The object of the above experiments has been to determine the- 

 effect of diflferent forms of electric current upon germinal ion. Id 

 order that more accurate conclusions may be drawn, an average has- 

 been taken of the various results under each foini of treatment. 

 The following table gives a summary of these results : 



Average number of seeds germinated and the gain per cent by 

 treatment in Tables XII —XVII.
