motive force of the semi-membrauous muscle was found in several 

 instances to amount to as much as the j\ih. of a Daniell or 0*1 D. 

 The deflection of the magnet due to the electrical current of the 

 sciatic nerve corresponded on an average to 21 divisions of the scale, 

 the electro-motive force giving rise to it to the ^th of a Daniell or 

 0*0237 D. a result agreeing closely with that of Du Bois Reymond^ 

 viz : — 0'022 D. In conclusion it is worthy of observation that the 

 electro-motive of the muscle is more than three times as great as that 

 of the nerve.
