Experiment 1496. At a density of 0'5 a charge of 155 "84 grammes of cordite 

 were fired under a pressure of 52 '84 tons per sq. inch (80547 atmospheres). On 

 firing, a slight escape of gas passed the firing plug, which, however, became 

 immediately tight. The quantity of gas measured was 93,1 99 - 8 cub. centims., when 

 reduced to C. and 760 millims. pressure. 21 '135 grammes of water were collected, 

 representing 26,291 cub. centims. aqueous vapour. At the standard temperature 

 and pressure, the gas analysis was as follows :
