Paper, 'The molecular surface-energy of mixtures of non-associating liquids' by William Ramsay and Emily Aston The authors write: 'It has been shown in the previous paper [see PP/24/14] that it is possible to calculate the degree of association of an associating liquid such as alcohol, on the assumption that molecules of less complexity remain uniformly distributed along with molecules of greater complexity throughout the liquid, and that no one kind of molecule tends to congregate on the surface to the exclusion of the other.'
