Laplace does not treat systematically the question of interfacial tension, but he gives incidentally in terms of his quantity H a relation analogous to (47).

The different species of mica have very nearly the same forms and interfacial angles, and they not infrequently occur intergrown together in parallel position.

If T12 denote the interfacial tension, the energy corresponding to unit of area of the interface b Q FIG.

The problem is to make the sum of the interfacial tensions a minimum, each tension being proportional to the square of the difference of densities of the two contiguous liquids in question.
