Abstract
The significance of Harkins and Wampler's data on the surface tension of aqueous solutions of n-butyl alcohol is reconsidered. The surface layer does not tend to form a complete monolayer of butyl alcohol molecules, but approximates to a 1 1 ratio of alcohol and water molecules at high relative concentrations. Individual adsorption isotherms are drawn for solute and solvent and compared with those for aqueous solutions of the normal alcohols up to octanol.
