In a recent number of this journal I advocated the systematic employment of a certain criterion in connexion with the classification and nomenclature of igneous rocks, that criterion being the ‘saturated’ or ‘unsaturated’ character of the minerals constituting a given rock. The terms saturated, unsaturated, and their derivatives oversaturated, undersaturated, and partsaturated, were not used in a strict chemical sense, but in a special mineralogical sense which was fully explained.
