section lies on the spinodai line. Then a point of the left-hand side 

 of the spinodai line coincides with a point of the right-hand side of 

 this line, but not in the hidden plaitpoint. Consult also fig. 17 

 (These Proc. May 24, 1907 p. 68). Then there are 4 plaitpoints, 

 viz. P l , P„ and the double plaitpoint in the splitting point of the 

 spinodai line. The course of the binodal curve on the liquid side has 

 been represented in fig. 26. On the liquid side the binodal curve of

the vapour-liquid equilibria passes in two more points, y and tf, through 

 the spinodai curve. And so nothing appears vet of the detaching of 

 the longitudinal plait for the experiment. Only at higher temperature 

 the detached binodal curve, and then with its newly obtained plait- 

 point, will pass through the binodal curve AB, and with still higher 

 value of T the binodal line has split up into two quite separate 

 branches.
