    Abstract

    The extreme importance of correctly establishing the locus of separation in an adhering system, such as a film on a solid, is pointed out. Two theories as to the level of possibility that true interfacial separation will occur are described and both are criticized. A logically rigorous formulation which draws upon both these theories is given.
