The majority of the organic compounds (table IIT) follow 
Ramsay's and Young's simpler formula with considerable 
accuracy. Of the 31 organic compounds in the table only 
etylalcohol, metylalcohol and acetic acid show considerable 
differences from the calculated values, (compare page 3). 
A great number of the remaining 28 substances exhibit 
differences of less than 5 24 at 30 atmospheres and none 
of these differences exceed 10 96. 
Somewhat greater differences between observed and 
calculated values are to be found among the inorganic com- 
pounds (table IT). The boiling point of water is at 30 at- 
mospheres not less than 47” or 35 2 below the calculated 
1) The boiling point at 1 atm. is extrapolated to 240".
