Atmofpheric air alfo decompofes hepatic air. ^ It is found in many mineral waters, and par ticularly in the hot baths of Aix-la-Chapelle.

Mixed with two-thirds of common or nitrous air, it mdy be fet on fi re by the flame of a candle, like the inflammable air of the laft Seftion ; the veflel is filled with a white thick irnoke, which fmells like volatil fpirit of fulphur; and a white powder is depofited, which confifls of ful- phor. It detonates with dephlogiflicattd air. 3. It is mifcible with water, and communicates to it a flat, but penetrating anti very difagreeabie flavour. 4- It kills aniinals, if inclofcd therein. 5* It extinguiflies alfo the flame of a Candle when immerfed 111 it. 6.
