in which To. etc. are the boiling points of the pure chemical

 by the same, we have

for the equation representing the relation between the boiling 

 point and the composition. This equation can indeed be employed 

 for the calculation of the boiling point, but it is too complex 

 for general discussion. Hence the study of the boiHng point is 

 not so well fitted for elucidating the chemical conditions of the
