through the bottle. If it were desired to give air enriched with oxygen instead 

 of nearly pure oxygen, this could be done to any extent by reducing, under the 

 guidance of the valve, the flow of oxygen from the bottle. 



Oxygen as it comes from the bottle is said to be cold from expansion, though 

 this effect must be more or less neutralised by friction in the narrow outlet and 

 conduction from the massive valve. Probably the temperature of the issuing gas 

 is lower the greater the rate of exit. The oxygen is certainly dry and will be 

 fitter for respiration after passing over warm water. Also, through the action of 

 the reservoir, the bottle will last more than twice as long.
