SIR ANDREW NOBLE: RESEARCHES ON EXPLOSIVES. 



If the column of weights be added up, it will be found that there is a deficiency of 

 6 '3 5 grammes. The quantity of gas measured must therefore be increased to 

 97,158-9 cub. centims., and the corrected calculation will stand thus: 



RECONCILIATION.

The heat units evolved by the explosion were, as has been already mentioned, 

 determined in a calorimeter of the type of that described by Professor OSTWALD in 

 his " Physico-Chemical Measurements."
