Mixtures of Ethane and Nitrous Oxide. 



181 



Results obtained with the Mixtures, 



21. The number of mixtures investigated was five. The 

 composition (x parts of ethane in the volume in the gaseous 

 state at one atmosphere) amounted to 0*18, 0*25, 0*43, 0*55, 

 0*76 respectively. The pressure and volume at the beginning 

 and at the end of the condensation as observed at different 

 temperatures are given in Tables I.-Y1I. The values of 

 the volumes are only approximate. They are expressed in 

 parts of the volume at 1 atm. and 0° C. For N 2 and C 2 H 6 

 only one value for the pressures has been given. Tables 

 V1II.-X. give the volumes for the temperatures 20°, 25°, 

 and 26° 0., as determined by graphical interpolation from 

 the values observed.
