398 EXPLOSIVE GASES AND DETONATING GASEOUS MIXTURES. 



1 This volume ought really to be multiplied by (1 + a to render the 

 water actually gaseous at t. 



2 One grm. in n cubic centimetres ; water liquid. These figures are only valid 

 when is sufficiently large for the carbonic acid not to be liquefied, or in the case 

 of carbon dlsulphide, the sulphurous acid. 



3 Favre found the heat of liquefaction of N 2 = 44 grms. to be = 4'4 Cal. 

 This figure has been taken for the other liquefied gases. 



4 Nitric peroxide is incompatible either with ethylene or benzene. 



5 Turpin employed barely half the proportion of nitric peroxide indicated 

 here; this gave rise to incomplete combustion with deposition of sulphur.
