as used in the preceding experiments, and phosphorus pentox- 

 ide was put into the eudiometers to dry the gases. The appa- 

 ratus was- allowed to stand for two days and then the glow 

 discharge was passed for two hours. The contraction in vol- 

 ume caused by the discharge was in each case 2*5 CC , reduced to 

 0° and 760 mm pressure. The initial volumes were 13'1 CC and 

 18*5 CC respectively. The results show that dry carbonic oxide 

 and oxygen slowly combine when acted upon by the glow dis- 

 charge. 



Methane and Oxygen. 



The methane was made from methyl iodide by the action of 

 zinc and alcohol. For the following experiments one volume 

 of methane and two volumes of oxygen were mixed over water. 





Hydrogen, 2 volumes. 







Methane, 1 volume. 







Oxygen, 1 "

The eudiometers in the first experiment contained 1*9 CC and 

 08 cc of air and the residual gases at the end of the test were 

 2*9 CC and 1*5 CC respectively when the battery gave out. The 

 result shows that the methane and oxygen combined according 

 to the equation 



CH 4 + 20 2 = C0 2 + 2H 2 0. 



In the second experiment the residual gas, after the discharge 

 ceased to cause a diminution of volume in the methane-oxygen 

 mixture, was 2*7 CC , while in the last experiment the residual gas
