miglit then be derived. Tliis inveyligatioii, in which also the mixtures 

 which had previously been investigated dynamically were veritied, 

 yielded the following result. 



The following mixtures were examined. 



the results of which are expressed in fig. 2. 



These vapour pressure lines enable ns to read the corresponding 

 boiling temperature for a definite pressnre (see table I), hence to 

 indicate the boiling-point lines, and that with an accuracy down to 

 tenths of degrees, and it is also possible to indicate the vapour 

 tension of different mixtures for a definite temperature (see table II), 

 hence to find the (/u')7' -lines with an accnracy of ±0,5 m.m. Hg. 



Fig. 3 contains the boiling-point curves, from which it appears
