will probably often be found when the critical temperatures 

 of the two components differ largely.

 condensation. At the last 

 three temperatures the sur- 



r face between the two phases 

 was faint; and there were 

 indications of critical phe- 



i nomena.

Mixtures of ethane and ether were tried, but three phases 

 were never obtained, the two liquid components mixing in all 

 proportions. Ethane and water do not mix in all proportions, 

 Measurements showed that for this combination (Table XV.)
