connection with this thai all potential lines terminate in the point 

 v=b and x = l. M^ is infinitely large on the line v = b, and 

 on the second axis M\ii l is negative infinite. In the point v = b and 

 x = i the value of the potential for the first component must there- 

 fore be indefinite. When arriving at this point all potential lines 

 touch the line v = b. In fig. 15 the course of' the potential lines 

 has been schematically represented for this case of non-miscibility in 

 the liquid stale. The first axis is cul or touched by the potential
