by a potential difference of 1.4 volt. For this purpose two brass 

 plates serving as electrodes for the current, had been sunk in the 

 cork sub-stratum of the muscle, whilst by means of a commutator 

 the direction of the current can be changed. At the beginning of the 

 experiment the anode is found at the distal tendon; afterwards the 

 current is turned and ends in its original direction. In the subjoined 

 table occur the widths of the first 4 reflections in mM. 



The following table gives the difference between the M. sartorius 

 of Rana temporaria through which a galvanic current has passed 

 and another through which it has not passed.

That abundant moistening of a muscle with mutually equimolecular 

 salt-solutions, the effect of which on the autotonus is antagonistic, 

 can alter the hardness, appears from wiiat follows, also holding good 

 for the M. sartorius of Rana temporaria.
