The use of charcoal in filters is acknowledgeduniversally, and as a constituent of gunpowder it is im-portant. Carbon is not easily affected by the atmospheric air,or in the earth; so in many instances wood is charredbefore being driven into the ground ; and casks for waterare prepared so. Soot is carbon in a pulverised condition,and Indian ink is manufactured with its assistance. The preparation of wood charcoal gives occupation tomen who are frequently wild and untutored, but the resultsof their labour are very beneficial. Care should be takennot to sleep in a room with a charcoal stove burning,unless there is ample vent for the carbonic acid gas, for it. lOO chemistrv will cause suffocation. Lampblack is obtained by holdinga plate over the flame of some resinous substance, whichdeposits the black upon it. There is a special apparatusfor this purpose. Carbon combines with oxygen to make carbonic acidgas, as we already mentioned, and in other propor-tions to form a more deadly compound than the former is the dioxide (COJ, the latter the monoxide,or carbonic oxide (CO). The dioxide is the more im- =--.,?Sa^s ^3
