ELECTROMOTIVE ACTION IN NERVE 



297 



If the above facts prove the existence of physiological changes 

 of state, i.e. such as are transmitted from the poles comparable 

 throughout with electrotonus they would seem to indicate a 

 satisfactory explanation of the hitherto irreconcilable experiments 

 of Bernstein, as well as of Hermann and his pupils. We have 

 already pointed out that with regard to anelectrotonus the 

 galvanometric effects in non-medullated nerve agree in every 

 particular with the results of Bernstein's rheotome method on 

 medullated frog's nerve. This is intelligible if it be admitted 

 that, at the given distance between galvanometer and exciting 

 tracts, the galvanic manifestations of excitation and of transmitted 

 physiological electrotonus alone take effect ; while the experiments
