THE mode of representing the structure of the important class of the azoxy-compounds has recently undergone a change, based originally on chemical evidence provided by Angeli, and confirmed by the isolation of optically active substances by Marvel and E. Miiller. The new formulation is a consequence also of the physical properties of the substances. The present monograph sets out clearly and accurately the grounds for the present representation of the structure of the azoxy-compounds, with full references to the literature. It is a useful contribution to the literature on the organic chemistry of nitrogen.
