Experiment (Tap Water) 
(Fig. W) 
A is the curve of distribution 
of potential upon the nerve when 
removed from the bod)'. It will be 
seen that, in all essential details, it is 
similar to the curves given in the 
preceding section upon the ' current 
of injur}".' 
C is the curve of distribution of 
potential after the immersion of the 
nerve in tap water (p. 277). The 
point of reference was in this case,, 
the upper cross section. 
B is the similar curve obtained 
later (it is, therefore, lower). The 
point of reference in this case was 
the lower cross section (p. 278). 
Attention ^is drawn to the posi- 
tion of the maximum point in each of 
the three curves A, B, C.
