one square with respect to each other. The origin of each curve is 

 so situated that at 12000 kgm. the compressibility has approached 

 to within less than one unit of zero. Thus, the compressibility of 

 ethyl alcohol at 12000 is O.O58I. 



The most striking feature is that the curves become nearly equi- 

 spaced at the higher pressures. This appearance of increasing equality 

 of behavior is not an illusion due to the approach of all the curves to
