EFFECTS OF PRESSURE ON NITRATES.

the highest Av points. There are enough high points for each transi- 

 tion to determine a pretty good Hne, and considering that practically 

 all sources of error conspire to give a value of Av too low, there is 

 considerable probability that the values adopted are near the truth.

The lat'mt heat and the change of energy, calculated with the 

 values found above from the curves of t and Av against pressure are 

 shown in Figure 9. The three modifications behave differently with
