While the paper is worthwhile, it does not significantly develop knowledge. Suggests a much shortened version of the paper be published, but thinks it would be best to consult other referees. Recommends [Frederick George] Donnan and [Edward Armand] Guggenheim for this. [Not published]. Received 12 July 1938 [July 1938]
