Fig. 3 (p. 186) represents a case in which the vapour and 

 one of tbe liquids have a critical point. This is the complete 

 solubility-curve for ether and water, as will appear from the 

 measurements given in this paper. Here the water and 

 ether branch stops abruptly at the temperature (201° C.) at 

 which the upper liquid and the vapour reach their critical 

 point. The composition of the vapour is between the com- 

 positions of the liquids, and accordingly the three-phase
