/. Effect of the electric current. Weak induction currents have, 

 within a limited time, no noticeable effect upon the feeding, as 

 is shown by the following results from two separate experiments, 

 VIII and IX. The total number of grains eaten by 20 individ- 

 uals in each of two 8 cc. dishes is given in each experiment:^ 



Experiment VIII 

 Dish A — 73, total number of grains eaten by 20 individuals 

 Dish B — 69, total number of grains eaten by 20 individuals 



Experiment IX 

 Dish A — 65, total number of grains eaten by 20 individuals 

 Dish B — 64, total number of grains eaten by 20 individuals 



Control for Experiments VIII and IX; not stimulated by the 

 current 

 Dish C — 89, total number of grains eaten by 20 individuals 



8 The apparatus was arranged in such a way as completely to prevent any 

 effect of substances liberated at the electrodes, by inserting the electrodes in a 

 physiological normal NaCl solution in each of two 8 cc. dishes and from these 

 .the circuit was closed through the other two 8 cc. dishes containing the animals, 

 by means, of small n tube connections filled with tap water and plugged loosely 

 with a wad of cotton.
