Analysis of Five Records of Single Response. ' 



The difference of potential between the proximal and distal contacts is given in 

 terms of relative negativity ( ) or positivity ( + ) of proximal as compared 

 with distal contact. (Distance between contacts = 10 mm.) The differences 

 of potential are given in decimals of a volt. 



especially in the fresh, nerve ; the first indications of its presence in 

 fresh nerve at 6 C. occur O002 second after the stimulation of the 

 plexus when the seat of this stimulation is 30 mm. from the proxi- 

 mal electrometer contact. The response is thus propagated from 

 the seat of stimulation at a rate of from 10 to 15 metres per second 

 under these conditions. This is confirmed by the time relations of 

 the culmination and commencing decline in the change, for in fresh 

 nerve this begins in about O'OOl second with a distance of 10 mm. 

 between the proximal and distal contacts. In the example of kept
