Conclusions 1. A system has been developed for measuring the force of interaction between surfaces in solutions, and the variation of this force with the distance of surface separation. 2. At distances of separation of 5 nm or less the measured forces of repulsion between glass and quartz surfaces in KCl solution do not agree with the values calculated from DLVO theory, the difference here being ascribed to the existence of a structural component of the disjoining pressure. At greater distances of separation, the measured force falls off exponentially with an increase in H, being covered by an exponential equation with Ho-0.85 nm. 3. The fact that the force of adhesion between glass and quartz fibers is low, or even equal to zero, can be ascribed to the action of structural forces of repulsion. In the case of mica, such forces appear at both high and low KCl concentrations, the situation being different in this respect from that met with quartz and glass.
