den and so also 7., must be capable of having a minimum. In 
this way we arrive therefore for a ternary system at the same 
result, as I had formerly obtained for a binary system, also for the 
limiting case of low temperatures. 
If we do not consider the limiting case, which would correspond 
with 7=0, but if we give 7’ a definite value, we find: 
from which follows that for the maximum pressure at temperature 
=T the values of « and y are found from the two following 
equations 
and
