Referee's report by John Edward Lennard-Jones, on a paper 'The van der Waals potential and the lattice energy of a n — CH2 chain molecule in a paraffin crystal' by Alex Müller Sectional committee: Physics Won't comment on publication until the author replies to his observations. The subject is interesting and important, but the theory isn't sufficiently advanced enough to apply it in a quantitative way. He is disturbed by the approximations used.
