Separation of Three Liquids by Fractional Distillation. 15 



It is to be noted that in II. a, which is richest in the low- 

 boiling liquid A, the amount of A rises from *543 to an initial 

 value '74, and in the first half (or at least §) of the distillate 

 the aggregate amount of A rises to "7. 



In II. e, which is richest in the high-boiling liquid 0, the 

 amount of C rises from *687 to about *9 in the last fifth, or 

 •82 in the last two-fifths of the distillate ; whereas in II. 8,

which is richest in B, the middle liquid, the amount of B 

 rises merely from *39, its initial value, to about '45, its value 

 for the fifth which is collected just after the first half ("5 to 

 •7). It is curious that in each of these distillations B rises to
