Referee's report by Ronald Percy Bell, on a paper 'The theory of regular solutions' by John Shipley Rowlinson Sectional committee: Chemistry Paper reference code: A24 Bell writes: 'I can see that this paper probably represents a useful extension of the theory of solutions, but I find it very difficult reading, and am quite out of my depth in considering it critically. I think that it must be looked at by someone working in the same field: as Guggenheim is abroad I might suggest Lennard-Jones, Rushbrooke, Miller, Gee or McGlashen.'
