Two values are given for 10 millim.: — (a) the ratio calcu- 

 lated from Regnault's values, and (b) the ratio obtained by em- 

 ploying the recalculated temperature of ethyl alcohol. The only 

 noticeable difference between the observed and recalculated 

 temperatures is at a pressure of 10 millim.; and by taking the 

 recalculated temperature of ethyl alcohol it is greatly reduced.
