 usual. But let us first place in the bottle a 

 red-hot coal and wait a few minutes to give 

 time for the carbon to be dissolved in the air ; 

 then withdraw the coal and replace it by a 

 lighted candle. This will burn dim and go 

 out. However carefully we introduce it we 

 shall not be able to make it burn inside the 

 bottle until the gaseous contents are renewed 

 and replaced by pure air. 



Air impregnated by dissolved carbon is 

 deadly for man. If this formidable gas is 

 breathed to any extent, the mind grows dull, 

 numbness ensues, strength departs and, with- 

 out timely help, death will follow. We have 

 heard of unfortunate people who, voluntarily 

 or accidentally, have been killed or, as it is 

 called, asphyxiated, by a charcoal stove 

 lighted in a close room. The air impregnated 

 with dissolved carbon is the cause of this 

 lamentable result. It produces first violent 

 headache and general discomfort ; then the 

 loss of feeling, giddiness, nausea and extreme 

 weakness. If this condition is prolonged life 

 is in danger.

 pass out by a chimney but are scattered in
