SENSORY FARADIC THRESHOLD.

large capacity. The amount of the current was regulated by two slide 

 resistances, of which the fine adjustment only is represented in figure 14 

 as a slide-wire resistance at the front of the table. 



Application of the electrodes. The fingers to which the electrodes 

 were applied were usually the index and middle fingers of the right hand. 

 In case of abrasion of either of these fingers, or for any accidental reason 

 that rendered their use inexpedient, the third and fourth fingers of the 

 same hand were used. 



RESULTS. 



A full summary of our available data on the sensory threshold to 

 electrical stimulation by the Martin method is given in tables 22 and 23. 



TABLE 22. Threshold measurements for Faradic stimulation. 

 [Values given in Martin units.] 



Differences equal periods 1-2, 1-3, 1-4, etc. 



2 The values in the first period were obtained before the alcohol was given, and are therefore 

 not included in the averages. Insufficient data.
