 up and down like gas 



The combustion chamber consists of a perforated metal cone, surrounded by a cotton wick which is protected 

 <y an asbestos lining. 



The wick requires no replacement or attention, the lining renders it indestructible even if the spirit is allowed 

 o burn out. 



The air-control valve determines the supply of air to the combustion chamber. 



The control in the base operates the air-control valve, and by this means the flame is turned up and down 

 ike gas. When turned full on it is so powerful that it will boil a quart of water in 6 minutes. 



The kettle-stand is combined with a reflector, and is separable from the lamp to facilitate cleaning.
