about 0"0002 amperes. The continuance of this small 

 current for about five minutes was found to be quite 

 sufficient to give rise to a polarisation of about 0"85 volt. 

 It would therefore seem probable that a polarisation 

 of 5 to 6 volts may be attained with higher current

 method are given. 



Our observations confirm those of Chanoz^ who 

 obtained a maximum polarisation of about 075 volts for
