A curve was drawn to represent these relations ; and from 

 it three points were chosen, viz. 0°, 40°, and 80°; the corre- 

 sponding pressures are: 0°, 25*54 millim. ; 40°, 180*2 millim.; 

 and 80°, 755*0 millim. The constants for the formula 

 p — a + ba* are 



a = 4*72452; log 6 = 0*5185950 ; log*=l-996847125; 



b is negative. 



The following Table shows the calculated vapour-pressure 

 for each 10°.
