The quantities and relationships of capillary theory are summarized in a consistent formalism. Its constituents are the canonical thermostatics of the excess quantities, the interpretation of the surface tension according to deformation theory, and the formalism of parametric theory. A generalized concept of surface excess quantities is established by introducing the factors νφ and defining the individual quantities. The deformation quantities can also be incorporated into the theory, but the changes in the phase volumes have to be restricted. The theoretical difficulties of the traditional hypotheses do not arise in this unified approach and quantities that are not open to measurement can be calculated.
