The determination was made according to Pflüger : 



TABLE 3. 



If we compare these results with those of Baglioni ^), we see that 

 the glycogen values in exp. 1 and 2 are lower than those given by 

 Baglioni (0,09 7o)> t^^t of the same order. The figures in very young 

 animals (exp. 3 and 4) are very much higher. 



If the electrical organ functions by splitting up ion-proteids, 

 we may expect salts to become free. This might be the 

 explanation of the increase of the watery extract found by Wkyl. 

 The electrical organ reacts to mechanical stimulation, e.g. mincing 

 or pressure, by strong activity. Therefore I have tried to divide 

 electrical organs finely by gradually cooling and finally freezing 

 them. In that way no discharges occurred. In centrifuging the frozen 

 organ after it had been ground up, I could obtain a very complete 

 separation of the organ-fluid. This fluid as obtained from stimulated 

 and fresh organs, was used for the present research. 



In the liquid thus obtained I made a determination of the ash- 

 compounds, which led to the following results:
