3. Cyanogen with Nitrous Oxide and Nitrogen. 



4. Cyanogen with Nitric Oxide. 



The formula that I have given was thus found to agree 

 with all the cyanogen explosions. It is therefore, at all 

 events, an empirical expression which can be applied to 

 calculate the rates of explosion of cyanogen burning to 

 carbonic oxide and nitrogen under a fairly wide range of 

 •conditions. It was accordingly a matter of considerable 

 interest to apply the formula to the rates found when 

 electrolytic gas was exploded by itself and when diluted 

 with hydrogen, oxygen, and nitrogen. In the following 

 table the rates for electrolytic gas with excess of hydrogen 

 and of oxygen are compared with the numbers calculated 

 from Berthelot's formula (0), and with the sound wave (S) 

 calculated as before.
