Phenomena of some Suhstances and Mixtures. 187 



The figures are therefoi*e less trustworthy than those for N 2 0- 

 C 2 H 6 or those for C0 2 -0 2 H 6 , the combination to be described 

 presently. 



The v-x curves have the same character as those for 

 N 2 0— C 2 H e : it seems therefore unnecessary to publish them. 



D. Mixtures of Carbonic Acid and Ethane. 

 23. The ethane used in these experiments was the same as 

 for the mixtures with acetylene. The carbonic acid was taken 

 from an ordinary carbonic-acid cylinder, after having been 

 distilled and purified in a small high-pressure cylinder in the 

 way as described for ethane (see § 5).
