94 POLARIZED CONDITION OF THE OHAP. IX. 



muscular current still existed; fifteen minutes, no 

 nerve current, nerve dry, muscular cuirent but slight; 

 twenty minutes, no effect ; twenty-five minutes, no 

 efiect. 



With the current from three cells, after five 

 minutes, the nerve current very slight, the muscular 

 current somewhat diminished ; after ten minutes, no 

 nerve current, nerve dry, muscular current slight; 

 fifteen minutes, no effect from nerve, muscular 

 current very slight ; twenty minutes, no effect from 

 either ; twenty-five minutes, no effect. 



With the current from dx cells, after five minutes, 

 no nerve current, nerve dry, muscular current very 

 slight ; after ten minutes, indefinite indications of 

 the needle with the nerve, no muscular current; 

 fifteen minutes, no effect with nerve, with the 

 muscle the current occasionally indicated a reversed 

 direction ; twenty minutes, no effect with the nerve, 

 indefinite indications of the needle with the muscle ; 

 twenty-five minutes, effects similar to those last 

 observed. 



As no distinct evidence of an increase either in the 

 muscular or nerve current was obtained, it has not 

 been thought necessary to particularize the results. 

 Great care was taken in all these experiments to 

 depolarize the platinum electrodes after the com- 

 pletion of each circuit, and to have them well 

 cleaned. 



In the next series of experiments, the current was 

 passed direct, so as to traverse the fibre in the con-
