SOLUTIONS OF POTASSIUM CHLORIDE 
Special Examination of the Action of Solutions of Potassium Chloride 
The action of solutions of the concentration of one gramme equivalent molecule 
per litre (7*45 grammes per cent.) has already been completely examined (see p. 316), 
the average result being 
Eco = Ea log 1-42. 
This relation differently expressed being 
Eto = Ea log — 
° n 
where ' n ' represents the concentration in gramme molecules per litre of the 
dissociated portion or electrolyte (*68). 
The following results, with this, cover an examination of a sufficiently wide 
range of concentrations, from 7-45 grammes per cent, to o*i 8 grammes per cent. 
The experimental method followed is precisely that previously detailed, and 
each observation recorded is from an individual sciatic nerve (cat) used for this 
observation (injury current before and after immersion in the given solution) and 
for no other.
