SIR ANDREW NOBLE: RESEARCHES ON EXPLOSIVES. 



211 



Again, with a charge of 99 '65 grammes of M.D. cordite and a density of 0'3, the 

 gaseous pressure being 27'62 tons per sq. inch (4210'3 atmospheres), the quantity 

 of gas measured, after being reduced to C. and 760 millims. pressure, was 

 72,768 cub. centims., while the quantity of water collected was 11 '162 grammes, 

 equals 13,885'5 cub. centims. aqueous vapour at C. and 760 millims. pressure. 



From the above data it appears that the explosion gave rise to 735 cub. centims. 

 of permanent gas and 87 5 '3 cub. centims. total gas when reduced to C. and 

 760 millims. pressure.
