TABLE 4. 

 Ash (mgs per c. c. organ-fluid i determined after the wet method (SO4 ash). 



We see at once that there is no difference in ash-content in the 

 fluid of a stimulated organ and of one which had not been stimulated. 

 Moreover I made ireezing-point determinations in both liquids. 



TABLE 5. 

 A in ° in organ-fluid. 



From these experiments it appears that during activity substances 

 pass into the organ-fluid which must be considered to be oi'ganic 

 substance, because the ash-content is not increased, whereas the 

 freezing point shows a very definite lowering. 



However incomplete these investigations may be, I have felt the 

 desirability of communicating them very briefly, the more because 

 I shall most probably not be in a position to take up the whole 

 pi'oblem once more and because the data published in the present 

 paper, to my opinion, may be a stimulus to a continued research 

 of the physical and chemical processes whicli take place during the 

 discharge of the electrical organ.
