MUNROE-HOWELL— PRODUCTS OF DETONATION OF TNT. 223 



A careful examination of the pressure reading on the water 

 manometer, analysis of the second sample of gas, and the analysis 

 and amount of gases retained in the solid products shows that the 

 amount of gas retained by the solid products is not sufficient to have 

 any important effect on the observed pressure reading or analysis 

 of the gases. 



Our thanks are due to Messrs. W. L. Parker, L. B. Berger and 

 W. H. Miller for the analyses of the gaseous products ; to L. G. 

 Marsh, Assistant Explosives Chemist, for the analyses of TNT, to 

 Mr. A. B. Coates and his associates of the Explosives Experiment 

 Station, and especially to Mr. J. E. Crawshaw, Explosives Testing 

 Engineer, who, during the enforced absence of one of us owing to 

 sickness, has taken entire charge of the operations.
