The subjoined table contains the width of the first 8 reflections 

 which were reproduced photographically; at the same time the 

 duration of these 8 reflections was calculated. 



From this it appears that in comparing the first 8 reflections not 

 only the amplitude changes, but that also the time in which these 

 oscillations take place, varies with the greater or smaller degree of 

 hardness of the muscle. As the experiment progresses, it may be 

 observed in the table that the heights of the reflections are getting 

 larger also at the moments when the muscle is not excited. This 

 must be connected with the changes in the constant state of con- 

 traction (autotonus), which arise in every fatigued muscle. That the 

 muscle becomes really tired, is proved by the fact: 1. that the 

 muscle visibly contracts less, 2. that changes in duration and height 

 of the reflections diminish after repeated excitement, 3. that after the 

 rest the effect of excitement agrees again with what was observed 

 in the beginning of the experiment. 



We add a tabulated statement of an experiment in which the 

 muscle at the end of the experiment had become entirely inexcitable, 

 as appeared from the absence of visible contractions, both for 

 indirect and direct faradaic excitement, though still slight alterations 

 in hardness appeared to be perceptible.
