54 Mr. Faraday on two new compounds 
nearly opaque. If the heat be raised still higher, as when 
the substance is passed through a red hot tube, it is decom- 
posed, chlorine is evolved, and another chloride of carbon, 
which condenses into a fluid, is obtained. This shall be 
described presently. 
It is not readily combustible ; when held in the flame of a 
spirit lamp, it burns with a red flame, emitting much smoke 
and acid fumes; but when removed from the lamp, com- 
bustion ceases. In the combustion that does take place in 
the lamp, the hydrogen of the alcohol, by combining with 
the chlorine of the compound, performs the most important 
part ; nevertheless, when the substance is heated red in an 
atmosphere of pure oxygen, it sometimes burns with a bril- 
liant light. 
It is not soluble in water at common temperatures ; or only 
in very small quantity. When a drop or two of the alcoholic 
solution is poured into a large quantity of water, it renders 
it turbid from the deposition of the substance. It does not 
appear that hot water dissolves more of it than cold water. 
It dissolves in alcohol with facility, and in much greater 
quantity with heat than without. A saturated hot solution 
crystallizes as it cools, and the cold solution also gives crys- 
tals by spontaneous evaporation. When poured into water, 
the chloride is precipitated, and falls to the bottom in flakes. 
If burnt, the flame of the alcohol is brightened by the pre- 
sence of the substance, and fumes of muriatic acid are libe- 
rated. Solution of nitrate of silver does not produce any tur- 
bidness in it, unless it be in such quantity that the water throws 
down the substance ; but no chloride of silver is formed. 
It is much more soluble in ether than in alcohol, and more
