If the values of v a in Table XIX be compared for the 

 same concentration of solute, the variation of the specific 

 solution volume with the composition of the solvent is 

 more clearly shown. The values of v 8 for A = 6 are 

 given below, together with the specific contraction observed 

 in the preparation of each of the solvents.
