Referee's report by John Desmond Bernal, on a paper 'Melting and crystal structure. The mechanism of melting of group I nitrates' by W J Davis, S E Rogers and Alfred Rene Jean Ubbelohde Sectional committee: Chemistry Paper reference code: A91 Recommended for publication in the Proceedings. Bernal comments the 'paper brings out the very interesting point of the lower entropy of melting of nitrates as compared with chlorides', however there is 'difficult to see any chemical basis for this', and includes a table.
