that the character of the transmission curve for alcohol is very similar 

 to that for water. 



Such depths of solutions were used that they contained in the one 

 cell 21 mm. of alcohol and in the other 1 mm. As with acetone, the 

 percentage transmissions for both the solution and the solvent are very 

 nearly the same. This was perhaps to be expected, since with water 

 the percentage transmissions of both solution and solvent are very
