(Sr) 
then (see fig. 1) v—=2b, lies on the right of v —=h,,and accordingly 
the solid phase not on the right but on the left of the liquid one. 
Not C and D, but D and Z will then coincide in an horizontal 
point of inflection (critical point solid-liquid). 
4. After the above digression we return again to the shape of the 
isotherm in fig. 1, and we shall carry out a simple computation 
to prove our statements. For this purpose we shall first modify the 
principal equations somewhat. 
If we put: 
we can write equation (2) in the form:

and the value of v can be calculated from:

So if we successively assume different values of » for given values 
of 4,7, 6,,-— Ab and 6(7'), we may calculate for each of them the 
corresponding values of 3, v and p, 
If we assume: 
e= 2(Gr. Cal.); 9, == 3200 (Gr. Cal.); b, =1; 26,—='/,; a= 2700,
