Referee's report by Robert Howson Pickard, on a paper 'Studies of co-ordination.—Part II. absorption spectra of metallic derivatives of benzoylcamphor' by Thomas Martin Lowry, Henry Burgess, Ivor John Faulkner and Ralph C Traill Sectional committee: Chemistry Recommended for publication in Proceedings. The paper is purely chemical and therefore publishing it in Proceedings will be inconvenient to other chemists. It should be published in the Journal of the Chemical Society instead.
