  The Sutherland approximation to the van der Waals forces is applied to the
derivation of a self-consistent Vlasov-type field in a liquid filling a half
space, bordering vacuum. The ensuing Vlasov equation is then derived, and
solved to predict the behavior of the density at and in the vicinity of the
liquid-vacuum interface. A numerical solution to the Vlasov equation is also
produced and the density profile shown and discussed.
