of Oxy muriatic Gas and Oxygene. % ^ 
mony, which so readily burn in oxymuriatic gas, did not act 
upon the explosive gas in the cold : and when they were in- 
troduced into it, being heated, it was instantly decomposed, 
and its oxygene set free ; and the metals burnt in the oxy- 
muriatic gas. 
When sulphur was introduced into it, there was at first no 
action, but an explosion soon took place : and the peculiar 
smell of oxymuriate of sulphur was perceived, 
Phosphorus produced a brilliant explosion, by contact with 
it in the cold, and there was produced phosphoric acid and 
solid oxymuriate of phosphorus. 
Arsenic introduced into it did not inflame ; the gas was 
made to explode, when the metal burnt with great brilliancy 
in the oxymuriatic gas. 
Iron wire introduced into it did not burn, till it was heated 
so as to produce an explosion, when it burnt with a most bril- 
liant light in the decomposed gas. 
Charcoal introduced in it ignited, produced a brilliant flash 
of light, and burnt with a dull red light, doubtless owing 
to its action upon the oxygene mixed with the oxymuriatic 
gas. 
It produced dense red fumes when mixed with nitrous gas, 
and there was an absorption of volume. 
When it was mixed with muriatic acid gas, there was a 
gradual diminution of volume. By the application of heat the 
absorption was rapid, oxymuriatic gas was formed, and a dew 
appeared on the sides of the vessel. 
These experiments enable us to explain the contradictory 
accounts that have been given by different authors of the pro- 
perties of oxymuriatic gas.
