If in fig-. 3 the number of Molec. aniline on 100 Molec. Phenol 

 + aniline is indicated again on the X-axis, and on the F-axis the 

 mixingteinperature, we get a line ghk as is drawn in fig. 3 which: 

 1" starts from j/ to a higher temperature, 2" touches the line de 

 3" reaches its maximum temperature in h and 4^ furthei' on bends 

 down to lower temperatures. 



The preceding line ghk is for a mixture containing 10.9 pCt. 

 Phenol and 89.1 pCt. water; for mixtures of other compositions wc 

 also get other lines. F. i. if we take a mixture of 63.7 pCt. phenol 

 and 36.3 pCt. water, it has just like the former its mixingtem- 

 perature at ± 46°. When adding aniline we then get the following:

These values are indicated in fig. 3 by glm^ which like ghk 

 begins at g. reaches its maximum temperature at ^, and then bends 

 down to lower temperatures.
