TABLE OF RESULTS OF ELECTRICAL STIMULATION OF THE 

 ANTAGONISTIC MUSCLES OF THE FROG's LEG WITH CHANGING 

 RATES AND INTENSITIES. 



This table is selected from a series, as representative of the 

 usual response of the leg musculature to changing rates and in- 

 tensities. 



The following is a table of the results of some of the experi- 

 ments. It shows the intensity required with a given rate to 

 convert a flexion into an extension. Each experiment here 

 given is taken from a fresh Frog and represents the series 

 made on that individual.
