SUMMARY OF PRECEDING RESULTS 
The average result of an 
immersion of five minutes 
duration in a normal 
(1 gramme equivalent mole- 
cule per litre) solution of 
Is to give a new value to 
the ' injury current,' which 
can be expressed as being 
equal to the initial value 
multiplied by the following 
factor 
This factor can be expressed 
also in the form given
