EXPLOSIVE COMPOUND. 



with chlorine, action of that portion on ammonia. This portion of chlorine 

 nnanth Cl1 stat* would not > therefore, be indicated in the action of the corn- 

 ed, pound on ammonia by the separation of one-third its volume 

 of azotic gas, it having combined with hydrogen at the expence 

 of the compound, and not at the expence of the ammonia. 

 In the before-mentioned analysis there xs, therefore, a deficiency 

 of a certain portion of hydrogen, and of a certain portion of 

 chlorine j but, as the total deficiency of both is known, (being 

 the difference between the weighi of the compound analysed, 

 •625 of a grain, and that of the gases ascertained by the ana- 

 lysis, *4459 of a grain) viz. *1 /Ql of a grain ; and as the pro- 

 portions in which chlorine combines with hydrogen are also 

 known, (being equal volumes of the two gases, or by weight 

 J hydrogen to 30" 148 chlorine) it follows, that the volumes and 

 weights to be added are,
