EXPERIMENTS ON REFLEX ACTION. 



347 



During the experiment both frogs struggled a good deal, and 

 when a severe struggle occurred just before the acid was 

 applied to the foot reflex action seemed to be somewhat di- 

 minished. 



During the night they were taken down and had rested. 

 Experiment XIII. — Two frogs suspended, and reflex action 

 tested with sulphuric acid (1 to 250 water).
