The n'snits for niethylalcohol and ethane are laid dow n in liuiire 2. 

 I can ui\t' oidy a short explanation here. Slartiniz from ( '., the 



(•rilical poim of methy lalcohol the critical cnrvc runs in a per- 



fectly normal way at lii'st. ow inii' to the inilnence of the association 

 heiiiii' as yet insulTuMent. it ascends, passes throuiih a maximiini 

 at 120 . and then falls, evidently teji<Uiig towards the critical point
