The characters of the vigorous response are given by the above readings; and by 
taking the deflections as ordinates, and the times of closure as abscissae, a curve may be 
Fig. 3. 
The numbers 
100, 200, 300, 
&c. Indicate seal e 
of Galvanometer. 
The numbers 10, 
20, 30, 40, &c., 
correspond to 
thousandths of 
seconds; 0 re¬ 
presenting the 
moment of nerve 
excitation. 
The transmis¬

the rapid rise and slower decline of the electromotive change. In the figure 
the curve a is that of a preparation made from a large vigorous Torpedo, b is that
