Also in the figures 24, 25, and 26 these stages are passed through 
in quite the same succession; only everything is more compressed 
then, that is, the distance between the points P and Cr becomes 
smaller and smaller, and the coexistence-curve will at last quite 
disappear from the field (fig. 26). 
Let us now calculate 7’— 50 for Ab —0,5 (fig. 28). The value 
25 
of 2 (ef. the formula (c)) is = 32. Further 9 is a so that (d) 
passes into

Then the values of » are calculated from (e), i. e.:

This gives the following survey.

So the temperature of the point of inflection D,C lies somewhat 
above 50°, viz. at 7’ = 52,3 (pp >= — 282).
