A maximum has appearel at D and a minimum at C, but no 
coexistence pressure as yet, because the pressure-curve about halfway 
E and D (p= += — 250) still runs below C. (Fig. 29).

The coexistence-pressure liquid-solid is about — 125; and it is 
real, because now — 125 is greater than the pressure in C. Hence 
the case of fig. 29 lies between 60° and 65°. By interpolation we 
easily calculate that the pressure of coexistence (fig. 29) first makes 
its appearance at 62°, where then p=pg is about = —200. 
Now this pressure is real, but still unrealisable as negative pressure.
