§ 11. Carbon Dioxide (CO). 
The gas was prepared from marble and hydrochloric acid. It was purified by being 
washed with water and passed over bicarbonate of potash and calcium chloride. 
REGNAULT’s value, 1°529, was taken as the specific gravity of the gas. 
: : . 1d — 
The experiments of ANDREWS afford material for calculating the term 1 + rr = pu. 
Using the results as tabulated by Lanpour and Bornstein (2nd edition, p. 83), the 
term has the value 1:007 for atmospheric pressure and temperatures between 
0° and 30°. 
The following table gives the results of the experiments, the pressure of the gas 
being in each case that of the atmosphere.
