1814.] Constituents of Azote. 269 



Having proceeded thus far, we will now show how the results of 

 experiment correspond with those ascertained by calculation in the 

 foregoing table. 



It will be remembered that experiment indicated the presence of 

 4242 per cent, of condensed hydrogen in the mixed gas. It has 

 been calculated that there exists 27*731 i n the acid gas, and 153 

 combined with it = 43*031 — a quantity agreeing with the above as 

 well as the uncertainty of the data could lead us to expect. 



The results of the action of the mixed gas on various solutions 

 exhibit proofs of its constitution according to the foregoing calcula- 

 tions: — 



Acetate of iron absorbed 34*78 per cent. ; hydrogen in the 

 residuum amounting per cent, of the mixed gas to 29*89. Henc« 

 the mued gas is composed of 



Acid gas 48*25 



Hydrogen 1 6*42 



Azote 35-33 



100* 



Muriate of bismuth absorbed per cent., 33*77 ' hydrogen libe- 

 rated, 30*46 : — 



Acid gas , 47*4/ 



Hydrogen 1 6*76' 



Azote 35*77 



Prussiate of mercury absorbed per cent., 56*86 * hydrogen libe- 

 rated, 13*17 : — 



Acid gas 62*79 



Hydiogen 7'24 



Azote 29*97 



The cause of the great difference of result with this prussiate 

 depends no doubt on some mutual change with the prussic acid 

 that deserves examination. 



\\ ater absorbed per cent., 39 ; hydrogen liberated, 27*56 : — 



Acid gas 51 *4/5 



Hydrogen 15*085 



Azote 33*44 



If a small portion of the hydrogen and azote were also absorbed 

 by water (as is very probable), the results will then come close to 

 our calculated proportions. 



Phosphorus condensed per cent., 11*11. The residuum had a 

 portion that precipitated metallic solutions equal to 35*55 per cent. 

 of mixi (I gas. The remainder contained hydrogen per cent, of the
