v= 26, (liquid), which gives rise to the coexistence solid-liquid. In 
other words there is no value of 4b for which a coexistence-curve 
solid-liquid will occur. 
This is immediately seen, when we e.g. assume g, == 3200, as in 
our former example for Ad negative.

This agrees entirely with the preceding form, except that now

in fig. 22), viz. = — 2,077; while at p= 10-7® the value of log’

Even at 7’= 100, in consequence of which

the portion AZ evidently lies between p= 10 and 10-®, 1e. v 
between 50 and 10° (in the first case 3 is namely = 0, in the second

Not before 7’= 200 the change of 8 from O to 1 would be found 
between values of v which might deserve consideration — but then 
we have already arrived above the critical temperature vapour-liquid, 
which lies at 133° for Ab = 0,5. 
So we are obliged to lower the value of g, in such a way that
