For a somewhat higher tempcratnre the diagram is a little ditrerent, 

 because now the vapour- and liquid curve continuously pass into 

 each other with a critical point in <(„ the vapour-line </,r^ being- 

 shorter than at the former temperature. At rise of temperature this 

 vapoitr-line cotitinually decreases in length, until at the melting poitit 

 of B in the point cl it has disappeared altogether. Above the melting 

 point a saturated solution is no longer possible and so there we 

 get only a lifpiid- and a vapour-line with a critical point in n^. If 

 we draw a line through the points a, a,, <i^, n^ and J>, a second 

 through the points c, c„ c, and d and a third through the points
