    • Friedman and Larsen [11(b)] report this graphically as what appears to be a sharply pointed ``marlin spike'' (with ρliq> ρvap> ρc for all T < Tc) instead of the correct rounded form shown in Fig. 2. Reference [10(c)] reproduces this marlin-spike shape but with a misplaced critical density.

    • One might also argue that a in the DH theory should be replaced by a1; but see [2(b),11(b),15].
