold in /5 units is representedon the ordinate. The continu-ous line is the curve of themuscle, the broken line that ofthe nerve-muscle. The curveof the nerve-muscle is magni-fied ten times, that of themuscle is normal. (1) Normal threshold stimulus.(2) The threshold after fatigu-ing the muscle for one hour. Themuscle contracted 120 timesper minute against a springhaving an initial tension of120 gm. (3) The thresholdafter five minutes rest. (4)The threshold three minutesafter the left splanchnic nerveswere stimulated for 30 seconds. the normal muscle expressed in /3 units.The threshold of the nerve-muscle ismagnified ten times. In Fig. 3 thethreshold (at 2) was taken after themuscle was fatigued through its nervefor one hour, pulling 120 times a minuteagainst a spring having an initial tensionof 120 gm.
