liquid with the rim join, then they are detached from the rim, and 

 we get, therefore, in this ease, but only above T A , so above tempe- 

 rature A of fig. 1, the continuous line drawn by Smits fig. 3 (loc. 

 cit.), which then passes into figs 4 and 5 (loc. cit.). 



The case mentioned under 2 that the point of contraction falls 

 outside the figure may after all, be derived from the foregoing by 

 putting' T h , the temperature at which the detached branch disappears 

 from the figure, below 1\, the temperature at which it detaches 

 itself from the rim. In our figures it has only this influence that the 

 loop of figs. 9 and 10a cannot detach itself from the rim, as in 

 fig. JO, and disappear as isolated point; but this loop contracts more 

 and more at the rim and disappears there. In this case, too, 1\ can 

 lie above T z , but of course, not above 1\. If r l\ lies under T 3 , we 

 have the succession 6, 7, 8, 9 and disappearance of the loop in the 

 rim; if r l\ lies above T t then: 6, 9a, 10a, 11, and disappearance 

 of the loop in the rim. 



The above case mentioned under 1, when also the point of detach- 

 ment falls outside the v, «-figure, may be considered as the case that 

 r J\ lies below 1\, and 1\ above 1\. We have then the succession, 

 the upper portion of fig. 6 (viz. without the downmost loop), figs. 

 12, 8, 9, after which the loop merges in the rim. Now in all the 

 cases mentioned, except in the second subdivision of the case under 

 3 (so T„ above T z ), we meet still with two possibilities. Up to now 

 we have assumed for those cases, that the triple point temperature 

 is the highest temperature at which the two binodal curves intersect in 

 the stable region, and that they have got detached above it. It is now, 

 however, possible, that also in these cases the two binodals intersect 

 twice at the triple point and above it. Then fig. 96, is put every- 

 where for fig. 9, and then this is changed into fig. 11. 



We get then the following summary ;
