COMPOUND OF CARBONIC OXIDE AND OXIMURIATIC GAS. g^

 with a smaller proportion. 



Tin fused in the ^as in a bent glass tube over mercury, Decomposed 

 by means of a spirit lamp, rapidly decomposed it; the liquor b y tin > 

 of Libuvius was formed ; and when the vessel had cooled, 

 tiv is not the least change of the volume of the gas per- 



cepti >!e; but the gas had entirely lost its offensive odour, 

 and was merely carbonic oxide; for like carbonic oxide it 

 burut wnh a blue flame, afforded carbonic acid by its com-* 

 bustion, and was not absorbable by water. 



The effects of zinc, antimony, and arsenic heated in the zinc, antimony 

 gas, were similar to those of tin ; compounds of these metals and arsenic, 

 and chlorine were formed, and carbonic oxide in each ex* 

 periment was 1 berated equal in volume to the gas decom- 

 posed. In each instance the action of the metal was quick; 

 the decomposition being completed in less than ten minutes: 

 but though the action was rapid, it was likewise tranquil, 

 no explosion ever took place, and none of the metals be- 

 came ignited or inflamed. 



The action even of potassium heated in the gas was not potassium* 

 violent. But from the great absorption of gas, and from 

 the precipitation of carbon indicated by the blackness pro- 

 duced, not only the new gas, but likewise the carbonic oxide, 

 appeared to be decomposed. 



The white oxide of zinc heated in the gas quickly decom- white oxide of 

 posed it, just as readily indeed as the metal itself; there was zinc » 

 the same formation of the butter of zinc; but instead of 

 carbonic oxide being produced, carbonic acid was formed; 

 and, as usnal, there was no change of volume. 



The protoxide of antimony fused in the gas rapidly de- an( j Drotox -j e 

 composed it ; the butter of antimony and the infusible per-* of antimony, 

 oxide were formed ; there was no change of the volume of 

 the gas, and the residual gas was carbonic oxide.

 no apparent change; the volume of the gas was unaltered, sed by sulphur,

and its charactenstic smell was undiminished. 



Mixed with hidrogen or oxigen singly, the gas was not or hidrogen or 



inflamed by the electric spark, but mixed with both, in pro- oxigen singly s

one of the latter to two parts of the gas, a violent explosion
