24 Mr. W. Sutherland on Weak Electrolytes and 



Table I. 



Contraction on making one gramme of mixture of Ethyl 



Alcohol and Water at 15° C. Alcohol as liquid 1, water 



as liquid 2, ^ = 079356, p 2 = 0-999216. 100^ is the 

 percentage of alcohol by weight.

On account of their typical importance the data of this 

 table have been given in great detail, especially near the 

 decisive values of p lf where the mixture is a dilute solution 

 of alcohol in water, or of water in alcohol, or where p 1 is 

 nearly 0*5 and A is close to its maximum. The densities are
