Our first experiment with methyl alcohol made us think 

 that it mixed with ethane in all proportions (Table III.). 

 After expelling some of the alcohol, however, we obtained 

 two liquid layers at all temperatures up to the critical tem- 

 perature of the ethane layer and the vapour (Table IV.).
