PHENOMENA OF MUSCLE AND NERVE.

with one of the polarising electrodes, and the extrapolar led-off 

 part brought thus immediately up to the polarised region. One 

 leading-off electrode was therefore placed with its kaolin point on 

 the kaolin of one of the leading-in electrodes. 



In this case the phenomena appeared still better and with more 

 regularity than they did with the ordinary method. 



Example of an experiment on nerve. Two sciatics lying side by 

 side in alternating directions. Leading-in contacts at AB. Lead- 

 ing-off' contacts at cc'. Electrodes c and B united. Short duration 



of closure'.
