PHENOMENA OF MUSCLE AND NERVE.

In the tables the letters a and c indicate that the deflection to the record of which 

 they are appended belongs to the muscle to which the anode and kathode are respec- 

 tively applied. The capital letters A and C indicate that the region led off was in 

 the neighbourhood of the physiological anode and kathode respectively. In the 

 preceding experiments the physiological and actual anodes and kathodes were identical. 

 This is not the case in the following ones. 



Example. Sartorius muscles attached to the symphysis. Leading- 

 in electrodes at the two knee-ends A and B. Both muscles led off 

 in the neighbourhood of the symphysis at cc' and dd'. The schema 

 gives the intervals

The galvanometers used were the same as in the previous experiments, and, as is 

 evident, the remarks as to the differences between their deflections apply here. (The 

 readings in cc' were taken by Herr v. Gendre with the Wiedemann, those in dd' by 

 myself with my galvanometer.)
