  A method of obtaining the critical temperature from within a supercritical
mesophase bounded by percolation transition loci is described. We report
thermodynamic pressures from MD simulations for more than 2000 state points
along 7 near-critical isotherms of a Lennard-Jones fluid. Direct evaluation of
Gibbs chemical potential along the critical isotherm reaffirms the existence of
a supercritical mesophaseand a line of critical states and non-existence of van
der Waals critical point.
