The numbers in the third column are those given by the equation 
10 4 £ = 
(41 + 3c). 
In Section III. the relative conductivities of several sodium chloride solutions are 
given. The following table gives numbers calculated from those results taking 
c = 30’3 when k = 20 gr. per litre. The value c = 30‘3 when k = 20 was got from 
the relative conductivities found for csesium and sodium salts :—
