96 THE SIGNS OF LIFE [LECT. v. 



60. Exposed muscle has given precisely the same formula 

 as that of vegetables, i.e., ingoing effects at both poles ; while 

 dead muscle gave only the small antidrome deflections due to 

 ordinary polarisation. 



A frog's sciatic nerve gave responses homodrome with ex- 

 citation, larger on the anodic than on the kathodic side. But a 

 detailed examination of blaze-currents in nerve and in muscle 

 still remains to be made.
