THE PHENOMENON OF CONTRACTION. 33 This condition is often exhibited in a most interesting way when a muscleis repeatedly stimulated. In some cases it develops at the beginning of aseries of contractions, as is represented in Fig. 14, which pictures the phenome-non as it was first described.* In other cases it appears later on in the curve,. Fig. 15.—Effect of repeated stimulation; complete curve, showing late muscle was stimulated by induction shocks at the rate of 50 per minute. The separatecontractions are so close together that they can not be distinguished. preceding or following the development of the state of fatigue. Wheneverit occurs the effect is to hold the muscle in a state of maintained contraction,on which is superposed the series of quick contractions and relaxations dueto the separate stimuli. When the condition develops early in the functionalactivity of the muscle (Fig. 14) further activity usually causes it to disappear,
