Abstract
THE discussion on this subject arranged by the Faraday Society excited great interest, and the collected papers contain much that is of value. Whilst most of the speakers dealt with heterogeneous equilibria, and particularly with the crystallisation of minerals from magmas, one rather elaborate memoir on homogeneous equilibria was communicated by Prof. Niggli, of Zurich, in which certain considerations relating to the formation and decomposition of compounds in solution are applied to rock provinces of the Pacific, Mediterranean, and Atlantic types, a diagram being used to indicate the relationships, in such a way as to point to the differentiations which may be expected to occur during cooling.
