OXIGENATED MURIATIC ACID GAS.

Experiment XI.

Accension of expressed oils at the surface of water, by oxigenatedmuriatic acid gas.

Put into a glass cylinder one part of oxigenated muriate ofpotash; add to it three or four of water, and half a part of oil ofolives, or of linseed. On adding to it four or five parts of con-centrated sulphuric acid, a violent action takes place, much char-coal becomes deposited, and a multitude of ignited sparks passthrough the black fluid, exhibiting a beautiful phenomenon. Onadding an additional quantity of oxigenated muriate of potash andsulphuric acid, the whole mass takes fire and burns with a denseyellow flame.

Experiment XII.

Acccnsion of phosphorus in oxigenated muriatic acid gas, underthe surface of ivaler.

Let fall into a wine-glass, or rather into a long cylinder, two-thirds filled with water, one part of phosphorus, and two of ox-igenated muriate of potash. On adding to this mixture three orfour parts of sulphuric or nitric acid, the phosphorus takes fire,and burns vividly under the surface of the fluid: on agitating themixture, streams of ignited sparks pass through the water rapidly.

Remark. ..This and the two preceding experiments requirecaution. The operator ought to be distant during the atfusion ofthe acids, or the addition of tire combustible body, which aresometimes thrown out of the vessel to a considerable distance.

Experiment XIII.

Nitrous gas and oxigenated muriatic acid gas, readily uniteand produce nitro-muriatic acid.

This may be shown by sending up into a receiver filled withoxigenated muriatic acid gas, bubbles of nitrous gas; die mixture
