X-ray off-specular diffuse scattering is used to directly probe the statistical distribution of domains in monolayers of adsorbed at the hexane-water interface. These domains appear very near a transition from a monolayer solid to gas phase. The domains have a nearly constant radius of and a nearest-neighbor separation that varies from 2 to 8 with temperature. Evidence that the domains are of equilibrium size suggests that the domain line tension, , can be determined.
