Values of the limiting specific volumev0calculated by a trial‐and‐error procedure fromn‐alkane viscosity data using the author's free‐space viscosity equation,ln&eegr;=B(v0/vf)+lnA,agree substantially with previously published values obtained by extrapolation of density data. Values ofv0for mercury, sodium, benzene, carbon tetrachloride, dichlorodifluoromethane, and water were calculated by the same trial‐and‐error procedure. In all cases the free‐space equation gave a much better fit than the corresponding Andrade temperature equation,ln&eegr;=B/T+lnA.
