Experimental Results. 



In the following tables 



>] is the viscosity, expressed in absolute units, of water at the given temperature. 



The values of % are taken from Thorpe and Rodger's determinations.* 

 m is the concentration of the solution in mols per litre. 

 d is the density of the solution referred to water at 4°. 

 >j/i] is the ratio of the viscosity of the solution to that of the solvent at the given 



temperature, as directly determined by experiment. 

 n is the viscosity of the solutions in absolute units, and is obtained from the ratio 



given in the third column by multiplication with the value of % given at the 



head of the table.
