EXPEPaMEXT 203. 



In this experiment, as iu " Experiment 198," weighting the mnscle 

 greatly influenced the eiiect of polarization on the excitability of the 

 nerve. 



I could multiply these experiments almost indefinitely, having made 

 upwards of 500 of them, but these few will suffice to justify the conclu- 

 sions at which I have arrived. It is true that the experiments given 

 are all made with the irritation applied jieriiiherally from the polariza- 

 tion, but I have made numerous experiments where this relation was 

 reversed which gave the same results. These may, however, be the 

 subject of a future paper.
