2. li is clear that as far as the metastable and unstable eq\iilibria 

 are concerned, the pseudo 7'-.r-ügure will be different according as 

 one view or the other is held. 



The assumption of continuity in the unstable region would lead 

 to the T, ./'-ligures 5 and 6. 



In Fi"-. 6 the lines pd and me pass continnously into each other, 

 in the same way as in Fig. 5. 



The assumption of isodimorphy of the pseudo components, which 

 is less probable than the two following, yields the figures 7 and 8. 



The assumption of an asymptotic course of the $-,t'-lines leads to 

 the figures 9 and 10.
