102 STUDIES IN ELECTRO-PHYSIOLOGY: 

 The actual connections in my original tests were :

dj was taken with a standard condenser of 1 microfarad 

 capacity, a galvanometer resistance of 7,000, and a shunt 

 of 80 ohms. The immediate discharge, or d l9 was 204 mm., 



or, multiplied by - - = 18,033-6 mm. ; while <Z 2 , with 

 s 



a 80-ohm shunt, was 290 mm., or 67,947 mm. in full. This 

 by the formula F 2 = F j gave 376 micros (nearly) as 



the capacity of the body. In taking this test it is advisable 

 that the observer stands as far from the subject as 

 possible.
