IT. Alcohol. — The alcohol used was the commercial absolute 

 spirit. Table 6 contains the observations for compressibility. 

 All observations are referred to 150 atm., for the tube was not 

 long enough for observations corresponding to lower initial 

 pressures. Thermal expansions are given in table 7.
