The values of M shown in table 37 

 are plotted as curves in fig. 19. The 

 results are of the same character as 

 those shown by the preceding mix- 

 tures. The most concentrated solu- 

 tion measured shows a somewhat 

 lower value for M in the mixture 

 than we should expect, but it must be 

 borne in mind that at this great con- 

 centration the experimental errors 

 involved are necessarily very large. 



Table 38 contains the data neces- 

 sary to compare the change in the 

 amount of solvent present with the 

 change in the values of M in sepa- 

 rate solution and in the mixture.
