654 GlyOSSARY. 



Car-bon-Di-ox-ide. The result of the union of oxygen and carbon in 

 complete combustion. Two parts of oxygen uniting with one part 

 of carbon. It is the gas which is found in wells and mines, and 

 is produced and given off by burning of kerosene and oil 

 lamps. It is also given off from the lungs while breathing. It 

 is colorless gas, slightly heevier than air, and will produce suffoca- 

 tion and death if the air contains a large percentage of the gas. 

 I^arge lamps and oil-stoves burning in a room, require a large amount 

 of ventilation to keep the air pure. 



Car-bon-Mo-nox-ide. This is also a union of carbon and oxygen, but 

 is formed as a product of partial combustion, as when the dampers

 complete combustion. It is seen above the coal in a blue flame. It 

 will penetrate even iron, is poisonous and very dangerous. Avoid 

 closing the dampers in the stove pipes as this often causes it to pass 

 out into the room during the night, causing the sleeping persons to be- 

 come asphyxiated.
