Dr.  Gundry  on  the  Asymmetrical  Action  of  an 
due  to  self-induction  could  be  neglected  in  comparison  with 
the  total  resistance. 
The  experiments,  shown  in  the  following;  tables,  were  made 
with  normal  KCN  solution  without  any  direct-current  pola- 
rization. The  direct  current  observed  was  always  in  the 
direction  in  the  electrolyte  from  small  electrode  to  large. 
The  deflexions  of  the  galvanometer  are  shown  in  the  third 
column.  The  measurements  were  made  twice  for  each 
strength  of  alternating  current,  the  first  series  with  in- 
creasing current  and  the  second  with  decreasing  current  ; 
both  are  given  to  show*  the  constancy  of  the  effect.  In  the 
fourth  column   the   direct  current   I    is    obtained  from  the 
mean  of  the  two  deflexions.     In  the  last  column  — ,  is  shown 
with  the  mean  of  the  values  given.  l° 
The  value  of  the  external  resistance  W  was  100,000  ohms.
