T ABLE IV. 

 Mixture .r= 0,1990. Isothermal Hues. 



For the three mixtures the volumes and the pressures at the be- 

 ginning and the end of the condensation were read on the p-v-t dia- 

 grams, constructed by means of the data in the tables I, III and IV, 

 and of which only one was given in the previous communication ; these 

 volumes and pressures are given in table V. Only for x = 0,0494 

 the end of the condensation was observed for temperatures at some 

 distance from the critical point of contact; for ;r = 0,0995 the 

 increase of pressure during the CDndousation was so great that for 

 temperatures a little below the plaitpoint-temperature observations of 

 the end of the condensation could not be made. In the case of the 

 mixture o? =: 0,1990 no observations could be made on the liquid- 

 branch of the border-curve.
