In the foregoing tables the values of the decrement in Table I 

 were obtained for the liquid side at 195-9° on the rising part of the 

 curve. The temperature was raised to 240° and lowered as quickly 

 as possible to 196-2° and the readings for Table V were made. The 

 temperature was then lowered to 194-9° and the readings for Table 

 VI taken. The temperature was then lowered to 194- 1° and the ob- 

 servations for Table VII were taken.

Tables II, IV and VII are for temperatures below the critical 

 point shown by the salient point on Figure 9. The following tables, 

 VIII and IX are for still lower temperatures.
