The resulting calculated boiling points were entered into 
a table similar to table I whereupon these were compared 
with the actual boiling points under different pressures. The 
difference between the calculated and the observed boiling 
points were computed and the differences corresponding to 
5, 10, 20 — — — atmospheres interpolated from these values. 
In the table we find entered also the differences in degrees 
between the boiling point under normal pressure and: the 
boiling point corresponding to a pressure of 10 atmospheres 
and the difference between the normal boiling point and the 
boiling point under 30 or 90 atmospheres. The differences 
between the actual and the calculated boiling: points at 
10, 20 — — — atmospheres were calculated and expressed 
in percent of the total difference between the boiling points 
at the normal and at higher pressures mentioned. For every 
substance a table, like table I was compiled and the resulting 
numbers for the different investigated substances were 
brought together into tables II and III.
