locomotor limbs are involved in the earhtworm's reaction its 

 response accords in as simple a way as possible with Loeb's 

 theory of galvanotropism. We may therefore conclude that the 

 constant current produces the effects described by increasing 

 the tension of the longitudinal muscles on the kathodal side of 

 the worm, w r hich results in this part being more strongly con- 

 tracted than the anoclal region.
