HATCH EXPERBn:XT STATION. 



[Ja 



In the two preceding tables are shown the results of elec- 

 trical treatment upon lettuce. The current was set at .2 

 millianiperes in experiments 23 and 26, and at A milliam- 

 peres in experiments 24 and 27. The experiments in both 

 tables show the effect of electrical treatment, and where the 

 resistance was modified the results are tolerably uniform. 

 The gain by all treatment is l().2y and 54.52 per cent, 

 respectively.
